Abstract

The development of the processing technology and a complex stabilizer for the peanut protein beverage processed was presented in this study. The suitable peeling conditions for peanut were: to made it soak with soft water containing 5% $NaHCO_3$ for 12 h. The best homogenizing temperature, pressure and times were 75°C, 30MPa and twice. The sterilization condition of 121°C and 15 min was the foundation to achieve the best stability. The composition of the stabilizer was optimized by uniform design combined with regression analysis based on sensory evaluation, which was achieved using fuzzy comprehensive evaluation method. The 100 mL of peanut protein beverage added with 0.4 g of sodium carboxymethyl cellulose (CMC-Na), 0.2 g of sodium alginate and 0.6 g of gelatin displayed good stability. CMC-Na amount had the largest effect on beverage stability and the effect of gelatin amount was the smallest. The peanut protein beverage with added optimized complex stabilizer was medium preference grade.
