Embodiment 1

[0022] (1) Pretreatment of feed liquid: store 25.2 tons of fructose syrup with a mass percentage concentration of 45.0% after isomerization and chromatographic separation in the feed tank, and detect the content of 2-aminoacetophenone in the fructose syrup It was 3.8 μg / kg.

[0023] (2) Adsorption: the pretreated fructose syrup is passed into an adsorption column filled with a macroporous type weakly basic styrene-based anion-exchange resin for adsorption, the macroporous type weakly basic styrene-based anion-exchange resin The volume is V, the feed rate of fructose syrup is controlled at 1.5-2V / hour, so that the content of 2-aminoacetophenone in the fructose syrup discharged from the adsorption column is less than 0.3 μg / kg, and the color of the fructose syrup discharged is Less than 10RBU, light transmittance greater than 95%; when the 2-aminoacetophenone content in the fructose syrup discharged from the adsorption column is greater than 0.3 μg / kg or the color of the fructos...

Embodiment 2

[0030] (1) Pretreatment of feed liquid: 25.2 tons of fructose syrup with a mass concentration of 48.8% after isomerization and chromatographic separation are stored in the feed tank. After testing, the content of 2-aminoacetophenone in the fructose syrup is 4.1 μg / kg.

[0031](2) Adsorption: the pretreated fructose syrup is passed into an adsorption column filled with a macroporous type weakly basic styrene-based anion-exchange resin for adsorption, the macroporous type weakly basic styrene-based anion-exchange resin The volume is V, the feed rate of fructose syrup is controlled at 1.5-2V / hour, so that the content of 2-aminoacetophenone in the fructose syrup discharged from the adsorption column is less than 0.3 μg / kg, and the color of the fructose syrup discharged is Less than 10RBU, light transmittance greater than 95%; when the 2-aminoacetophenone content in the fructose syrup discharged from the adsorption column is greater than 0.3 μg / kg or the color of the fructose syrup...

Embodiment 3

[0038] (1) Pre-treatment of feed liquid: 25.2 tons of fructose syrup with a mass concentration of 52.0% after isomerization and chromatographic separation are stored in the feed tank. After testing, the content of 2-aminoacetophenone in the fructose syrup is 4.2 μg / kg.

[0039] (2) Adsorption: the pretreated fructose syrup is passed into an adsorption column filled with a macroporous type weakly basic styrene-based anion-exchange resin for adsorption, the macroporous type weakly basic styrene-based anion-exchange resin The volume is V, and the feed rate of fructose syrup is controlled at 1.6~1.8V / hour, so that the content of 2-aminoacetophenone in the fructose syrup discharged from the adsorption column is less than 0.3 μg / kg, and the fructose syrup discharged is colored The density is less than 10RBU, and the light transmittance is greater than 95%; when the 2-aminoacetophenone content in the fructose syrup discharged from the adsorption column is greater than 0.3μg / kg or the...

Abstract

The invention provides a method for removing 2-aminoacetophenone in high fructose corn syrup. The method comprises the steps of (1) carrying out material liquid pretreatment, (2) adsorbing, (3) carrying out ion exchange, (4) sterilizing and (5) concentrating to obtain the high fructose corn syrup finished product with the mass percent concentration of 77+ / -0.5%. The method has the advantages of simple technological process, low production cost, and obvious effect of removal of 2-aminoacetophenone. The high fructose corn syrup produced by the method is a colorless and transparent viscous liquid, has high light transmittance, pure smell and good taste, and has the 2-aminoacetophenone content of less than 0.2 [mu]g / kg. Ca<2+>, Fe<3+>, SO4<2-> and other ionic impurities in the high fructose corn syrup can be effectively removed by ion exchange, thus the high fructose corn syrup is further purified, and the high fructose corn syrup quality is further improved.

Description

technical field [0001] The invention relates to a food processing technology, in particular to a method for removing 2-aminoacetophenone in fructose syrup, and belongs to the technical field of food chemical industry. Background technique [0002] 2-AminoacetopHenone (2AP, 2-AAP or AAP for short) is an important trace substance with aroma activity that often occurs in many foods. When the concentration of 2AP in food exceeds a certain threshold, it will cause the so-called "untypical aging" bad smell, referred to as "UTA" phenomenon, the existence of this UTA ​​phenomenon will seriously affect the taste of food and flavor. The detailed formation process of 2-aminoacetophenone has not been completely determined until now, and it can only be roughly speculated and judged based on relevant research. At present, most literatures believe that 2-aminoacetophenone is probably produced by tryptophan or a plant hormone called indole-3-acetic acid (IAA) under certain circumstances. ...
