The tender corn and tender peanuts that have not yet been basically matured are boiled with their delicious flavor and special taste. Nowadays, this kind of natural snack that can only be listed in the autumn harvest season will occasionally appear in food stalls and beer houses in some towns. Although it is expensive, it is very appetizing. This is in addition to a small number of protected areas for off-season cultivation, and most of them are high-cost, low-temperature, quick-freezing, fresh-keeping products.
A new method of using fresh sand and edible preservatives to freshly store tender corn and tender peanuts at room temperature is introduced. The cost of a few cents per pound of tender fruit can be safely stored for several months or even more than half a year. The same taste, color and fresh harvest, can increase the effectiveness of 2-3 times.
Preservation agent preparation: According to the principle of production and marketing of green and pollution-free agricultural products, preservatives are recommended to use a 0.5% aqueous solution of polysaccharides. Glycosan is a kind of white crystalline powder prepared by acid hydrolysis of edible plants such as Ganzi and seaweed. Its aqueous solution has various effects such as insect repellent and antiseptic, which can effectively prolong the preservation period of fruits and vegetables at room temperature. First, the polysaccharide was dissolved in water and formulated into a 5% aqueous solution. When it was used, it was added with boiling water to prepare a 0.5% aqueous solution.
Preservation of tender corn: fresh and corn kernels with moderate tender kernels, preserved 1-2 layers of endothelium (not suitable for bare kernels), placed in a 0.5% aqueous solution of polysaccharides, immersed for 5 to 10 minutes, and removed Drain the water. If the temperature during harvest is higher than 18°C, a layer of corn ear and a layer of fine sand storage method can be adopted to solve the problem of heat and mildew of tender corn through the endothermic action of fine sand. If the tender corn harvested in late autumn can be directly stored in a room with good air circulation and no direct sunlight, a 30-40 cm high ventilation tunnel can be used on the ground before storage, and then the treated corn ear can be placed on it. Above can be. It is worth noting that the ear of corn harvested on that day must be stored on the same day to prevent dehydration, dryness, and aging of the grain by the action of biological enzymes.
Fresh peanut preservation: Fresh peanuts are one of the most difficult agricultural products to store at room temperature. There are two main types of fresh and ripe preservation methods at home and abroad. One is the use of cold storage at low temperature, and the other is vacuum packaging after precooking. The former invests. Larger and the latter is cumbersome, and it is not suitable for the production of one simple household product in China's flower production area. The method of assisting in sand preservation by fresh-keeping agents invented by the farmers in Luxi has undoubtedly found a way to increase the income of farm peanuts. New approach. Dry the fine sand with a 0.5% aqueous solution of polyisocyanide and mix it to a moisture content of 30% to 40%. After the fresh peanuts that have just been excavated have been removed and rooted, a layer of peanuts and a layer of peanuts are freshly stored at a ratio of 1 cubic meter of fine sand per 0.5 mu of product. No manual management such as temperature control and humidity control is required.

In order to improve the quality of catheter care, the fixation of various types of catheters plays an important role in modern nursing. The SEALCUFF Disposable Drainage Tube Holder has the advantages of non-invasive fixation, relieved patient suffering, firm fixation, less allergic reaction, and reduced nurse workload.
