Flavors solubility-limiting methods

FLAVOR MODIFICATION TECHNOLOGIES Solubility-Limiting Methods... [Pg.1770]

During isolation by conventional methods yeast proteins frequently become denatured, insolubilized and display poor functional properties. These proteins can be rendered more soluble by limited hydrolysis with acid, alkali or proteolytic enzymes. Protein hydrolyzates are most commonly prepared by partial acid hydrolysis and yeast hydrolyzates are popular as food flavorings and ingredients (66). Acid hydrolyzates have flavors resembling cooked meats and are widely used by earners to impart brothy, meaty flavors to soups, gravies, sauces, canned meats. [Pg.55]

Food proteins, especially those of plant origin, often require modification to achieve desirable functional properties for use as food ingredients. For instance, soy protein has limited water solubility at acid pH, which restricts its use in acidic foods such as coffee whitener and acidic beverages. Improved solubility at acid pH for commercial soy protein isolate can generally be achieved by hydrolysis. However, the hydrolysis has to be carefully controlled, because excessive peptide bond hydrolysis may release bitter peptides, resulting in undesirable off-flavors. Scientists are constantly looking for better and safer methods to improve the functional properties of protein to meet the needs of the food industry. [Pg.91]
