Abstract

Daun rambutan Aceh (Nephelum lappaceum L) mengandung senyawa yang memiliki potensi sebagai antioksidan, sehingga dapat digunakan sebagai teh herbal. Kerusakan senyawa tersebut dapat terjadi jika suhu dan waktu pengeringan tidak tepat. Tujuan penelitian ini adalah untuk mengetahui pengaruh variasi suhu dan waktu pengeringan terhadap karakteristik teh herbal dari daun rambutan Aceh. Penelitian ini menggunakan rancangan acak kelompok (RAK) dengan dua faktor, yaitu variasi suhu (40, 50, 60 °C) dan waktu (120, 150, 180 menit) pengeringan. Variabel yang diamati meliputi karakteristik kimia, seperti fitokimia secara kualitatif, total fenol, aktivitas antioksidan, dan kadar air. Data yang diperoleh diolah menggunakan analisis varian (ANOVA), dan dilakukan uji lanjut dengan uji DMRT untuk hasil yang signifikan. Teh herbal dari daun rambutan Aceh terbukti mengandung saponin, flavonoid, dan tanin. Sampel yang mengalami perlakuan suhu 50 °C selama 120 menit menunjukkan hasil terbaik, dengan kadar air sebesar 7.6%, total fenol sebesar 1.419 mg GAE/g, dan IC50 sebesar 34.106 ppm. Hasil analisis menunjukkan bahwa variasi waktu pengeringan dan suhu pengeringan memiliki pengaruh yang signifikan terhadap karakteristik kimia teh herbal dari daun rambutan Aceh.

Abstract

Sorghum is one of the local commodities that has the potential to be developed into alternative food products. Sorghum is a gluten-free source of protein, vitamins, minerals and calories. This study aims to determine the effect of the proportion of sorghum flour and sago flour on physical and chemical characteristics and determine the best treatment for dry noodles. The experimental design used a completely randomised design with one factor, that is the proportion of sorghum flour and sago flour consisting of 6 levels (80:20; 75:25; 70:30; 65:35; 60:40; 55:45) grams. The results showed that the proportion of sorghum flour and sago flour affected the physical characteristics of colour, breakage, elongation, cooking time, cooking shrinkage, and water absorption, but had no effect on breaking point. The best behaviour was produced in the proportion of 60 grams of white sorghum flour and 40 grams of sago flour which was then chemically analysed to have a moisture content of 11.90%, fat content of 0.24, ash content of 1.15%, protein content of 5.98%, and carbohydrate content of 80.79%.

Abstract

Milk is a food product that contains many nutrients. Thermosonication is a method combining ultrasonic and medium-temperature heating that can be used as an alternative pasteurisation method because it can maintain the nutrients contained in milk while providing safety assurance for consumption. This study aimed to determine the effect of frequency and duration of thermosonication on the physical, chemical and microbiological quality of cow's milk. The experimental design used was a completely randomised design (CRD) with two factorials of frequency (20 and 22kHz) and duration of thermosonication (5, 10, 15 and 20 minutes). The data obtained were analysed with ANOVA and BNJ further tests at the 5% level. The best treatment was 22kHz frequency for 20 minutes with the results of viscosity 3.80 ± 0.000 cP, pH 6.8 ± 0.00, fat content 3.22 ± 0.00%, protein content 2.19 ± 0.01% and total bacteria 0.53 ± 0.67 log CFU/ml, and was able to reduce Escherichia coli bacteria by 2.95 log CFU/ml.

Abstract

Tiwul semakin sulit ditemui karena proses pembuatan dan pemasakannya yang cukup memakan waktu, kandungan gizi pada tiwul dinilai masih rendah. Tujuan penelitian ini adalah untuk mengetahui pengaruh subtitusi tepung kecambah kacang tunggak dan penambahan xanthan gum pada pembuatan tiwul instan yang dihasilkan. Rancangan percobaan yang digunakan adalah RAL dengan dua faktor. Faktor I adalah subtitusi tepung kecambah kacang tunggak (15%,20%,25%), sedangkan faktor II adalah penambahan xanthan gum (1%, 1.5%, 2%). Perlakuan terbaik diperoleh pada subtitusi tepung kecambah kacang tunggak sebesar 20% dan penambahan xanthan gum sebesar 1.5% yang menghasilkan tiwul instan dengan karakteristik: kadar air 9,00%, kadar abu 1,84%, kadar protein 6,75%, kadar pati 73,45%, kadar amilosa 25,54%, volume kembang 126,06%, daya rehidrasi 115,22%, serat pangan 10,19%, daya cerna protein 22,43%. Sifat fisikokimia tiwul instan dapat dipengaruhi oleh formulasi subtitusi tepung kecambah kacang tunggak dan penambahan xanthan gum.

Abstract

Jackfruit seed flour (Artocarpus heterophyllus) can be used as a substitute for wheat flour in noodles production due to its high starch content and nutritional value. In addition, carrot flour is another ingredient that can be used in the production of dry noodles. The aim of this study was to determine the effect of the proportion of wheat flour, jackfruit seed flour and carrot flour, together with the supply of eggs, on the quality of the dry noodles produced. The experimental design used was Completely Randomized Design with two factors and three replications. Factor I was the ratio of wheat flour: jackfruit seed flour: carrot flour (90:5:5, 80:15:5, 70:25:5). Factor II was the addition of egg (5%, 10% and 15%). The best treatment was dry noodles made of 90% wheat flour: 5% jackfruit seed flour: 5% carrot flour and 15% egg addition, which gave the results of moisture content 7.71%, ash content 2.34%, protein content 10.68%, starch content 64.18%, amylose content 24.29%, rehydration power 55.66%, cooking loss 6.07%, elasticity 8.17%; favourability of colour, taste, aroma, texture 3.52, 3.44, 3.40, 3.48 (like).

Abstract

Pati jagung memiliki kestabilan tekstur yang baik dalam proses pembuatan Edible Film (EF). Ekstrak daun belimbing wuluh yang ditambahkan dalam pembuatan EF ditujukan untuk meningkatkan kualitas EF, dikarenakan ekstrak daun belimbing wuluh mengandung flavonoid, tannin, dan saponin. Penambahan konsentrasi pati jagung akan mempengaruhi karakteristik fisik EF. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh perbedaan konsentrasi pati jagung (rasio 1, 2, dan 3% b/v) terhadap karakteristik fisik EF. Metode eksperimental laboratorium digunakan dalam penelitian ini. Beberapa parameter yang diamati dalam penelitian ini adalah rendemen pengeringan, kelarutan, dan laju transmisi uap air. Berdasarkan parameter tersebut, perlakuan terbaik dalam penambahan pati jagung adalah sebanyak 3% b/v, dimana memiliki nilai kelarutan dan laju transmisi uap terendah secara berurutan adalah 36.68% dan 2.24g/m2.jam. Berdasarkan penelitian ini, semakin tinggi konsentrasi pati jagung dalam pembuatan EF, akan diperoleh karakteristik fisik EF yang terbaik.
