The development of Brown Rice Syrup Drink
Abstract: This study aims to make a brief study of the processing technology of brown rice syrup drink by using brown rice as raw materials, pure milk for the materials, and other flavorings such as honey and sugar. It not only discusses the quality ratio of brown rice and water, the best dosage and most suitable time of starch hydrolysis, the volume ratio between rice and pure milk, but also studies the stability and the best formula of the flavoring of the product. The results show that the best quality ratio of rice and water is 4:10; the dosage of α-amylase should be 0.06% while the required time for hydrolysis is 2.5h and the temperature is 70℃ according to the technical parameters for the hydrolysis; the best volume ratio of rice and milk is 10:5; The best quality ratios of stabilizers and main materials are 0.1%(xanthan gum) and 0.2%(CMC-Na); The best formula of the flavoring is 2% of honey, 2.5% of sucrose and 0.05% of citric acid.
