Problems solved by technology

The beverages currently produced are all made from wolfberry extract juice, with incomplete nutritional value, poor flavor, low market acceptance, or compounded with other raw materials, which cannot highlight the nutrition and characteristics of wolfberry, and have not been recognized by the market.
[0005] The publication (announcement) number is CN107125525A, and the invention patent application number is CN201710544495.8 discloses "A Method for Plant Probiotics to Ferment Wolfberry Pulp", which solves the problems of low-acidity Lycium barbarum pulp with short shelf life, poor product flavor and processing cost. high and serious nutrient loss during processing, the inventive method is completed through the steps of pretreatment, crushing, enzymolysis, beating, primary sterilization and cooling, fermentation, centrifugation, degassing, homogenization, secondary sterilization and cooling, and aseptic filling. The invention uses different lactic acid bacteria to ferment the weakly acidic wolfberry pulp to produce a large amount of organic acids such as lactic acid, thereby reducing its pH and producing a better fermentation flavor, reducing the sterilization conditions, saving costs and retaining the wolfberry self-nutrition and increase the nutrient content of fermentation products; meanwhile, the fermented wolfberry pulp is separated and removed by a decanter centrifuge to effectively improve the stability of the fermented wolfberry pulp in the beverage industry. However, the wolfberry pulp contained in the wolfberry pulp is relatively less, the color of the pulp is light, the flavor is poor, and the nutritional value decreases

Abstract

The invention discloses a preparation method of probiotics-fermented Chinese wolfberry concentrated slurry. The preparation method comprises the following steps of crushing fresh Chinese wolfberry, dried Chinese wolfberry and Chinese wolfberry powder, so as to obtain Chinese wolfberry slurry, wherein the content of soluble solids is controlled to 15 to 30%; treating by ultrasonic waves, standing and hydrolyzing by enzyme, sterilizing, and inoculating with probiotics; warming at the temperature of 20 to 45 DEG C, and fermenting; naturally stopping fermenting, or finishing fermenting when the pH(potential of hydrogen) value reaches 3.0 to 4.5, so as to obtain probiotics-fermented Chinese wolfberry raw juice; separating the probiotics-fermented Chinese wolfberry raw juice, so as to obtain probiotics-fermented Chinese wolfberry paste; mixing 10 to 50% of probiotics-fermented Chinese wolfberry raw juice and 0 to 10% of probiotics-fermented Chinese wolfberry paste, and adding a proper amount of honey, syrup or white granulated sugar, stabilizer, sodium citrate, essence, sodium erythorbate, oligosaccharide, lutein, taurine, zinc gluconate, Vc (vitamin c) and other nutrition enhancers, soas to obtain the probiotics-fermented Chinese wolfberry concentrated slurry. The obtained probiotics-fermented Chinese wolfberry concentrated slurry has the advantages that the rich nutrients are contained, the color is bright and attractable, the flavor is elegant, and the bioactivity is higher.

Description

technical field [0001] The invention belongs to the field of food and beverage processing, and in particular relates to a method for preparing probiotic-fermented wolfberry thick pulp. Background technique [0002] Lycium barbarum is both a drug and a food item announced by the Ministry of Health. The "Pharmacopoeia of the People's Republic of China" clearly stipulates: "Medicinal wolfberry is the dried and mature fruit of Lycium barbarum in Ningxia". The powerful and extensive health functions of wolfberry make it one of the best raw materials for the production of various health care products. Therefore, the production of health food has become the development direction of deep processing of wolfberry. [0003] V contained in wolfberry A , V B , Vc and V E All have strong antioxidant capacity, especially the Vc in the water phase and the V in the lipid phase E , has become the standard substance of the corresponding antioxidant effect. Lycium barbarum contains a large...
