Water soluble dietary fiber is a kind of macromolecular polysaccharide which is difficult to be digested by enzyme in human body, but it has many functions and is an ideal functional health food raw material. In this paper, the water-soluble dietary fiber produced by Tianjin Institute of light industry was used as the basic raw material to develop dietary fiber juice beverage, dietary fiber low calorie carbonated beverage and ordinary carbonated beverage. The effects of dietary fiber on juice drinks and carbonated drinks were studied. The results showed that the addition of water-soluble dietary fiber to clarified juice drinks and carbonated drinks would not cause precipitation, and would not affect the clarification and shelf life of juice. The best addition and formula of dietary fiber were determined by experiment, and the sugar content was 10.8% ° The results showed that the juice beverage with BX, ph3.20 and 4% dietary fiber was light yellow, clear and transparent; The low calorie dietary fiber carbonated beverage with dietary fiber content of 2.5%, sugar content of 5% (refractometer), caloric content of less than 70 kJ / 100 ml and ordinary dietary fiber carbonated beverage with sugar content of 10% (refractometer).
