So, All of authors and contributors must check their papers before submission to making assurance of following our anti-plagiarism policies. In the past few years there has been a major shift in the driving force for development of new packaging technology. Changing consumer demands for food products that are minimally processed and can prolong for longer time with minimal loss in quality, new regulations for consumer health and safety, need for packages that prevent microbial contamination, rancidity and production of off-odours, gases, off-flavours etc. Moreover, there have been changes in retail, distribution and purchasing of food products such as internet shopping. Henceforth, technologies like active packaging, interactive packaging, smart packaging, intelligent packaging, and modified atmosphere packaging are need of the hour.

Once production of your article has started, you can track the status of your article via Track Your Accepted Article. Help expand a public dataset of research that support the SDGs. Food packaging plays a vital role in preserving food throughout the distribution chain. Without packaging, the processing of food can become compromised as it is contaminated by direct contact with physical, chemical, and biological contaminants. In recent years, the development of novel food packaging Directly related, and interlinked, with food packaging is the concept of shelf life - the length of time that foods, beverages, pharmaceutical drugs, chemicals, and many other perishable items are given before they are considered unsuitable for sale, use, or consumption. Food Packaging and Shelf Life caters to the needs of scientists, material scientists, food chemists and microbiologists in the area of food packaging and shelf life.

Modified atmosphere is the practice of modifying the composition of the internal atmosphere of a package commonly food packages, drugs, etc. In food, oxygen is readily available for lipid oxidation reactions. Oxygen also helps maintain high respiration rates of fresh produce, which contribute to shortened shelf life. Oxygen scavengers may also be used to reduce browning due to lipid oxidation by halting the auto-oxidative chemical process. The modification process generally lowers the amount of oxygen O 2 in the headspace of the package.

Call Now - By: Nathan Dube on May 23rd, The goal of the process being to increase the shelf life of the product contained within. MAP improves the shelf life and freshness of many foods. These include cheese, meats, fish and other perishable food items.

This review paper discusses active, intelligent and modified atmosphere packaging as a model technology for the food industry and further reviewing the current.

Modified atmosphere packaging (MAP)

This paper reviews the current advances in modified atmosphere packaging MAP of red meat and poultry products. This type of packaging results in shelf-life prolongation by inhibiting microbial growth and promoting oxidative stability, compared to those packaged aerobically. High O 2 modified atmosphere packaging results in the desirable red colour, but it also enhances both lipid and pigment oxidation and promotes the growth of aerobic spoilage microorganisms. The presence of high levels of CO 2 in modified atmosphere packages inhibits microbial growth but can also cause meat discoloration through oxidation.

Active packaging – an overview

The biggest problem faced by the food industry in South Africa is the maintenance of quality of fresh produce during postharvest storage Munhuweyi et al. Attempts to reduce losses and maintain quality of fresh food, primarily fruits and vegetables, during postharvest storage has been a challenge and priority for the food industry Velickova et al. Strategies to prolong the shelf life of fresh-cut vegetables during storage are necessary to preserve their nutritional value and to assure food safety Conte et al. Modified atmosphere packaging MAP is the technique of sealing actively respiring produce, fresh fruit and vegetables, in polymeric film packages to achieve the modification of the O 2 and CO 2 levels within the package atmosphere Mir and Beaudry, The MA packaging technology is said to be efficient in maintaining shelf life of fresh produce during storage Sandhya, Church and Parsons reported that the combination of oxygen O 2 , nitrogen N 2 , and carbon dioxide CO 2 is frequently used when operating the MAP during storage, based on its efficiency and specific effect it has in slowing down the metabolism process of the produce.

 - У Танкадо сказано: главная разница между элементами. - Господи Иисусе! - вскричал Джабба.  - Откуда нам знать, что для Танкадо было главной разницей. - На самом деле, - прервал его Дэвид, - Танкадо имел в виду первичную, а не главную разницу. Его слова буквально обожгли Сьюзан.

Велел ему сегодня не приходить. Он ничего не сказал о том, что поменялся с тобой дежурством. У Чатрукьяна ком застрял в горле. Он молчал.

Ничего. Вроде бы на нижней ступеньке никого. Может, ему просто показалось. Какая разница, Стратмор никогда не решится выстрелить, пока он прикрыт Сьюзан. Но когда он начал подниматься на следующую ступеньку, не выпуская Сьюзан из рук, произошло нечто неожиданное.

Светлые волосы тщательно уложены. - Прошу меня извинить, - пробормотал Беккер, застегивая пряжку на ремне.  - Мужская комната оказалась закрыта… но я уже ухожу. - Ну и проваливай, пидор.

Беккер был потрясен. - А как насчет вскрытия шифров. Какова твоя роль во всем .

Но все доказательства к этому моменту будут уничтожены, и Стратмор сможет сказать, что не знает, о чем речь. Бесконечная работа компьютера. Невзламываемый шифр. Но это полный абсурд.

Сьюзан была убеждена, что это невозможно. Угрожающий потенциал всей этой ситуации подавил. Какие вообще у них есть доказательства, что Танкадо действительно создал Цифровую крепость.
