Omega-3 fatty acid is a long-chain, polyunsaturated fatty acid found in plants and marine organisms. Studies have shown that saturated fatty acids have adverse effects on health, while omega-3 fatty acids, as polyunsaturated fatty acids, have many health benefits. Different types of evidence suggest that the decrease of omega-3 fatty acid concentration can cause mood disorders. Some preliminary research results suggest that it can effectively treat a variety of mental disorders, such as bipolar disorder, schizophrenia and dementia. For pregnant and lactating women, it is a safe and effective treatment.
There are eight sources of omega-3: Antarctic krill, seals (seals), deep-sea fish, purple perilla seed, flaxseed, qiyazi (qiyazi), seaweed, South American oil vine and yak.
Fish / fish oil: it should be noted that only deep-sea fish are rich in omega-3. Unlike other three plant products, fish contain cholesterol. People with diabetes, hypertension and other diseases should consult a doctor before consuming fish oil to supplement omega3. In addition, fish is a common allergen, which will cause allergic reactions in many people, including children. If you are prone to allergic constitution before eating, please consult your doctor. Deep sea fish oil is rich in unsaturated fatty acids such as EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), which can significantly reduce cholesterol and soften blood vessels. Ruan Guangfeng, an expert of China food and nutrition information exchange center, said that EPA and DHA are the main components of fish oil that play a role in health care for the human body. They come from fish fat. The quality of fish oil is marked by the content of EPA and DHA.

Seaweed: the deep-sea rhynchophyta contains Omega-3. Some deep-sea fish ingest omega-3 because they prey on these algae. Because the existing methods of cultivating and extracting seaweed oil do great harm to the environment, it still needs some time to improve and improve in order to realize commercial production.
Longjing tea processing
Longjing tea is a tea unique to Zhejiang. In addition to West Lake Longjing tea area, Chunan, Linan also has a small amount of production. In 1960, some high-end Longjing teas were expanded in Fuyang, Xiaoshan, and Yuhang. The annual output was 250 tons. In 1965, in order to maintain the reputation of Longjing Tea, it was only produced in the West Lake Longjing Tea Region in Hangzhou. The production of the “Xianghu Banner Gun†was produced in Xiaoshan Wenjiabang and Changhe, and no Longjing Tea was produced in other areas. Also reduced accordingly. In 1981, to meet the market demand for Longjing tea, the "Xiang Lake Flag Gun" was renamed as "Zhejiang Longjing" tea. Since 1985, all the tea regions in the province have developed Longjing tea production, both of which are called "Zhejiang Longjing Tea". The amount is about 5,000 tons. Longjing tea has a unique processing technology. The initial processing of high-grade Longjing tea still uses the traditional hand-frying method. It divides the two processes of the pot and pot to bring, shake, and ride (top), smashing, dumping, smashing, and straightening. Ten different techniques such as grasping, deduction, and grinding are used to fry in a wok. In the 80s, a special electro-frying pan for the initial production of Longjing Tea was developed. The temperature is easy to control and it is very beneficial to improve the quality of Longjing Tea. It has been widely used. Low-end Longjing tea processing points to kill green, rub, two green and the pot 4 procedures. In the 1990s, flat tea frying machines have been developed to mechanize and fry flat tea. The implementation of mechanization and frying will help reduce labor intensity and improve ergonomics. However, the technology is still unsatisfactory. The fryed Longjing tea has a rough appearance and can only be used as medium and low-grade Longjing tea or flag gun tea.
