Nadhiro, Fia Aminatun and Suprayogi,, STP, M.Si, PhD and Dr. Ir. Nur Hidayat,, M.P. (2022) Pengaruh Pemberian Edible Coating Dari Kombinasi Pati Jagung (Amilum Maydis) Dan Pati Biji Alpukat (Persea Americana Mill) Terhadap Kualitas Umur Simpan Cabai Rawit (CAPSICUM FRUTESCENS L.). Sarjana thesis, Universitas Brawijaya.
Abstract
Cabai rawit (Capsicum Frutescens L.) merupakan salah satu tanaman hortikultura yang rentan mengalami kerusakan serta memiliki umur simpan yang cukup rendah yaitu sekitar 2-3 hari pada suhu ruang. Kerusakan dan pendeknya masa simpan tersebut tidak bisa dihentikan namun dapat dikurangi dengan menggunakan edible coating. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian edible coating berbahan dasar kombinasi pati jagung (Amilum Maydis) dan pati biji alpukat (Persea Americana Mill) yang ditambahkan dengan Gliserol (C3H8O3) dan Kitosan pada umur simpan dan sifat fisik dari cabai rawit (Capsicum Frutescens L.). Penelitian ini menggunakan metode Response Surface Methodology (RSM) yang terdiri dari dua faktor yaitu pati jagung dan pati biji alpukat. Parameter yang diamati dalam penelitian ini yaitu kadar air, susut bobot, kekerasan dan organoleptik. Data organoleptik di analisis menggunakan uji Friedman. Penentuan perlakuan terbaik pada uji organoleptik dilakukan dengan menggunakan indeks efektivitas. Hasil penelitian menunjukkan bahwa pemberian edible coating berbahan dasar pati jagung (Amilum Maydis) dan pati biji alpukat (Persea Americana Mill) yang ditambahkan dengan gliserol dan kitosan berpengaruh terhadap sifat fisik dan umur simpan cabai rawit selama 8 hari. Konsentrasi formula edible coating terbaik yaitu konsentrasi pati jagung 10 gr dan pati biji alpukat 2,4 gr dimana tertera pada sampel ke-2 dengan nilai kekerasan 0,238 kg/cm2 , susut bobot 2,226%, kadar air 69,402% dan desirability 0,562 dengan keterangan suggested yang berarti model konsentrasi ini lebih disarankan dibandingkan dengan model yang lainnya
English Abstract
Chili pepper (Capsicum Frutescens L.) is one of the horticultural plants that are susceptible to damage and has a low shelf life of about 2-3 days at room temperature. The damage and the short shelf life cannot be stopped but can be reduced by using edible coatings. The edible coating materials used in this study were corn starch (Amilum Maydis), avocado seed starch (Persea Americana Mill) with glycerol (C3H8O3) as a flexible plasticizer and chitosan as an antimicrobial agent. This study aims to determine the effect of giving edible coatings made from a combination of corn starch (Amilum Maydis) and avocado seed starch (Persea Americana Mill) added with glycerol (C3H8O3) and chitosan on the shelf life and physical properties of chili pepper (Capsicum Frutescens L.). The study consisted of 13 treatment combinations which were a combination of the weight of corn starch and avocado seed starch. This study uses the Response Surface Method (RSM) method which consists of two factors, corn starch, and avocado seed starch. Parameters observed in this study were water content, weight loss, hardness, and organoleptic. Organoleptic data were analyzed using the Friedman test. Meanwhile the determination of the best treatment in the organoleptic test was analyzed using the effectiveness index. The results showed that the application of edible coating made from corn starch (Amilum Maydis) and avocado seed starch (Persea Americana Mill) added with glycerol and chitosan affected the physical properties and shelf life of chili pepper for 8 days. The best concentrations of edible coating formula are corn starch concentration of 10 g and avocado seed starch of 2.4 g which is stated in the second sample with a hardness value of 0.238 kg/cm2, weight loss of 2.226%, the water of 69.402%, and desirability 0.562 with the suggested explanation. This means that this concentration model is more recommended than other models
