Abstract

Tongka langit banana peel is an organic waste that has not been widely used by the community and has a pectin content of about 10.41%. Pectin extraction from banana peels should thus be done effectively to utilize waste. The objective of this research was to characterize the properties of pectin extracted from banana tongka langit peel with the different extraction times. A completely randomized experimental design with 3 level treatment extraction time of banana tongka langit peel, i.e., 1 hour, 1,5 hours, and 2 hours with three replicates was applied in this research. The properties evaluated, including equivalent weight, methoxyl content, galacturonate acid, esterification degree, yield, moisture content, and ash content. Result showed that equivalent weight (757.88 mg, 735.48 mg, and 699.8 mg), methoxyl content (5.10%, 5.17%, and 5.44%), galacturonate acid (52.22%, 53.32%, and 56.08%), esterification degree (55.07%, 55.12%, and 55.43%), moisture content (9.99%, 9.90%, and 9.85%), ash (6.17%, 6.23%, and 6,46%), and yield (8.35%, 8.93%, and 9.2%). Keywords: banana tongka langit peel, pectin, extraction time ABSTRAK Kulit pisang tongka langit merupakan limbah organik yang belum banyak dimanfaatkan oleh masyarakat dan memiliki kandungan pektin sebanyak 10,41%. Ekstraksi pektin dari kulit pisang tongka langit harus dilakukan secara efektif dalam memanfaatkan limbah. Penelitian ini bertujuan untuk mengkarakterisasi pektin kulit pisang tongka langit berdasarkan waktu ekstraksi pektin yang berbeda. Penelitian ini menggunakan Rancangan Acak Lengkap yang terdiri dari tiga tingkat perlakuan waktu ekstraksi pektin kulit pisang tongka langit yaitu 1 jam, 1,5 jam, dan 2 jam dengan 3 kali ulangan. Pengamatan dilakukan terhadap berat ekuivalen, kadar metoksil, kadar asam galakturonat, derajat esterifikasi, rendemen, kadar air, dan kadar abu. Hasil penelitian menunjukkan nilai berat ekuivalen (757,88% mg, 735,48 mg, dan 699,80 mg), kadar metoksil (5,10%, 5,17%, dan 5,44%), kadar asam galakturonat (52,22%, 53,32%, dan 56,08%), nilai derajat esterifikasi (55,07%, 55,12%, dan 55,43%), kadar air (9,99%, 9,90%, dan 9,85%), kadar abu (6,17%, 6,23%, dan 6,46%), dan rendemen (8,35%, 8,93%, dan 9,2%).

Abstract

Nutmeg is an export commodity that can be utilized in the food or beverage industries. Only a small portion of the nutmeg flesh is used, so the remainder is discarded as waste. Nutmeg pulp waste can be used to make an instant nutmeg powdered drink. Processing instant nutmeg drinks requires fillers such as maltodextrin to expedite drying and protect the raw materials from damage. This study aimed to determine the best maltodextrin concentration on an instant nutmeg drink's physicochemical and sensory characteristics. In this research, a completely randomized experimental design with four levels of maltodextrin treatment, including 10, 15, 20, and 25%, replicated twice, was applied. The result showed that the best treatment was a concentration of 25% because it had a moisture content of 7.42%, a vitamin C of 16.74%, a yield of 22.13%, and a water absorption of 11.50%. The sensory analysis showed that a maltodextrin concentration of 2% was slightly liked for its slightly brownish yellow color, slightly liked for its slight nutmeg aroma, and liked for its nutmeg taste.

Abstract

This study aimed to analyze the functional properties of pregelatinized tongka langit banana flour (TPTLP) at different maturity levels and to determine the effect of substituting TPTLP on the physicochemical properties of cookies at the optimal maturity level. This study was designed using a completely randomized design consisting of one factor, with substitution treatments of wheat flour (TT) and TPTLP, consisting of 0%: 100%, 25%: 75%, 50%: 50%, 75%: 25%, and 100%: 0% with two replications. The parameters analyzed included the water absorption capacity, vitamin A content, and antioxidant activity of TPTLP, as well as the moisture content, ash content, protein content, fat content, crude fiber, carbohydrates, breaking strength, and crispness of the cookies. The results showed that tongka langit bananas at maturity level II exhibited better functional properties than those at level I. Furthermore, substitution with TPTLP (100%, 75%, 50%, 25%, and 0%) from maturity level II significantly affected the physicochemical properties of cookies. Increasing levels of TPTLP substitution led to higher moisture, ash, and crude fiber contents, while protein content, breaking strength, and crispness decreased.
