Available in PDF, EPUB and Kindle. Book excerpt: Thermobacteriology in Food Processing, Second Edition focuses on the principles involved in sterilization processes for canned goods and pasteurization of foods. The book first ponders on organisms of greatest importance in the spoilage of canned foods and food pasteurization and bacteriological examination of spoiled canned foods. Discussions focus on toxin-producing microorganisms, pathogenic microorganisms, bacteriological examination, classification of spore-bearing bacteria with reference to oxygen requirements, classification of food with respect to acidity, and interpretation of observations. The text then takes a look at contamination and its control, producing, harvesting, and cleaning spores for thermal resistance determinations, and death of bacteria subjected to moist heat. The manuscript tackles thermal resistance of bacteria and thermal process evaluation, including important terms and equations, basic considerations, general method, and conversion of heat penetration data. Topics include change of initial food temperature when the retort temperature remains the same, integrated lethality of heat at all points in the container, heat penetration and processing parameters, and determination of process lethality requirement. The publication is a valuable reference for researchers interested in thermobacteriology in food processing.

Download or read book Characterisation of the Mechanical Properties of Heat Induced Protein Deposits in Immersed Cleaning Systems written by Jintian Liu and published by Springer Nature. This book was released on 2023-01-02 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: During heat treatment in dairy production, the rapid formation of heat-induced fouling deposits on the plant surface leads to reduced efficiency of heat transfer. Therefore, a regular cleaning process is required to soften the heat-induced protein deposits and then remove them from the plant surface. The mechanical property of the deposits is one of the key issues of the cleaning mechanisms since the non-fractured behaviour dominates the deformation of the fouling layer and the failure behaviour has a great impact on the cohesive removal of fouling deposits. Considering the complicated geometry of fouling deposits and their irregular distribution, indentation experiments were carried out on various kinds of protein deposits. The experimental results reveal the significant influence of the thickness of fouling deposits on their mechanical behaviour and the time-dependent nonlinear behaviour of the deposits. Furthermore, heat-induced whey protein gel was used as the model material for fouling deposits and the non-fractured and fracture behaviour was characterized using compression and wire cutting experiments, respectively. The material parameters identified using the inverse finite element method allow the prediction of fracture behaviour under localized external loads and provide a deeper insight into cohesive removal. To investigate the softening effect during caustic washing, tensile experiments were conducted on chemically treated and untreated whey protein gels. Adequate chemical degradation leads to a softer mechanical response and increased stress relaxation, making whey protein gels more flowable and more resistant to tensile deformation. The experimental results provide useful data on the failure behaviour of chemically treated whey protein gels.

Book excerpt: The enzymology of milk and other products is of enormous significance for the production and quality of almost every dairy product. Milk itself is a complex biological fluid that contains a wide range of enzymes with diverse activities, some of which have identifiable functions while others are present as an accidental consequence of the mechanism of milk secretion. Over time milk enzymology has become an incredibly essential component of milk and other dairy product production, and with advancing technology and processing techniques, its importance is at its peak. Dairy Enzymology presents an expansive overview of the enzymology of milk and other dairy products, focusing on the use of indigenous and endogenous enzymes in milk and exogenous enzymes in cheese processing. A full section is dedicated to the enzymology of bovine milk, focusing on the main families of indigenous enzymes as well as their potential significance in the mammary gland plus the technological significance for the properties of dairy products. Implications for the manufacture and ripening of cheese plus the use of enzymes such as alkaline phosphatase for measuring heat treatment in milk are explored in full, and the role of milk protease plasmin and other indigenous enzymes in the age-gelation is focused on. Further sections focus on enzymes found in raw milk and enzymes deliberately added for manufacture or modification of properties and the manufacture of food ingredients from dairy-derived ingredients. The key bacterial families are discussed in depth as well as their known contributions to the quality of dairy products. With its comprehensive scope and fully up-to-date coverage of dairy product enzymology, this text is a singular source for researchers looking to understand this essential dairy processing aspect.
