Problems solved by technology
Since the demand for oil is very large, the accompanying by-products will also increase greatly. If a large amount of by-product glycerin is not used reasonably, it will not only waste resources, but also may pollute the environment.
In traditional industrial production, pure glycerin is usually used as raw material to synthesize glyceryl monostearate, and the by-product oil is not rationally utilized

Embodiment Construction
[0034] The production process of the high-purity monoglycerides described in the present invention will be further explained and illustrated in conjunction with the accompanying drawings and specific examples below. However, the explanations and illustrations do not constitute undue limitations on the technical solution of the present invention.
[0035]The high-purity monoglyceride of embodiment 1-9 adopts following steps to make (concrete process parameter is listed in table 1-1, table 1-2, table 1-3 and table 1-4):
[0036] (1) Put deodorized oil containing a mixture of monoglycerides and diglycerides or raw material oil of triglycerides in a reaction tank at 80-90 ° C for pretreatment, and maintain the pressure in the reaction tank <50mmHg to remove raw materials air in oil;
[0037] (2) Mix the raw material oil with the alkali, and stir evenly to obtain the mixture, wherein the weight ratio of the alkali to the raw oil is 0.1%-0.5%, and the stirring can be mechanical stir...

Abstract
The invention discloses a production process of high-purity monoglyceride. The method comprises the following steps: (1) putting raw oil into a reaction tank, carrying out pretreatment to remove air in the raw oil, wherein the raw oil comprises deodorized oil containing a mixture of monoglyceride and diglyceride or comprises triglyceride; (2) mixing the raw oil with alkali, and carrying out uniform stirring to obtain a mixture, wherein a weight ratio of the alkali to the raw oil is 0.1-0.5%; (3) heating the mixture to 110-130 DEG C, conducting stirring to remove moisture, raising a temperatureto 165-205 DEG C and carrying out mechanical stirring; (4) neutralizing a mixture by using an acid solution after a reaction is completed; (5) cooling a finished reaction product, namely a monoglyceride mixture obtained after the reaction is completed; and (6) purifying the monoglyceride mixture by adopting short-diameter molecular distillation equipment, wherein the operating temperatures of a film evaporator and a molecular distiller of the short-diameter molecular distillation equipment are controlled to be 150-220 DEG C, the flow velocity of the monoglyceride mixture is controlled to be 1-2 mL / min, and the vacuum degree of the film evaporator and the vacuum degree of the molecular distiller are controlled to be 0-50 mmHg.
Description
technical field [0001] The invention relates to a production process, in particular to a production process of monoglyceride. Background technique [0002] As one of the important additives in food, emulsifiers are of various types and are often used in baking, mayonnaise, formula drinks, chocolate making, dough modification and other food processing. Among them, glyceryl monostearate is a common additive in food and candy. It can be added not only as an emulsifier in chocolate, margarine and ice cream, but also as a surfactant in condensed milk, malted milk, cheese, instant In dairy products such as whole milk powder. Monoglyceride is a good emulsifier, which can effectively improve the instant solubility, prevent agglomeration and agglomeration resulting in precipitation, and then effectively improve product quality. Adding it as an additive in feed can improve the anti-caking and anti-oxidation properties of the feed. Extend the shelf life of feed. In medicine, monogly...
