Download or read book The Use of Certain Microbial Inhibitors to Increase the Keeping Quality of Cottage Cheese written by Ellen Fen-Lan Huang and published by . This book was released on 1969 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cottage cheese is a nutritious food, but a highly perishable product because it provides an excellent medium for the growth of many microorganisms introduced during its manufacture. It has a normal shelf life of 10 to 14 days at refrigeration temperatures in the market. However, occasionally the shelf life of the product is less than expected and this reduction is thought generally to be due to lapses in refrigeration during distribution or after purchase by the consumer. This study investigated the effects of exposure periods of as long as 8 hours at room temperature on the storage life of cottage cheese with and without microbial inhibitors. The results showed significantly different effects for different inhibitors. Aureomycin and vitamin K,- had little effect, sodium propionate had somewhat more effect and potassium sorbate had the greatest effect in extending the storage life of cottage cheese. Cottage cheese exposed to room temperature had a longer shelf life when the remainder of its storage was at 2°C than when it was at 5° or 8°C. Cottage cheese subjected to various room temperatures (i.e. 20-29°C) for periods of 4, 6 and 8 hours showed that the subsequent storage life varied inversely with the period of exposure.

Available in PDF, EPUB and Kindle. Book excerpt: The second edition of Basic Food Microbiology follows the same general outline as the highly successful first edition. The text has been revised and updated to include as much as possible of the large body of infor mation published since the first edition appeared. Hence, foodborne ill ness now includes listeriosis as well as expanded information about Campylobacter jejuni. Among the suggestions for altering the text was to include flow sheets for food processes. The production of dairy products and beer is now depicted with flow diagrams. In 1954, Herrington made the following statement regarding a review article about lipase that he published in thejournal of Dairy Science: "Some may feel that too much has been omitted; an equal number may feel that too much has been included. So be it." The author is grateful to his family for allowing him to spend the time required for composing this text. He is especially indebted to his partner, Sally, who gave assistance in typing, editing, and proofreading the manuscript. The author also thanks all of those people who allowed the use of their information in the text, tables, and figures. Without this aid, the book would not have been possible. 1 General Aspects of Food BASIC NEEDS Our basic needs include air that contains an adequate amount of oxy· gen, water that is potable, edible food, and shelter. Food provides us with a source of energy needed for work and for various chemical reactions.

Download or read book Microorganisms in Foods 5 written by International Commission on Microbiological Specifications for Foods and published by Springer Science & Business Media. This book was released on 1996-06-30 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to assemble detailed information relating to foodborne pathogens in order to make it readily accessible to those who wish to employ the HACCP system for the control of microbial hazards. The book is concerned solely with foodborne pathogens and does not discuss spoilage organisms. Each chapter provides a general survey of a foodborne pathogen, with appropriate referencing to authoritative review material. Reviews the history and the occurrence of the organism in nature as well as its taxonomy. Discusses the symptoms (but not the treatment) of the relevant foodborne disease syndrome(s), as well as the mechanism of pathogenicity. Consideration is given to the available method for the enumeration and identification of the organism, as well as possible alternative methods. Also reviews the epidemiology of the foodborne disease and its importance. Each chapter concerns itself with the specific parameters that influence the growth, survival or death of the microorganism. Includes information on temperature, water activity, pH, irradiation, preservatives, gases, disinfectants and, where possible, on interactions between these parameters. Written for food technologists, product developers, food microbiologists and regulators.
Download or read book Microbiological Physico chemical and Sensory Quality Aspects of Dairy Desserts Manufactured from Cottage Cheese written by Jane Motladi Boikhutso and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Two novel strawberry cottage cheese desserts were developed in this study and evaluated regarding their microbiological, physico-chemical and sensory characteristics. The purpose of the study was to develop cottage cheese desserts, both full-fat (FFCCD) and skim milk (SMCCD) from fresh cottage cheese. Four formulations were made by adding fruit pulp to the cottage cheese. These were: treatment 1 = 0 % fruit pulp, treatment 2 = 10 % fruit pulp, treatment 3 = 20 % fruit pulp and treatment 4 = 30 % fruit pulp. All of the four treatments were found to be acceptable by a consumer panel and preference scale increased with an increase in the percentage fruit pulp added, texture and appearance. The microbiological status of the treatments was also at acceptable levels at the proposed shelf life of 21 days after which, spoilage microorganisms started to grow. The added fruit pulp increased their keeping quality by increasing the shelf life. The composition of the two desserts types was also acceptable and compared well with results from other studies. It still remains that the fat content played a major role in distinguishing the two dessert types. The effect of the fat, fruit and fat/fruit interaction was evaluated. During shelf life studies, the effect of the fat, fruit, fat/fruit, day, day/fat, day/fruit as well as the day/fat/fruit interaction was also evaluated on the microbiological, pH and titratable acidity values of the treatments with a tendency to decrease by day with an increase in the percentage fruit added. It could then be concluded that the addition of fruit pulp to the fresh cottage cheese increased its shelf life, acceptability and the new product serves as an alternative to fruit blended yogurts which exist in the market. The methods used could be adapted to a small scale and thus be part of food security programmes in South Africa. However, for the new product to partake in the dairy industry, it is recommended that the product be marketed properly.

This book was released on 2012-12-12 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Predictive microbiology is a recent area within food microbiology, which studies the responses of microorganisms in foods to environmental factors (e.g., temperature, pH) through mathematical functions. These functions enable scientists to predict the behavior of pathogens and spoilage microorganisms under different combinations of factors. The main goal of predictive models in food science is to assure both food safety and food quality. Predictive models in foods have developed significantly in the last 20 years due to the emergence of powerful computational resources and sophisticated statistical packages. This book presents the concepts, models, most significant advances, and future trends in predictive microbiology. It will discuss the history and basic concepts of predictive microbiology. The most frequently used models will be explained, and the most significant software and databases (e.g., Combase, Sym’Previus) will be reviewed. Quantitative Risk Assessment, which uses predictive modeling to account for the transmission of foodborne pathogens across the food chain, will also be covered.
