Chinese wolfberry not only has good medical and health care function, but also contains a variety of nutrients, including 5.8g protein, 1g fat (linoleic acid), calcium 155mg, phosphorus 67mg, iron 3.4mg, carotene 3.96mg, vitamin B10.23 mg, vitamin B20.33 mg, nicotinic acid 1.7mg, vitamin C3 mg, carbohydrate 31.44g, betaine, etc., which is a rare resource for both medicine and food.

Using pest-free and non-rotting dried Chinese wolfberry as raw material, the wolfberry cola beverage made by scientific method has the unique aroma and cool taste of Chinese wolfberry and cola beverage, and has good nutrition and health care function.

1. Raw materials and main equipment

1) Raw materials: Chinese wolfberry, white granulated sugar, compound stabilizer, compound spice, compound sweetener, etc., all of which are edible grade in the market.

2) main equipment: beater, sandwich pot, extraction tank, sterilizer, filling machine, etc.

2. Technological process

Lycium barbarum → impurity removal → cleaning → soaking → juice → sterilization → CO2 → well water or tap water → bar filtration → water purifier → sodium ion exchanger → ultrafiltration → ultraviolet sterilization-→ sugar → sugar → filter → ingredients mixed → filling → cover → label packing

3. Operation essentials

The main results are as follows: 1) preparation of Chinese wolfberry juice: take high-quality Chinese wolfberry without diseases, insect pests and mildew, after cleaning, add 5 times boiling water and cover to soak 30min, beat the pulp to facilitate rapid extraction, then extract it in a sandwich pot for 12 hours under the condition of 70 ℃ and 80 ℃, then repeatedly extract once, and then mix the juice twice to get the original Chinese wolfberry juice.

2) blending: through experimental study, the best formula of wolfberry cola beverage was selected as follows: 10% of wolfberry juice, 5% of granulated sugar, 1% of compound sweetness, 0.2% of vitamin C0.2, 0.025% of quality improver A0.025%, 0.1% of compound stabilizer, 0.15% of compound essence and 100% of softened water. When blending, the sugar is first mixed into syrup, then the prepared Chinese wolfberry juice, syrup and cold water are added to the preparation tank in proportion, and the prepared slurry is poured into the mixer and fully mixed with CO2 gas.

3) filling and capping: the mixed slurry is filled into washed and sterilized cans, glass bottles and polyester bottles by equal pressure filling machine, and then capped and sealed, in order to ensure the quality of the finished products, the environmental hygiene of the workshop must be strictly controlled in the whole operation process, the filling workshop must be separated separately, and the air must be purified.

4) labeling and packing: label the sealed finished products, and then pack them into storage respectively.

4. Product quality index (established according to GB/T10792-1995)
