background: environmental problems of the plastic materials used in food packaging and the demand for food quality improvements lead to the development of packaging in natural materials. edible films such as calcium alginate extend the shelf life by acting as a selective barrier against moisture and oxygen. the main objective of this study was to explore a calcium alginate based edible film to ...

in spite of the technologies developed during the last decade, the level of food loss is still high and is reported in many countries. according to the united nations, more than 30 per cent of the mortality rate world-wide is caused by alimentary diseases. the desire of most countries to make food safer for consumption requires better food preservation and production techniques. in this regard,...

background & aim: the major aim of this study was to determine the antibacterial activity of the essential oils from five medicinal plants. experimental: the hydro-distillation essential oils from five plant species, including satureja bachtiarica, zataria multiflora, thymus daenensis, thymus carmanicus, and ziziphora tenuior (lamiaceae) which are endemic in iran. in-vitro antibacterial tes...

background: antioxidant activities of plant extracts are being studied to increase the shelf life of fish products. some plants such as urtica dioica l. (nettle) can be a good source of antioxidants. the objective of this study was to evaluate the effects of hydroalcoholic and water extracts of nettle leaf on the chemical properties of superchilled minced meat of the common kilka fish (clupeone...

Natural food preservation method refers to application of naturally produced antimicrobial compounds that are obtained from plants, animals and microbes to prevent food spoilages microorganism, proliferation and growth of food borne pathogens in food and foods products. Now it is the time of growing interest of many researchers with the application of these natural antimicrobial compounds as sa...

background: due to high content of unsaturated fatty acids, trout is susceptible to oxidative spoilage. in this study, the effects of thymus vulgaris essential oil (eo) and extract on oxidative stability of cooked rainbow trout fillet during four months frozen storage period were investigated. methods: three groups of fish fillets were treated with thyme eo and three other groups were treated w...

many food products are perishable by nature and require protection from spoilage during their preparation, storage and distribution to give them desired shelf-life. because food products are now often sold in areas of the world far distant from their production sites, the need for extended safe shelf-life for these products has also expanded. currently, there is a strong debate about the safety...

The term food preservation refers to any one of a number of techniques used to prevent food from spoiling. The following are the general methods of food preservation:  application of heat, such as canning and preserving, pasteurization, evaporation, sun-drying, dehydration and smoking,  application of cold, as ill cold storage, refrigeration and freezing,  the use of chemical substances such...

atmospheric pressure plasma (app) is an emerging non thermal technology for the improvement of food  safety. non-thermal plasma (ntp) is a neutral ionized gas that comprises highly reactive spices including, positive ions, negative ions, free radicals, electrons, excited or non excited molecules and photons at or near room temperature. ntp can be generated at atmospheric pressure that makes it ...
