Freeze-dried fruit into powder will not affect its nutrition. Normally heat-sensitive substances are lost at high temperatures. For example: traditional high temperature drying technology. Freeze-drying technology and sun drying, drying, spray drying and so on are drying technologies, different drying methods have different effects on the quality of products. Freeze-drying method has less damage to the product. The traditional drying method is above 0℃, while the freeze-drying technology is simply understood to sublimate the moisture of fresh food under the vacuum and low temperature environment, and retain its original nutritional composition, appearance, size and other biological characteristics.

Foshan, Guangdong, Practically Doing Well the Prevention and Control of Pests and Diseases of Guagua Vegetables
At present, the melons, watermelons, cucumbers, loofahs, and melons, and other melons, are growing from the vegetative stage to the harvesting stage. They are also affected by blight, epidemics, downy mildew, virus diseases, whiteflies and fleas. The main period of time. With the increase of temperature and the increase of rainfall, it is easy to induce the occurrence and prevalence of many kinds of pests, and it has great influence on the production of wax gourd and other vegetables. Must pay close attention to all localities. From April 8th to April 16th in Foshan, Guangdong Province, surveys were conducted in Guanyao, Heshun, Shishan, Sanshui Datang, and Leping towns in Nanhai. The average incidence of Fusarium wilt and quince wilt disease was 6-12. %, the serious fields are 40-70%; the incidence of the disease is generally 3-8% for field plots, 15-35% for severe plots; the incidence of virus disease is generally 5-10% for plots, severe fields The block is 20-30%. The whitefly hopper of Bemisia tabaci is generally 200-450 heads, and the height is 600-1000 heads. The larvae of the larvae are generally 250-600 heads and the height is 650-1000 heads. Gaoming station from April 11 to 15 investigation, the average sick leaf rate of cucumber downy mildew rate 66%, disease index 38.89; wilt disease rate of 3-5%; virus disease occurs generally, the general field is 30-60%, Severely 70-80%; Pygmyema argentatus average of 1171, Bemisia tabaci general field block typus insect population 500-600 head, more than 1,000 serious. This year is a year when the occurrence of pests and diseases is heavy. If it is not controlled in time, it poses a great threat to vegetable production. Therefore, plant protection agencies around the country must strengthen technical guidance and mobilization efforts to effectively tackle the current prevention and control of pests and diseases of melons. Prevention and control opinions: 1. Strengthen the field survey and monitoring, accurately grasp the dynamics of major pests and diseases of various crops, and guide and control the classification. 2. Completely formulate and implement various comprehensive defense measures. Selection of high-yielding, high-impact (resistant) disease-resistant seed varieties; strengthening of fertilizer and water management to create an ecological environment conducive to melon growth and unfavorable to the occurrence of diseases and pests; timely supplemented by chemical control, prevention and control of diseases must be at the beginning of the disease Spraying, spray once every 6-10 days, 2 or 3 times in succession, pest control to catch the young larvae (or nymphs during the peak period) in a timely manner spraying drugs to be used alternately or depending on the incidence of mixed use. 3. Do a good job in the safe use of pesticides in vegetable areas. We will vigorously promote the use of high-efficiency, low-toxic, low-residue pesticides and various types of biological pesticides, and prohibit the use of highly toxic and high-residue pesticides such as methamidophos and carbofuran. The correct application method is adopted, and according to different crops and control objects, a reasonable amount and concentration of pesticides are used, and the dosage and concentration are not arbitrarily increased, so as to avoid causing crop phytotoxicity and pest resistance. Strictly abide by the safety intervals of various pesticides and ensure the quality and safety of vegetable products. Formulations for pharmaceutical control: (1) Control of Bemisia tabaci and puffer horses: Imidacloprid, 2.5% AkeTai, and good year winter sprays are available. (2) Preventing downy mildew and epidemic diseases: It can be used for spraying such as Jinledaomier, B-aluminum, antivirus, Keluo, etc. (3) Fusarium wilt prevention and control: Antibiotic 120, Mancozeb, thiophanate, etc. can be used. Bacteria and other spraying or spray. (4) Prevention and cure of viral diseases: You may choose to use gypoxic gram spray, while doing a good job of aphids, thrips, and whiteflies.
