The use of whey protein concentrate (WPC) for the improvement of physical properties of nonfat fermented milk drink was investigated. Drinks were prepared from nonfat milk powder and WPC at different proportions. Rheological properties, serum separation and particle size of the drinks were measured. The effect of WPC on the physical properties of the drinks was evaluated by comparison with those of commonly used stabilizers, including propylene glycol alginate and locust bean gum. WPC addition caused an increase in the consistency coefficient and thixotropy and a decrease in the particle size of the samples. There was no serum separation in the sample with 2% WPC. Large unstable aggregates were observed in the sample with 3% WPC, which also exhibited the highest serum separation. WPC up to a level of 2% positively influenced the physical properties of nonfat fermented milk drink similar to stabilizers.
Fermented milk drinks are consumed especially for their beneficial health effects. Physical properties of fermented milk drinks influence their quality and consumer acceptability. Hydrocolloid stabilizers are used for the improvement of physical properties of fermented milk products. Whey protein concentrates (WPC) with high protein content can be used to substitute hydrocolloid stabilizers. In this study, the effect of the addition of WPC with 75% protein in place of a part of the nonfat milk powder on the physical properties of nonfat fermented milk drink with 6% dry matter was investigated. Use of an appropriate level of WPC was found to be important for obtaining a desirable effect on the physical properties of nonfat fermented milk drink. The effect of WPC was found to be comparable to those of commonly used hydrocolloid stabilizers. Use of WPC also enhances the nutritional value of the product as whey proteins have a high biological value. 相似文献
