Embodiment 1

[0058] A fresh-cut fruit fresh-keeping agent, the composition ratio (by weight and number of parts) is sodium bicarbonate: water 1:100, and the fresh-cut material is apples.

[0059] The specific usage method is as follows: Dissolve each component in water in sequence according to the composition ratio, and mix to form a mixed solution. When using, soak the freshly cut apple slices in the solution for 5 minutes, take them out with a colander, put them in a fruit and vegetable dryer and shake them for 8-10 turns, then pack them in a polypropylene fresh-keeping box and store them at 4°C .

[0060] The effect of apple slice storage see Picture 1-1 , the cut surface of apple slices treated with this kind of preservative has slight browning.

[0061] The preservative can prevent fruit slices from browning, maintain the crispness (hardness) of slices, and inhibit mildew.

Embodiment 2

[0063] A fresh-cut fruit preservation agent, the composition ratio (by mass and number of parts) is sodium bicarbonate: water 5:100.

[0064] Concrete use method is identical with embodiment 1.

[0065] The effect of apple slice storage see Figure 1-2 , the cut surface of apple slices treated with this kind of preservative has slight browning.

[0066] The antistaling agent can prevent fruit slices from browning, maintain the crispness of slices, inhibit mildew, maintain fruit flavor, and prolong the edible shelf life.

Embodiment 3

[0068] A fresh-cut fruit preservation agent, the composition ratio (by mass and number) is sodium bicarbonate: polyoxyethylene (20) sorbitan monostearate: ascorbic acid: water = 1:0.01:1:100 , the fresh-cut material is apples.

[0069] Concrete use method is identical with embodiment 1.

[0070] The effect of apple slice storage see Figure 1-3 , the apple slices treated with this kind of preservative have slight dehydration.

[0071] The preservative can prevent apple slices from browning, maintain crispness of slices, inhibit mildew, maintain fruit flavor, and prolong edible shelf life.

Abstract

The invention belongs to the field of fresh-cut fruit fresh keeping and particularly relates to a fresh-cut fruit preservative. The preservative mainly comprises the components in parts by weight: 0-5 parts of alkaline preparation and 100 parts of water and further comprises one or more selected from the following components in parts by weight: 0-0.1 part of surfactant, 0-0.1 part of thickening agent, 0-10 parts of humectant and 0-5 parts of antioxidant. The fresh-cut fruit preservative has the advantages of favorably solving the problems of brown stain, discoloration, excessively fast softening, section drying, quality reduction, flavor loss, mildew, pollution and the like of fresh-cut fruits, and prolonging the eating guarantee period of the fresh-cut fruits.

Description

technical field [0001] The invention belongs to the field of fresh-cut fruit preservation, in particular to a fresh-cut fruit preservation agent. Background technique [0002] Fresh-cut fruits, also known as minimally processed fruits and vegetables or lightly processed fruits, etc., refer to fresh fruits as raw materials, after a series of treatments such as grading, cleaning, trimming, peeling, cutting, fresh-keeping, packaging, etc., and then transported at low temperature.
