Embodiment 1

[0023] A novel fruit and vegetable fresh-keeping liquid, the composition and ingredients in the fresh-keeping liquid are as follows: the mass fraction is 0.5% lotus pod polyphenols and the volume fraction is 1.5 µL / L methane, and the balance is water. The preparation method of the new fruit and vegetable fresh-keeping liquid, 1) prepare the lotus pod polyphenol solution with a mass fraction of 0.5% with water; 2) connect the plastic air pipe with a diameter of 0.4cm to the air stone, and then place the air stone in step 1) 3) Add pure methane gas so that the volume fraction of methane in the solution is 1.5µL / L, and a new fruit and vegetable fresh-keeping solution can be obtained.

Embodiment 2

[0025] Novel fruit and vegetable fresh-keeping liquid, the composition and ingredients in the fresh-keeping liquid are as follows: the mass fraction is 2.0% lotus pod polyphenols and the volume fraction is 5 µL / L methane, and the balance is water. The preparation method of the new fruit and vegetable fresh-keeping liquid, 1) prepare the lotus pod polyphenol solution with a mass fraction of 2.0% with water; 2) connect the plastic air pipe with a diameter of 0.4cm to the air stone, and then place the air stone in step 1) 3) Add pure methane gas so that the volume fraction of methane in the solution is 5µL / L, and a new fruit and vegetable fresh-keeping solution can be obtained.

Embodiment 3

[0027] Novel fresh-keeping liquid for fruits and vegetables, the composition and ingredients in the fresh-keeping liquid are as follows: the mass fraction is 1.0% lotus pod polyphenols and the volume fraction is 3 µL / L methane, and the balance is water. The preparation method of the new fruit and vegetable fresh-keeping liquid, 1) prepare the lotus pod polyphenol solution with a mass fraction of 1.0% with water; 2) connect the plastic air pipe with a diameter of 0.4cm to the air stone, and then place the air stone in step 1) 3) Add pure methane gas so that the volume fraction of methane in the solution is 3µL / L, and a new fruit and vegetable fresh-keeping solution can be obtained.

Abstract

The invention discloses a novel fruit and vegetable fresh-keeping agent which comprises the following ingredients: 0.5-2.0 wt% of lotus seedpod polyphenol, 1-5 microliters / L (by volume) of methane and the rest of water. A preparation method of the novel fruit and vegetable fresh-keeping agent comprises the following steps: 1) using water to prepare 0.5-2.0 wt% of a lotus seedpod polyphenol solution; 2) connecting a plastic air-pipe and air stone, putting air stone into the lotus seedpod polyphenol solution prepared in the step 1); and 3) introducing pure methane gas until the volume fraction of methane in the solution is 1-5 microliters / L, so as to obtain the novel fruit and vegetable fresh-keeping agent. By the technical scheme, aging process of postharvest fruits and vegetables can be slowed down, and resistance and storability of postharvest fruits and vegetables are enhanced.

Description

technical field [0001] The invention relates to a fresh-keeping liquid, in particular to a novel fruit and vegetable fresh-keeping liquid, a preparation method of the fresh-keeping liquid and an application thereof, and belongs to the technical field of agricultural product preservation methods. Background technique [0002] Fruits and vegetables contain a variety of nutrients, which have comprehensive physiological and nutritional functions for the human body. They are easily digested, absorbed and utilized. They can regulate human metabolism, enhance physiological functions and immunity, and cannot be replaced by other foods. However, after fruits and vegetables are harvested, they are separated from the original growth environment and the mother plant, and lose the supply source of water and nutrients, but their life activities do not stop because of this. Fruits and vegetables still undergo a series of physiological and biochemical activities during postharvest circulati...
