Abstract

Purpose

The purpose of this paper is to determine the influence of low-fat and high-fat diets supplemented with dextrin obtained from corn starch on the numbers and relative proportions of enteric bacteria Bacteroidetes (Bacteroides, Prevotella), Actinobacteria (Bifidobacterium) and Firmicutes (Clostridium, Lactobacillus). Moreover, basic indicators of gastrointestinal function (among other things: epidydymal fat mass, mass with contents, pH in the colon, cecum, small intestine, fecal enzymes were investigation) and short-chain fatty acids are analyzed.

Design/methodology/approach

In vivo experimental studies in rats (analized samples of the ileal, cecal and colonic digesta; pH; blood serum; fecal enzymes); determination of the number of bacteria – fluorescence in situ hybridization; and determination of type and concentration SCFA – HPLC were considered.

Findings

No statistically significant differences in final body weight were found between rats fed low-fat and high-fat diets supplemented with dextrin. In rats fed the low-fat diet with dextrin, the gut microbiota composition was as follows: 42.74 percent Bacteroises and Prevotella (Bacteroidetes), 35.28 percent Clostridium and Lactobacilllus (Firmicutes) and 21.98 percent Bifidobacterium (Actinobacteria), while in rats fed the high-fat diet with dextrin it was similar. Irrespective of the diet type, supplementation with dextrin enhances bacterial glycolytic activity and the cecal production of total SCFAs, with strongly increased propionate and decreased butyrate fermentation.

Practical implications

Dextrin may enrich food or be a component of functional foods.

Originality/value

Dextrin from corn starch may contribute to changes in the composition of intestinal microbiota.

Abstract

A pet phrase of a competent teacher of mathematics years ago was: “Figures by themselves have no meaning.” And everyone knows that statistics are deceitful things. Mr. W. Johnston's batting average in this country this year was 102, although his position in the batting order was never higher than number 11. He is reported indeed to have said of himself: “I am the ferret of the Australian team; they put me in after the rabbits.” But his position at the head of the batting averages could lead to a preposterously erroneous conclusion.

Abstract

In these days of jargon and slang, to the purist it must seem that little is described by its real name, that is, during conversation. Most people refer to the city as “the smoke” and the city‐dweller's pseudonym for the country is “out in the sticks”, which, of course, could mean that “the sticks” are kindling to a fire that has not been lit, with the city “smoke” as the end‐product of the fire that is burning up those who rush hither and thither in its bedlamite streets and ugly office blocks. The cottage, the church and inn no longer completely fill the lives of the villagers; they now have piped water supplies, electricity and telephones; deep freezers, colour television and cars; they have moved closer to the city standards of comfort and convenience without losing any of the enduring qualities which make them different. And the countryman is very different to the town‐dweller—in outlook, habit and countenance. Even the villager who works in the town and city, and nowadays there are many of them, would not change his home in the country for a flat or terrace house in a mean street, despite the long journeying to and fro. At one time, it had to be a special type of girl who chose a home in these rural settings, with few or perhaps no neighbours and no corner‐shop, but now more and more are realizing that life in a village is easier on the whole family.

Abstract

On May 12th the case for the abolition of night baking from the operatives' point of view was placed before the Committee appointed by the Government to investigate the subject under the chairmanship of Sir WILLIAM MACKENZIE. MR. BANFIELD, the General Secretary of the Union of Operative Bakers, Confectioners and Allied Workers, said there was a general demand for legislation prohibiting night work. Bakers looked old before their time, and the Chairman of the Richmond Tribunal had stated that no baker passed A1 had ever been before him. Witness urged that new bread was not so important as the health of the night worker, although new bread could be supplied under a system of day work. The only ground for night work was that it was in the interests of certain employers, but he said that 80 per cent. of the employers had enough ovens and plant to carry on a system of day work. He suggested the prohibition of night baking between the hours of 11 p.m. and 5 a.m., with legal provision for an extension of the prohibited hours at intervals. He added that 90 per cent. of the operative bakers would prefer day work. Continued night work was bad for the health of the baker. The returns showed that the rate of mortality from bronchitis among working bakers was abnormally high. This was due to the constant change from a heated atmosphere to a cooler one. The mortality from phthisis was slightly higher than the average, while the figures for suicide were considerably higher than the average Replying to the Chairman, MR. BANFIELD said that there need be no increase in the price of bread if night baking was prohibited, as any expense which might be occasioned to the employer could come out of the profits the employer now put into his pocket, instead of using it to extend his plant. His experience was that the bulk of the bread was not sold till late in the afternoon. Witness desired the abolition of the order prohibiting the sale of bread less than twelve hours old. He said that if the order was rigidly enforced it would itself solve the problem of night baking. He did not think, however, that there was sufficient justification for continuing the order, which, in his opinion, should be revoked and replaced by an enactment prohibiting night‐baking. The order, he said, was fairly extensively ignored, simply because, in his opinion, the local food committees refused to prosecute, or would not inspect. MR. CANNON, the owner of fifty bakers' shops in working districts of London, declared that the waste of bread resulting from the order prohibiting the sale of bread less than twelve hours old was enormous. The Food Controller in introducing the order, had introduced a new business—the stale bread industry, which consisted in the buying up of stale bread. He was not prepared to say what was done with it but it was not being used as bread. A strike of bakers would be futile as it would simply mean that housewives would bake their own bread, and after a little practice they would do it better than any baker.

Abstract

Purpose

The purpose of this paper is to present a case report involving environmental performance analysis of a small Brazilian business from the foundry industry.

Design/methodology/approach

An environmental performance indicator was developed (Iepa) which is calculated taking into consideration the weighting of potential environmental impacts of each residue/sub product generated, the relative spatial dispersion which each residue/sub product can reach, and the adequacy evaluation of final allocation accomplished by the company for each residue/sub product.

Findings

Despite the evidence that the corporation do not conduct washing of gases emitted from the chimney of the foundry furnace, which consists an environmentally inadequate attitude, the result of Iepa=97.50 percent was obtained. This favorable result is due to the adequate allocation given to residues generated in greater volume in the process, the molding sand. This sand is addressed to an industrial landfill, which is an environmentally adequate practice and approved by competent environmental authorities.

Practical implications

The method used can be applied to measure the environmental impact generated by any business of the foundry sector industry.

Originality/value

The originality of the work is in the developed method, which takes into account: the potential impact of each residue/sub product generated, the amount of each residue/sub product generated in a given time period, the dispersion that each residue/sub product can attain, and the evaluation of eventual allocation of each residue/sub product.

Abstract

“Streets broad and narrow”. In terms of shops and retail trade, it was always the narrow streets of town centres which attracted the trade, although the shops were small cramped for space, but always a cosy, friendly air. Few ever became vacant and although interspersing chain shops seemed to break the rhythm, most were privately owned, run through the years by generations of the same family. The shops removed the proverbial meanness of narrow streets; the lights, the shopping crowds, especially on Saturday nights; shop frontmen bawling their prices, the new boys calling the late editions—all this made shopping an attractive outing; it still does. There were the practical advantages of being able to cross and re‐cross the street, with many shops on both sides within the field of vision. The broad highway had none of these things and it was extremely rare for shops to exist both sides of the street, and still less to flourish. It is much the same to this day. Hygiene purists would find much to fault, but it was what the public wanted and curiously, there was very little food poisoning; it would be untrue to say outbreaks never occurred but they were extremely rare.

Abstract

Sago starch (Metroxylon sagu Rottb.) is one of the starches imported into Japan. Recently, sago starch has been promoted as a healthy type of starch because it is gluten-free and non-allergenic. This study aims to identify the factors affecting sago starch import demand during the period 1978–2017 in Japan by using a double logarithmic linear function. The study revealed that the price of sago starch, GDP, aging population rate and tariff-rate quota policy are significant factors influencing sago starch importation in Japan.

Abstract

It is a matter of common knowledge that beer, in its several varieties, is by no means the same thing to‐day as it was a generation or less ago; the progress of chemical and biological knowledge on the one hand, and the keenness of competition on the other, have led to great alterations both in the materials used in its production and the methods by which it is produced. Exact or reliable knowledge about this, however, is far from being common; vehement assertions are made that all or almost all the changes are for the better, and also that beer is now a manufactured chemical product of deleterious nature, in which little or nothing of genuine material is used. Such statements are rendered unacceptable by the existence of self‐interest on one side and prejudice on the other. A short account of some of the facts concerned may, therefore, be of service.

Abstract

That the introduction of the Control system should have given rise to a considerable amount of criticism, both appreciative and adverse, was naturally to be expected. The appreciative remarks which have appeared in the press, and those also which have been privately communicated to the directors, indicate that the subject has been intelligently considered, and in some cases carefully investigated and studied. The opinions given are worth having on account of the position and influence of hose who have given them, and on account of the obvious freedom from bias which has characterised them. This is so far satisfactory, and goes to show that the success which has attended the working of the Control system abroad may well be expected to attend it in this country as soon as it is sufficiently well known to be appreciated by the manufacturers and vendors of good and genuine products, and by the general public, whose best interests it cannot but serve.

Abstract

Restructured shrimp made with three different formulations were evaluated using subjective and objective texture analysis. The three formulations showed statistical similarities with breaded whole shrimp in terms of gumminess and oily cover in mouth, and differed in relation to firmness, elasticity, cohesivity, adhesivity, moisture release, stickiness in mouth and overall texture impression. The objective texture evaluation showed significant differences in respect to cohesivity, adhesivity and gumminess between breaded whole shrimp and the three formulae, and in reference to hardness, between formulations.
