Description
Technical Field
The invention relates to the technical field of fruit preservation, in particular to novel edible preservative paper and a preparation process thereof.
Background
Fruit refers to a plant fruit that is juicy and has a predominantly sweet and sour taste. The fruit not only contains rich vitamin nutrition, but also can promote digestion. After purchasing fresh fruits, if we store newly purchased apples or bananas in a large fruit basket and even put them in the same part of a refrigerator, the fruits will be ripened quickly, how not to eat them in time in the ripening process, the fruits will be contacted by many bacteria, and the bacteria will infect the fruits, thereby affecting the taste and quality thereof.
Patent number CN201810537201.3 discloses a fruit preservative paper, wherein the mass ratio of chitosan to chitosan is 1: 10-15, adding acetic acid solution, mixing and stirring, standing to obtain chitosan liquid, wherein the mass ratio is 1: 10-15, mixing and stirring sodium alginate and water to obtain sodium alginate solution, wherein the mass ratio of the sodium alginate solution to the water is 1: 1-2, adding gelatin solution, uniformly mixing, carrying out ultrasonic defoaming to obtain mixed solution, and taking the mixed solution according to the mass ratio of 1:0.3: 2-4 adding a cross-linking agent and chitosan solution, mixing and stirring, and standing to obtain a modified chitosan solution for later use; according to the mass ratio of 1:1: 15-20, mixing and stirring zeolite, sepiolite and saturated potassium permanganate solution, heating for 3-5 hours at 100-110 ℃, standing, cooling, filtering, and drying filter residues to obtain pretreated stones; pulverizing and sieving pretreated stones, and taking sieving particles according to the mass ratio of 1:3-5: 2: 7-8 adding the modified chitosan solution, epoxy chloropropane and acetic acid solution which are prepared in the step (1), mixing and stirring at 25-40 ℃ to obtain a mixture, adding NaOH solution with the mass of 5-10% of the mixture into the mixture, mixing and stirring, standing, filtering, cleaning filter residues with water according to the mass ratio of 1:3-5, and drying to obtain a composite modified chitosan component; the patent solves the problem that the fresh-keeping effect is not obvious; however, when the preservative paper is stuck to the outer wall of the fruit under the unexpected condition of the fruit, the preservative paper cannot be directly eaten.
Patent number CN201510248169.3 discloses fruit preservative paper, and preservative solution is prepared from the following raw materials in parts by weight: 10 to 20 parts of myrrh extract, 15 to 25 parts of eucalyptus oil, 5 to 15 parts of loquat leaf extract and 2 to 10 parts of swamp cabbage extract; the preparation method comprises the following steps: coating a layer of starch solution on the base paper, airing, spraying fresh-keeping liquid by adopting a spraying method, transferring into a freeze drying box, adjusting the temperature to be 0-3 ℃, and freeze drying for 5-10 minutes. In the above technical solution, a more specific solution may also be: extracting the myrrh extract, the loquat leaf extract and the herba Salsolae Collinae extract with ethanol; further, the concentration of the starch solution is 80 g/L to 120 g/L. The preservative paper with obvious preservative effect and low cost has great practical value; however, when the preservative paper is stuck to the outer wall of the fruit under the unexpected condition of the fruit, the preservative paper cannot be directly eaten.
In view of this, we propose a novel edible preservative paper and a preparation process thereof.
