Problems solved by technology

However, when this method is used in the processing of wet vermicelli, vermicelli, and vermicelli, the addition of malt powder is easy to bring in bacteria, resulting in a short shelf life for fresh and wet starch products, which will quickly swell the bag and deteriorate by fermentation.
[0004] In order to solve the problem of short shelf life of fresh and wet starch products, the shelf life of products has been improved by adding formaldehyde, scallops, borax, sodium benzoate, potassium sorbate, sodium metabisulfite, sodium EDTA-2, alum, etc., but starch The problem of further biohardening of the gel system is still difficult to solve, and the product quality will quickly deteriorate

preparation example Construction

[0036] The present invention also provides the preparation method of the organic acid glyceride starch described in the above technical scheme, comprising the steps of:

[0037] 1) mixing raw materials except starch, sodium dehydroacetate and water, and carrying out esterification reaction to obtain organic acid glyceride;

[0038] 2) adding water to the organic acid glyceride obtained in the step 1) until the water content is 10wt.% to 30wt.%, to obtain an organic acid glyceride aqueous solution;

[0039] 3) adding sodium dehydroacetate and starch to the organic acid glyceride aqueous solution obtained in the step 2), and continuing the esterification reaction to obtain organic acid glyceride starch.

[0040] In the invention, raw materials except starch, sodium dehydroacetate and water are mixed for esterification reaction to obtain organic acid glycerides. In the present invention, the mixing method is preferably stirring and mixing, and the stirring condition is preferably ...

Embodiment 1

[0064] Preparation of organic acid glyceride pea starch

[0065] Step 1: Take 500Kg of edible glycerin, 75Kg of sodium lactate (the mass percentage of sodium lactate≥60%), 15Kg of lipase, 200Kg of citric acid, and 25Kg of glacial acetic acid; Stir at a speed of 3000r / min to homogeneously mix, keep warm and esterify for 30 minutes, then add 200Kg of drinking water, stir at a speed of 3000r / min to homogeneously mix, so that the product has good fluidity and obtains a microemulsion;

[0066]Step 2: Take 750Kg of pea starch and 1Kg of sodium dehydroacetate, put them in a ribbon mixer, put a hot water bath into the interlayer of the mixer, start the mixer, stir at a speed of 20r / min, and pump into step 1 250Kg of microemulsion is heated up to 50°C, the temperature does not exceed the initial gelatinization temperature of the starch used, and the esterification is carried out under stirring for 1 to 2 hours to obtain organic acid glyceride pea starch.

Abstract

The invention belongs to the technical field of modified starch, and particularly relates to organic acid glyceride starch and a preparation method and application thereof, and organic acid glyceride starch-starch and a preparation method and application of the organic acid glyceride starch-starch. The organic acid glyceride starch provided by the invention comprises the following raw materials in percentage by mass: 75%-99% of starch, 0.1%-9% of citric acid, 0.01%-14% of glycerol, 0.01%-1.5% of lipase, 0.01%-5% of sodium lactate, 0.01%-0.10% of sodium dehydroacetate and the balance of water. A starch product processed by adding the organic acid glyceride starch provided by the invention into starch is strong in gel strength, good in viscosity breaking performance, long in shelf life, safe, non-toxic and suitable for large-scale production and utilization.

Description

technical field [0001] The invention belongs to the technical field of modified starch, and in particular relates to an organic acid glyceride starch and its preparation method and application, organic acid glyceride starch-starch and its preparation method and application. Background technique [0002] Bean jelly, cold noodle, peeled skin, vermicelli, vermicelli and rice cold noodle are starch processed foods that have been loved by people in recent years, and the industry of such starch products has broad prospects for development. However, there are still some problems in the processing of these starch products, such as insufficient chewiness and poor breaking viscosity of starch products; fresh and wet starch products have a short shelf life, and the shelf life cannot meet industrial production. [0003] In order to solve the problem of insufficient chewiness and poor breaking viscosity of starch products, people mainly solve it by adding alum, and at the same time, alum...
