The purpose of this paper is to present an econometric model to empirically analyze the influence of production patterns and transaction style on raw milk quality. More specifically, the paper examines the effects of these institutions on both nutrition and safety aspects of raw milk quality.

Using data collected from 396 households in Inner Mongolia, this paper adopts a multiple linear regression model (OLS/FGLS) and a zero-inflated Poisson regression model to test two hypotheses proposed according to theory and descriptive analysis.

The empirical results indicate that both production pattern and transaction style significantly affect raw milk quality. Production pattern has a more significant effect on raw milk nutrition, while transaction style has a more significant effect on raw milk safety.

Current government policies focus on reducing household production and regulating private milk collection stations. From a comprehensive quality perspective, these policies are not effective in that they cannot guarantee raw milk safety and have little effect on improving raw milk nutrition. Alternatively, promoting dairy farmers' specialized cooperatives may be a more effective policy measure.

In contrast to other studies, this paper adopts a comprehensive quality perspective that examines both nutritional and safety characteristics rather than focusing on any single quality indicator, separately analyzing the factors influencing raw milk nutrition and raw milk safety. Therefore, the conclusion of this paper provides a new perspective in addressing the current raw milk quality problems facing China's dairy industry.

The purpose of this paper is to examine the effect of health information and sensory attributes on consumer’s propensity to upgrade and their willingness to pay (WTP) for pasteurized milk in Ethiopia.

The authors used a framed market experiment with 160 participants in 14 central locations in urban Ethiopia. The authors used a double hurdle model to analyze consumer willingness to shift to pasteurized milk and their WTP for quality attributes in pasteurized milk.

Consumers are willing to pay a 4 percent premium for quality attributes in pasteurized milk. Male and employed participants are willing to shift and pay a premium for pasteurized milk. Conversely, consumers with more children, higher income, and higher raw milk consumption are less likely to shift to pasteurized milk. These results also show that taste is negatively related to consumer propensity to upgrade to pasteurized milk. Further, about half of the consumers who were provided with health information are willing to pay a premium of 11 percent for pasteurized milk, whereas others would pay only 6 percent. After providing the treatment group with health information, those consumers with higher income, old people and consumers with children are less likely to shift to pasteurized milk. Overall, consumer preference for raw milk is the result of taste, perceived nutrition and perceived health benefits. The study points at a segmented milk market and the consequent need for the provision of a targeted milk market promotion.

The application of experimental auctions in developing countries requires an extensive learning exercise for participants.

The authors used a non-hypothetical valuation mechanism to unravel the effect of subjective and intrinsic milk attributes in fluid milk choice decisions and its variation across socio-economic groups in a developing country context.

The purpose of this paper is to investigate if there is a difference in hygiene parameters of raw milk produced in organic and conventional farm of similar size. In parallel, the aim was to determine if there are differences in pasteurized organic and conventional milk samples delivered on the market.

Raw milk samples were analyzed for aerobic colony count (ACC), somatic cell count (SCC), acidity, temperature, fat and protein content. On the other side, final products of organic and conventional pasteurized milk with 2.8 percent declared milk fat were analyzed for Raman spectroscopy, color change and sensorial difference.

Results of raw milk analysis showed statistically significant differences in fat content, SCC, acidity, temperature and ACC (p<0.05). It is of note that ACC for organic milk were lower for approx. 1 log CFU/ml compared to conventional milk samples. Pasteurized organic milk samples had a significantly higher L* value than those samples originating from conventional farms, indicating that organic is “more white” compared to conventional milk. According to the results of triangle test, with 95 percent confidence no more than 10 percent of the population is able to detect a difference.

A limitation of this research is the fact that good veterinary practices at farms, namely, animal health and adequate usage of medicine for treating the animals, animal welfare and animal feeding were not analyzed.

This study analyzed potential differences in organic and conventional milk at two important production stages of the milk chain – at receipt at dairy plant (raw milk) and perceived by consumers (final product).

The dairy industry needs to make important decisions regarding its supply chain. In a context with many available suppliers, deciding which of them will be part of the supply chain and deciding when to buy raw milk is key to the supply chain performance. This study aims to propose a mathematical model to support milk supply decisions. In addition to determining which producers should be chosen as suppliers, the model decides on a milk pickup schedule over a planning horizon. The model addresses production decisions, inventory, setup and the use of by-products generated in the raw milk processing.

The model was formulated using mixed integer linear programming, tested with randomly generated instances of various sizes and solved using the Gurobi Solver. Instances were generated using parameters obtained from a company that manufactures dairy products to test the model in a more realistic scenario.

The results show that the proposed model can be solved with real-world sized instances in short computational times and yielding high quality results. Hence, companies can adopt this model to reduce transportation, production and inventory costs by supporting decision making throughout their supply chains.

The novelty of the proposed model stems from the ability to integrate milk pickup and production planning of dairy products, thus being more comprehensive than the models currently available in the literature. Additionally, the model also considers by-products, which can be used as inputs for other products.

In every industry there are resources. Some are moving, others more fixed; some are technical, others social. People working with the resources, for example, as buyers or sellers, or users or producers, may not make much notice of them. A product sells. A facility functions. The business relationship in which we make our money has “always” been there. However, some times this picture of order is disturbed. A user having purchased a product for decades may “suddenly” say to the producer that s/he does not appreciate the product. And a producer having received an order of a product that s/he thought was well known, may find it impossible to sell it. Such disturbances may be ignored. Or they can be used as a platform for development. In this study we investigate the latter option, theoretically and through real world data. Concerning theory we draw on the industrial network approach. We see industrial actors as part of (industrial) networks. In their activities actors use and produce resources. Moreover, the actors interact − bilaterally and multilaterally. This leads to development of resources and networks. Through “thick” descriptions of two cases we illustrate and try to understand the interactive character of resource development and how actors do business on features of resources. The cases are about a certain type of resource, a product − goat milk. The main message to industrial actors is that they should pay attention to that products can be co-created. Successful co-creation of products, moreover, may require development also of business relationships and their connections (“networking”).

The purpose of this paper was to evaluate health conditions prior to and at least two months after the start of consuming raw fermented milk (RFM) products.

One-Item health score, 1-item immunity score, immune status (ISQ), mood, bowel and skin conditions were rated for the period prior and post switching to RFM products. A linear mixed model was used to evaluate the post to prior RFM health and mood scores, taking into account gender, location of living and health group. Data from 390 participants (mean age of 54 years old) were included for the analysis, of which 277 (45 per cent) were allocated to the poor health group. Participants were allocated to the poor health group if they reported being immune depressed or suffering from a chronic disease prior to RFM; otherwise, they were allocated to the normal health group.

The highest intake of RFM was from RF kefir. Post RFM, people consumed around 1 glass (200 ml) of RF kefir per day. After switching to RFM, significant improvements on health and mood scores were reported. The strongest improvements after switching to RFM consumption were seen in subjects from the poor health group. With the exception of skin score, all measured health items significantly improved (p < 0.001). Health, immunity, bowel and mood scores increased with around 20 per cent in the poor health group and around 8 per cent in the normal health group. Women had more health complaints prior to RFM and had stronger health improvement post RFM compared to men. Bowel and mood scores were overall lower in women than in men. Living location had no significant impact on RFM-related health changes. This consumer survey suggests that positive health and mood changes are associated with the consumption of RFM products.

The consumption of RFM products improved the self-reported health status of adults. Immune-depressed people or people suffering from a chronic disease prior to RFM reported the strongest impact on their health, immunity, bowel and mood scores post switching RFM consumption compared to people with a normal health.

The connotations, associations, custom and usages of a name often give to it an importance that far outweighs its etymological significance. Even with personal surnames or the name of a business. A man may use his own name but not if by so doing it inflicts injury on the interests and business of another person of the same name. After a long period of indecision, it is now generally accepted that in “passing off”, there is no difference between the use of a man's own name and any other descriptive word. The Courts will only intervene, however, when a personal name has become so much identified with a well‐known business as to be necessarily deceptive when used without qualification by anyone else in the same trade; i.e., only in rare cases. In the early years, the genesis of goods and trade protection, fraud was a necessary ingredient of “passing off”, an intent to deceive, but with the merging off Equity with the Common Law, the equitable rule that interference with “property” did not require fraudulent intent was practised in the Courts. First applying to trade marks, it was extended to trade names, business signs and symbols and business generally. Now it is unnecessary to prove any intent to deceive, merely that deception was probable, or that the plaintiff had suffered actual damage. The equitable principle was not established without a struggle, however, and the case of “Singer” Sewing Machines (1877) unified the two streams of law but not before it reached the House of Lords. On the way up, judical opinions differed; in the Court of Appeal, fraud was considered necessary—the defendant had removed any conception of fraud by expressingly declaring in advertisements that his “Singer” machines were manufactured by himself—so the Court found for him, but the House of Lords considered the name “Singer” was in itself a trade mark and there was no more need to prove fraud in the case of a trade name than a trade mark; Hence, the birth of the doctrine that fraud need not be proved, but their Lordships showed some hesitation in accepting property rights for trade names. If the name used is merely descriptive of goods, there can be no cause for action, but if it connotes goods manufactured by one firm or prepared from a formula or compsitional requirements prescribed by and invented by a firm or is the produce of a region, then others have no right to use it. It is a question of fact whether the name is the one or other. The burden of proof that a name or term in common use has become associated with an individual product is a heavy one; much heavier in proving an infringement of a trade mark.

Although a comparatively rare disease in Great Britain, cases of trichinosis have been reported from different parts of the country from time to time. Statistics show that during the present century only 59 cases were reported prior to the Wolverhampton outbreak in 1941. Trichinosis is a parasitic disease. The Trichina spiralis lives in the small intestine, the female measuring about ⅛ in. in length and the male 1/16 in. The ova emerge as minute hair‐like embryos which burrow from the intestines to the musculature of the host. Thus if man consumes pork containing live trichinæ the larvæ are freed from their capsules by the action of the gastric juices, and maturity is attained in the small intestine. The female grows rapidly and at the end of a week gives rise to a swarm of a hundred or so embryos. The burrowing process starts again, and this boring into muscles produces intense muscular pains, swelling and tenderness, high fever, and other symptoms. The effects of cooking and preserving on infected meat are described by Mr. C. R. A. Martin, who says that thorough cooking for twenty minutes at a temperature above 150° F. is sufficient to destroy all trichinæ, providing the whole of the meat is subjected to this temperature for a similar period. It is obvious, therefore, that in domestic cookery boiling would be preferable to roasting in order to kill live parasites. Only very low temperatures (0°–5° F.) applied for three weeks have any effect on the vitality of trichinæ. Dry salting will kill all trichinæ in surface layers of the meat after exposure to the salt for fourteen days, but in the case of large bacon or hams a much longer exposure of eight to twelve weeks would be necessary, together with brine pumping of the thicker parts. Pickling in brine, if the brine is sufficiently strong, is a surer method of destroying larvæ. Smoking, partly through heat and partly the resinous products of burning pine sawdust, also has a slight effect on their vitality. It has, howver, been suggested that Memo. 62/Foods issued by the Ministry of Food, which recommends that a carcase affected with trichinosis should be condemned, is out of date and that there should be no grounds for ignoring the possibility of the disease during the ordinary routine meat inspections. In this connection, the recent circular dealing with outbreaks of cysticercus bovis infestation of cattle in different parts of the country should serve as a warning. A further warning is given in a letter to the British Medical Journal in which the writer deplores the way in which corned beef is served to the public. The procedure in the majority of shops, says the writer, is to open a large tin of corned beef and place the contents on a wooden cutting board. The same knife used for cutting uncooked sausages, uncooked beef, uncooked pork, and slabs of sausage meat is used, without any attempt at cleaning it, for cutting slices of corned beef. The writer goes on to say that the corned beef is then placed on the weighing machine plate, which quite normally in a butcher's shop is covered with blood. Further contact between the uncooked meat and corned beef is made when the wrapped (and sometimes unwrapped) corned beef is placed on top of the raw meat. Should parasitic worms or cysts which have evaded the eye of the meat inspector be present in the raw meat, they will be transferred to the corned beef by knives, by butchers' hands, by scales, and by direct contact with the raw meat. Many veterinarians have pressed for the detailed examination of pig carcases for trichinosis which would necessitate the removal of suspected muscle by means of a trichinoscope, but no such instrument is in existence in the abattoirs of this country. The whole operation, which is carried out as a matter of routine inspection in many Continental abattoirs, takes only a few minutes. Should simple safeguards in feeding and inspection be adopted, it seems fairly evident that the absence of a trichinoscope need not be regarded as a serious gap in our public health services, but the rarity of outbreaks of the disease in this country must not lead to complacency or to ignoring the possibility of its presence during the normal course of meat inspection.

From earliest times the land and all it produced to feed and sustain those who dwelt on it was mankind's greatest asset. From the Biblical “land of milk and honey”, down through history to the “country of farmers” visualised by the American colonists when they severed the links with the mother country, those who had all their needs met by the land were blessed — they still are! The inevitable change brought about by the fast‐growing populations caused them to turn to industry; Britain introduced the “machine age” to the world; the USA the concept of mass production — and the troubles and problems of man increased to the present chaos of to‐day. There remained areas which depended on an agri‐economy — the granary countries, as the vast open spaces of pre‐War Russia; now the great plains of North America, to supply grain for the bread of the peoples of the dense industrial conurbations, which no longer produced anything like enough to feed themselves.

At a meeting of the Nutrition Panel of the Food Group of the Society of Chemical Industry, Dr. Joseph Needham, of the Biochemical Laboratory, University of Cambridge, speaking on “ The Biological Nature of the Egg,” pointed out what complex structures were the eggs of birds and other vertebrates. In fact the embryo, which is eventually to develop into the new animal, only occupies a very small space within the total egg. The remainder serves, in one way or another, to keep the organism alive until it is hatched. It is interesting to note that this is not the case in lower animals. The octopus in its egg is not supplied by its mother with enough copper but must obtain more for itself from the surrounding sea. Newts and frogs in their eggs also must to some extent look after themselves. Birds' eggs, however, represent a type of perfectly “closed box” structure which requires many ingenious devices in order to survive. One of these, through which the bird saves itself from being poisoned by its own by‐products, is the fact that the developing embryo does not excrete nitrogen as urea but in the form of uric acid which is more easily deposited as crystals.—Dr. Ethel M. Cruickshank, of the Department of Agriculture, Cambridge, who spoke on the “ Chemical Composition of the Egg,” pointed out that the hen was a physiological machine for turning raw materials into human foodstuffs. The amount of such human food which the hen could produce in a day depended on a number of factors, but to a large extent it was true to say that the bigger the hen the larger the egg. The number of eggs which a hen would lay in a year was a different matter, but an interesting point was the fact that high production had little or no detrimental effect on the quality of the eggs. In considering the composition of the egg one must divide it into three parts. The shell was principally made up of calcium carbonate, although small amounts of magnesium, phosphorus and organic matter were present. The white was composed of four different kinds of protein and could be divided into layers of thick and thin white. The proportion of thick to thin white influenced the culinary value of the egg. Together, the four proteins in the white contained the essential amino acids which made “ first class ” protein. Egg white contained minerals and also supplied valuable amounts of vitamin B. The yolk contained two proteins which were also shown to be of “ first class ” quality. Besides protein the yolk contained 30 to 32 per cent. of fat. Numerous minerals were present, including relatively rich amounts of easily assimilable iron. Vitamins A, D, B1 and B2 were also present. The anti‐rachitic vitamin D was of great significance in the diet. Dr. Cruickshank also discussed the factors in the diet of the hen which might give the yolk an unpleasant taste or a strange colour. Although the amount of fat, and hence the total food value of the egg, could only be influenced to a slight extent by the diet of the hen, the nature and flavour of the egg could be very strikingly altered by feeding mashes containing, for example, hemp seed or linseed oil. As regards vitamins, it was essential that plenty of these should be present in the diet of the hen in order that her egg might be of high nutritive value. As regards minerals, it was very well known that by feeding a hen a diet which was short of calcium a thin shell was obtained. However, the calcium content of the yolk and white were not affected. The amount of iodine in eggs was affected by the amount in the hens' food, although iron and copper appeared to be independent of the amount present in the diet.—Dr. S. K. Kon, of the National Institute for Research in Dairying, Reading, spoke on the nutritive importance of eggs in the diet. He stressed that eggs share with milk the ability to cover nutritive requirements during the period of rapid development. The vitamins, minerals and “ first class ” protein in eggs made them one of the protective foods. In particular, eggs supplemented very well the proteins present in cereals. Dr. Kon showed in detail how eggs contribute to the various factors of a good diet.—Dr. R. B. Haines, of the Low Temperature Research Station, Cambridge, spoke on the preservation of eggs. He showed how hens' eggs were in a state of rapid change. The aim of storage was to retard or stop this change and prevent the attack of outside agencies such as micro‐organisms. Although storage only affected the nutritive value of eggs to a very minor degree, any loss of palatability and cooking quality was a clear indication that certain slight chemical changes had taken place. Dr. Haines mentioned three methods for the large‐scale storage of eggs. The first was cold storage, the second, storage with the partial addition of CO2, and the third, full gas storage. For other purposes, drying or freezing could be used. Problems connected with the storage of eggs led to the consideration of questions of production and handling. For example, “ thick white ” was apparently due to the individual hen. Again, spoilage of eggs by the invasion of bacteria was influenced by the structure of the egg‐shell, which might vary greatly in successive eggs from the same hen or by the “ washing ” treatment which the eggs received. Among many other topics upon which Dr. Haines touched were “ swollen ” and “ flabby ” yolks due to loss of moisture, “ watery whites,” “ sunken ” and “ sided ” yolks due to chemical changes, and eggs with “ whiskers,” due to the growth of fungus on the shell.—Miss Mary Andross, of the West of Scotland College of Domestic Science, Glasgow, gave the final paper on the subject of “ The Cooking of Eggs.” Research in domestic science concerned itself with what effect such factors as temperature, time, rate of cooking, acidity, or the addition of salts, might have on the nutritive properties of eggs which were boiled, poached, fried, scrambled or made into omelets, custards, mayonaise, meringues, angel cakes, or sponge cakes. Another important factor which was the subject of scientific investigation was the effect of the age of the egg in relation to its cooking qualities. Miss Andross also discussed the waste of food value which might take place in different methods of cooking, and she concluded by discussing the effects which different treatments might have on the digestibility of the food.
