The contents can include price, trademark and latest. Sales date, etc. This technology is more environmentally friendly than traditional paper label technology.
Plant extracts refers to substances extracted or processed from plants (all or part of plants) with appropriate solvents or methods. They can be used in pharmaceutical industry, food industry, daily chemical industry and other industries.

It is understood that the equipment is developed by a Spanish company, and apples, bananas, citrus and other fruits can be applied. At present, the technology has been applied in the French Lok Fu supermarket, and a melon sold for it is printed with the trademark of Carrefour. In addition, the company also hopes that the major supermarkets in the UK will be able to use this technology to label the vegetables with laser labels before the end of this year. Other foods will also use laser labels next year.
The company's CEO, Jamie Sanfiniks, said that laser tags do not require paper, ink or glue and are therefore more environmentally friendly than traditional paper labels. At the same time, the use of laser tags can help retailers better control the sale of goods. For example, retailers use lasers to date on the latest sales date to better manage the perishable food on their shelves and to quickly and easily expire. Food is evacuated from the shelves.
Laser label technology has entered Japan and other countries, and the US Sunkist Fruit Farmers Company intends to introduce the technology into the United States and name it “Natural Light Labelâ€. Adrian Barlow, CEO of the British apple and pear company, said that laser labeling technology will have great potential in the UK. But he also warned that the accuracy and legitimacy of laser tag technology and consumer awareness of the technology is very important, and consumers need to be convinced that the technology does not affect the natural state of the food. However, the laser food company said that market research shows that consumers will be more willing to choose laser label technology instead of traditional paper label technology.
There is a conceptual intersection between plant extracts and Chinese herbal extracts. The raw materials of plant extracts in China mainly come from Chinese herbal medicine. Therefore, domestic plant extracts can also be called traditional Chinese medicine extracts to some extent. They are generally included in the category of traditional Chinese medicine products in China's export trade statistics.
China's plant extracts come from the traditional Chinese medicine industry, and the overall development time is relatively late. In the 1970s, some Chinese herbal medicine factories began to use mechanical equipment to extract active ingredients, but only as part of production, plant extracts have not been produced on a large scale. Until the 1990s, the international trend of returning to nature rose, and people began to tend to use natural plant products. During this period, China's foreign trade rose, and China's Plant Extract industry was getting better and better. In the 21st century, with the application of more advanced extraction methods such as enzymatic extraction, ultrasound, supercritical extraction, membrane separation technology and microwave extraction technology, the yield of extract has been greatly improved, and China's plant extract industry has entered a golden period of development. From 2010 to 2015, the production capacity and export volume of plant extracts increased steadily and rapidly every year, and the proportion of plant extracts in the export of traditional Chinese medicine also increased a lot. Since 2016, the market situation of plant extracts has changed.
1. According to the content of active ingredients, it can be divided into three categories: effective monomer extract, standard extract and ratio extract;
2. It is divided into glycosides, acids, polyphenols, polysaccharides, terpenes, flavonoids, alkaloids, etc;
3. According to the product form, it can be divided into vegetable oil, extract, powder, lens, etc.
4. According to the purpose, plant extracts can be divided into natural pigment products, traditional Chinese medicine extract products, extract products and concentrated products.
Application
The application scope of plant extracts has been very wide nowadays. In addition to traditional Chinese medicine products, with the gradual increase of people's trust and dependence on natural products, a large part of plant extracts have been used in health products and food ingredients. In addition, plant extracts have been used in cosmetics and feed in recent years.
