2. Operation points
2.1 Cleaning, selection and washing of raw materials: Remove the fruits that are spoiled due to heat, and the hawthorns that are serious pests and diseases, and clean and remove sediment and impurities.
2.2 Slicing and Drying: The hawthorn is cut into 2 to 3 flaps with a stainless steel knife, and then put into an electric blast oven to dry it. About 1 kg of fresh fruit is about 0.4 kg dry tablets.
2.3 Extraction: The extraction temperature is 75°C, the extraction time is 1h, and the feed water ratio is 1:7.
2.4 Coarse filtration: After leaching, the juice is filtered with a 150 mesh stainless steel screen, or it can be filtered with 4 to 5 layers of gauze.
2.5 Clarification: Select clarifiers to clarify hawthorn juice beverages in an amount of 0.05 to 0.10%.
2.6 Fine filtration: The clarified juice is filtered through a 200 mesh stainless steel screen.
2.7 Deployment: The ratio of hawthorn juice beverages to raw materials: hawthorn juice 50%, granulated sugar 8 to 11%, VC 0.2 to 0.3%, honey 0.2%, edible flavor 0.1%.
2.8 Canned and Sealed: The beverage is heated to 93°C, kept for 10 to 15 minutes and canned immediately. After the glass bottle is preheated and then canned, the hawthorn juice drink should be filled at a temperature of more than 85°C, and it must be filled after assembly, and a certain degree of vacuum is generated after cooling.
2.9 Sterilization, cooling, and finished products: Sterilization formula 3′～4′～5′/100°C, and cooling adopts gradual cooling method.
3. Product quality standards
3.1 sensory index color: light red, orange red or red, uniform.
Aroma: It has a unique aroma of hawthorn and must not have foreign aroma and odor.
Taste: sweet and sour taste, pure taste, no smell, refreshing.
Organization status: clear and transparent, no obvious visible impurities, a small amount of precipitation is allowed after standing for a long time, but after the shake is still the original uniform state.

Hawthorn juice drink production process
With the improvement of people's living standards, people's dietary structure tends to develop nutrition and health functions and green pollution-free foods. Hawthorn, a green food ingredient, is rich in carbohydrates, amino acids, organic acids, vitamins (especially VC), minerals, and trace elements. It also contains flavonoids, quercein, and hyperoside. Such biologically active ingredients have certain health functions. This article describes a hawthorn juice beverage processing method for your reference.
