[0046] A preparation method of litchi gas preservative, comprising the following steps:

[0047] S1: After micronizing 7 parts of garlic extract and 4 parts of orange peel extract to a particle size of 10 μm, add 7 parts of garlic extract and 4 parts of orange peel extract into a relatively airtight container and stir to mix evenly. The stirring time is 3 minutes, the stirring speed is 20 rpm to 30 rpm, and the first mixture is obtained;

[0048] S2: First micronize 15 parts of pullulan and 11 parts of noni fruit extract to a particle size of 10-15 μm, then mix 15 parts of pullulan, 11 parts of lycopene and 11 parts of noni The fruit extracts are sequentially added into another relatively airtight container for stirring, the stirring time is 5 to 10 minutes, and the stirring speed is 20 rpm to 30 rpm to obtain the second mixture;

[0049]S3: Add the second mixture to the first mixture, and finally add 15 parts of nano-chitosan and 13 parts of sodium peroxide to prepare the ra...

Embodiment 3

[0067] A preparation method of litchi gas preservative, comprising the following steps:

[0068] S1: After micronizing 9 parts of garlic extract and 5 parts of orange peel extract to a particle size of 10 μm, add 9 parts of garlic extract and 5 parts of orange peel extract into a relatively airtight container and stir to mix evenly. The stirring time is 3 minutes, the stirring speed is 20 rpm to 30 rpm, and the first mixture is obtained;

[0069] S2: First micronize 20 parts of pullulan and 15 parts of noni fruit extract to a particle size of 10-15 μm, then mix 20 parts of pullulan, 15 parts of lycopene and 15 parts of noni The fruit extracts are sequentially added into another relatively airtight container for stirring, the stirring time is 5 to 10 minutes, and the stirring speed is 20 rpm to 30 rpm to obtain the second mixture;

[0070] S3: Add the second mixture to the first mixture, and finally add 20 parts of nano-chitosan and 15 parts of sodium peroxide to prepare the r...

Abstract

The invention discloses a litchi gas preservative as well as a preparation method and a use method thereof. The litchi gas preservative comprises the following components: sodium peroxide, pullulan, lycopene, a morinda citrifolia extract, a garlic extract, an orange peel extract and nano chitosan. During preparation, the garlic extract and the orange peel extract are mixed, the pullulan, the lycopene and the morinda citrifolia fruit extract are sequentially added into another relatively closed container to be stirred and mixed, the two are mixed, finally, the nano chitosan and the sodium peroxide are added, the litchi gas preservative is sprayed on litchis, water is uniformly sprayed on the litchis, and the litchis are dried. The lychee fruit preservative can form a layer of compact protective film on the outer surface of lychee fruits, can play a role in inhibiting bacteria on the peels of the lychee fruits and inhibiting the respiration of the lychee fruits, has good water resistance, avoids water loss, can form a gas-phase protective layer around the outer layer of the protective film, and plays an effective role in inhibiting bacteria and preserving moisture; therefore, the purpose of preserving freshness is achieved.

Description

technical field [0001] The invention relates to the technical field of antistaling agents, in particular to a litchi gas antistaling agent and its preparation method and application method. Background technique [0002] Lychee tastes sweet, sour, warm in nature, enters the heart, spleen, and liver meridian; it can stop hiccups and diarrhea, and has the effects of nourishing the brain and fitness, appetizing spleen and promoting appetite. It is deeply loved by people, so people's demand for lychee It is also increasing. [0003] There are cracks on the surface of litchi fruit, and the pericarp is composed of inner, middle and outer layers. The outermost layer is palisade-like histiocytes containing anthocyanins, with a lot of tissue pores; the middle layer is a spongy tissue with huge intercellular spaces. , accounting for most of the pericarp; and the innermost layer is several layers of denser parenchyma cells. There are stone cells between the exocarp and mesocarp, conta...
