Shanghai green celery compound beverage processing technology
Abstract: Shanghai qing and celery as raw material, developed a new type of composite beverage processing technology, by using orthogonal experiment design, enhance the output rate of juice, remove chlorophyll, protecting color products, the best way to improve the sensory evaluation and the best mix ratio, through sensory evaluation, determination of the project such as absorbance, selected Shanghai green celery the best formula of compound beverage, the results show that the Shanghai green section 6 cm, with 100 ℃ hot water hot 7 min, asparagus juice yield the highest. Best formula is: stabilizer.color-protecting CaCl 2%, stabilizer.color-protecting NaSO3 4%, sugar 2.5%, citric acid 0.003%, Shanghai green: celery is 2:1, juice content 50%.
