| Lipid oxidation is one of the most important problems that decrease the shelf life of meat and meat products. Antioxidants are used to reinstate free radicals thereby retarding lipid oxidation, delay development of unpleasant-flavors, and improve color stability.Application of synthetic antioxidants to mitigate oxidative damage may consider unsafe for consumers. Furthermore, the recent growing in the understanding of the consumers about these hazards resulted in the replacement ofsynthetic antioxidants with natural bioactive compounds. Plant materials are rich sources of bioactive phenolic compounds; hence they can be an effective alternative to synthetic antioxidants. This review presents an overview regarding the new advances in the application of natural antioxidant compounds such as herbs, spices, fruits, plant essential oils and extracts in meat and meat products to improvetheir quality and shelf-life.

X-ray is a non-thermal technology that has shown good efficacy in reducing pathogenic and spoilage bacteria, viruses and parasites. X-ray hygiene technology resulted in a high microbial loss in numerous food products, such as dairy products, ready-to-eat shrimp, oysters, fresh products, strawberries, shredded iceberg lettuce, and spinach leaves. Some X-ray studies on food safety have shown that X-ray is an effective technology and is also an appropriate alternative to the electron beam and gamma rays, and can be used in the food industry without side effects on human health. Besides, we reviewed the X-ray effect on the nutritional value of food. Therefore in this study, we aimed to review the available pros and cons of current studies regarding X-rays’ effects on the food industry.
