Optimization of the stabilizer of compound beverage of grape seed and chick pea by response surface methodology
The effect of different stabilizers on the stability of compound beverage to select the best compound stabilizer.The beverage was made by grape seed and chick pea.Five different stabilizer including xanthan gum,carrageenan,pectin,sodium carboxymethyl cellulose (CMC-Na),sodium alginate were chosen to perform the single factor test.The stability coefficient,sedimentation rate were the indexes,three better stabilizers were selected and compound stabilizer was optimized by response surface method.The results showed that the best formula was sodium alginate 0.04%,xanthan gum0.04%,pectin 0.04%.The stability coefficient was 98.877%,the average precipitation rate was 1.064%.The conclusion is that the compound stabilizers can improve the stability of the beverage.
