摘要:
Thermostable lactase produced by growth of thermophilic fungi, harvesting resulting mycelium, separating lactase from mycelium by radical rupture of cell structure or by subjecting cell structure to milder treatment which does not separate lactase from the structure, and separating cell debris. Resulting lactase has high degree of activity and is thermostable such that it can be used at relatively high temperatures, e.g. 60.degree. C., and at acid pH to catalyze hydrolysis of lactose to glucose and galactose.
摘要:
Processes for the production of essentially solid nutriments and fodders containing a high content of proteins by the cultivation of a yeast on a liquid culture medium consisting of whey containing at least a substantial portion of its original soluble proteins and thereafter separating from the resulting brew the solids consisting of yeast cells and the original soluble proteins or products of the original soluble proteins by means of an ultrafilter provided with one or more membranes that are essentially impervious to soluble proteins and subsequently drying the said solids.The preliminary separation of the soluble proteins from the whey by centrifugal separation or by ultrafiltration, as described in the prior art, is avoided. In such prior ultrafiltration processes, the membranes of the ultrafilter become clogged with the soluble proteins, thereby retarding and ultimately stopping the filtration. The brew that is produced in accordance with the processes of the present invention which contains yeast cells together with the original soluble proteins or products thereof can be separated in an ultrafilter at a faster rate than the soluble proteins could have been preliminarily separated from the whey and the ultrafilter membranes do not become clogged with the solids that are thus separated.
摘要:
Aqueous solutions containing dissolved cheese whey protein exhibiting improved whipping properties are obtained by heating the solution to within the range of at least 90.degree. C. to less than 99.degree. C., thereafter cooling the solution to less than 60.degree. C., and whipping the solution within about 8 hours after heating. The process is particularly effective with protein solutions derived from cheese whey protein concentrates.

Modified dried whey derived by the molecular sieve fractionation of partially delactosed cheese whey mother liquid enhances flavor in foods and improves binding, flavor enhancement, and emulsification in comminuted meat products.
摘要:
A method for forming a substitute for nonfat milk in such uses as a dough additive for baked products. The method includes the treatment of aqueous whey, preferably in concentrate form, with calcium hydroxide to form a whey buffer complex capable of controlled release of dissociated calcium ions. Thereafter, casein is added to react with the calcium and form a stable dispersion of calcium caseinate throughout the whey and to form a complex product. This complex may be further reacted with sodium phosphate to form another product with calcium phosphate bridges in the complex. Either product may be dry blended with sodium caseinate to increase the overall protein content, if desired for a particular function as a nonfat milk substitute.
摘要:
BEVERAGE MIX CONTAINING SWEETENER, COLOR, FLAVOR, FOOD ACID, AND ALL THE SOURCE OF PROTEIN, EGG ALBUMEN AND WHEY. THE SHEY CONSTITUTES FROM ABOUT 20% TO ABOUT 50% OF THE PROTEIN OF THE ALBUMEN AND WHEY MIXTURE AND INHIBITS THE TASTE AND ODOR OF THE EGG ALBUMEN IN THE FINAL BEVERAGE.
摘要:
THE OBJECTABLE ODORS AND TASTE OF WHEY ARE REMOVED THEREFROM AND A BLAND WHEY PRODUCT IS PRODUCED BY GROWING YEASTS IN A FLUID WHEY SYSTEM CONTAINING AT LEAST 10 P.P.M. OF DISSOLVED OXYGEN TO SUBSTANTIALLY PREVENT FERMENTATION AND PROVIDE ASSIMILATION.
摘要:
A process for isolating from an aqueous solution in their natural form proteins of the class of albumin, globulin and mixtures thereof which includes raising the pH of the aqueous protein solution to at least 8.5 and then flocculating the protein at its iso-electric point.
