Embodiment 1

[0019] (1) Remove impurities such as bran powder and rice husk in the raw rice, add water equivalent to 4 times the weight of the raw rice and soak for 5 hours, refine into a slurry, and pass through a 70-mesh filter;

[0020] (2) adjust the pH value of the slurry to be 5.8, the Baume concentration of the slurry is 17Be °, add high temperature resistant α-amylase, the amount of high temperature resistant α-amylase is equivalent to 0.15% of the weight of the rice raw material, stir and mix;

[0021] (3) Spray the slurry at 108°C, lower the temperature to 95°C, control the DE value of the liquefied liquid to 16, and filter it with a filter press to obtain a clear liquid without rice dregs;

[0022] (4) Cool the feed liquid to 59°C, adjust the pH value to 5.5, add 0.25% of the weight of rice raw material suitable for saccharifying for 9 hours; then add 0.15% of the weight of rice raw material to continue saccharifying for 16 hours , when the DE value of the feed liquid is 46, the...

Embodiment 2

[0029] (1) Remove impurities such as bran powder and rice husk in the rice, add water equivalent to 3 times the weight of the raw material of rice and soak for 6 hours, refine into a slurry, and pass through a 60-mesh filter;

[0030] (2) Adding enzyme to adjust slurry: adjust the pH value of the slurry to 5.6, the Baume concentration of the slurry is 19Be°, add high-temperature-resistant α-amylase, the amount of high-temperature-resistant α-amylase is equivalent to 0.1% of the weight of the rice raw material, stir and mix;

[0031] (3) Liquefaction and deslagging: spray the slurry at 106°C, cool it down to 95°C, control the DE value of the liquefied liquid to 14, and filter it with a filter press to obtain a clear liquid without rice dregs;

[0032] (4) Cool the feed liquid to 58°C, adjust the pH value to 5.2, add 0.2% of the weight of rice raw material suitable for saccharifying for 10 hours; then add 0.1% of the weight of rice raw material to continue saccharifying for 20 ho...

Embodiment 3

[0039] (1) Remove impurities such as bran powder and rice husk in the rice, add water equivalent to 5 times the weight of the raw material of rice and soak for 3 hours, refine into a slurry, and pass through an 80-mesh filter screen;

[0040] (2) adjust the pH value of the slurry to be 6.1, the Baume concentration of the slurry is 19Be °, add high temperature resistant α-amylase, the amount of high temperature resistant α-amylase is equivalent to 0.2% of the weight of the rice raw material, stir and mix;

[0041] (3) Spray the slurry at 110°C, lower the temperature to 95°C, control the DE value of the liquefied liquid to 19, and filter it with a filter press to obtain a clear liquid without rice dregs;

[0042] (4) Cool the feed liquid to 60°C, adjust the pH value to 5.9, add 0.3% of the weight of rice raw material suitable for saccharifying for 8 hours; then add 0.1% of the weight of rice raw material and continue saccharifying for 20 hours , when the DE value of the feed liq...

Abstract

The invention discloses a method for preparing high-purity maltose syrup by adopting rice as raw material, comprising the following steps of: (1) removing the impurity in the raw material rice, adding water for soaking, grinding the syrup into grout, and filtering; (2) mixing the grout, adding high temperature-resistant Alpha amylase, stirring and mixing evenly; (3) carrying out liquefaction and discharging slag; (4) saccharifying; (5) neutralizing, decoloring and filtering; (6) carrying out ion exchange refining; (7) concentrating; and (8) packaging. The obtained dried high-purity maltose syrup has the maltose content of 80 to 86%.

Description

technical field [0001] The invention relates to a method for preparing maltose syrup, in particular to a method for preparing high-purity maltose syrup from rice. Background technique [0002] my country's current sucrose production is relatively large, with an annual output of about 10 million. However, excessive intake of sucrose is also more harmful to the human body. With the continuous improvement of people's living standards, the requirements for food quality are also getting higher and higher. The development of new sugar products with rich nutrition, good taste, low calorific value and good processing performance and their preparation methods has become a research hotspot in the world. The preparation method of starch sugar is one of the research hotspots. [0003] Starch sugar series products mainly include maltose, isomerized maltose, glucose, fructose syrup, maltodextrin, glucose and oligosaccharides (trisaccharides, tetrasaccharides, etc.). Starch sugar has t...
