A study was conducted to assess the performance of evaporative coolers for the storage of fruits and vegetables. Two evaporative coolers [Aluminum-cladded burnt-clay-brick evaporative cooler (ABBEC) and non-cladded burnt-clay-brick evaporative cooler (NBBEC)] for the storage of fruits and vegetables were designed, constructed and tested. The evaporative coolers comprised of double burnt-brick walls (1.29×2.55×2.56 m) external and (1.13×1.27×2.08 m) internal, (L×W×H). The physicochemical, microbiological and sensory attributes of fresh tomatoes stored in the coolers and at ambient were evaluated. Metabolic rates of tomatoes were highest at ambient storage followed by NBBEC with the least value in ABBEC. Beta carotene, ascorbic acid and acidity decreased while total soluble solids, pH and microbial loads increased during storage of tomatoes. Fresh tomatoes stored in ABBEC exhibited lower biochemical and physiological reaction rates hence tissue breakdown, colour changes, pH and titratable acidity were lower in ABBEC than NBBEC and ambient. ABBEC storage further improved the microbial quality and shelf life of fresh tomatoes. The aluminum cladded evaporative cooler was the best storage facility for stop gap extension of shelf life of tomatoes.

Active packaging aims to extend the shelf life of fruits and vegetables using active agents such as Oxygen, Carbon-di-oxide, ethylene scavengers and moisture absorber. Intelligent packaging provides information about the fruits quality inside the package to the customer and this packaging technology detects the internal changes of fruits and vegetables using sensors and indicators. Further to improve the post-harvest storage PCM such as Rubitherm can be used depending on the package box dimension to remove the field heat from the products and maintain its temperature with low variation during transport and display. Gel packs having less weight with PET and PS can also be an alternate method in the packaging. The application of these technologies may lead to a revolution in post-harvest storage, transportation, and further retail sale. This paper reviews the theoretical principles of food packaging and recent developments in packaging technologies using PCMs. Keywords: Active packaging, Intelligent packaging, Phase change materials, Shelf life extension, Fruits

Introduction. The Russian Arctic, also called the Far North, attracts a lot of people who work on a fly-in fly-out basis. These temporary residents experience the negative impact of the harsh climate and suffer from unvaried diets and poor ration. Freeze-dried products might be the optimal solution to this problem. The research objective was to find a rationale for the use of freeze-dried long-storage products in the diets of temporary residents in regions with harsh climatic conditions. Study objects and methods. The research featured scientific publications on two topics: 1) nutrition and diet of shift workers in the Far North, 2) development of freeze-dried products for long-term storage in extreme conditions. Results and discussion. Shift workers consume a lot of fats and carbohydrates, while their diet lacks complete proteins, vitamins, minerals, dairy products, and fresh fruits and vegetables. Taking into consideration the high content of sugar and confectionery, the diet ruins the health of the temporary residents and causes alimentary chronic non-infectious diseases. A healthy diet for the Russian Arctic should correspond to the metabolic profile typical of people in chronic environment stress and be complete both quantitatively and qualitatively. Important food products are difficult to deliver to the Far North. As a result, they are microbiologically and chemically contaminated. Therefore, the region needs high-quality functional products with prolonged shelf life. Conclusion. Freeze-dried fermented milk products, fruits, and vegetables can help temporary residents of the Far North to maintain their usual food patterns. Freeze-dried foods have a long shelf life in unregulated temperature conditions, which can solve the issue of food supply even to the most remote settlements.
