Abstract

Purpose

The purpose of this paper was to examine the rheological characterisation of thickened water under different temperature and pH conditions and thickened milk with different fat contents.

Design/methodology/approach

Beverages thickened with powdered thickeners are used in the medical management of individuals who suffer swallowing difficulties (dysphagia). Each individual requires a specific level of thickness to best meet the needs of their dysphagia. Although the level of thickness is defined, obtaining the correct consistency of thickened fluids is difficult. This is due to fluctuations associated with temperature and type of fluids to be thickened. Rheological characterisation of commercially available xanthan gum-based thickener was performed under different conditions of temperature, pH and fat contents.

Findings

The viscosity and the yield stress of thickened water was found to be unaffected by pH. Similarly, temperature did not affect the viscosity at a high thickener concentration, although it did at lower concentration levels. Conversely, viscosity and yield stress increased as fat levels increased in thickened milk. Furthermore, thickened water took less than 2 minutes to reach equilibrium viscosity, while thickened milk required approximately 15 minutes to reach equilibrium viscosity.

Practical implications

These findings have implications for the standing time required for different beverages before they are thickened to a consistency that has been deemed safe for the patient’s physiological needs. Additionally, it highlights that different liquid base substances required different amounts of thickener to achieve the same level of thickness.

Originality/value

Findings from this study confirms and explores the variability of thickened fluids under different conditions of temperature, pH and fat content for the medical management of dysphagia.

Abstract

It would be difficult to find, especially during the summer months, a more popular confection than “ices,” or one which, when properly made, is more harmless or wholesome. They are universally liked by the young and old of all classes everywhere, and are in demand on all and every occasion. The volume of trade done in this commodity from the barrows of itinerant street vendors and from confectioners' shops is enormous. The process of manufacture is comparatively simple and in a small way requires little outlay for appliances or materials, consequently it appeals to the vendor with little capital, and the sales generally provide a fair margin of profit. Competition in the trade is keen. The price of the article is as low as can be consistent with the use of sound ingredients, and the desire to maintain profits has caused the cheapest possible materials to be used for the manufacture, resulting in many different qualities being sold. The general descriptions of the goods very rarely convey much information as to the nature of the materials used in their composition. An inspection of the labels displayed on vendors' barrows and in shops indicates that there are ices, ice‐creams, cream‐ices and creamy‐ices, the names being sometimes enriched with a qualifying description suggesting the addition of some flavouring agent. The names appear to be very loosely and irregularly applied to a variety of frozen products which may vary from sweetened water to sweetened cream, with many intermediate qualities. A search amongst the standard recipes for making ices discloses the fact that most of them are frozen custards which should be made from sweetened milk thickened with starch or eggs, with or without the addition of cream. The idea conveyed to the more intelligent and discriminating consumer when the term “cream” forms part of the description is that a certain proportion of that substance is employed in the composition of the ices, but there are others who are indifferent to the quality or composition so long as the product is ice‐cold, sweet and palatable. If made without cream they are masquerading under false names as “ice‐creams” or “cream‐ices,” and to be correct should be termed plain “ices.” Unfortunately this is only one case amongst many in this country where legal standards are necessary but lacking. When a vendor sells as “ice‐cream” something devoid of cream he commits an offence which should be treated in the same manner as other forms of adulteration. The American Government require ice‐cream to contain not less than 14 per cent. of milk‐fat, and the Canadian Government require a standard of not less than 7 per cent. of milk‐fat. In samples recently examined by the writer and submitted as “ice‐cream,” the fat varied from 1·5 to 7·5 per cent., and in only one instance could it be definitely shown that cream was present. The others were made from milk, and the fat varied with the proportion of milk present. If proceedings had been instituted under the Sale of Food and Drugs Acts in some of these cases it is doubtful if convictions could have been obtained, and failing conviction it would have probably been costly for the local authority concerned.

Abstract

Differences in laws and regulations concerning the basic materials, optional ingredients and food additives authorised in yogurt manufacture in each EC member state were studied. Not many differences exist regarding the basic materials. However, considerable differences exist with respect to optional ingredients and food additives. Legal provisions for different yogurt types and other requirements were also studied.

Abstract

Purpose

Member-owned business organizations, such as cooperatives, are engaged in various economic activities that touch our everyday lives. Sitajakhala Dugdha Utpadak Samabai Samiti Limited (Sitajakhala Dairy Producers Cooperative Society Limited) is a successful cooperative society in the northeastern region of India. The purpose of this case study is to illustrate how the cooperative manages its production and supply chain of milk and milk products and highlights several issues that the cooperative encountered in the recent past and how those issues were managed. This case also illustrates how an agribusiness cooperative has been growing over the years, including expansion of business and the creation of a brand image, as well as benefiting its members and their communities.

Design/methodology/approach

The authors used a case study approach where they went for in-person interviews of Sitajakhala's executive members and office staff; in addition, the authors were given access to Sitajakhala's marketing and financial records as well as its annual reports and vision documents.

Findings

Sitajakhala Co-op provides a platform where individual dairy farmers (most of who are small farmers and many of them are illiterate) can unite to bargain for higher prices for their milk. Due to its member-oriented business strategy, Sitajakhala Co-op has been growing well with active support of its members. Consistent quality control and marked improvements in labeling, bottling and packaging of milk and milk products has helped the cooperative to establish itself as a leader in dairy products supplier in Assam among bulk buyers as well as individual consumers. Sitajakhala cooperative also provides dairy farming related services to its members for free of charge to improve milk production and quality. One of the shortcomings of the cooperative is underutilization of its modern milk processing plant which needs to be addressed by the management in earnest.

Research limitations/implications

This case study is based on information from one dairy cooperative in Assam, India; thus, the findings of this case may not translate into other dairy cooperatives in India or elsewhere. Nonetheless, cooperative practitioners may find the findings useful from a management perspective.

Social implications

Sitajakhala Co-op management was keenly aware of the non-dairy related needs of the community it serves. Some of such services include free medical ambulance service for its members, supporting secondary education through providing merit and need-based scholarships and funding physical improvements to a local high school and a local college. In addition, the cooperative regularly provides funding to local sports and cultural events and local social institutions which have positive impact on the larger community. Sitajakhala cooperative has been providing employment to the local youth in the Morigaon area and plans on continuing to do so.

Originality/value

To the best of our knowledge, this is the first case study focusing on the management and operations of a dairy cooperative in the northeastern part of India. Knowledge gained from such study is expected to benefit not only Sitajakhala cooperative but also other dairy cooperatives in a similar situation. This case study will also benefit senior undergraduate and/or graduate students specializing in agricultural economics/agribusiness and can also be used for executive training for the management of academic institutions and food companies.

Abstract

Less than half a century ago almost the entire population of the United States lived upon food that was home‐grown and home‐prepared. With the exception of a few articles requiring a different climate than our own for their production, such as coffee, tea, sugar, spices, and chocolate, the inhabitants of the country lived exclusively upon food of their own producing, while the dealers of the city were supplied with the products of the neighbouring farms. Provisions of all kinds were supplied in an unprepared condition, and their preservation or preparation for the table was accomplished at the home.

Abstract

In those frightening years between the two Wars and governments in France came and went with dismal frequency, it used to be said that any French Government which permitted food prices to rise had no chance whatever of surviving, and the result was that food was bountiful and incredibly cheap. Times have changed dramatically but not the attitude of people to the price and availibility of food and, in particular of political control; this is very much the same as always. Mostly, it revolves around the woman and what she sees as an abuse, greed and taking mean advantage of prevailing conditions and, make no mistake, this will be reflected in the political field; in the way she votes. It has happened in previous elections; it will happen in even greater degree in the next election and, although not decisive, it can have a not insignificant impact. None know better than the housewife how meaningless is the smug talk of the politicians when it comes to food prices. Their attitude may not have been the main factor in throwing out the last Conservative Government; this was undoubtedly the fear that their continuance in office would result in widespread strikes and the serious effect these upheavals have on food prices (and other household necessit ies), but the votes of woman were an unimportant contribution. As it was, it mattered little to the muscle men of the trade unions which party is in power. Women's talk around the shops and supermarket's, up and down the High Street to‐day is one long grumble and disillusionment with politicians generally.

Abstract

The thirteenth annual report of the Ministry of Health, 1931–1932 (H.M. Stationery Office, price 5s. net), states that during the year the appointments of 23 Public Analysts were approved. The number of samples of food and drugs submitted to Public Analysts in the year 1931 was 136,169. This was a decrease of 346 as compared with the number for the previous year, which was the highest recorded; 6,324 samples were reported as adulterated or not up to standard, being 4·6 per cent. of the number examined. This is the lowest percentage recorded and compares with 4·8 per cent. in 1930 and 5·4 per cent. in 1929. The detailed statement in regard to the samples analysed is as follows:—
