Description

Technical Field

[0001] The invention relates to the technical field of fruit preservation, and in particular to a method applicable to a smart vending cabinet to extend the optimal edible period of high-sweetness bananas. Background Art

[0002] Banana is a large perennial herbaceous fruit tree of the Musaceae family. Almost all cultivated bananas in the world today are wild banana species: the natural hybridization or natural mutation of the pointed-bristled banana or Ajia banana (Musa acuminata, Calla) and the long-stemmed banana or Lun A banana (Musa balbisiana, Calla) and then evolved through artificial selection. Banana is the best-evolved fruit among all fruit tree species. It is naturally seedless, sweet, rich in nutrients, and can bloom and bear fruit without very high cultivation technology. It has a stable and high yield. It can not only satisfy hunger, but also help digestion and maintain health. It is a cheap and high-quality fruit suitable for everyone.

[0003] Banana is an important fruit and food crop in the world. The main banana producing areas in the world are distributed within the range of 22° north and south latitude, and 130 countries and regions in the world produce bananas. In 2014, the total output of bananas (including plantains) in the world reached 144.8 million tons, ranking first among fruits; in 2022, China's banana output was 11.66 million tons, ranking fifth among Chinese fruits.

[0004] Banana is one of the fruits with the best combination of sweetness and fragrance. The traditional way to eat bananas is to eat them fresh or cooked. 99% of bananas in my country are eaten fresh. Traditional fresh bananas are ripened at 15-24℃, and are sold from green to yellow. The shelf life ends when the bananas start to blossom. In fact, bananas are best eaten when they start to blossom. In ordinary fruit stores, consumers can only buy half-ripe bananas and wait until they are fully ripe before eating them at home. Often, they cannot eat the whole banana at once, which causes waste. Bananas with blossom are treated as defective products. How to get consumers to eat them during the best eating period is a difficult problem. Summary of the invention

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: A method for extending the optimal edible period of high-sweetness bananas applicable to smart vending cabinets, comprising the following steps:

[0006] 1. Use banana varieties with high sweetness and strong fragrance, cut the bananas into small packages of 250-500g, and pick them in the late stage of maturity when they are more yellow than green or both ends are green (i.e. color 4-5);

[0007] 2. Bananas should be harvested as early as possible in the summer when they are fullest. The harvesting process should follow the standard of no damage, and they should be cut, cleaned, sterilized, preserved, air-dried and packaged.

[0008] 3. The present invention requires that both large and small fruits can be sold, and does not require the fruits to be of uniform size, so that people who like bananas can choose the size of bananas by themselves, so that there is no pressure on farm production and procurement due to banana size classification, and the production efficiency is fully improved. Cut and comb as the amount to be eaten at one time, from 0.25-2kg per packaging bag. Single or a group of several can be packaged at will, environmentally friendly and fresh-keeping, special preservative film can keep bananas fresh to the maximum extent, and maintain the peak consumption time for a longer time.

[0009] 4. Depending on the transportation environment conditions, use cold chain transportation or normal temperature transportation to the target market, and it can be put on the market after conventional low-temperature preservation and ripening.

[0010] 5. The packaged ripened bananas are placed in the smart vending cabinet at the later stage of ripening, and raw and ripe bananas are sold separately, with ripe bananas on top and raw bananas on the bottom, and EPP or gourd foam film is placed in the middle to reduce mechanical damage. Raw refers to color 5 with green ends, and ripe refers to color 6 with full yellow. If you like to eat harder bananas, buy raw bananas, and if you like to eat ripe bananas, buy ripe bananas (from color 6 with full yellow to color 7 with plum blossom dots or even large plum blossom dots). Plum blossom bananas are the peak period of starch conversion to fructose, and the soluble solids and aroma are also the highest. The present invention provides a method for extending the optimal edible period of high-sweetness bananas suitable for smart vending cabinets, which can enable customers to eat bananas when they are the sweetest.
