Abstract

The invention discloses a method for simultaneous detection of 22 kinds of sugars, sugar alcohols and alcohols in fruit juice, which belongs to the field of analytical chemistry. The invention adopts integral pulse amperometric-ion chromatography and optimizes the pretreatment method to study the factors that affect the separation of components. Experimental factors, established a one-time simultaneous detection of 22 kinds of sugars, sugar alcohols, alcohols (2,3-butanediol, propylene glycol, methanol, glycerol, erythritol, xylitol, rhamnose , arabitol, sorbitol, trehalose, galactitol, mannitol, 2-deoxy-D-glucose, arabinose, melibiose, glucose, galactose, fructose, ribose, sucrose, raffinose, maltose) The method solves the technical problem of accurate analysis of multiple components of sugars, sugar alcohols and alcohols in fruit juice. This method is fast, accurate and sensitive, and realizes the simultaneous analysis of multiple categories and components. important contribution.

Description

technical field

[0001] The invention belongs to the field of analytical chemistry, and in particular relates to a method for simultaneously detecting 22 kinds of sugars, sugar alcohols and alcohols in fruit juice. Background technique

[0002] Fruit juice is an important beverage in people's daily life, and fruit juice contains protein, amino acid, sugar, sugar alcohol and other ingredients. Among them, carbohydrates are the main source of energy for people to maintain life activities. Sugar alcohol is a substance formed by the reduction of aldehyde or ketone groups of sugars to hydroxyl groups. It is mainly a sweetener produced by the reaction of corresponding sugars. It will not cause blood sugar to rise, so it has the effect of preventing diabetes and obesity. Alcohols are compounds that contain a hydroxyl group bound to a hydrocarbon group or a carbon on the side chain of a benzene ring in the molecule. Many alcohols are beneficial to human health, but some alcohols hav...
