摘要:
The invention relates to a method for enzymatically obtaining protein hydrolysates for human consumption, animal feed and cosmetics. The process involves the use of a proteolytic composition derived from fish, such as Cod (Gadus morhua), to obtain hydrolysates which have a non-bitter taste and retain the flavor and aroma of the protein-containing material which is hydrolyzed: e.g. when hydrolyzing protein-containing material from marine organisms or parts thereof, such as fish, shrimp, lobster or other seafood according to the invention, a protein hydrolysate is produced that has a characteristic natural flavor of the organism Also provided are food products comprising the hydrolysates of the invention, such as soup, sauce, cheese, HVP, meat extract and flavoring agent, broth, paté, mousse, frying dough, orly dough, and pastries.
摘要:
A process for treating rice bran, preferably defatted rice bran, to produce a high value protein product and a cellulosic residue both from rice bran. The high value protein product is useful as a protein supplement or feed for livestock and poultry and the cellulosic residue has value as a feedstock for a thermochemical process unit for the production of a biofuel. The rice bran is subjected protein hydrolysis and a resulting liquid stream containing hydrolyzed proteins is sent through a two membrane filtration stages, the first being a microfiltration and the second being a nanofiltration stage.
摘要:
A five-step manufacturing method using broad spectrum hydrolytic enzymes to decompose the volatile fraction of organic waste materials into lower molecular weight, intermediate substrate nutrients to be consumed in turn by selected microorganisms to produce a cellular biomass of microbial cells subsequently harvested for use as a bio-protein feed supplement for farm and domestic animals. A wide range of agricultural, industrial and organic waste materials may be used as the input raw material resource for biochemical processing to bio-protein feed. Applied to the use of cattle manure slurry as raw materials, the biolytic decomposition step employs hydrolyzing enzymes to dismutate volatile organic insoluble high molecular weight proteins, starches, fats, and partially hydrolyzed cellulose compounds into soluble, low molecular weight nutrient intermediates in solution, from which the relatively stable cellulose-lignin solid by-product fraction is separated and dewatered. The Cellular Synthesis step uses selected microorganisms which metabolize and convert these nutrient intermediate products, plus oxygen and nitrogen from air, in their growth and proliferation into a biomass of microbial cells. The biomass is separated and utilized as a single cell bio-protein feed supplement for farm animals. The remaining liquid fraction, mainly water and relatively stable organic matter and mineral salts in solution, may be stored for subsequent irrigation and conditioning of agricultural lands and in the interim may be recirculated for feedlot flushing. The solids by-product, mainly cellulose and lignin, may be used as a fuel or biochemical feedstock or may be recombined with the liquid fraction during irrigation discharge to add mulch-fertilizer soil building values.
摘要:
The invention relates to the uses of a new characterized TET protein showed restricted to N-terminus glycine residues exopeptidase. The invention also relates to a method comprising said use of said new characterized TET protein as a N-terminus glycine residues specific exopeptidase. The invention further relates to a support wherein it is immobilized on said new characterized TET protein as a N-terminus glycine residues specific exopeptidase.
摘要:
A process for preparing a nutritional supplement includes the steps of mixing animal blood solids, hydrolized poultry feathers and animal offal to create a mixture, adding protease enzyme to the mixture (20), digesting the mixture with protease enzyme (28) and drying the digested mixture (38) in order to reduce the moisture content thereof down to 5-8 weight percent. During processing, the digested mixture is never exposed to temperatures above approximately 83° C. so that the blood and offal are not degraded or denatured and remain intact so as to provide full nutritional benefit.
