Abstract:
La presenté invención se refiere a un método para la obtención de un alimento deshidratado con un alto contenido de proteínas hidrolizadas a partir de agua de cola de pescado; para esto, sé separan los sólidos insolubles y las trazas de grasa del agua de cola, la misma que es a continuación sometida a un proceso de desmineralización mediante electrodiálisis, para luego acondicionar su temperatura y pH a fin de proceder con la hidrólisis enzimática, que permite fraccionar la proteína, la cual es posteriormente concentrada y secada por atomización en un deshidratador tipo spray dryer, siendo finalmente el producto seco convenientemente envasado.
Abstract:
Methods for modifying a non-dairy protein ingredient to improve its performance in a liquid nutritional composition involve increasing the solubility of the protein ingredient such that a value R is greater than 10, where R is the ratio of a percent of the protein soluble in water to a degree of hydrolysis (DH) of the protein.
Abstract:
Provided herein are methods of making emulsions comprising triglycerides and a marine peptides wherein the method is carried out in the substantial absence of an added emulsifier.
Abstract:
The present invention relates to a novel process for the isolation of unique anti-oxidative glycoproteins from the pH precipitated fractions of enzymatic extracts of brown algae. Two brown seaweeds viz, Fucus serratus and Fucus vesiculosus were hydrolysed by using 3 enzymes viz, Alcalase, Viscozyme and Termamyl and the glycoproteins were isolated from these enzyme extracts.
Abstract:
The present invention relates to a protein hydrolysate, wherein the hydrolysate has a percentage of peptides having a histidine residue at the C-terminal end of at least 10 wt% of the total peptide content of the protein hydrolysate and a process for preparing the protein hydrolysate. The invention further relates to a food or feed product comprising the protein hydrolysate.
Abstract:
The present invention contemplates the creation of a low fluoride crustacean oil processed from a phospholipid-protein complex (PPC) formed immediately upon a crustacean (i.e., for example, krill) catch. Further, the crustacean oil may also have reduced trimethyl amine and/or trimethyl amino oxide content. The process comprises disintegrating the crustaceans into smaller particles, adding water, heating the result, adding enzyme(s) to hydrolyze the disintegrated material, deactivating the enzyme(s), removing solids from the enzymatically processed material to reduce fluoride content of the material, separating and drying the PPC material. Then, using extraction with supercritical C02 or supercritical dimethyl ether, and/or ethanol as solvents, krill oil, inter alia, is separated from the PPC. In the extraction the krill oil can be separated almost wholly from the feed material.
Abstract:
A rice protein hydrolysate obtainable by a process in which a rice protein source is enzymatically hydrolyzed with an enzyme with endoprotease and/or exoprotease activity, and let it act under constant temperature and pH. The rice protein hydrolyzate is useful in the treatment and prevention of obesity. The invention also relates to edible compositions, nutritional compositions and pharmaceutical compositions including the rice protein hydrolysates.
Abstract:
The present invention relates to polypeptides having endopeptidase activity and to methods of producing and using the polypeptides. The invention also relates to methods of making a food protein hydrolysate using a trypsin-like endopeptidase derived from a bacterium.
Abstract:
Described herein are methods of identifying and releasing bioactive peptides from ovotransferrin The method involves (a) contacting ovotransferrin with a reducing agent, a sonication step, a high pressure processing step, a heating step, a fermentation step, or any combination thereof, and (b) contacting the ovotransferrin after step (a) with a hydrolytic enzyme to produce bioactive peptides that exhibit angiotensin converting enzyme inhibitory activity or antioxidant activity when compared to the parent protein. The bioactive peptides may be added to foodstuffs, a medication, or to any potable, ingestible, or edible compositions.
Abstract:
The present invention relates to a process to purify enzymatically digested heparin-derived protein hydrolysate (peptone) comprising the step of passing the peptone through a nanofilter at a temperature of about ambient to about 130°F and a pressure of about ambient to about 360 psi resulting in peptone concentrate.
