  • Patent number: 5082672
    Abstract: Deamidation of food proteins by Bacillus circulans peptidoglutaminase was impaired by the large molecular size and unique conformation of these proteins. The limited ability of peptidoglutaminase to deamidate food proteins was increased dramatically by protein hydrolysis and altering protein conformation, principally by moist heat. A method to prepare enzymatically deamidated food proteins with a wide range of protein deamidation was developed. Enzymatic deamidation of proteins improved their functional properties especially in the mild acidic pH region (e.g., 4-6).

  • Patent number: 5000967
    Abstract: An improved process for preparing individual fruit sections from fresh citrus fruit, with improved ease of peeling and sectioning and with reduced amounts of adhering albedo. The fresh citrus fruit are initially scored so as to penetrate the albedo layer, but not the underlying juice sections, and the scored fruit is then immersed in an aqueous solution of a pectinase enzyme. A series of positive pressure pulses is applied to the immersed fruit, to infuse the enzyme solution into the albedo and, after storing the infusion-treated fruit for a prescribed time period, the peel and other membrane material can be readily removed from the fruit and the individual fruit segments readily separated from each other. Infusing the pectinase enzyme solution under pressure, rather than vacuum, and maintaining the solution at approximately room temperature, rather than an elevated temperature, significantly improves the ease of peeling and sectioning and reduces the amount of adhering albedo.

  • Patent number: 4882180
    Abstract: A soybean hydrolyzate is disclosed. The hydrolyzate is of a high nutritional value and excellent in protein absorbability. Moreover, it is free from bean-like or grass-like smelling that is characteristic of soybean, as well as from bitter taste. Consequently, the hydrolyzate is very valuable food as protein source.The hydrolyzate is characterized by that the soluble fraction of the hydrolyzate contains amino nitrogen in an amount in the range from 5 to 20%, preferably from 10 to 15% of the total nitrogen of said fraction. The hydrolyzate is prepared by pulverizing soybean, adding water to the pulverized soybean to form a slurry of a solid content in the range from 1 to 20%, heating the slurry at a temperature from 60.degree. to 100.degree. C. for a period from 5 to 180 minutes, homogenizing the slurry under a high pressure and hydrolyzing the homogenates with a neutral protease produced by Bacillus subtilis.
