Abstract

Fruit leather is a semi-moist food product that has a distinctive fruit flavour and a compact texture, which is not easily broken, and can be rolled up. Using purple sweet potatoes, rich in dietary fibre, can help increase the fibre content in fruit leather products. Pineapple is a commonly found fruit in Indonesia; pineapple peel is used as a by-product that is seldom used and is only thrown away; it has the potential to be a source of pectin. This study was conducted to determine the chemical, physical, microbiological, and organoleptic quality of fruit leather with the use of purple sweet potato extract with the addition of honey pineapple peel extract paste, as well as to determine the best comparison between purple sweet potato extract and honey pineapple peel extract paste. This study was conducted using the CRD method with variations of purple sweet potato extract and honey pineapple peel extract paste variations as follows: 70:0 (K), 70:3 (A), 70:6 (B), and 70:9 (C). This study showed that the use of purple sweet potato extract and honey pineapple peel extract paste had a significant effect on moisture content, ash content, insoluble fibre content, soluble fibre content, dissolved solids, texture, colour, and organoleptic properties. The fruit leather made in this study has met the TPC and Yeast Mould Count standards regulated by the National Standardisation Agency (2008). Fruit leather with the best quality results from this study is purple sweet potato extract fruit leather with the addition of honey pineapple peel extract paste at 70:9%.

Abstract

Jelly candy is a popular treat for children, teenagers, and adults alike. The good qualities of jelly candy are its transparency, chewiness, and elasticity. Utilising Clitoria ternatea L. (butterfly pea) flower extract paste and cocoa pod extract paste (Theobroma cacao L.) to make jelly candy. This research aims to determine the quality of jelly candy with butterfly pea flower extract paste and Theobroma cacao pod extract paste in terms of its chemical, physical, microbiological, and panellist preference levels, and to determine the optimal concentration of butterfly pea flower extract paste and cocoa pod extract paste in making jelly candy. This study uses a completely randomized design with variations of butterfly pea flower extract paste and cocoa pod extract paste, 0:0 as control, 2:4, 4:6, and 6:8. Jelly candy in this research has a water content of 12.00-15.26%, a ash content of 0.12-0.35%,  the antioxidant activity of 29.93-68.19%, hardness 44.20-66.05 N, springiness 0.96-0.97, and chewing power 34.54-58.32 N. The most preferred jelly candy was treatment A, which consisted of a 2% fruit peel extract paste and 1% butterfly pea flower. The total plate count and the number of yeast moulds met the quality requirements as specified in SNI 3547.2-2008. The optimal concentration of jelly candy paste is achieved using a combination of butterfly pea flower extract paste and cacao pod extract paste, with a ratio of 2:4.
