肉制品无论是中式制品或西式制品,在一定的保存期内,都会发生氧化现象,其最主要的感观特征表现为食品退色或褐变,肉制品的氧化一直是困扰企业生产发展和消费者食用安全的难题,因此在肉制品中合理添加抗氧化剂是非常必要和有效的,所谓抗氧化剂是阻止或延缓食品氧化,提高食品的稳定性,延长食品贮存期的添加物质,作为食品抗氧化剂应具备几个条件:(1)可食用,无毒、无害。(2)与食品可以共存,(3)微量添加即有效,(4)对食品本身的感官性质没有影响。 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

Antioxidants are added to fresh and processed meat and meat products to prevent lipid oxidation, retard development of off‐flavors, and improve color stability. In the food industry, they can be divided into natural and synthetic antioxidants. Synthetic antioxidants have been confirmed for their toxicological and carcinogenic effects. Thus, the food industry now chooses natural products over synthetic ones. This review provides an overview of the current trends in the use of antioxidants from natural sources, for potential applications in meat and meat products. These natural antioxidants contain some active compounds, which exert antioxidative potential in meat and meat products by different mechanisms of action. The efficient extraction of these antioxidants from their natural sources, along with establishing their in vitro and in producto antioxidant activity, has been a great challenge for researchers engaged in this field. Therefore, this review is focused on all these aspects, along with current studies related to this area, to provide in‐depth information to readers. 相似文献

天然抗氧化剂对动物肉品的作用 总被引:3,自引:1,他引:3
肉品中含有丰富的脂肪和蛋白质,在生产、加工及运输过程中极易被氧化,极易发生氧化酸败,使肌肉中的肌红蛋白突发褐变,失去原有的食用价值和商业价值。为了减少肉品的氧化,提高产品品质,添加抗氧化剂己经成为必然选择。天然抗氧化剂具有较高的安全性、抗氧化能力、无副作用和防腐保鲜等优点。本文对天然抗氧化剂在肉品中的应用进行主要的综述。 相似文献

肉品的过度氧化严重影响产品质量,给肉品企业造成巨大的经济损失。单宁作为天然抗氧化剂具有资源丰富、可再生、价格低廉、食用安全等优势,且抗氧化效果与合成抗氧化剂相当。单宁在生物体内对机体具有抗氧化作用,其调控机制是一个多途径、多靶点的复杂过程。在肉品加工贮藏过程中,单宁也可通过清除自由基、螯合金属离子等机制发挥抗氧化作用。因此单宁不仅可添加到动物日粮中减缓屠宰后肉的氧化,而且可通过直接添加到肉或肉品包装材料中等方式发挥作用。本文综述单宁在动物体内及肉品加工贮藏过程中的抗氧化调控机制和氧化评价方法,并分析单宁的抗氧化作用在肉品中的应用现状,以期为单宁作为抗氧化剂的广泛应用提供理论参考。 相似文献

ABSTRACT: This study was carried out to determine the effect of processing and cooking on n-3 polyunsaturated fatty acid (PUFA) stability and to determine the efficacy of antioxidants (ANTI) to minimize lipid oxidation in cooked n-3 PUFA-fortified meat products. An emulsion of n-3 PUFAs (25% algal oil) was incorporated into ground turkey, pork sausages, or restructured hams (500 mg n-3 PUFA/110 g meat) with or without an "antioxidant cocktail" containing citrate (0.5% w/w), erythorbate (1 g/kg product), and rosemary (0.2% w/w). Ground turkey and pork sausages were frozen 2 d, then cooked to 71°C, and stored at 4°C for 2 d. Cooked, restructured hams were sliced, vacuum packaged, and stored at 4°C, or frozen and thawed with subsequent storage at 4°C. Treatments were CON (control), n-3 (n-3 PUFAs), CON + ANTI and n-3 + ANTI. Products were analyzed for color, lipid oxidation (TBARS and peroxide values), and n-3 PUFA profile. TBARS of n-3 PUFA-fortified treatments in ground turkey and pork sausages increased with storage ( P < 0.05); there were no changes in TBARS for CON + ANTI and n-3 + ANTI groups ( P > 0.05). For restructured hams nitrite curing appeared to delay lipid oxidation such that antioxidant treatment effects were unobservable ( P > 0.05). Overall recovery of n-3 PUFAs after heat processing was 69% to 85%, and there was no effect of storage on n-3 PUFA concentration in raw or cooked products ( P > 0.05). Sensory scores for n-3 treated restructured hams were lower than controls ( P < 0.05). Results suggested that cooking resulted in some losses of n-3 PUFAs in fortified meat products and that an "antioxidant cocktail" protected against lipid oxidation during subsequent storage in non-cured meat products. 相似文献
