Embodiment 1

[0017] Embodiment 1: with 100kg rice processing, the preparation process is successively:

[0018] ①Rice washing and soaking: Wash the rice 2 to 3 times, and drain the rice swill. Then control the water temperature to 40°C, add 0.05kg of soda ash, and soak the rice for 1 to 2 hours until it is crushed by lightly rubbing with hands.

[0019] ② Refining: Refining with a refiner, controlling the concentration of rice pulp to 18°Bé, and the degree of crushing at 80 mesh.

[0020] ③ Liquefaction and enzyme inactivation: adjust the pH of the rice milk to 5.8-6.0, add 0.57kg of calcium chloride (dissolved in water and add), add 35ml of liquid high-temperature α-amylase with an activity of 20000U / ml, and mix the rice The slurry is transported to the liquefaction tank, the liquefaction temperature is controlled at 90°C, the liquefaction reaction is 40-60 minutes, and the iodine reaction is measured every 20 minutes, and the liquefaction is completed when the iodine reaction reaches li...

Abstract

The invention relates to a preparation process of rice high fructose syrup, which belongs to the technical field of biological enzymolysis. The preparation process is characterized by comprising the following process steps of: washed rice soaking; thick fluid grinding; liquefaction and enzyme inactivation; rice dreg filtration; saccharification and enzyme inactivation; decolorization and filtration; ion exchange and concentration; isomerization; secondary decolorization and filtration; and secondary ion exchange and vacuum concentration, wherein when the syrup concentration reaches 70 to 75 percent, the concentration is stopped to obtain a finished product, namely 42% high fructose syrup. The preparation process directly takes rice as a raw material to produce the high fructose syrup through a biological enzymolysis technique, thereby not only saving a process step of preparing starch from foodstuff and greatly reducing the production cost, but also promoting intensive processing of the rice, bringing the utilization value of the rice into play to the utmost extent, and strongly promoting the diversified development of grain processing enterprises.

Description

technical field [0001] The invention relates to a preparation process of rice fructose syrup, which belongs to the technical field of biological enzymolysis. Background technique [0002] Fructose syrup is a colorless or light yellow transparent liquid, the main components are fructose and glucose, it has fruit flavor and pure sweetness, the sweetness is equivalent to that of sucrose, it is easy to use, stable in nature, especially cold and sweet. High fructose syrup is widely used in beverage, food, health products and other industries due to its excellent properties, and it is a high-quality food ingredient that conforms to popular trends. Beverage giants such as Huiyuan, Nongfu Spring, Hand in Hand, and Baige all use fructose syrup in their juice drinks. The sweetness of fructose syrup is comparable to that of white sugar, and it has the advantages that white sugar does not have. It is the best product for various food manufacturers to replace white sugar. And the price...
