5 ways to improve the hardness of strawberry fruit, not look really pity

Post-harvest hardness of strawberry determines the length of storage period of fruit. How to delay the decline of fruit hardness to the maximum extent and extend the shelf life of fresh fruit under the premise of ensuring the quality of strawberry has become an urgent problem to be solved in strawberry production, transportation and sales. So today we're going to talk about the factors that affect strawberry fruit firmness and what you can do about it.
5 influencing factors
1. Japanese varieties have soft fruits
Japanese varieties have good quality and strong fragrance, but poor storage resistance and disease resistance, Hongyan and Zhangji are not resistant to storage and transportation, Zhangji hardness is worse than Hongyan; European and American varieties of strong growth potential, fruit hardness, storage and transportation, but sour, light taste.
From experience, strawberry seeds protruding from the fruit surface tend to be harder, sinking into the pulp is less hard. At present, among the cultivated varieties of strawberry, the hardness of lucky Xiang, sweet Charlie, Mei Xiang Sha and so on.
2. Higher temperatures make fruits softer
Strawberries will be constantly attacked and infected by external bacteria during storage. In the case of high temperature, the reproduction rate of microorganisms is very fast, and the respiration of fruit cells is vigorous, which is also more conducive to microbial reproduction. The nutrients of the fruit are rapidly degraded and the fruit becomes soft.
3. The higher the moisture, the softer the fruit
The water content of strawberry fruit is large, the water content of fresh strawberries is generally 85% to 93%, and the fruit with high water content has low hardness, light color, and is easy to rot and deteriorate, so it has a short shelf life.
4. The later you pick, the softer the fruit
The higher the maturity of strawberries, the lower the hardness, the worse the storage resistance, the appropriate early harvest will help to improve the fruit hardness. But there is also a problem here, too high maturity fruit soft and easy to rot fruit, too low maturity fruit hard flavor.
It is more appropriate to harvest the strawberries with a hardness of seven or eight mature (change color period), and if the strawberry garden needs to be eaten on the same day, the red ripening period (about 75% maturity) is the best harvest period.
5. The less calcium, the softer the fruit
Calcium causes the pectin in the cell wall to form calcium pectin, thereby maintaining the structure of the cell wall. Calcium-treated fruit will harden, and the higher the calcium concentration, the harder the fruit.
5 ways to cope
(1) In addition to hardness, variety selection also needs to consider many aspects, as well as market acceptance, taste, fruit type, etc., so it is still necessary to choose varieties according to a variety of circumstances.
(2) Low temperature refrigeration can inhibit the growth of microorganisms and delay the decline of fruit hardness. If it is long distance, it can be kept at low temperature by cold chain transportation and other methods.
(3) Fruit expansion requires water, so it is recommended to properly control water in the middle and late stages of fruit growth, that is, the middle and late stages of color change before harvesting, and reduce the amount of watering within the appropriate range, which will help to improve hardness and fruit quality.
(4) Timely harvesting, strawberry hardness of 70 or 80 mature (color change period) is more appropriate, if it is to pick the strawberry garden needs to eat on the same day, red ripe period (maturity of about 75%) is the best harvesting period.
(5) Proper calcium supplementation, spraying calcium magnesium borax fertilizer on the leaf surface of the fruit during the expansion period, 1-2 times.
