The human tongue has a range of specific taste sensation neural receptors called taste receptors which are organized mainly as papillae on the tongue. When stimulated by chemicals, natural or synthetic, organic or inorganic, cations or anions, the receptors send signals to the brain which interprets the stimulations as sweet, bitter, sour, salty, and savory (unami, meaty taste). For examples, cations such as Na+ present in the table salt evoke the salty taste, and H+ presents in acids evokes a sour taste. Organic compounds such as sugars, dextrins and glycerol result in sweet taste, glutamate results in savory taste, while many toxic compounds such as nicotine, morphine, caffeine, quinine, etc. result in bitter taste. The sensation of tastes is an evolution trait for defense against poisons (normally evoke bitter taste), and for allowance of nutrients intake (normally evoke sweet or savory taste).
Sugar is a natural sweetener as well as a nutrient consumed in vast quantity around the world. It is one of the major calorie intakes by humans. Over consumption of sugar often leads to obesity and other related medical conditions. High blood sugar level (hyperglycemia) is a manifestation of the disease diabetic mellitus; if not managed properly, it could lead to a range of medical complications. To combat these medical conditions, high potency Sweeteners with no calorie or low calorie intake are often being used to substitute sugar. Proper control of calorie intake, coupled with the use of these sugar substitutes has been very effective in managing the medical conditions.
Besides the medical indications, using sugar substitutes brings the economic benefit of lowering the cost of many foods and consumer products, from soft drinks to cakes, pasties, and even toothpastes.
A variety of chemical compounds, natural or synthetic, can evoke sweet taste, but not all of them are safe (for example lead acetate has a sweet taste but it is extremely toxic), nor are sweet taste specific (for examples, many of synthetic sweeteners can also evoke other senses of taste such as bitterness or metallic sensation). Therefore, selection of the right sweetener for a specific use depends not only on the cost, but also more importantly on the health and safety, the sweetening potency, the effectiveness under various physical conditions such as cooking temperature (heat stability) and pH, as well as other unwanted tense of tastes of the sweetener.

China's pig-raising industry has shifted from the traditional sideline to the production of profitable and specialized lean meat products. The pig's normal-temperature liquid preservation semen technology has been widely promoted and applied to pig production practices. With the deepening of the joint breeding of national and regional breeding pigs, the study of pig frozen semen technology becomes more and more urgent. In 2010, Chengdu Taifeng Animal Husbandry New Technology Co., Ltd. introduced the world-leading GVP frozen semen technology from abroad after extensive contact, careful inspection and scientific demonstration. GVP frozen semen technology successfully solved the impact of freezing, thawing and other processes on sperm quality, thereby ensuring the sow fertility rate and litter size, and avoiding the problems such as the lower transfer rate of bovine frozen semen technology. The cryopreservation of semen by GVP cryogenic semen technology is a major change in artificial insemination. It not only solves the problem of long-term preservation of semen, but also is conducive to the protection of local pig breeding resources. It also prevents semen from being restricted by time and area and is convenient for interprovincial, Collaboration between the international community to improve the utilization rate of excellent breeding pigs; and greatly prolongs the life span of genetic material of breeding pigs, enables the determination of descendants of elite pigs in the short term, preserves and restores semen supply, pedigree renewal, introduction, and reduction of production costs. All have important significance. GVP frozen semen technology is conducive to the perfection of artificial insemination system. Boar frozen semen can be supplied in large quantities after descendant determination or disease detection, providing additional guarantees for stable genetic progress and strict biological safety. From a health point of view, freeze-thawing provided sufficient time for disease detection. Semenein also provided stable semen supply for large-scale outbreaks of artificial insemination stations.
