The process technology and stability of the compound health-care beverage of red raspberry and coix kernel

The recipe and stability of the compound health- care beverage of red raspberry and coix kernel were researched.The optimization formula of the compound beverage using red raspberry and coix kernel as main material was studied by single- factor experiment and the quadratic regression orthogonal combination test and the stability of the compound health- care beverage was studied. The results indicated that the best compound beverage recipe was red raspberry juice 25.92g, coix kernel juice 24.90g, sugar 5.64g and water 143.54g. The complex stabilizers of 0.09% xanthan gum and 0.03% guar gum worked well.The results provided feasible process and formula for the exploitation of the red raspberry and coix kernel.
