Abstract
Pineapple’s core and peel is a waste that is not utilized, but still has a fairly high nutritional content including carbohydrates and proteins, as well as containing phenolic compunds and flavonoids. Utilization of pineapple’s core and peel waste by processing it into fruit leather to increase its economic value. This study aimed to determine the effect of the proportion of pineapple’s core and peel and carrageenan levels addition on the characteristics of fruit leather. This study used a factorial Completely Randomized Design (CDR) with 2 factors and 2 repetitions. Factor I was the proportion of pineapple’s core and peel (b/b) (60:40, 50:50, 40:60) and factor II was the concentration of carrageenan (0.6%, 0.8%, 1%). The data obtained were analyzed using ANOVA, and if there was a significant difference between treatments, it was continued with the DMRT follow-up test at a significance level of 5%. The results showed that the proportion of 50:50 pineapple’s core and peel with 1% of carrageenan concentration was the best treatment of fruit leather with water content 16.26%, sugar reduction content 24.83%, vitamin C levels 15.37 mg/100g, antioxidant activity 27.37%, crude fiber content 3.08%, tensile strength 3.02 N, total dietary fiber content 20.21% and sensory evaluation with hedonic test of color 3.52 (neutral), taste 3.44 (neutral), aroma 3.24 (neutral), and texture 3.36 (neutral). keywords: fruit leather, pineapple’s core, pineapple’s peel, pineapple, carrageenan
