Studies on various concentrations of antioxidants with alkaline emulsion of ethyl oleate as pre-treatment on rate of drying, yield and colour of raisins prepared from seedless grape (Vitis vinifera L.)

The investigation was planned and executed to study the influence of various concentrations of antioxidants (Ascorbic acid, AA 500, 750 and 1000 ppm and Benzyl adenine, BA 50, 100 and 150 ppm) with alkaline emulsion of ethyl oleate (AEEO, 2.4% K2CO3 + 1.5% ethyl oleate) as a pre-drying treatment on rate of drying, drying ratio (grape: raisin), yield and colour of raisins prepared from seedless varieties of grapes.
