Institute is residual when the whey of present embodiment refers to such as removing fat, casein, liposoluble vitamin from cow's milk The water soluble ingredient stayed.Whey is typically the cheese breast obtained as by-product when manufacturing natural cheese or enzyme coagulates casein Clear or enzyme curdled milk clear (or also referred to sweet whey), whens by skimmed milk manufacture acid casein, acidified milk or quark cheese etc. and Casein whey, acid whey, the quark cheese whey of acquisition.Lactalbumin refers to the egg in addition to casein for example in cow's milk White general name.Lactalbumin is made of Multiple components such as beta lactoglobulin, α-lactalbumin, lactoferrins, does not include lactose, dimension Raw element, minerals etc..When the dairy milk starting material of cow's milk etc. is adjusted to acidity, the albumen of precipitation is casein, unprecipitated albumen It is lactalbumin.
It should be noted that the whey of present embodiment also includes:By whey carry out concentration obtained by condensed whey, The whey powder of processing gained is dried, by ultrafiltration (Ultrafiltration in whey:UF) method etc. is by the main of whey Whey protein concentrate (the Whey Protein for handling gained are dried after carrying out concentration in albumen etc. again Concentrate:Be also referred to below " WPC "), by microfiltration (Microfiltration:MF) method or centrifugal separation etc. will Degreasing WPC (the high eggs of low fat obtained by handling are dried again after carrying out concentration using UF methods after whey removal fat In vain), after major protein of whey etc. selectively being carried out fractionation processing using ion-exchange-resin process or gel filtration etc. Lactalbumin isolate (the Whey Protein Isolate of processing gained are dried again:Be also referred to below " WPI "), utilize Nanofiltration (Nanofiltration:NF) the de- of processing gained is dried after carrying out desalting processing in method or electrodialysis method etc. again Salt whey is carried out using centrifugal separation etc. obtained by concentration after the mineral composition from whey to be carried out to precipitation process Minerals condensed whey etc..
The whey peptides of present embodiment are such as can manufacture the hydrolysis with enzyme below of whey or lactalbumin.For The enzyme of whey hydrolysis is pepsin, trypsase and chymotrypsin, but also have using plant-derived papain, Protease from bacterium or mushroom research report (Food Technol., 48:68-71,1994;Trends Food Sci. Technol., 7:120-125,1996;Food Proteins and Their Applications, the 443-472 pages, 1997).The enzymatic activity of hydrolyzing lactoalbumin can dramatically change.Pepsin decomposing alpha-La and α-the La being denaturalized, but do not decompose Unmodified (natural) β-Lg (Neth. Milk dairy J., 47:15-22,1993).Although trypsase can slow water Solve α-La, but β-Lg almost keep undecomposed state (Neth. Milk dairy J., 45:225-240,1991).Pancreas is solidifying Although galactase fast decoupled α-La, β-Lg are slowly decomposed.Although papain hydrolyzes bovine serum albumin(BSA) (BSA) With β-Lg, but α-La have repellence (Int. Dairy Journal 6:13-31,1996a).However, α-the La of unbonded Ca Can completely be decomposed by papain at acidic (J. Dairy Sci., 76:311-320,1993).
The hydrolysis of peptide bond can cause charged group number and it is hydrophobic increase, the spatial configuration of low molecule quantization and molecule Modification (J. Dairy Sci., 76:311-320,1993).The variation of its functional characteristic depends greatly on hydrolysis Degree.Common visible maximum variation is the reduction of deliquescent increase and viscosity in the functionality of lactalbumin.Degree of hydrolysis is high Situation, hydrolysate will not precipitate heating for multiple times, and in pH3.5~4.2, lower dissolubility is high.The viscosity of hydrolysate is far below (intact) albumen that do not dispose.This difference is particularly significant in the highly concentrated situation of albumen.Other influences are the change of gel characteristic Change, improve the reduction of the emulsification of thermal stability and enhancing, the emulsification and bubble stability of foaming characteristic.
The whey peptides used in present embodiment preferably have anti-inflammatory effect.LPS is inhibited to lure in vivo for example, confirming it The effect that the property led TNF-α and IL-6 are generated.Whether have the function of that LPS inductivities TNF-α and IL-6 is inhibited to generate, can pass through Well known measurement system (such as experimental medicine fascicle, " biological handbook UP experimentalists and technicians ", cell factor experimental method, palace island are sincere, mountain This refined Knitting, (strain) Yang Tushe, 1997) confirm.Using LPS inductivities TNF-α and/or the inhibition of IL-6 generations as index, Above-mentioned document (International Dairy Journal 12 can be referred to:813-820,2002) it tries to carry out lactalbumin Hydrolysising condition (denaturation temperature, pH, temperature, hydrolysis time and enzyme/substrate ratio) optimization.It should be noted that this reality It applies the whey peptides used in mode and includes the holding liquid or permeate (permeate) after whey peptides itself, ultrafiltration membrane treatment.
