Simple preservation techniques for oyster mushrooms help you extend storage time
Under normal conditions, oyster mushrooms are difficult to store and have a short shelf life. Two days after harvesting, oyster mushrooms lose freshness sharply due to water loss, the caps turn yellow, and an off-odor appears. During peak fruiting seasons, large quantities of fresh mushrooms flood the market at once, causing mushroom prices to plummet; on the other hand, during off-seasons and in cities far from mushroom-growing areas, there is little mushroom supply and nothing to sell. For this reason, here is a brief introduction to research on oyster mushroom storage and preservation. Method: Harvest oyster mushrooms at 80% maturity, remove diseased, insect-damaged, and damaged mushrooms, place them in a clean, cool, ventilated area, and use an exhaust fan for 1-1.5 days of air-cooling pretreatment, then

A Detailed Guide to Jujube Fruit Storage Methods: Easily Extend the Fresh-Keeping Period
I. Timely Harvesting Jujube fruit maturity is one of the important factors affecting the fresh-keeping effect of fresh jujube storage. Many studies have shown that jujube fruit maturity is negatively correlated with storage performance: the lower the maturity, the more storage-tolerant it is, and its storage tolerance declines with jujube fruit maturity. White-ripe fruit is better than early-red fruit, early-red fruit is better than half-red fruit, and the storage tolerance of fully red jujube fruit declines noticeably. In 1985, the storage performance at different harvest times at the Fruit Tree Research Institute of the Shanxi Academy of Agricultural Sciences showed that for pointed jujubes picked from the same tree at different maturity stages and stored in a cold store at 0°C±1°C

What methods are there to extend the storage and freshness period of fresh-eating jujubes?
Jujubes contain a variety of trace elements and abundant nutrients, and have unique nutritional and medicinal value. However, after fresh jujubes are harvested and stored under natural conditions, they have only a few days of crisp freshness, and the flesh quickly turns brown and softens. After several years of experimental research, the author believes that to extend the storage and freshness period of fresh-eating jujubes, the following key techniques must be grasped: 1. Select storage-tolerant varieties. Generally speaking, late-maturing varieties are more storage-tolerant than early-maturing varieties, and dual-purpose varieties have better storage tolerance than fresh-eating varieties. At present, the quality and storage tolerance of Dongzao among fresh-eating jujubes

How to Keep Mutton Fresh: Practical Methods to Extend Its Shelf Life
Fresh mutton, especially a freshly slaughtered carcass, has a suitable temperature and is rich in nutrients, making it ideal for bacterial growth and reproduction. Particularly in hot weather and seasons, under natural conditions it will spoil and deteriorate within a few hours, and sometimes it even begins to discolor and spoil before it reaches the market or is sold out. Given this situation, freshly slaughtered mutton, whether for short-term storage or for slaughter-to-order sales, must be cooled or refrigerated promptly so that the meat temperature drops below 5°C in time, in order to reduce bacterial contamination and extend its shelf life.

Practical methods to extend the fruiting period of tomatoes
After the first generation of tomatoes is harvested, the following 3 methods can be used to make the tomatoes bloom and bear fruit again, improving economic returns. The vine-laying method: after the first generation of tomatoes is mature and harvested, cut off the dead branches and yellow leaves, keep the new branches with vigorous regrowth ability, and dig a fertilization trench 20 cm long and 15 cm deep on one side of the main stem and apply fertilizer. After fertilizing, bury the main stem in the trench and water it, so that the layered vine quickly takes root. In this way, the new roots and old roots absorb water and nutrients together, the plant shape grows rapidly, and the tomatoes can bloom and bear fruit again. The stem-cutting method: after the first generation of tomatoes is harvested, cut off

How should peaches be stored to extend their fresh, crisp period?
Prompt pre-cooling to prevent softening. Because the temperature is relatively high when peaches are harvested, especially for mid- and late-season varieties, if they are not pre-cooled promptly, the peaches will quickly soften, age, rot, and deteriorate. Therefore, after harvest, peaches should be pre-cooled to below 4°C as soon as possible. Generally, two pre-cooling methods are used: forced-air cooling and water cooling. Water cooling is fast: a peach with a diameter of 7.6 cm cooled in 1.6°C water for 30 minutes can have its temperature lowered from 32°C to 4°C. After water cooling, let the fruit dry before packing. Air cooling is slower and generally requires 8-12 hours or longer. Storage

Many Methods for Preserving Edible Mushrooms: Master the Techniques to Extend Storage Life
Salt preservation: Freshly harvested oyster mushrooms, Phoenix-tail mushrooms and the like, after being cleaned up, are soaked in 0.6% salt water for about 10 minutes, then taken out, drained and stored in plastic bags, keeping fresh for 5-8 days. Rice-water film preservation: Add 1% soda ash or 5% baking soda to rice water, stir well, and cool to room temperature. Soak freshly picked mushrooms in the rice water, take them out after 5 minutes, and dry them in a cool, dry place; by then a thin film of rice water will form on the surface of the mushrooms, which can isolate air, and the mushrooms can generally keep fresh for 2-3 days. Ascorbic acid solution preservation

How to store pears in spring? Four methods to help you extend their shelf life
1. Chemical fumigation method. The fumigation method mainly prevents and controls diseases that invade the fruit. First, seal the pears with plastic film, then place a fumigant (such as acetaldehyde) inside the sealed plastic film so that the fumigant concentration inside the plastic film reaches 0.5% and is maintained for 180 minutes, or so that the fumigant concentration inside the plastic film reaches 1% and is maintained for 120 minutes. 2. Medicinal solution soaking method. This method mainly prevents pears from being infected by pathogens after harvest. Soak the pears in a 400-fold dilution of 4% Nongkang 120 fruit tree-specific solution for 50 minutes, then remove and air-dry, then package and store

How to extend the flowering period of pansies? These methods are very practical
There are two main ways to extend the flowering period of pansies: 1. Use different sowing times: pansies generally bloom about 2 months after sowing, so sowing in spring means blooming from June to September, sowing in summer means blooming from September to October, sowing in autumn means blooming in December
