Technical requirements for quality of Liuquqiong sugar (1) Requirements for raw materials and accessories. In the protected area, the tested millet, sesame, barley and high quality well water with a pH of 6.8 to 7.2. (2) Processing technology. 1. Production process: material selection → rice washing → soaking → steamed rice → saccharification (dilution → barley malt production → saccharification) → dripping juice → sugar → sugar → block → shabu-shabu (fried rice → shabu-shabu) → 擀Blank → cut strip, slice → package 2. Production operation requirements: (1) soaking: soak the millet in normal temperature water for 8h to 10h. (2) Steaming: The soaked millet is steamed in a steamer for 65 minutes to 70 minutes. (3) Saccharification: Dilute the prepared barley mash slurry and water in a ratio of 1:1.2 to 1:1.5 and stir the rice to 60 °C to be evenly immersed in a large cylinder. The temperature in the cylinder is controlled at 55 °C. Up to 60 ° C, time 180 min. (4) Production of barley malt: The selected barley is soaked in natural well water, 2h in summer and 4h in winter, and then piled up in a sheltered and humid place to grow naturally. Wash once every 12h in summer, once every 24h in winter, then remove and stack, then repeat for 7 to 8 days, until the barley malt grows into the rear. (5) Juice: After the saccharification is finished, the water of 90 ° C to 100 ° C is added to the saccharification tank for 120 minutes, and the juice is started to be drenched. (6) Sugar: Put the leached juice in a large iron pot. First fire, after a small fire, the temperature of the sugar is controlled in the range of 95 ° C to 105 ° C, when the juice is smashed into a line, start stirring constantly. Twisted for 2.5 h to 3 h, placed successively on a bluestone cutting board for cooling to 60 ° C to 70 ° C. (7) Pulling sugar: The cooled sugar is repeatedly pulled under the hot steam, and the color changes from yellow to white. (8) Blocking: The drawn sugar is made into irregular small pieces. (9) Shabu-shabu: The fried sesame and sugar pieces are divided into 1.2:1 to 1.5:1 ratio of peeled sesame seeds, and the ratio of sesame seeds is 1:1 to 1.3:1, and the layers are evenly distributed in the pots. The pot was placed in an insulated container and tanning for 10 min. (10) 擀 :: Place the mashed mixture on the chopping board, mix it evenly, and press it into a cake with a thickness of 2cm to 3cm. (11) Sectioning: Cut into strips or sheets as required. (3) Quality characteristics. 1. Sensory characteristics: The color of the products processed by the white sesame seeds is beige; the products processed by black sesame are black and white, and the color is uniform. The tissue pores are evenly distributed without irregular large voids. The scent is crispy and sweet, with no sticky teeth and no odor. The morphological products are strip-shaped and flaky. Strips and flaky cuts are neat and uniform in thickness. 2. Physical and chemical indicators: The project requires protein (g/100g) ≥ 11 fat (g/100g) ≥ 18 moisture content% ≤ 3 reducing sugar % ≥ 183. Safety requirements: Product safety indicators must meet the relevant regulations of the state for similar products.
