Embodiment 1

[0024] This embodiment provides a biosolvent for dissolving natamycin with alkaloids, the biosolvent is a compound acidity regulator type I, and the biosolvent consists of 52% of alkaloid solution, 2% of glacial acetic acid, DL - Made of 1% malic acid, 3% lactic acid, and 42% drinking purified water, wherein: the alkaloid solution is made of 30% saponin pod powder, 15% saponin leaf dry powder, and 55% ethanol in terms of mass percentage.

[0025] In this embodiment, the alkaloid is a biological saponin alkali solution prepared from saponin leaves and saponin pods, dried → pulverized (400 mesh) → high temperature soaking (95°C) → ethanol distillation (120 ℃)→The obtained saponin alkali solution→pH>12→dissolved natamycin→completely dissolved→used with alcohol→clear and transparent without suspension→pH value adjusted to 7.0 without reduction→after 75 repeated gradient tests→can still be dissolved Ester food preservatives (such as ethyl p-hydroxybenzoate) have stable results and ...

Embodiment 2

[0028] The difference between this example and Example 1 is that the biosolvent is made of 50% of alkaloid solution, 1% of glacial acetic acid, 1.5% of DL-malic acid, 2.5% of lactic acid, and 45% of drinking purified water according to the mass percentage, wherein: The alkaloid solution is prepared from 30% of saponin pod powder, 10% of saponin leaf dry powder and 60% of ethanol in terms of mass percentage.

Embodiment 3

[0030] The difference between this example and Example 1 is that the biosolvent is made of 55% of alkaloid solution, 2% of glacial acetic acid, 1% of DL-malic acid, 3% of lactic acid, and 42% of pure drinking water according to the mass percentage, wherein: The alkaloid solution is prepared from 25% of saponin pod powder, 20% of saponin leaf dry powder and 55% of ethanol in terms of mass percentage.

Abstract

The invention discloses a biological solvent for dissolving natamycin with alkaloid and application of the biological solvent. The biological solvent is prepared from the following materials by mass percentage: 50-55% of alkaloid solution, 1-3% of glacial acetic acid, 0.5-1.5% of DL-malic acid, 2-4% of lactic acid, and 40-45% of drinking pure water, wherein the alkaloid solution is prepared from the following materials by mass percentage: 25-35% of saponin pod powder, 10-20% of saponin leaf dry powder and 50-60% of ethanol. The above biological solvent can be used for dissolving sodium natamycin and baked food. The biological solvent disclosed by the invention belongs to a type I acidity regulator of compound food, alkaloid, glacial acetic acid, DL-malic acid and lactic acid in the 'Sanitary Standard for the Use of Food Additives' GB2760-2014 and the drinking pure water are adopted as raw materials to be combined into a whole,and the production cost is greatly reduced; the cost of extracting the alkaloid merely from saponin leaves and saponin pods is very expensive, and the problem of high cost is solved by in a compounding way.

Description

technical field [0001] The invention relates to a liquid saponin alkali solvent, which can be used as an acidity regulator for dissolving natamycin. Background technique [0002] Natamycin is an odorless, tasteless, low-dose and highly safe food preservative. It is used in 11 food categories in the "National Food Safety Standards" GB2760-2014. It has obvious effect on food surface fungus. However, food companies have no choice but to use natamycin because it is insoluble in water, and it is difficult to control the residual amount of the suspended liquid on the food surface to <10mg / kg. [0003] In the National Food Additive Manual, natamycin can be dissolved in methanol, which has poor solubility and is in a suspended state, which leads to loss of raw materials and increased cost. Dissolving with dilute hydrochloric acid, dilute lye, glacial acetic acid and dimethylamide has the disadvantages shown in Table 1: [0004] Table 1 [0005] [0006] [0007] In view...
