Abstract: Open sun drying of food product is the traditional method since ancient days. The recent technologies like vacuum drying, steam drying, spray drying, microwave drying etc. are used for drying food materials, need fuel or electricity making the procedure of drying costlier. The alternative to these is the solar dryer. Cabinet Solar Dryer is one of the dryers developed. It is cheaper, easy to handle and effective means for drying because using it solar energy can be utilized meaningfully. Solar energy being the renewable source of energy is abundant, available at free of cost, clean, pollution free and lasting for millions of years in future. In solar dryer safe and appropriate drying of food product from nutrition point of view can be done. Also the product is free from contamination. These are the advantages over open sun drying. In the present study, sensory parameters as colour, flavour, taste & texture, macronutrients like energy value, protein, carbohydrate, fat and dietary fibre as well as micronutrients (minerals and vitamins) like potassium, phosphorous, magnesium, calcium, iron and vitamin C were estimated in the sample of cabbage in both the methods, solar dryer as well as open sun drying. The results are noticeable.
