Tempoyak powder is a fermented product of durian meat which is traditionally mixed with salt which is further processed through a fermentation process during storage. Maltodextrin is one of food additive, mainly used as a filler and emulsifier used in the manufacture of food powders because it has many functions in accelerating the drying process, helping in dispersing and trapping flavor of food products. This study aims to determine the best maltodextrin concentration against the physicochemical and organoleptic properties of tempoyak powder. This research was carried used a completely randomized design (CRD) with 6 treatment levels of maltodextrin concentrations which are 0, 5, 10, 15, 20 and 25% respectively, each treatment was repeated 3 times. Tempoyak powder was taken image using a scanning electron microscope (SEM) with JEOL JSM 6510 LA model. The results showed that the concentration of maltodextrin had a significant effect on yield, moisture content, color, total dissolved solids, pH, color organoleptic test, aroma and overall acceptance. The best maltodesktrin concentration in tempoyak powder is a concentration of 20% with a score of 4.16 (yellow) color, aroma 4.28 (typical tempoyak), taste 4.08 (sour) and an overall rating of 3.52 (somewhat like) which results in yield value 38.24%, moisture content 12.5781%, L value 43.61, oHue value 72.96 with a description of the color yellow red, total dissolved solids 67.67oBrix and pH 5.28.
Abstract—Coffee quality can depend on several factors such as the species/varieties cultivated, the processing after the harvesting phase, geographical origin, and climatic factors. Fermentation is one of the post harvest technology that influence coffee chemical and sensory properties. This study was to determine the effect of fermentation time into antioxidant and physicochemical of Arabica coffee from Kerinci region Indonesia. Research design used was randomized complete design with 5 combinations of treatments, which are 12, 20, 28, 36, and 44 hours fermentation with 3 replicates. The results shows fermentation time have a significant effects on moisture content, pH, antioxidant activity. The duration of fermentation results in increasing higher moisture content, lower pH value and decreased antioxidants. Keywords— Anaerobic fermentation, coffee processing, antioxidan
Tujuan dari program pengabdian pada masyarakat ini adalah menciptakan kemandirian ibu-ibu Desa agar dapat berinovasi dan berkreativitas dalam memanfaatkan hasil samping perkebunannya, sehingga dapat menghasilkan produk yang dapat menambah pendapatan rumah tangga. Guna mencapai tujuan ini, diperlukan transfer teknologi kepada ibu-ibu pedesaan melalui pengolahan biji karet menjadi produk tortilla chip. Metode yang dilakukan dalam pelaksanaan kegiatan PPM ini adalah: (1) Sosialisasi cara mereduksi HCN biji karet sebelum dibuat tepung biji karet, (2) Demo langsung kepada ibu-ibu tentang cara pembuatan tortilla chip dengan memanfaatkan tepung biji karet, (3) memberikan Teknik pemasaran dan melatih cara pengemasan produk.
Tujuan dari penelitian ini adalah untuk mengetahui pengaruh asam sitrat dalam ekstraksi antosianin bunga kembang sepatu. penelitian ini dilakukan menggunakan rancangan acak lengkap yang terdri dari 5 taraf perlakuan asam sitrat yaitu 0%, 3%, 5%, 7% dan 9%. Data di analisis menggunakan Analisys of Varian (ANOVA) dan uji lanjut Duncan Multiple Range Test (DMRT) pada taraf kepercayaan 95%. Hasil penelitian menunjukkan bahwa penggunaan asam sitrat berpengaruh nyata terhadap rendemen, pH, warna dan konsentrasi antosianin. perlakuan asam sitrat 9% merupakan perlakuan terbaik dengan rendemen 75,12%; pH 3,23; L 40,33; A 58,00; B 30,33 dengan deskripsi warna dark red dan kadar antosianin sebesar 135,04 (mg cyaniding 3-glukosida/100 g bahan).
Penelitian ini bertujuan untuk mengetahui pengaruh lama fermentasi menggunakan cairan kubis fermentasi (sauerkraut) terhadap sifat fisikokimia dan fungsional tepung uwi kuning (Dioscorea spp.). Cairan sauerkraut hari ke-3 (72 jam fermentasi) sebagai sumber Bakteri Asam Laktat (BAL) digunakan dalam proses fermentasi. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan 6 taraf perlakuan, yaitu tanpa fermentasi (kontrol), 12, 24, 36, 48, dan 60 jam fermentasi. Penelitian dilakukan dalam dua tahap yaitu pembuatan cairan sauerkraut dan pembuatan tepung fermentasi. Cairan sauerkraut mengalami peningkatan total mikroba dan penurunan nilai pH seiring dengan lamanya fermentasi. Pada cairan fermentasi uwi terjadi peningkatan total mikroba dan penurunan pH selama 48 jam fermentasi. Fermentasi lebih dari 48 jam mengakibatkan jumlah mikroba menurun kembali. Hasil penelitian menunjukkan bahwa lama fermentasi memiliki pengaruh (p ≤ 0,05) terhadap nilai kromatik warna b* 25,95 (48 jam), solubility pada titik suhu 65 °C dan 75 °C, kapasitas penyerapan air 2,28 g/g (60 jam), dan aktivitas antioksidan 67,68% (60 jam), namun tidak berpengaruh (p ≥ 0,05) pada kadar air, kadar serat, nilai kromatik warna L* dan a*, °hue, swelling power, solubility dibeberapa titik suhu (70, 80, 85, 90, 95 °C), kapasitas penyerapan minyak, dan aktivitas emulsi.
