Effects of transglutaminase (TGase) treatment on properties of cast films from soy protein isolates (SPI-1, SPI-2), sodium caseinate (NaCas-1, NaCas-2) and gelatin (G-1, G-2) were investigated.
The catalytic characteristics of MTGase (Microbial Transglutaminase) against two-substrate proteins, including β-lactoglobulin (β-LG)/sodium caseinate (SC), bovine serum albumin (BSA)/β-LG, BSA/SC, glycinin/β-LG, glycinin/SC andglycinin/BSA systems were studied by SDS-PAGE.
The effects of transglutaminase(TGase)treatment on the properties of edible films cast from soybean protein isolates(SPI1,SPI2),sodium caseinate(NaCN1,NaCN2)and gelatin(G1,G2)were investigated.
The influence of TGase treatment on the properties of the cast films from several food proteins including soy protein isolates (SPI-1, SPI-2), sodium caseinate (NaCas-1, NaCas-2), whey protein concentrate (WPC), gelatin (G-1, G-2), wheat gluten (WG) and peanut protein isolate (PPI) were investigated in this dissertation.
Results show that conjugates with R=3:1 reacted at 79% RH for 7 days have excellent emulsifying activity, and their emulsifying activity and stability are close to those of sodium caseinate at pH7.0 and 4.0. The emulsifying stability of the conjugates at the ionic strength of 0.2 mol/L NaCl is higher than that of sodium caseinate, but the emulsifying activity is far lower than that of soy protein isolates.
A powder of ready to drink of carrot juice was prepared by adding 15% of corn oil, 3% of emulsifiers, 3% of sodium caseinate and 40% of maltodextrin into enzymatic prepared carrot juice using micro-encapsulation and spray drying techniques.
This study got clear the isoelectric point and heat resistance of Protein in wild badam kernel; kernel/water ratio 1: 15 ~ 20, steeping temperature 20 ~ 25℃, steeping time 22 ~ 26 hours and the stablizer groups (Sucrose Fatty Acid Ester 2. 5g, PGA 3. 5g, CMCNa 1. 1g, Sodium Caseinate 7. 0g) are the best technics parameters processed the protein beverage of wild badam kernel.
Used as emulsifier,stabilizer and fine protein resource,cooperated with sodium alginate and monoglyceride,sodium caseinate can keep the product stable without oil separation within 24h.
It showed that sodium caseinate and BSA were the best substrates of MTGase, and glycininfollowed next, andβ-conglycinin and whey proteins were poor substrates of MTGase.
Tween-stabilized emulsions oxidized faster as pH increased from 3 to 7, whereas a different behavior was observed in emulsions stabilized with sodium caseinate or a mixture of both emulsifiers.
In most cases, sugar crystallization-studied by water sorption behavior, x-ray diffraction, and non-isothermal calorimetry-occurred significantly slower in systems containing Na-caseinate compared to MPC.
Combined injections of sodium caseinate and phenobollne, the stimulant of protein synthesis, resulted in the development of more intensive morphological and functional manifestations of amyloidosis in old rats.
Sodium caseinate is the main protein in milk. Sodium caseinate can be obtained by treating casein separated by acidifying skim milk to a pH of about 4.6 with NaOH、 Na_2CO_3 or NaHCO_3. This present paper gives an introduction to the results of our research on preparation of it.
The viscosity behavior of sodium caseinate was accessed within the range of total solid 12%  ̄20% and temperature 65 ̄ 90℃. The effect of pH on the viscosity was not significant within the range of 6. 8 ̄ 7. 5. The viscosity logrithums were linear with temperatures and total solids (R2>95%).Quadratic equations were significantly fitted for the relationships between (1) the temperature and the equation slops for viscosity and solid (R2=91. 41 % );(2)the temperature and the equation intercepts for the visc...
In this paper,an analysis was conducted concerning scanning electron photomicrograph of the sausage sample of sodium caseinate added,with the latter being formed about 1 μm indomitable hydrophilous protein film on the surface of the fat globule in increasing stability of fat,protein and water system.
