Indigenous fruits and vegetables storage using continuous adsorption refrigeration: A system modelling

The nutritional value of indigenous fruits and vegetables in Sarawak.

The proximate composition including mineral and vitamin contents of 16 fruits and 46 vegetables (leaves, fruits, palm hearts and shoots) of indigenous origin in Sarawak are provided. Fruits like dabai (Canarium odontophyllum), kembayau (Dacryodes rostrata f. cuspidata), durian nyekak (Durio kutejensis) and durian kuning (Durio graveolens) are very nutritious with high values for energy, protein...

Modelling Modified Atmosphere Packaging for Fruits and Vegetables using Membrane Systems

As living materials, post-harvested fruits and vegetables continue their metabolic activity, exhibiting progressive biochemical changes. Optimisation of environmental conditions during storage of these fresh commodities is required in order to increase their shelf life. In this work we use P systems to abstract molecular interactions that occur between plant organ, film and surrounding atmosphe...

Simulation Study of Continuous Solar Adsorption Refrigeration System Driven by Compound Parabolic Concentrator

Solar adsorption refrigeration is promising technology especially in the developing countries and remote areas because the system can be driven by solar energy without involving electricity. Therefore, it is technologically possible and socially feasible in the areas where electricity is not enough but solar energy is rather easy to obtain. The conventional system works intermittently and produ...

Vitamin retention in eight fruits and vegetables: a comparison of refrigerated and frozen storage.

Four vitamins were analyzed in several fruit and vegetable commodities to evaluate the differences between fresh and frozen produce. Ascorbic acid, riboflavin, α-tocopherol, and β-carotene were evaluated in corn, carrots, broccoli, spinach, peas, green beans, strawberries, and blueberries. Samples of each commodity were harvested, processed, and analyzed for nutrient content at three storage ti...
