(five) operation instructions
(1) Silver almond processing
1 Preservation of silver almond raw material: Silver almond, also known as ginkgo, will be used to manually remove the ginkgo after removing the bad fruit and manually remove the leather garment. If the production volume is large, the ginkgo can be dried first, and then peeled with a roller sheller.
2 Baking: Place the peeled nuts on a tray and bake them in an oven. The thickness of the nuts on the tray does not exceed 3 cm. The temperature starts at 85-90°C for 1.5 hours, and then it is placed at 115-120°C. The time is 2 hours until the white nuts are yellow in color or dark in color, and the odor is baked scented type.
3 Soaking: According to the weight ratio of 1:3, the roasted nuts and the treated softened water are soaked. The water temperature is 65-70°C and the time is 2.5 hours.
4 Beating and colloidization: Beating with a single-channel horizontal beater, beating and then diluting the pulp juice with demineralized water for 1 time, then grinding with a colloidal colloid mill for 15 minutes, and adjusting the particle size to 5 microns or less.
5 Homogeneous: The material temperature is about 35°C and homogenized with a pressure of 25 MPa.
(2) Hawthorn processing: after removing the dried rot fruits, pests and diseases, etc., the hawthorn is washed twice with fresh water, broken into small pieces with a hammer mill, and then placed in a stainless steel tank and added at about 85°C. The demineralized water was just immersed in the raw materials, and the temperature was maintained at about 85°C. After 2 hours, the juice was filtered out. Then, the remaining filter residue was added with softening water at about 85°C that was just immersed in the filter residue, and the filtrate was filtered after 2.5 hours. The two filtrates were combined and filtered with a flannel for later use.
(3) Treatment of other raw materials: Dissolve 75% syrup, add 0.5% citric acid to facilitate the removal of impurities in the sugar and filter it with a sugar filter. Dissolve 5% sodium alginate and 2% sucrose ester solution.
(4) Formulation: The following proportions were formulated: 500 g of white juice, 1000 g of hawthorn juice, 250 g of 75% syrup, 30 g of 5% sodium alginate, and 50 g of 2% sucrose ester.
(5) Homogenization: The homogenized material is homogenized twice at a pressure of 16-18 MPa.
(6) Instantaneous temperature rise: The material is heated to above 85°C with a high-temperature instantaneous sterilizer, and the material is hot-filled and hot-sealed.
(7) Sterilization: The sealed cans were sterilized in hot water at 95°C or more for 15 minutes.
