Abstract

Turmeric is widely used as a herbal medicine, food preservation and food coloring. However, food industries have less interest to utilize turmeric as a food coloring due to its spesific aroma. The objective of this research was to obtain the proper method to eliminate the turmeric’s spesific aroma. The experimental methods consisted of 3 stages, namely distillation (A1) and non-distillation (A2) methods which then was extracted by maceration method with the addition of 96% ethanol (B1), acetone (B2) and ethanol 96% + acetone (B3) as stage 1; with (C1) and without heating (C2) as stage 2; and the addition of 3% acetic acid and 3% citric acid as stage 3. The results of stage 1, 2, and 3 were the spesific aroma of turmeric tend to be weak when use the distillation and maceration with 96% ethanol where the curcumin content was 0.50%, and with the addition of 3% acetic acid which have a brighter color, respectively. The color analysis showed that the color by adding 3% acetic acid has CIE b* (yellow) of 66.85 with pH of 3.24. So, the proper method for eliminating the turmeric’s spesific aroma was distillation process then followed by extraction using 96% ethanol and adding 3% acetic acid to increase the color brightness and homogeneity.

Abstract

Buah merah merupakan buah khas Papua. Pada umumnya, buah merah dibuat minyak untuk pengobatanpenyakit. Pembuatan minyak menghasilkan limbah. Limbah tersebut masih mengandung nutrisi dan dapatdigunakan sebagai pewarna alami pada pembuatan dodol. Untuk menghasilkan dodol dengan tekstur yangbaik kita harus menambahkan hidrokoloid seperti gelatin. Ketersediaan gelatin halal saat ini sangat sedikit,karena sangat penting untuk mencari alternatif gelatin halal. Salah satu alternatif pengganti jelatin halaladalah kefir air. Penelitian dimulai dengan membuat minyak buah merah untuk diambil ampasnya. Padapenelitian ditambahkan ampas buah merah dengan berbagai konsentrasi gelatin yaitu 0,1%, 0,5%, dan 1%.Hasil analisis sensori menunjukkan bahwa falvor dan rasa tidak berpengaruh nyata, sedangkan teksturberpengaruh nyata.

Abstract

Prevalensi stunting di Indonesia menempati peringkat kelima terbesar di dunia. Data Riset kesehatan dasar (Riskesdas) tahun 2013 menunjukkan prevalensi stunting dalam lingkup nasional sebesar 37,2 persen, terdiri dari prevalensi pendek sebesar 18,0 persen dan sangat pendek sebesar 19,2 persen. Hasil Riset Kesehatan Dasar (Riskesdas) tahun 2018 menunjukkan Prevalensi stunting turun 6,4% dari 37,2% pada tahun 2013 menjadi 30,8% namun hal itu tetap menjadi masalah kesehatan karena Indonesia merupakan negara nomor empat dengan angka stunting tertinggi di dunia. Lebih kurang sebanyak 9 juta atau 37,0% balita Indonesia mengalami stunting (Widyakarya Nasional Pangan dan Gizi, 2018). Prevalensi balita stunting di provinsi Gorontalo tahun 2019 sebesar 32%. Di Kabupaten Pohuwato Tahun 2017 sebesar 33,2%, tahun 2018 sebesar 8% dan tahun 2019 sebesar 7,43%. Hasil riset kesehatan dasar terakhir prevalensi stunting di Kabupaten Pohuwato sudah masuk zona hijau tetapi masih jauh dari target yang ditetapkan yaitu 0% pada tahun 2025. Salah satu upaya penanggulangan stunting pada balita adalah dengan memberikan edukasi kepada masyarakat dalam rangka peningkatan pengetahuan dan kesadaran akan penanggulangan stunting serta edukasi dalam pemberian makanan tambahan dengan memanfaatkan bahan makanan bersumber daya lokal salah satunya jagung. Tujuan yang ingin dicapai dari kegiatan ini adalah dapat membantu meningkatkan derajat kesehatan masyarakat, meningkatkan pengetahuan, kesadaran dan kepedulian masyarakat mengenai stunting dan meningkatkan kreativitas masyarakat dalam upaya pencegahan stunting melalui pengolahan bahan pangan bergizi berbasis sumber daya pangan lokal.

Abstract

Campolay (Pouteria campechiana) has complete content of fiber, starch, calcium, phosphorus, carotenoid, thiamin, riboflavin, niacin, and vitamin C. The presence of this ingredient makes Campolay potentially an alternative functional food ingredient. Campolay processing in flour products was done to extend shelf life, improve functional properties, and diversify products, thus expanding use. Resistant starch (RS) is a starch that is not able to be digested by digestive enzyme and resistant to gastric acid that it is able to reach colon to be fermented by probiotic bacteria. RS is classified as insoluble fiber source and is able to decrease the glycemic index and cholesterol, preventing the colon cancer, and helping the absorption of mineral. The aim of this study is to produce the resistant starch of campolay flour through autoclaving-cooling cycle treatment. Slices of campolay were autoclaved (121oC, 15 minutes) and cooled (4oC, 24 hours). The treatment was done for one, two and three cycles. Then, the campolay slices were dried (70oC, 7 hours), milled and sifted (100 mesh) to obtain modified campolay flour. The modified Campolay flour was analyzed for amylose content, total starch, reducing sugar content, Rapid Digestible Starch (RDS), Slowly Digestible Starch (SDS) and Resistant Starch / RS levels, starch digestibility with three replications. The treatment of 1 cycle of autoclaving-cooling (AC-1S) resulted the highest levels of resistant starch (36.23% bk) when compared to other treatments. It could increase the resistance of starch levels by 2.4-fold compared to the control treatment (15, 31% bk).

Abstract

Talas dikenal mengandung mucilage yang memiliki sifat mirip dengan asam hialuronat penyusun gelatin.  Penelitian ini bertujuan untuk mengetahui pengaruh suhu dan waktu ekstraksi mucilage talas terhadap sifat asam hialuronat yang dihasilkan. Pada penelitian ini asam hialuronat diisolasi dengan menggunakan air destilata pada suhu 70 dan 90oC  selama 30 dan 60 menit dan dikoagulasikan menggunakan alkohol sebanyak 1:1, kemudian endapan dikering-anginkan pada suhu ruang selama 12 jam dan dilanjutkan dengan waterbath shaker pada suhu 40°C selama 30 menit. Asam hialuronat kering kemudian dihaluskan dan diayak 80 mesh, dianalisis sifat fitokimia, fisikokimia, dan sensorinya.  Asam hialuronat talas dari semua perlakuan positif mengandung karbohidrat, protein, glikosida dan gula pereduksi, tetapi tidak mengandung alkaloid dan flavonoid. Hasil uji fisikokimia menunjukkan bahwa suhu dan waktu tidak berpengaruh terhadap bulk density, tap density, dan kadar abu, tetapi berpengaruh terhadap kadar air, residu alkohol, dan pH. Asam hialuronat tidak larut dalam alkohol tetapi larut dalam air panas mulai 40°C.
