Abstract
This invention pertains a kind of technique for preserving loquats, which dissolved the defect of loquat' hard preserving. It can preserve loquats over 35 days, keeping good quantity, over 95% goodness. The invention controls maturity, cool first, preserving at low temperature. It offers a set of technique, the quantity of MAP for a month is equivalent to the quantity of generous preserving for 15 days. Apply this technical preserving 35 days, over 95% good fruit, including acid over 0.20%, solid over 9.0%; After 43 days, also having good quantity. Using the technique, low cost, easy operation, technique advanced, applies long way preserving.
Description
(1) technical field:
The present invention relates to a kind of MAP fresh-keeping technology of fruit, especially relate to a kind of loquat MAP fresh-keeping technology.
(2) background technology:
Loquat is China's special product fruit, accounts for 2/3 of world wide production, and is ripe early summer, the sweet acid appropriateness of fruit, and unique flavor is loved by the people, and extensive market is promising greatly.But the loquat pericarp is thin, is mechanically damaged easily in gathering and transporting and brown stain occurs, rot.Along with the prolongation of adopting the back time, because of physiological action, its sugar, acid content sharply descend, the quality step-down simultaneously; And during cryopreservation, pericarp and pulp adhesion also can occur, be difficult to peel off, lignifying that the soft and succulency of pulp before by storage becomes stiff, the coarse few juice of quality ruins phenomenon.Do not see the application of studying in report and the production with MAP fresh-keeping loquat.
(3) summary of the invention:
The invention solves the unfavorable defective of existing loquat preservation technique fresh-keeping effect, a kind of good refreshing effect, the time is long, cost is low loquat modified-atmosphere package (MAP) preservation technique are provided.
Technical scheme of the present invention is as follows: by the fresh-keeping loquat is carried out in the control of loquat harvest maturity, reserve temperature and thin-film material, thickness and suitable ventilative area.Its fresh-keeping step is as follows: loquat fresh fruit packing, precooling, blister-pack, refrigeration or storing, sale.
Advantage of the present invention is as follows:
1, loquat is fresh-keeping 35 days, and good fruit rate contains acid＞0.20%, soluble solid＞9.0% more than 95%; Preserve and still have quality preferably after 43 days; The main quality that loquat MAP is fresh-keeping one month is suitable with 15 days quality of conventional preservation by low temperature.Can obviously suppress decline sugared, sour in the fruit, improve the commodity value of fruit.
2, the fresh-keeping cost of loquat MAP is low, easy and simple to handle, and technical application, advanced person can be applicable to the long-range storing of loquat.
(4) specific embodiment:
Main technique flow process of the present invention is as follows:
Loquat fresh fruit → classification → packing → precooling → blister-pack → refrigerate or store and transport → rise again → sell.
Major technique:
1. raw material: with ninety percent ripe above healthy loquat fresh fruit is raw material, reject hinder fruit, base of a fruit fruit and disease and pest fruit fall;
2. pack: with frame of plastic packing loquat, every frame 9～10kg;
3. fruit is 4～8 ℃ of following precoolings after 12～24 hours;
4. the suitable ventilative area with every kg loquat is 0.16～0.28m
2The thick PE film of 0.02～0.03mm to above-mentioned frame of plastic packing;
5. refrigeration or the storing temperature: 6-10 ℃;
Embodiment 1:
Is the frame of plastic packing of 50 * 34 * 16 (cm) with 100kg ninety percent ripe above loquat fresh fruit with length * wide * height, and 10 kilograms of every frames after precooling in 24 hours, are packed frame of plastic with the PE film bag that 0.02mm is thick, are 1.56m at ventilative area
2The place tightens sack or heat sealing.Be put into and preserve or store and transport sale under 6-10 ℃.
