Embodiment 1

[0011] Embodiment 1, a kind of fruit preservatives such as lychee, apple, pear, is characterized in that by being able to decompose the oxyacid salt of sulfur dioxide and auxiliary agent to process as raw material ratio; Raw material takes following weight percent: oxyacid Salt 70%, and additives 30%.

[0012] The aforementioned fruit fresh-keeping agent for lychees, apples, pears, etc. is characterized in that: the oxygen-containing salt is selected from three mixtures of sodium sulfite, sodium bisulfite, and sodium thiosulfate.

[0013] A kind of antistaling agent for fruits such as lychees, apples and pears mentioned above is characterized in that: the auxiliary agent is selected from three kinds of mixtures in starch, gelatin and propionic acid.

Embodiment 2

[0014] Embodiment 2, a kind of fruit preservatives such as lychee, apple, pear, it is characterized in that by being able to decompose the oxyacid salt of sulfur dioxide and auxiliary agent to process as raw material proportioning; Raw material adopts following weight percent: oxyacid Salt 50%, and additives 50%.

[0015] The aforementioned fresh-keeping agent for lychees, apples, pears and other fruits is characterized in that: the oxyacid salt is selected from the mixture of sodium pyrosulfate and potassium oxyacid and calcium salt.

[0016] A kind of antistaling agent for fruits such as lychees, apples, and pears mentioned above is characterized in that: the auxiliary agent is selected from five kinds of mixtures of propionic acid, citric acid, sorbic acid, calcium oxide, calcium peroxide, and potassium permanganate mixture.

[0017] The beneficial effect of the preservative for lychees, apples, pears and other fruits of the present invention is that the lychees, apples, p...

Abstract

The invention provides a fruit preservative for lychee, apple, pear and so on. The preservative is produced by raw materials comprising 30-70% of oxysalt which can be decomposed into sulphur dioxide and 30-70% of additive by weight. The fruit processed according to the invention has long fresh-keeping period and rich flavor, and is suitable for fruit food or drink as materials. The fruit, which is processed for a certain soak period according to the invention, can keep fresh for 5-6 days in ventilating conditions at normal temperature. Because the oxysalt which can be decomposed into sulphur dioxide is added to adjust osmotic pressure of pulp and play mildew-resistant and corrosion-resistant function, the shelf life of fresh fruit is greatly prolonged; and there's no harmful substance on the fruit peel.

Description

1. Technical field [0001] The invention relates to a fruit fresh-keeping agent, in particular to a fruit fresh-keeping agent suitable for short-term storage and long-distance transportation of litchi, apple, pear and other fruits. 2. Background technology [0002] Fruits such as lychees, apples, pears are rarely liked by people as seasonal fruits, but the fresh-keeping period of fruits such as lychees, apples, pears is very short. Litchi, apples, pears and other fruits are generally harvested in summer and autumn, and are shipped and sold to provinces and cities across the country that do not have lychees, apples, pears and other fruits. However, for a long time, the storage and long-distance transportation of lychees, apples, pears and other fruits have been carried out under natural temperature conditions. Under these conditions, it will rot and deteriorate in a few days, thus causing a lot of losses. [0003] Existing fruit fresh-keeping technologies such as lychees, ap...
