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.
