Abstract

Fruit leather is one of the snack foods made from fruits, in the form ofthin sheets with distinctive consistency and taste depending on the typeof fruit used. One of the fruits that can be processed into fruit leatheris the bidara fruit (Ziziphus mauritiana). To improve the texture andcolor of fruit leather, the red dragon fruit peel is added as a source ofpectin and seaweed Eucheuma cottonii as a source of kappacarrageenan because it can form gel well.The purpose of this studywas to determine the effect and get the best combination of treatmentsfrom the propoetion of bidara fruit and red dragon fruit peel and theconcentration of E. cottonii seaweed on the characteristics of fruitleather. This study used a completely randomized design (CRD)factorial pattern of 2 factors, namely the proportion of bidara fruit andred dragon fruit peel (65%:35%; 70%:30%; 75%:25%) and theconcentration of seaweed E. cottonii (0 %; 0.4%; 0.8%; 1.2%) with 2replications. The data obtained was analysis by ANOVA, if thetreatment that had a significant effect was carried out further testingusing the DMRT test. The results showed the best treatment onproportion 65% of bidara fruit and 35% of red dragon fruit peel and1.2% concentration of seaweed, its produced fruit leather withmoisture content of 15.68%; antioxidant activity of 31.80%; vitamin Clevels of 30.78 mg/100 g; anthocyanin of 3.30 mg/100 g; tensilestrength of 1.4130 N; color includes L* of 42.98, a* of 41.26, b* of18.06; organoleptic scoring test includes taste of 3.16 (slightly soursweet), color of 4.92 (red), texture of 2.36 (not soft); and dietary fiberlevels of 4.06%Fruit leather is one of the snack foods made from fruits, in the form ofthin sheets with distinctive consistency and taste depending on the typeof fruit used.

Abstract

Jelly drink is a gel-based beverage product, which can be made from hydrocolloid compounds by addition of sugars, acids, and or without other food additives, sinbiotics are a combination of probiotics and prebiotics. The purpose of this study was to determine the effect concentration of carrageenan and fermentation timt on the quality of jelly drink sinbiotik soy milk and red dragon fruit extract. The method used in this research is Completely Randomized Design with two factors. The first factor was the concentration of carrageenan (0.4%, 0.6%, 0.8%) and the second factor of fermentation time (18 hours, 20 hours, 22 hours and 24 hours). To know the difference between treatments used Duncan Multiple Range Test (DMRT 5%). The results showed that the best treatment was the addition of carrageenan 0,8% and the  fermentation time of 24 hours which resulted jelly drink sinbiotik with pH value 3,7, total acid 1,02%, total lactic acid bacteria (BAL) 11,13 log cfu/ml, total sugar 7.92%, 1.89% dissolved protein, total anthocyanin 0.645% and gel strength 3.27 N.
