Pengaruh Perbandingan Air Kelapa Dan Penambahan Daging Kelapa Muda Serta Lama Penyimpanan Terhadap Serbuk Minuman Kelapa

Abstract

Effect of coconut water and young coconut kernel ratioand storage duration to the quality of coconut waterconcentrateCoconut water and young coconut kernel have unique flavor andodour. Since these products can not be kept longer and distributionproblem, so both of them are not available everywhere and anytime.Drying method with spray dryer equipment is a method to extend theproduct life product. Generally, spray dryer is used to make some foodproducts in powder form deriving from suspension. Raw materials used inthis experiment were coconut water from both of young and mature nutand young coconut kernel. The mixture was dried with spray dryer. Theobjective of this research was to find out the effect of coconut water andyoung coconut kernel ratio to the quality of coconut water concentrateduring storage. The experiment was arranged in factorial using completelyrandomized design with 2 replications. Factor A was maturity of coconutwater consist of (A1) young coconut water and (A2) mature coconutwater. Factor B was ratio of young coconut kernel and coconut water :(B1) 15%, (B2) 20%, (B3) 25%. Factor C was : storage duration consistof (C1) 0 month, (B2) 1 month, (B3) 2 months, (B4) 3 months and (B5) 4months. The variables were observed as follow : kalium content, fibercontent, colour, flavor, odour, total plate count, acidity, total soluble solid,total acid and water content. The results showed that coconut waterconcentrate had 7.59-9.50% of total soluble solid, acidity (pH) 4.94-5.35and total acid 25.85-43.90. By using 20% young coconut kernel in maturecoconut water obtained product with fiber content about 4.70-5.54% andhighest potassium content around 1,328.58 mg/100g. Score of organoleptictest as follow : colur is 3.617-3.719 (neither like nor dislike), odour is3.00-3.96 (neither like nor dislike to like) and flavor is sweet about 2.50-3.96 (like). Total plate count of coconut water concentrate is about 3.72-4.43 log CFU/g. Maturity of coconut water affected fiber content. Addingyoung coconut kernel affected total soluble solid. Whereas interaction ofcoconut water maturity, adding coconut kernel and storage durationaffected some variables like pH, total acid, odour, flavor and total platecount. Based on the results of flavour, moisture content, potassiumcontent, fiber content and total plate count showed coconut waterconcentrate had good quality. So it is potential to be developed. The bestformula is FORMULA E which was derived from mature coconut waterwith 20% young coconut kernel
