Description

Technical Field

[0001] The utility model relates to the technical field of beverage processing, in particular to a pectin adding system. Background Art

[0002] Pectin is used in the food industry as a food additive or ingredient, mainly for gelling, thickening, improving texture, emulsifying and stabilizing. Pectin is hydrolyzed into water-soluble pectin, so that the pectin is transferred to the water phase to form water-soluble pectin, which is then used in the food and beverage industry. Adding appropriate water-soluble pectin can increase the thickness of fruit juice drinks and the fluidity of fruit juice drinks, making the taste smoother.
