Processing technology for ice cream containing coffee pulp pigment powder

Abstract

The invention belongs to the technical field of coffee pulp processing and discloses a processing technology for ice cream containing coffee pulp pigment powder. The technology comprises the followingsteps: selecting fresh coffee pulp and peeling, thereby acquiring the coffee pulp; placing the coffee pulp into a vacuum freeze dryer for performing vacuum freeze drying; utilizing a crushing machinefor crushing the dry coffee pulp, thereby acquiring coffee pulp powder; dissolving the coffee pulp powder with alcohol, concentrating, extracting and separating pigment and then freeze-drying into powder; ultrasonically sterilizing the coffee pulp pigment powder solution; preparing a mixed solution of saccharose and additive; ageing and cooling for 5h. The damage of the ultrasonic sterilization to the active ingredients of the coffee pulp powder solution is ultra-less, so that the acquired coffee pulp pigment ice cream has more healthcare functions; the coffee pulp is rich in organic nutrient, mineral nutrient and anthocyanin; the anthocyanin has various healthcare effects, such as, skincare, anti-ageing effect, prevention for cardiovascular diseases and cancers; the processing technologyhas great promoting and boosting functions for the research and application of the coffee pulp.

Description

technical field [0001] The invention belongs to the technical field of coffee pulp processing, in particular to an ice cream processing technology containing coffee pulp pigment powder. Background technique [0002] Existing technology and its existing problems [0003] 1. In the production process of ice cream, synthetic pigments are commonly used. Common colorants in ice cream processing include tartrazine, sunset yellow, amaranth and other pigments. Lemon yellow, also known as tartrazine, acid light yellow, hydrazine yellow, chemical name is 1-(4-sulfonic acid phenyl)-4-(4-sulfonic acid phenylazo)-5-pyrazolone-3 -Carboxylic acid trisodium salt, a water-soluble synthetic pigment. Sunset yellow is a water-soluble azo colorant, chemical name 1-(4′-sulfo-1′-phenylazo)-2-naphthol-6-sulfonic acid disodium salt, a commonly used artificial food coloring , Stable properties and lower prices, widely used in food and drug coloring. Amaranth is a water-soluble azo colorant whose...
