Preparation method of invert syrup

[0044] In order to obtain a conversion syrup with a conversion of 47%, prepared by the following steps:

[0045] (1) Soluble: The white sugar is stirred with hot water at 85 ° C to dissolve a sugar solution of 6 kg of mass concentration of 60%;

[0046] (2) Hydrolysis: Adding anhydrous citric acid to the sugar solution to adjust the pH to 2.55, 85 ° C. After stirring for 2 h, it is obtained to obtain a hydrolyzate, take a small amount of hydrolyzate to cool to room temperature, and measure the hydrolyzate of BRIX to 73.6%. The specific gravity is 1.35, the rotation degree is 139.3, and the conversion of the hydrolyzate is 99.38% by calculation.

[0047] (3) Precation: The hydrolyzed solution is lowered to 70 ° C in 0.5 h and the calcium hydroxide adjustment pH to 4.5 is added to the hydrolyzate, 6.686 kg of a sugar solution (60% mass concentration is 60%) and the hydrolyzate It was mixed, and the mixed mixture was lowered to 60 ° C and the calcium hydride hydroxide was continued to t

[0053] In order to obtain a conversion syrup with a conversion of 30%, prepared by steps:

[0054] (1) Soluble: The white sugar is stirred with hot water at 85 ° C to dissolve a sugar solution of 6 kg of mass concentration of 60%;

[0055] (2) Hydrolysis: Adding anhydrous citric acid to the sugar solution to adjust the pH to 2.55, 85 ° C to obtain a hydrolyzate, take a small amount of hydrolyzate to cool to room temperature, and measure the brix of the hydrolyzate to 63.5, specific gravity In a 1.312, the optical rate is 150.45, by calculating the concentration of the hydrolyzed solution is 96.27%;

[0056] (3) Addition: Mix the prepared hydrolyzate directly with a glycose solution (mass concentration of 50%) (mass concentration of 50%), and the mixed mixture is lowered to 60 ° C and hydroxide is added to the mixture. Calcium to make the mixture of pH of 5.0;

[0057] (4) Decolorization filtering: After mixing the mixture in step (3) and the activated carbon, then filtrate and mixed
