Abstract

California’s papaya is a tropical fruit that has a high nutritional content such as vitamin A and C. The fruit is quickly damaged cause have high ethylene produced. One material that can absorb ethylene gas that is KMnO4 . The purpose of this study is to determine the effect of the use of potassium permanganate (KMnO4) to some quality components California’s papaya (Carica papaya L.) during storage. The method used is an experimental method and arranged with a completely randomized design with three replications of two factors. The factor investigated was the KMnO4 concentration of 0%, 15%, and 30% and storage time of papaya for 0 day, 7 days and 14 days. Data was analyzed with analysis of variance and continued with Honestly Significant Difference (HSD) test at at 5% significance level. The parameters of experimental were weight loss, texture, moisture content, vitamin C, total dissolved solids, organoleptic test scoring (fruit skin color, flesh color and taste of the fruit). The results showed that the no interaction between the factors KMnO4 concentration and storage time. The KMnO4 concentration had no significantly effect on parameter but the texture. The storage time had significant effect on weight loss, texture, moisture content , vitamin C, fruit skin color and taste, but no effect on total dissolved solids and flesh color of papaya California. The KMnO4 concentration of 15% had the highest score on texture of papaya. The quality of California papaya had slight changed for 14 days of storage time on ambient temprature. Key words: papaya, ethylene, KMnO4, storage time ABSTRAK Buah pepaya California merupakan buah tropis yang memiliki kandungan gizi yang tinggi seperti vitamin A dan C. Buah ini cepat mengalami kerusakan karena etilen yang diproduksi tinggi. Salah satu bahan yang dapat menyerap gas etilen yaitu KMnO4. Tujuan penelitian ini yaitu untuk mengetahui pengaruh penggunaan Kalium permanganat (KMnO4) dan lama penyimpanan suhu kamar terhadap beberapa komponen mutu buah pepaya California (Carica papaya L.) yang dipanen pada tingkat kematangan 30%. Metode yang digunakan dalam penelitian ini adalah metode ekperimental di laboratorium. Percobaan ditata dengan rancangan acak lengkap 2 faktor dengan 3 ulangan. Faktor yang di teliti adalah faktor konsentrasi KMnO4 (0%, 15%, 30%) dan faktor lama penyimpanan (0 hari, 7 hari dan 14 hari). Data dianalisis menggunakan analisis keragaman pada taraf nyata 5 persen dan diuji lanjut dengan uji lanjut beda nyata jujur (BNJ) pada taraf nyata yang sama. Parameter yang diamati mencakup susut berat, tekstur, kadar air, vitamin C, total padatan terlarut, uji organoleptik scoring (warna kulit buah, warna daging buah dan rasa buah). Hasil penelitian menunjukkan bahwa interaksi antara faktor konsentrasi KMnO4 dan faktor lama penyimpanan tidak memberikan pengaruh terhadap semua parameter. Konsentrasi KMnO4, hanya berpengaruh terhadap tektur buah, sementara itu faktor lama penyimpanan berpengaruh terhadap susut berat, tekstur, kadar air, kadar vitamin C, warna kulit buah dan rasa buah pepaya California namun tidak berpengaruh terhadap total padatan terlarut dan warna daging buah. Konsentrasi KMnO4 15% memberikan skor tertinggi terhadap tekstur buah pepaya California. Penyimpanan selama 14 hari masih mampu mempertahankan mutu buah pepaya California.

Abstract

Wet noodle are food products that originally made from wheat flour with or without the addition of other ingredients and food additives. However, the main ingredient of wheat flour has nutritional value and low fiber content. The research aim was to investigate the best proportion of the wheat flour, banana blossom and seaweed of Eucheuma cottonii flour on a wet noodles quality. The experiments were conducted in laboratory and arranged with a Completely Randomized Design of single factor namely substitution of banana blossom flour with 5 types of proportions consisting 3 types of flour were wheat flour: banana blossom flour: seaweed flour with a ratio of 100 :0:0 (P0), 80:10:10 (P1), 70 :20 :10 (P2), 60:30 :10 (P3), 50:40:10 (P4), and 40:50:10 (P5) and three replications to obtain 18 experimental units. Data were analysed with analyses of variance at 5 percent of significancy and the post hoc test with Least Significant Difference Test (LSD). The results showed that the proportion affected significantly on all parameters of wet noodle quality. The best quality of a wet noodle were obtained from the proportion of 80 percent of wheat flour, 10% banana blossom flour and 10% of seaweed flour. The wet noodle had moisture, ash, protein, crude fiber, cooking loss, water absorption, L value and 0Hue of 31.38%, 1.28%, 5.4%, 1.69%, 47.23, 34.78 and 72.83 respectively. However, the sensory attributes were not preferred.
