Abstract

The invention discloses a health blueberry concentrated solution and a production technology thereof. The production technology comprises the following steps that 1, blueberries are washed with waterand drained; 2, the drained blueberries, water, antioxidant silkworm pupa protein and a plant antioxidant are added into a pulping machine for pulping to obtain pulp; 3, the pulp is filtered through aplate-frame filter to obtain a filtrate; 4, the filtrate is concentrated in vacuum to obtain a concentrated solution; 5, ultra-high-temperature instant sterilization is carried out. The health blueberry concentrated solution is good in taste, rich in fruity flavor, mellow in flavor, slightly sour, sweet and tasty, the degradation loss of blueberry nutrients is reduced by controlling processing factors and antioxidant treatment in the processing process, nutrients and effective components of the blueberries are maintained, the product quality is improved, and the health blueberry concentratedsolution has the effects of improving human immunity, beautifying faces, resisting aging, preventing cancer and the like after being drunk for a long time.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a health-care blueberry concentrate and a production process thereof. Background technique [0002] In addition to conventional sugar, acid and VC, blueberry fruit is rich in VE, VA, VB, SOD, arbutin, protein, anthocyanin, dietary fiber and rich in K, Fe, Zn, Ca and other mineral elements. According to the analysis and determination of 14 varieties of blueberry fruit imported from the United States, the content of anthocyanin pigment in every 100 grams of blueberry fresh fruit is as high as 163mg, protein 400-700mg, fat 500-600mg, carbohydrate 12.3-15.3mg, vitamin A As high as 81-100 international units, vitamin E2.7-9.5 micrograms, SOD5.39 international units, high vitamin content. Trace elements are also very high, calcium 220-920 micrograms per gram of fresh fruit, phosphorus 98-274 micrograms, magnesium 114-249 micrograms, zinc 2.1-4.3 micrograms, iron 7.6-30.0 micro...
