随着社会生产力的提高,人们对包装的要求不再局限于其保护功能,也追求美观和价值。受此理念的影响,过度包装广泛存在于包装领域。过度包装不仅浪费资源,还影响食品安全,并对环境造成负担。对于直接接触食物的包装,若使用可食性原料替代一般包装材料,不仅安全还对环境友好。因此,本文探讨了可食性包装材料的类型、加工及其应用。 相似文献

包装是食品生产中的最后环节,包装的主要作用是将食品与外界环境隔离,以此防止食品污染。但是由于包装直接与食品接触,包装材料与食品安全之间存在必然联系,一旦包装出现质量问题,便会对包装内食品的质量造成影响。近些年食品安全问题屡见不鲜,这不仅会对社会正常秩序造成影响,而且还会危害消费者的身体健康。在这种情况下,我国开始加大对食品安全的监管力度,同时制定严格的食品安全检测标准。在食品生产中,大部分制造商会通过包装满足食品保存、运输的需求。为防止包装材料对食品造成污染,有必要做好食品包装材料安全性的检测工作,并在相关技术的支持下确保包装材料品质,以此构建食品安全保障屏障。 相似文献

我国粮食包装存在的问题1.包装材料的环保问题目前,我国粮食包装主要是编织袋、复合塑料袋,而这些包装袋在运输、装卸、零售等环境存在诸多问题需要解决。塑料编织袋是用塑料薄膜(聚乙烯、聚丙烯、尼龙等薄膜)制成一定宽度的窄带,或用热拉伸法得到强度高,延伸率小的塑料扁带编织而成。塑料编织袋比塑料薄膜强度高得多,且不易变形,耐冲击性也好,同时由于编织袋表面有编织纹,提高了防滑性,便于储存时的堆码,但存在防虫、防湿性差,污染环境等缺点。复合塑料袋是高阻隔性包装材料EVOH、PVDC、PET、PA及PE、PP等多层材料复合,基本上解决了… 相似文献

Over the past two decades, world olive oil consumption registered an impressive growth. Although olive oil consumption remains concentrated in the main producer countries surrounding the Mediterranean Sea (“traditional” markets), it is also growing rapidly in many other countries all over the world, where olive oil is still largely perceived as a novelty food (“nontraditional” markets). This study focuses on the Brazilian market of olive oil, which is one of the most important nontraditional markets in terms of both its dimension and growth rates. A hedonic price model has been used to evaluate whether, and to what extent, extrinsic cues impact on the retail price of olive oil. Data were collected via direct observation of several e-shops where Brazilian consumers could purchase olive oil. Results show that the retail price of olive oil is highly influenced by extrinsic cues such as branding, labeling, and packaging. 相似文献

Japan is the highest per capita consumer of packaging materials in the world. The Japanese packaging materials industry has an annual value of US$50 billion. There is a close relationship between the food and packaging industries in Japan. There is a tendency toward ingenuity in packaging designs in Japan, and Japanese food manufacturers use high-tech packaging techniques. At the same time, there is still widespread usage of traditional packaging materials (i.e., wood, earthenware, ceramics, and bamboo). Available space, energy, and a severe lack of natural resources directly affect the food packaging industry in Japan. 相似文献

This article is, to the best of our knowledge, the first investigation of Tunisian olive oil consumer behavior by the use of the conjoint analysis technique. The conjoint experiment was based on carefully selected olive oil attributes: type, taste, color, packaging, region of origin, and price. The results have important implications to improve the marketing of olive oil in the local market by focusing on key preferred attributes. Consumers were found to prefer more extra-virgin, followed by virgin olive oil, to pomace oil. They also showed higher preference for green colored olive oil with strong flavored taste. Contrary to a common belief in Tunisia, the region of origin attribute did not show significant effect on consumers’ purchasing decisions. The results show also that Tunisian olive oil consumers are price sensitive and therefore any price strategy to introduce bottled products should take into account consumers’ preferences for bulk purchase. 相似文献
