Abstract

ABSTRAK Jambu biji (Psidium guajava Linn) merupakan tanaman tropis yang mengandung vitamin, mineral, serat, dan antioksidan. Kandungan dalam 100 gram buah jambu biji merah vitamin C sebanyak 87 mg. Jambu biji dapat dikonsumsi secara langsung maupun diolah menjadi jus, selai, jelly, manisan buah kering, dan inovasi baru seperti selai lembaran. Selai lembaran merupakan produk modifikasi selai yang mulanya dikemas dalam jar menjadi lembaran yang kompak dan plastis. Prinsip pembuatan selai adalah pemanasan dari hancuran buah, pektin atau bahan pengental, gula, dan asam. Pektin berfungsi untuk mengentalkan selai. Jumlah pektin yang ideal untuk pembentukan gel pada selai berkisar 0,75 – 1,5 %. Tujuan dari penelitian ini menentukan konsentrasi pektin yang tepat agar mendapatkan karakteristik yang sesuai pada pembuatan selai lembaran jambu biji. Rancangan penelitian yang digunakan adalah Rancangan Acak Kelompok (RAK) dengan empat perlakuan dan tiga kali ulangan sehingga mendapatkan 12 unit percobaan, dengan perbedaan konsentrasi pektin 0,75%, 0,90%, 1%, dan 1,5%. Parameter yang diamati yaitu mutu organoleptik, kadar vitamin C, dan kapasitas antioksidan. Data dianalisis menggunakan sidik ragam, hasil organoleptik warna dan tekstur ada pengaruh sehingga dilanjutkan dengan Uji Beda Nyata Terkecil (BNT). Hasil penelitian menunjukkan bahwa produk yang disukai panelis adalah selai lembaran dengan konsentrasi pektin 1%. Berdasarkan hasil analisis mutu objektif terhadap selai lembaran jambu biji yang dihasilkan yaitu kadar vitamin C 31,7690 mg/100 gram, kapasitas antioksidan 283,34 mg/L GAEAC. Kata Kunci : jambu biji, selai lembaran, organoleptik, vitamin c, antioksidan ABSTRACT Guava (Psidium guajava Linn) is tropical plant contains vitamins, mineral, fiber, and antioxidant. The 100 grams in red fruit guava vitamin c as many as 87 mg. Guava can be consumed by directly as well as processed into juice, jam, jelly, candied fruit dry, and new innovation slice jam. Slice jam is a modification jam product which was originally packaged in a jar into a compact and plastic slice. The principle of making jam is heating a mixture of crushed fruit, pectin or thickener, sugar, and acid. Pectin functions to thicken jam. The ideal amount of pectin for gel formation in jams ranges from 0,75 – 1,5%. The purpose of this study was to determine the right pectin concentration in order to obtain the appropriate characteristics in the manufacture of guava slice jam. The study design used was a Randomized Block Design (RBD) with four treatments and three replications so as to get 12 trials. With differences in concentrations of pectin 0,75%, 0,90%, 1%, and 1,5%. The parameters observed were organoleptic quality, vitamin C levels, and antioxidant capacity. Data were analyzed using analysis of variance, if there was an influence then continued the Smallest Significant Difference Test (LSD). The results showed that the most preferred product as a whole was slice jam with a pectin concentration of 1%. Based on the results of the objective quality analysis of guava jam produced, the levels of vitamin C were 31,7690 mg/100 grams, the antioxidant capacity was 283,34 mg/L GAEAC. Keywords: guava, slice jam, organoleptic, vitamin c, antioxidant
