胆固醇的克星，生命的钥匙，是这个天然成分
植物甾醇被科学家们誉为“生命的钥匙”，是坏胆固醇的克星，世界心脏组织、美国心脏协会、英国心脏基金会、德国营养医学和食疗学会、澳大利亚心脏学会等世界权威机构均大力推荐，全球47个国家认可并将其应用于食品领域。
Phytosterols have been hailed by scientists as the "key to life" and the nemesis of bad cholesterol. They are highly recommended by world authoritative organizations such as the World Heart Organization, American Heart Association, British Heart Foundation, German Society for Nutritional Medicine and Diet Therapy, and the Australian Heart Association. 47 countries around the world recognize and apply it in the food field.
植物甾醇是植物体内的一种天然活性物质，至今发现了100多种，常见的有β-谷甾醇、豆甾醇、菜油甾醇和菜籽甾醇四种。农业农村部批准作为饲料添加剂使用的植物甾醇，是采用大豆油/菜籽油，经物理提纯而得。
Phytosterol is a natural active substance in plants, more than 100 kinds have been found so far, the common β-sitosterol, stigmosterol, rapeseed sterol and rapeseed sterol four kinds. The phytosterol approved by the Ministry of Agriculture and Rural Affairs as a feed additive is obtained by physical purification of soybean oil/rapeseed oil.

植物甾醇的主要功效
The main effect of plant sterols
目前植物甾醇在日常生产中的很多领域都在应用，主要功效表现在以下几个方面。
At present, plant sterols are applied in many fields of daily production, and the main effects are shown in the following aspects.
1）植物甾醇具有较强的抗炎作用，具有能够抑制机体对胆固醇的吸收、促进胆固醇的降解代谢、抑制胆固醇的生化合成等作用。
1) Plant sterols have strong anti-inflammatory effects, which can inhibit the absorption of cholesterol, promote the degradation of cholesterol metabolism, and inhibit the biochemical synthesis of cholesterol.
2）用于预防治疗冠状动脉粥样硬化类的心脏病，对治疗溃疡、皮肤鳞癌、宫颈癌等有明显的疗效；可促进伤口愈合，使肌肉增生、增强毛细血管循环；还可作为胆结石形成的阻止剂。
2) It is used for the prevention and treatment of coronary atherosclerotic heart disease, and has obvious curative effect on the treatment of ulcer, skin squamous cell carcinoma, cervical cancer, etc.; It can promote wound healing, muscle proliferation and capillary circulation; It can also be used as an inhibitor of gallstone formation.
3）植物甾醇对皮肤具有很高的渗透性，可以保持皮肤表面水分，促进皮肤新陈代谢、抑制皮肤炎症，可防日晒红斑、皮肤老化，还有生发、养发之功效。可作为W/O型乳化剂，用于膏霜的生产，具有使用感觉好（辅展性好、滑爽不粘）、耐久性好、不易变质等特点。
3) Plant sterols have high permeability to the skin, can keep the skin surface moisture, promote skin metabolism, inhibit skin inflammation, can prevent sunburn erythema, skin aging, and hair growth, hair nourishing effect. It can be used as W/O emulsifier for the production of cream, and has the characteristics of good feeling (good ductility, smooth and non-stick), good durability, and not easy to deteriorate.
4）植物甾醇还是重要的甾体药物和维生素D3的生产原料。
4) Plant sterols are also important steroidal drugs and vitamin D3 production raw materials.
植物甾醇的来源
Source of phytosterols
植物甾醇广泛存在于植物的根、茎、叶、果实和种子中，是细胞膜的主要构成成分之一，是维生素Ｄ、甾体化合物及多种激素合成的前体物质，国际上商业化的植物留醇70%来源大豆油脱臭留出物（DD油）。依托酶催化技术从DD油中提取植物甾醇，具有成本低廉、工艺简便、环保等优势，生产出的植物甾醇，在纯度、品种类别等各个方面均具有较大优势。
植物甾醇在养殖业中的应用展望
Application prospect of phytosterols in aquaculture industry
植物甾醇在医药、食品、化妆品、饲料等行业中具有较为广泛应用。作为一种新型功能性饲料添加剂，植物甾醇可降低禽蛋和禽肉中胆固醇的含量, 增进动物蛋白质合成，在动物生产上，科学使用植物甾醇能促进动物生长、改善机体健康、提高畜产品质量，还可作为畜禽饲养的肝功能改善剂，对于降低养殖成本、提高经济效益具有积极作用；作为一种功能性添加剂，植物甾醇还可以在饲料工业中代替抗生素，具有广阔的应用前景。
