Abstract

The invention discloses a method for synchronously producing low-calorie syrup containing trehalose and erythritol, and belongs to the technical field of functional sugar production. The invention discloses a method for synchronously producing low-calorie syrup containing trehalose and erythritol, which comprises the following steps of: liquefying starch serving as a substrate into maltodextrin by using high-temperature amylase; the preparation method comprises the following steps of: inoculating the raw materials into a fermentation tank, sterilizing, inoculating candida lipolytica, simultaneously adding maltooligosyl trehalose synthase and maltooligosyl trehalose hydrolase, fermenting for 20-24 hours by controlling a certain fermentation condition in the initial stage, and adding saccharifying enzyme to decompose residual sugar into glucose; and carrying out plate-frame pressure filtration on the fermentation liquor to remove yeast, decolorizing with activated carbon, desalting with resin, and concentrating to obtain the low-calorie functional syrup containing trehalose and erythritol and having DS of 70-80%. The method disclosed by the invention has the characteristics of simplicity, feasibility, low pollutant emission, low operation cost, high product quality, suitability for industrial production, remarkable economic and social benefits and the like.

Description

technical field [0001] The invention relates to the technical field of functional sugar production, and more specifically relates to a method for synchronously producing low-calorie syrup containing trehalose and erythritol. Background technique [0002] Sweetness is the food taste that human beings instinctively seek, and syrup is one of the substances that can provide sweetness. Because the sugar content is very high, the syrup can be stored for a long time even if it is not refrigerated in a sealed state, and it is more convenient to use. It can be used to make drinks or make sweets. However, syrup has high energy and will bring huge physiological pressure to the body after ingestion, which can easily cause diseases such as diabetes, heart disease, tooth decay and cancer. Excessive sugar content and calories are considered to be one of the main factors leading to obesity. Although there is no significant evidence to prove that obesity is directly related to diabetes and ...
