Food spoilage is common in life, and it also brings us a lot of troubles, but scientific research and practice have proved that certain foods will not degenerate under the correct storage conditions.
1, white wine
Liquor with more than 10% alcohol content has its own disinfection. Under sealed conditions, microorganisms are not easily invaded and difficult to reproduce, so they are never degenerate. However, this does not mean that the longer the wine is kept, the better. After 5 years of ordinary flavor liquor, the taste will be lighter and the aroma will be weakened; the Maotai-style wine is a good wine, but whether the aroma stored for many years is good Wine is currently inconclusive.
2, honey
Fresh and mature honey is a transparent or translucent jelly-like viscous liquid. Sugar accounts for more than 3/4 of the total amount of honey and has a low moisture content. Bacteria and yeast cannot survive in honey. In addition, honey also contains 0-1% to 0.4% of bacteriocin. Therefore mature honey is not easy to degenerate for a long time. However, if it is not mature honey or a poor quality product that has been mixed with water, it will ferment and bubbling, sour, and inedible for a while.
3, vinegar
Vinegar has antibacterial and bactericidal effects and can be used for preservation and preservation of food, such as sour stains. The vinegar has a relatively long shelf life, but it is also affected by the process and raw materials. Better brewing vinegar, sealed with jars and placed underground, the longer the vintage, the more mellow the taste.
4, solid sugar
Solid sugars include commonly used white sugar, white sugar, rock sugar, and single crystal rock sugar. Solid sugars, due to their low internal water content and strong osmotic pressure, are not conducive to the growth of microorganisms and are difficult to be contaminated. Sugar is also commonly used to preserve foods such as candied fruit and preserved fruit. However, sugar tends to absorb moisture. If it is improperly placed and its nature changes, it will be contaminated by microorganisms.
5, salt
Salt is the main component of sodium chloride, chemical properties are very stable. Like sugar, table salt is often used to preserve food and is a natural preservative. The iodized salt that we often eat, if it is not protected from light and high temperature, the iodine content will be reduced for too long, but the quality of salt will not change.
Plant extracts refer to a class of substances derived from plants that have one or more biological functions. Can be separated by physical and chemical extraction of one or more effective components formed by natural products.
There are many kinds of plant extracts. At present, natural plant extracts mainly include essential oils, saponins, alkaloids, polysaccharides, polyphenols, flavonoids and so on. According to the biological activity, it can be divided into antioxidants: grape seed extract, green tea extract, pine bark extract, etc. Immune modulators: ginseng extract, gynostemma pentaphyllum extract, Ganoderma lucidum extract, etc. Improve cardiovascular function: ginkgo biloba extract, lotus seed heart extract, rhodiola extract, etc. Sedative: valerian extract, hop extract and so on.
According to their own characteristics in the market application of plant extracts can be roughly divided into six categories: coloring, seasoning, medicinal, health, dietary supplements and feed additives. Natural plant pigments refer to pigment components in roots, stems, leaves, flowers, fruits and bark of plants, such as turmeric, sappanwood, indigo, safflower, black bean and green walnut peel. Natural plant pigments are widely used in food, textiles, cosmetics, medicine, leather industry, printing and dyeing and other industries.
Plant extracts are rich in ingredients that can effectively stimulate the senses, such as sweeteners and volatile substances. Natural sweeteners, such as stevia glycoside and grosvenin, are popular new sweeteners. They are not only sweet, but also ideal substitutes for sucrose. Essential oils are concentrated volatile substances that are commonly used in the preparation of fragrances and are widely recognized in plant extracts.
Contained in the plant extracts of saponins, alkaloids, polyphenols, flavonoids and other ingredients are widely study has many biological activities, such as antioxidant, antibacterial, anti-inflammatory, improve animal production performance, antivirus, enhance immunity, etc., for human and animal health has the effect of nots allow to ignore, and the development of its pharmacology and health care function has become the main trend of plant extracts.In addition, as a dietary supplement, it is one of the main applications of various plant extracts. Such as oligosaccharides (oligosaccharides, oligosaccharides, oligosaccharides, galactose, etc.) dietary fiber, soybean protein, dietary fiber, wheat albumin, L-arabinose, sugar alcohol (xylitol, malt heavy sugar alcohol, sorbitol, etc.) and other natural plant food additives have been widely used in the food health care market. Many plant functional ingredients with anti-inflammatory, antioxidant and bacteriostatic properties are also commonly used as substitute anti-bacterial products. The application of green feed additives in livestock and poultry production has been vigorously developed, such as green tea polyphenols extract, pine bark procyanidins extract and polyanthocyanidins extract.
Due to the changes in lifestyle, working mode and consumption mode, more consumers are pursuing the life concept of "big health". The so-called "big health" refers to a concept of whole-process, comprehensive and total factor care for people's life around the basic necessities of life, life, old age, illness and death. It not only pursues individual physical and physical health, but also pursues mental, spiritual, social, environmental and family health. In the era of "great health", natural plant-based health products are the core and the key material basis.
With increasing attention to the food and drug safety, from natural plant in the development and utilization of the active ingredient is becoming more and more attention, a large number of food safety, have certain curative effect function of plant extracts have been used as raw materials in a variety of ways into functional food nutrition and health food has entered people's lives, and will play a more and more important role.
And more and more new research new discovery, predicts that the plant extract industry chain will have more members to join, there will be more business opportunities. The future domestic plant extract market will stride forward gradually to mature period!
