In the past few weeks, the weather in Hangzhou was difficult to understand. When I was cold, I couldn't wait to wrap myself in a quilt. When I was hot, I was left in the summer. When it comes to summer, the most unforgettable thing is the watermelon, but the fig. In the elementary school, when I was returning home from school, there was a fig tree on the roadside. At that time, the only thing I had to do at school was to drill under the tree and look for the one that was full of redness. It was also when I knew that figs were mature and I wanted to pick them up completely. It's very difficult and it can't be stored for long-term use. 'It would be nice to have this kind of fruit all year round. 'It's always a fantasy when you're young. You grow up to enjoy it all year round. Fig is not an unattainable fantasy. It can be achieved through food machinery and equipment.
In fact, mature figs are stored at room temperature for no more than 24 hours. Low temperatures can extend the shelf life of foods, so cold storage plays an important role in extending the shelf life of figs. However, cold storage is not a solution once and for all. People find that cold storage is a permanent solution. Unsuitable temperature will degrade the fruit quality of figs and eventually affect the taste. A cooperative in Weihai, Shandong Province, through repeated consultations with experts in agricultural sciences and repeated trials, has finally found the optimal temperature for fig refrigerated storage, which can store figs fresh fruit. The time changes from one day to one week, the appearance of figs, the flavor will not have much difference with the fresh fruit.
It is also a common practice in the industry to allow fruit to be stored for a long period of time. Traditional drying, drying, and drying will cause certain loss of nutrients in figs. The vacuum freeze-dried fruits that are popular in the market can avoid the production of dry fruits. The loss of nutritional value. Vacuum freeze dryers are used in the process. The device freezes the figs in a low temperature environment and then sublimes them in a vacuum. After the dried figs are dried, the figs are not damaged. The original shape can also retain nutrients. However, the use of a vacuum freeze-dryer requires high quality of fig fruits, which cannot be achieved at all. This imposes certain requirements on fig separation equipment. According to the author's understanding, there is no present Specifically for the fig sorting equipment, the R&D and production units of related sorting equipment can seize the opportunity to develop a sufficiently gentle and appropriate equipment to sort the figs.
As a kind of fruit, figs are exposed to pesticides when they are planted. This kind of natural elimination of pesticide residues meets people's needs for healthy foods. Together with the dozens of nutrients contained in figs, it makes them in deep processing. There is also great potential. China's export of fig deep-processing products has improved in recent years, but product varieties are limited to dried fruit, canned food, preserved fruit, fruit juice, fruit powder and other products, but have a certain added value but not high enough, and the degree of deep processing is limited.
To solve this problem, we need to start from two aspects. First, fig deep-processing companies research and develop fig deep-processing technology. For example, a company in Henan intends to cooperate with universities like China University of Science and Technology and Henan University of Science and Technology to fully develop the medicinal and food value of figs. , Research and production of fig edible agents, medicinal agents and other products. In Weiyuan County where the fig industry is more mature, Jin Sifang Fruit Industry introduced German equipment for the production of fig fiber rods, allowing figs to enter the field of meal replacement bars. Science and technology has established R&D centers in research institutes such as joint universities and research institutes, developed the first fig enzyme, and introduced the fig puree production line to standardize enzyme production...
The second is in-depth research and development of deep-processing fig production equipment. From the above analysis, we know that at present, China's food processing machinery related to deep processing of figs still remain in the relatively early stage. Like dried fruit, canned food, juice and other products have been produced accordingly Food machinery and equipment, but for research and development of fig production fiber rods, enzymes and deep processing products such as enzymes, related companies still need to import from abroad. Therefore, China's food machinery and equipment companies need to further research and development of equipment to promote the fig. Deep processing development.
