SETi to enter the Chinese market UV LED to keep fruits and vegetables longer

The United States South Carolina in 230-355nm wavelength DUV (deep UV) LED element and the sensor module manufacturers Electronic Technology Co Ltd (SETi) the sale of deep ultraviolet (DUV LEDs) China lamp to the market, to allow customers to extend shelf life of fresh products successfully.

SETi company's marketing director David Xu said; "previously, storage and preservation method of China huge domestic market and international market Vegetable & Fruit can withstand low efficiency, while the SETi saw this piece of business, providing services to customers to fight for China. "

"Most of the fruits and vegetables in China are currently using chemical or pesticides. In fact, the use of deep ultraviolet (DUV) LED technology will be more secure for consumers. The current consumed by the LED lamp is about 2 watts to 3 watts, and is harmless to the human body or the product. We found considerable potential in the Chinese market, decided to fight for such an opportunity. "

At present, SETi continues to supply sensor chips to the Chinese market, while providing standard and customized products.

SETi in November 2015 in China to sell the product, and is still in the initial stage of development, is expected to be 6 months of research and development, but the Chinese market is optimistic about the market outlook.

In November 2015, after the release of iFresh in Shanghai, SETi news, has poured into more than 100 companies asked, expressed interest in the product. In addition, China's largest media CCTV (CCTV) also produced a documentary, is expected to broadcast in 2017.

According to the company released a white paper, the United States Department of agriculture (USDA) completed the study demonstrated that the UV LED light wavelength ranged from 285nm to 305nm, or UVC in the spectral range of the light can improve the fresh Vegetable & Fruit in the refrigerator shelf life.

Data on lettuce and strawberry, as well as data from all relevant studies have shown that polyphenols (polyphenol compounds) in fruits and vegetables can be maintained for a long time under the UV LED mask.

The white paper also mentioned in the USDA study, some fruits and vegetables shelf life in UV LED light to enhance two times. Especially in the strawberry UV LED irradiation, compared to other fruits and vegetables, a substantial extension of shelf life.
