肉制品作为具有高生物价值的蛋白质、矿物质、维生素和过量生物活性化合物等基本营养素的来源,被人们广泛接受和喜爱。但是肉质品在不当环境下储存极易腐败变质,因此亟需寻求绿色、高效的保鲜技术。近年来,淀粉作为一种可成膜多糖被广泛用于制备生物可降解薄膜以用于食品包装,通过作为抗氧化抗菌生物活性物质载体或隔绝氧气等来维持肉制品的新鲜度,目前基于淀粉与成膜材料联合制备的复合膜已成为肉制品防腐保鲜技术的研究热点。因此,本文通过综述淀粉的基本性质、基于淀粉制备的食品复合膜的结构及特性,以及重点阐述淀粉基食品薄膜与精油、天然提取物、纳米复合材料等联用在肉制品保鲜中的研究进展,以期为淀粉基食品薄膜在肉制品保鲜中的应用提供理论参考。 相似文献

Dempster JF 《Meat science》1985,12(2):61-89
The World Health Organisation (WHO) in 1980 clarified the position regarding the medical acceptability of irradiated foods when it said‘…no health hazard results from consuming any food irradiated up to a dose of one megarad (1 Mrad)’. This resulted in renewed interest in irradiation as a cost-effective alternative to traditional preservation methods such as canning and freezing. Thus, radurisation (the application of ionising radiation at a dose level which substantially reduces the microbial population) increases the shelf life of poultry, comminuted meat and meat dishes significantly. Low dose irradiation, or radicidation, eliminates parasites such as Trichinae and cysticerci in pork and, very importantly, salmonella organisms in poultry and red meat. Therefore, irradiation has an important rôle to play in public health protection. High dose irradiation, or radappertisation (‘cold sterilisation’), uses doses in excess of 1 Mrad and is analogous to retorting as understood in the canning industry. However, it can adversely affect quality in producing ‘free radicals’ in high protein foods such as meat. To prevent this, special precautions are necessary, e.g. irradiation is conducted at very low temperatures and the product is usually vacuum packed.A further potential use of irradiation is its ability to reduce the quantity of nitrite necessary in cured meats. This may become of practical significance if legislation further reduces the amount of nitrite permitted in these products. 相似文献

熏烧烤肉制品包装方式研究进展 总被引:1,自引:0,他引:1
如何延长货架期、提高肉品质量一直是肉类企业关注的焦点,对肉品进行恰当的包装销售已是一个势在必行的发展趋势。包装具有保护食品原有品质及延长食品货架期的作用。熏烧烤肉制品是受消费者喜爱的传统肉制品,在肉制品体系中占有相当重要的地位,但在储存和销售过程中易发生腐败变质,致使其营养价值降低,适口性及外观改变,同时还可能导致有毒有害物质的产生。该文主要基于熏烧烤肉制品的特点,同时通过与生鲜肉包装方式的比较,综述了不同包装方式对熏烧烤肉制品品质的影响,重点介绍了不同包装方式在熏烧烤肉制品中应用的利弊。 相似文献

One of the main concerns regarding safety of food packaging is the possible migration of chemical substances (monomers and other starting substances, additives, residues) from food contact materials into foods. To evaluate the effect of the fat content and of the temperature of storage on the migration from plastics packaging films into meat products as an important class of foodstuffs, the kinetic mass transport of a model migrant (diphenylbutadiene) from low density polyethylene (LDPE) film in contact with different meat products was investigated. From the data, the diffusion coefficients were calculated for the applied test conditions, by use of a mathematical model. The results showed that migration increased with fat content and storage temperature. Analysis of migration data corresponding to minced pork meat containing different amounts of fat, stored for 10 days at 25°C, revealed an excellent relationship between migration level and fat content. This behaviour was also found for other types of meat products (chicken and pork neck). A simplifying mathematical model was applied to derive effective diffusion coefficients in the polymer which, however, do take kinetic effects in the meat also into account. In the case of pork meat contact, the effective diffusion coefficients derived from mathematical modelling were ten times higher for storage at 25°C (1.88×10(-9)cm(2)s(-1)) than for storage at 5°C (1.2×10(-10)cm(2)s(-1)). 相似文献
