油脂在长期贮藏中易受多种因素影响发生氧化酸败,不仅影响食物感官,降低营养价值,同时产生一些有毒物质导致人体衰老、癌症以及多种慢性疾病的发生。天然抗氧化剂因具有安全性高、抗氧化能力较强的特点,已被普遍运用于油脂抗氧化中。从酚类、色素类、多肽类、甾醇类物质以及多糖类物质5个方面,综述了近年来从动植物中提取的天然抗氧化物质对油脂抗氧化的作用,旨在为天然抗氧化剂的开发、应用,油脂储存、保质研究提供参考。 相似文献

天然抗氧化剂抑制油脂氧化的研究进展 总被引:5,自引:0,他引:5
油脂氧化是食品工业中经常遇到、严重影响食品品质的主要问题之一.虽然应用各类人工合成抗氧化剂在抑制食品中脂肪氧化的问题上取得了比较好的效果,但是这一类抗氧化剂会带来食品安全问题.深入研究和推广应用天然抗氧化剂是同时解决脂肪氧化和食品安全问题的重要途径. 相似文献

Antioxidant effects of natural antioxidants in 73%‐lean ground beef patties during refrigeration were studied. Samples were subject to an antioxidant treatment (pomegranate extract, grape seed extract, butylated hydroxyanisole, or no treatment) and an irradiation treatment (0 or 1.5 kGy) before being evaluated for both uncooked and cooked indicators of lipid oxidation. Chemical evaluation of antioxidant activity were determined over 9 d through measurement of thiobarbituric reactive substances values. Physical evaluation of antioxidant activity was monitored by changes in physical color and sensory odor analysis on patties before and after cooking. Butylated hydroxyanisole extended the induction period of oxidation in all unirradiated beef patties better than the natural antioxidants. Panelists were able to distinguish a difference (in terms of oxidation attributes) between patty samples of different antioxidant and irradiation treatments while samples were uncooked, but unable to distinguish a difference between patties after cooking. 相似文献

Due to the potential toxic effects of synthetic antioxidants, natural antioxidant sources especially fruits are being preferred now-a-days for use in different meat products. The majority of the antioxidant capacity of a fruit is especially because of numerous phenolic compounds. Many of the phytochemicals present in fruits may help protect cells against the oxidative damage caused by free radicals, thereby reducing the risk of degenerative diseases such as cardiovascular diseases, various types of cancers, and neurological diseases. Various parts of the fruit including their byproducts like skin and seeds have been used in meat products. Plum has been used as plum puree, prunes (dried plum), and plum extracts. Grape skin, seed, peel extracts, and grape pomace; berries as cakes and powder extracts; pomegranate rind powder and its juice; and most of the citrus fruits have proved beneficial sources of antioxidants. All these natural sources have effectively reduced the thiobarbituric acid-reactive substances (TBARS) values and free radical frequency. Thus, lipid oxidation is prevented and shelf life is greatly enhanced by incorporating various kinds of fruits and their byproducts in meat and meat products. There is a great scope for the use of fruits as natural sources of antioxidants in meat industry. The review is intended to provide an overview of the fruit-based natural antioxidants in meat and meat products. 相似文献

对菜籽油(RSO)和辛酸(CA)酶法合成结构脂质(SLs)的特性和氧化稳定性进行了研究,比较了α-生育酚(α-TOH,25~1000 mg/kg)、L-抗坏血酸棕榈酸酯(AP,25~200 mg/kg)、特丁基对苯二酚(TBHQ,25~200 mg/kg)、二叔丁基对甲酚(BHT,25~200 mg/kg)、叔丁基羟基茴香醚(BHA,25~200 mg/kg)和没食子酸丙酯(PG,25~200 mg/kg)等抗氧化剂对提高SLs氧化稳定性的效果。结果表明,RSO和SLs在110℃下诱导时间(IT)分别为7 h和6 h,添加α-TOH几乎不能提高SLs的氧化稳定性(r为0.169);而添加TBHQ、PG、BHA、BHT和AP都能显著提高SLs的氧化稳定性(r分别为0.994,0.948,0.975,0.974和0.985)。SLs和RSO在60℃下加热15 d过氧化值(PV)、共轭二烯酸值(CD)和茴香胺值(AV)显著增加,但RSO和SLs的PV、AV增加幅度没有显著差异(P0.05),而它们的CD变化幅度有显著差异(P0.05)。SLs中CA的插入,一方面增加了饱和脂肪酸,提高了氧化稳定性;另一方面稀释了原料油脂中所含的抗氧化剂浓度,降低了氧化稳定性。 相似文献

将迷迭香提取物、茶多酚、留兰香提取物、竹叶提取物及甘草提取物添加到乳化肠中,替代部分亚硝酸 钠,研究其对乳化肠色泽稳定性和抗氧化性的影响。结果表明:与空白对照组相比,天然抗氧化剂的添加促进了亚 硝酸钠的发色,延缓了乳化肠红度值(a*)的降低,降低了乳化肠的脂肪氧化程度。与0.010%的亚硝酸钠相比,竹 叶提取物的护色作用较强,且添加量为0.030%时乳化肠的a*最大;留兰香提取物与茶多酚的护色效果次之,添加量 分别为0.040%和0.024%时乳化肠的a*最大;迷迭香提取物与甘草提取物的护色效果最弱。与0.020%异抗坏血酸钠 相比,茶多酚与竹叶提取物的抗氧化活性较强,它们的添加量为0.030%时表现出较好的抗氧化活性;迷迭香提取物 与留兰香提取物的抗氧化效果次之,它们的添加量分别为0.030%和0.040%时具有较强的抗氧化活性;甘草提取物 的抗氧化活性最弱。天然抗氧化剂对乳化肠中脂肪氧化的抑制作用与其对色泽的保护作用有着良好的对应关系,整 体而言,竹叶提取物的护色及抗氧化效果最佳。 相似文献
