The Effect of Concentration of Caragenan and Sucrose on Characteristics of Palmyra Palm (Borassus flabellifer) Seed Juice Jelly Drink

Abstract

Objective of the research was to study the characteristics of jelly drink made of  palmyra palm endosperm juice.  Palmyra palm fruit from Tuban, East java was peeled by cracking  the hard  rind, then the juicy endosperm was extracted into ‘fruit juice’.  Treatments in this experiment  consisted of 0.1%, 0.2% and 0.3% carageenan as the first factor and 5%; 7% and 10% of Sucrose as the second factor. Data obtained was analysed by ANOVA followed by HSD 5%. Result of the research showed that there were no interaction observed between carageenan and sucrose concentration.  The higher the carageenan concentration the lower moisture and syneresis value.  The higher the sucrose concentration, the higher the total soluble solids.  Based on the data of all variables, treatment of 0.1% carageenan and 10% sucrose gave the best characters of jelly drink which has 61.37% moisture; 13.2ºBrix of TSS; pH 3.73, 10.53 syneresis value, 83.74 lightness, 0.06 redness; i.16 yellownes, and organoleptics characteristics of  aroma 5;colour 4.70; flavor 5.03; texture 4.03; and drink suction of 4.43.
