Since peaches are rich in nutrition and balanced, they are an ideal fruit for human health. Peach is a fruit with high nutritional value, containing protein, fat, sugar, calcium, phosphorus, iron and vitamins B and C. Peach has a high iron content, which is almost the first among fruits, so eating peaches can prevent and treat anemia. Peach is rich in pectin, and regular consumption can prevent constipation. Garden peaches have a unique shape, large and bright (the largest fruit is 300-400 grams), delicate flesh, sweet and delicious, delicious taste, rich in a variety of nutrients, after eating, it can nourish the heart and promote blood circulation, clear heat and nourish the skin, moisturize the intestines and help digestion, and is deeply loved by consumers. Peach bears fruit early and has high yield. Generally, it bears fruit after two years of planting and benefits after three years. It has high yield and stable yield. The fruit matures and is harvested in a concentrated period (August 10-September 5). It is mainly sold as fresh food. The fruit is not resistant to storage and transportation and is prone to browning and rotting. Pantao is rich in nutrition, delicious in flavor and beautiful in appearance, and is praised by people as a fruit of longevity. Potted Pantao not only beautifies the environment, but also blooms in spring and bears fruits in autumn, which has the dual functions of viewing and eating fruits. Generally speaking, Pantao is more nutritious than ordinary peaches.Storage of peachesIt is very difficult to store peaches. Within 2-3 days after harvesting, the flesh softens quickly and turns brown, losing its edible value. In addition, the harvest period is relatively concentrated. Every July and August, a large number of fresh peaches flood into the market, which is difficult to sell, causing a sharp drop in prices. Those that cannot be sold will rot and pollute the environment. Therefore, solving the storage problem of peaches, avoiding the peak of post-harvest listing, extending the market supply period, and increasing its output value are urgent issues to be solved in the production and operation of peaches. 1. Reasons why peaches are difficult to store 1.1 Pantao is a respiratory climacteric fruit. At room temperature, the respiration intensity is high and the respiration peak comes quickly, so the fruit tends to age quickly. However, under low temperature conditions (0-5℃), the respiration of Pantao becomes very slow and the inhibitory effect is more obvious. According to measurements, Pantao has two respiration peaks during the 40-50 days of cold storage after harvest. When the first respiration peak arrives, the flesh begins to soften; after the second respiration peak arrives, the flesh first starts to turn brown from the vascular bundle, and then the entire flesh turns brown. 1.2 At room temperature, the physiological mechanism of fruit softening and browning is that the activity of fruit enzymes is very active, especially the rapid increase in the activity of pectin decomposing enzymes, cellulases, polyphenol oxidases, peroxidases and peroxidases, which promotes the softening of the flesh. As the fruit ages, the speed of enzymatic browning accelerates, causing the flesh to become browner. |
