Okra shaped like chilli was first introduced into China as a health food, but okra has not escaped the turmoil of demand brought about by changes in market supply and demand. The phenomenon of 'high yield is not good' still plagues growers. For this reason, deep processing has become an autumn. Another avenue of the development of the Kwai industry, with the deepening of the nutritional value of okra by the Chinese people, okra is gradually processed into various types of foods and health products, which greatly enhances its nutritional value.
Okra processed foods
Okra grows very fast and has a long picking period. After entering the picking period, it basically maintains the state of daily flowering. This results in sufficient supply of okra for deep processing. It is reported that Zhengzhou, Anhui, and Yunnan are currently digging autumn. The value of Kwai deep-processed into food is processed into a variety of products such as dried vegetables, tea, biscuits, noodles, beverages, wine, oil, etc. These products are not only popular in China, but also exported to South Korea, Japan, Myanmar and other places. .
For vegetables such as dried vegetables, tea, biscuits, etc., okra needs to be dehydrated and dried, but the requirements for dehydration and drying are not the same. The finished product is a vegetable that needs to retain its texture and its maximum in the drying process. Active nutrients, vacuum freeze-drying equipment currently available on the market meets this requirement, using ice water to sublimate directly to achieve drying, but also to maintain the original shape to the maximum. When the okra is made into tea, the fixing equipment can play a certain drying effect. At present, most of the fixing devices use rollers to keep green, avoiding the high temperature adhesion due to continuous rolling.
Okra is also very economical due to its rich nutritional value. It is a huge economic benefit to produce okra oil. In order to protect the integrity of nutrients in okra oil, okra is usually used in the oil production process. As a result, okra has a low oil yield and cannot be produced efficiently. For this reason, experts have continued to practice it. Through two presses, seven professional deep purifications and vacuum decolorization and deodorization technologies have improved the yield of okra oil. But even so, peanut oil The oil yield is still more than three times that of okra oil.
Extraction of Nutrients for Deep Digging of Okra Health Value
Earlier, there was an authoritative body in China to test the nutritional value of okra. The test results showed that okra contains flavonoids, chlorogenic acid, polysaccharides and other nutrients and minerals. It is a nutrient-rich pure natural health vegetable. In the face of this test result, many companies have developed okra deep processing to develop corresponding health products.
During the long-term cultivation practice, it was found that the okra contains more flavonoids and chlorogenic acids than okra. These two types of substances are considered to be the main active ingredients of honeysuckle to exert its heat-clearing, detoxifying and anti-inflammatory hurricane functions. Recognizing this, there are joint research institutes of companies that have established a functional food development research group. Finally, an okra tea with health benefits has been developed. The company has established a tea production line to ensure the supply of related health products.
There are also companies that extract okra polysaccharides, okra oligopeptides and other products from okra. Among them, the former has an inhibitory effect on the proliferation of human tumor cells and the latter has an anti-wrinkle effect. For the extraction of polysaccharides, it was previously discovered by scholars. Microwave-assisted extraction and cellulase extraction can achieve the separation of polysaccharides and okra. It was found through investigation that cellulase-extracted okra polysaccharides have advantages over microwave extraction, and that enzymatic reactions require specific temperature conditions. Needs enzymatic reaction tank as container for operation.
It can be seen that okra as an introduced vegetable has unparalleled advantages in its nutritional value. Therefore, okra considers how to bring out the nutritional value of okra products in the process of deep-processing products. Meet the needs of people today for health foods.
