Antioxidants are important for plant and animal's life or health. These are the substances that protect them from the damage produced by unstable molecules called as free radicals. There are various types of antioxidants to be reported both natural as well as synthetic such as melatonin, Vitamin C, glutathione, tocopherols and tocotrienols, BHA and BHT, etc. A new antioxidant 5-O-[6˝-(3- hydroxy-3methyl glutarate) β-D-glucodise was found while studying bioactive antioxidants from plant foods for nutraceutical product development. Antioxidants have been used for increasing shelf life of various food products including extruded product. Antioxidants, their beneficial advantages and the effect of extrusion on antioxidants were reviewed and found to be effective in increasing the shelf life. This review article discusses recent patents, presents importance of antioxidant, phytochemicals and effect of process of extrusion on antioxidants.
抗氧化剂对植物和动物的生命或健康至关重要。这些物质能保护它们免受被称为自由基的不稳定分子所产生的损害。已报道的抗氧化剂有多种类型，包括天然的和合成的，如褪黑素、维生素C、谷胱甘肽、生育酚和生育三烯酚、丁基羟基茴香醚和二丁基羟基甲苯等。在为营养保健品开发研究植物性食品中的生物活性抗氧化剂时，发现了一种新的抗氧化剂5-O-[6˝-(3-羟基-3-甲基戊二酸)β-D-葡萄糖苷。抗氧化剂已被用于延长包括挤压产品在内的各种食品的保质期。对抗氧化剂、它们的有益优势以及挤压对抗氧化剂的影响进行了综述，发现其在延长保质期方面是有效的。这篇综述文章讨论了近期的专利，介绍了抗氧化剂、植物化学物质的重要性以及挤压过程对抗氧化剂的影响。
