| Abstract | Component parts and proximate compositions of coconuts were determined. Extraction of coconut milk was studied using room temperature water at five different proportions of water to shredded coconut meat. The ratio of 1:4 water to coconut meat was used in the experiments which produced coconut milk of 32% total solid. The total solid and its concentrate was directly proportional to the refractive index. The relationship of water to coconut meat ratio and totao solid, fat content, yield or recovery of fat were formulated for prediction of these variables. The optimum feed concentration and inlet air temperature were determined. It is found that the feed concentration of 30-40% was in good range to feed to the atomizer, The optimum inlet air temperature ranged from 150-200 degree C, Incorporation of ammonium hydrogen carbonate to feed equivalent to 1.0 lit carbon dioxide/kg feed gave an improvement in recovery and bulk density. Combination of varying amount of sodium caseinate and dextrin were investigated, It appears that the product of 4% caseinate in combination with 15% dextrin and 8% caseinate with 5% dextrin were satisfactory. Lactose can replace dextrin without changing the product quality. In replace dextrin without changing the product quality. In using dairy skim milk powder, it is found to be poorer than sodium caseinate. An improvement in recovery and product quality was shown with the combination of 10% sugar syrup and caseinate 4 and 8% incorporated with ammonium hydrogen carbonate, The cost estimation for this formula was 171 B/1 kg spray dried coconut milk, The product was used as an ingredient to substitute fresh coconut milk in some desserts and the result was satisfactory. |
