Yeasts are the active agents responsible for three of our most important foods - bread, wine, and beer - and for the almost universally used mind/ personality-altering drug, ethanol. Anthropologists have suggested that it was the production of ethanol that motivated primitive people to settle down and become farmers. The Earth is thought to be about 4. 5 billion years old. Fossil microorganisms have been found in Earth rock 3. 3 to 3. 5 billion years old. Microbes have been on Earth for that length of time carrying out their principal task of recycling organic matter as they still do today. Yeasts have most likely been on Earth for at least 2 billion years before humans arrived, and they pla...
In the past 35 years, the use of commercial enzymes has grown from an insignificant role in the food industry to an important aspect of food processing. This Third Edition of Enzymes in Food Processing explores recent and extensive changes in the use of enzymes as well as the discovery of new enzymes and their uses. Included in the book is a history of the role of enzymes in food processing, enzyme characterization, a discussion of different classes of enzymes including lipases and proteases, commercial enzyme production, and the processing of particular foods such as meat, vegetables, fruit, baked goods, milk products, and beer. Unlike earlier editions, it provides basic information on enzy...
Protein hydrolysates, otherwise commonly known as peptones or peptides, are used in a wide variety of products in fermentation and biotechnology industries. The term “peptone” was first introduced in 1880 by Nagelli for growing bacterial cultures. However, later it was discovered that peptones derived from the partial digestion of proteins would furnish organic nitrogen in readily available form. Ever since, p- tones, which are commonly known as protein hydrolysates, have been used not only for growth of microbial cultures, but also as nitrogen source in commercial fermen- tions using animal cells and recombinant microorganisms for the production of value added products such as therapeut...
Contributors from universities and food, pharmaceutical, and brewing companies detail the current state of yeast strain development and handling, highlighting advances in yeast selection for academic research, industry, and recombinant DNA technology. Featuring the use of Saccharomyces and other yea
This volume supplements the other books on this subject by providing much information that is not readily available elsewhere. It opens with a taxonomy of fungi in foods and feeds and then considers ecology, spoilage, and mycotoxin production by fungi in foods and feeds. This is followed by a series
This work offers comprehensive, authoritative coverage of current information on indigenous fermented foods of the world, classifying fermentation according to type. This edition provides both new and expanded data on the antiquity and role of fermented foods in human life, fermentations involving an alkaline reaction, tempe and meat substitutes, amazake and kombucha, and more.;College or university bookstores may order five or more copies at a special student price which is available on request from Marcel Dekker, Inc.
Since The Compleat Meadmakerwas first published, mead has continued to grow in popularity as crafted beverages have become an established part of the beverage market in America. In 2003 there were roughly 60 commercial meaderies in the US, but by 2020 this number stood at 450. Naturally, many hobbyists are also discovering the delights of making this “nectar of the gods” themselves. Thanks to the global distribution of bees and, therefore, honey, you will find mead-like drinks in virtually every corner of the world. No wonder historians recognize it as one of humankind’s oldest fermented beverages. Mead production never really ceased in Europe and Africa, but its star was eclipsed with...

The accelerated globalization of the food supply, coupled with toughening government standards, is putting global food production, distribution, and retail industries under a high-intensity spotlight. High publicity cases about foodborne illnesses over recent years have heightened public awareness of food safety issues, and momentum has been building to find new ways to detect and identify foodborne pathogens and eliminate food-related infections and intoxications. This extensively revised Third Edition covers how the incidence and impact of foodborne diseases is determined, foodborne intoxications with an introduction that notes common features among these diseases and control measures that are applicable before and after the basic foodstuff is harvested.* A summary of the foods most association with human infections* A discussion of the principles of laboratory detection of the agent considering the advantages and disadvantages of various procedure* A 'historical to present-day' section* A description of the infection in humans and animals, including reservoirs and the mode of transmission
Abstract: This publication is a detailed reference source which surveys the functions and applications of additives used in baked foods at relatively low levels. Written for a wide range of bakery professionals, the text explains how each class of additives functions and relates the action of each additive to the ultimate purpose of the baker-- making high-quality baked products. The additives discussed in this volume include oxidants, reductants, emulsifiers and surfactants, enzymes, chemical leavenings, yeast, vital wheat gluten, and gums.
