Abstract

ABSTRAK: Jamu kunyit asam merupakan minuman tradisional yang umum digunakan masyarakat Indonesia sebagai pengobatan alternatif. Pemanfaatan jamu kunyit asam masih terbatas sehingga diperlukan pengembangannya sebagai  produk pangan, salah satunya adalah ditambahkan dalam pembuatan es krim susu kedelai yang bertujuan agar masyarakat dengan lactose intolerant dapat mengkonsumsi es krim. Dalam penelitian ini, jamu kunyit asam dibuat dengan variasi rasio kunyit: asam: air (20:20:60; 10:30:60; 30:10:60) dan variasi waktu perebusan asam (2, 4, dan 6 menit). Selanjutnya dilakukan analisis aktivitas antioksidan, total fenolik, total flavonoid, dan warna jamu kunyit asam. Jamu kunyit asam terpilih adalah dengan perlakuan kunyit:asam:air 30:10:60 dan waktu perebusan asam 2 menit, memiliki nilai IC50 14,44%, total fenolik 0,49 mg GAE/g, total flavonoid 0,39 mg QE/g, dan nilai °Hue 51,28 . Es krim susu kedelai jamu kunyit asam dibuat dengan kontrol jamu kunyit asam 0% dan variasi penambahan jamu kunyit asam (10%, 20%, dan 30%) dan konsentrasi gelatin (0,2%; 0,3%; 0,4%). Hasil es krim dianalisis aktivitas antioksidan, total fenolik, total flavonoid, warna, waktu leleh, overrun, dan sensori. Es krim susu kedelai terpilih adalah es krim dengan penambahan jamu kunyit asam 30% dan  gelatin 0,4%. Es krim tersebut memiliki nilai IC50 49%, total fenolik 2,10 mg GAE/g, total flavonoid 0,53 mg QE/g, nilai °Hue 88,48, waktu leleh 19,26 menit, dan nilai overrun 17,87%. Es krim jamu kunyit asam terpilih tergolong es krim rendah lemak, berpotensi sebagai produk pangan yang aman bagi penderita lactose intolerant,  disukai dari analisis nilai sensori, namun tidak berpotensi sebagai sumber antioksidan. ABSTRACT: Jamu kunyit asam was a traditional drink in Indonesia and used  as an alternative medicine. However, the use of this traditional drink was still limited so it was necessary to develop as  food products, such as making soybean milk  ice cream which aims for people with lactose intolerant able to consume ice cream. Jamu kunyit asam was made by varying ratio of turmeric:tamarind:water (20:20:60; 10:30:60; 30:10:60) and variations boiling time of tamarind (2, 4, and 6 minutes). Analyzes of antioxidant activity, total phenolic, total flavonoids, and color in tamarind turmeric were carried out. Selected jamu kunyit asam was ratio of turmeric:tamarind:water 30:10:60 and  2 minutes of boiling time which has an IC50 value 14.44%, total phenolic 0,49 mg GAE/g, total flavonoid 0,39 mg QE/g, dan  °Hue value 51,28. Soybean milk ice cream with jamu kunyit asam was made by addition varying of jamu kunyit asam (10%, 20%, and 30%) and gelatin (0.2%; 0.3%; 0.4%) with control of 0% jamu kunyit asam. The selected soybean milk ice cream was ice cream with addition of 30% jamu kunyit asam and 0.4% gelatin. The ice cream had an IC50 value 49%, total phenolic 2,10 mg GAE/g, total flavonoid 0,53 mg QE/g, °Hue value 88,48, melting time 19,26 minutes, and overrun 17,87%. Selected soybean ice cream was categorized  low fat ice cream and safe to be consumed by people with lactose intolerance, and have good value in sensory analysis, but did not have potential as a source of antioxidants.

Abstract

Udang windu (Penaeus monodon) mempunyai kandungan kitin dalam jumlah cukup besar pada cangkangnya sehingga berpotensi sebagai bahan baku dalam pembuatan glukosamin. Pembuatan glukosamin dari kitin dapat dilakukan dengan hidrolisis kimia menggunakan asam klorida (HCl). Tujuan dari penelitian ini adalah untuk mengetahui efisiensi penggunaan HCl teknis pada konsentrasi, suhu dan lama pemanasan dalam produksi glukosamin. Tepung cangkang udang diperoleh dengan mengeringkan kulit udang dengan sinar matahari dan kemudian dikecilkan ukurannya. Kitin diperoleh dengan melakukan proses demineralisasi dan deproteinisasi pada tepung cangkang udang. Glukosamin diperoleh dengan menghidrolisis kitin dengan perendaman dalam larutan HCl teknis berkonsentrasi 23, 30, dan 37% dengan perbandingan 1: 9 (b / v) pada suhu 90 °C selama 4 jam. Hasil konsentrasi terbaik selanjutnya digunakan untuk menentukan suhu dan waktu pemanasan terbaik dari perlakuan 60, 70, dan 80 °C dan waktu pemanasan 2, 3, dan 4 jam. Penentuan konsentrasi terbaik dan suhu dan waktu pemanasan dipilih berdasarkan tingkat glukosamin tertinggi. Hasilnya menunjukkkan bahwa penggunaan konsentrasi HCl teknis 37% dipilih sebagai perlakuan terbaik dengan kadar glukosamin 7511,46 mg /kg. Penggunaan suhu pemanasan 80°C dan waktu pemanasan 4 jam teripilih sebagai perlakuan terbaik dengan kadar glukosamin mencapai 10519,79 mg/kg. Glukosamin yang dihasilkan mempunyai kelarutan 89,65%, pH 3,82 dan berwarna kuning kemerahan (oHue 77,16). Kata kunci: Udang windu, kitin, glukosamin, HCl teknis

Abstract

Radish (Raphanus sativus L.) root is commonly used  as flavor enhancing additive or side dish. Previous research revealed the presence of active compound in which could inhibit bacterial growth. Thus, a research concerning natural antibacterial for fish products that are categorized as high-risk food being contaminated by spoilage bacteria (Pseudomonas aeruginosa, Bacillus cereus, dan Staphylococcus aureus) was done. Radish root extraction was made by using ethyl acetate (semi polar) for 3 days. Well diffusion was performed using 4 extract concentration (10, 20, 30, dan 40% (w/v)) againts  three fish spoilage bacteria. Based on our results, 30% concentration was the best concentration which inhibit more than 10 mm in inhibition zone with MIC  and MBC. The scores were of 0.06% and 0.24% (P. aeruginosa), 0.13% and 0.50% (S. aureus), and 0.12% and 0.48% (B. cereus). Moreover, based on stability test against heating temperature showed that this extract concentrationwas more stable in 80°C with duration times for 5 minutes and pH 3 which resulting the lowest inhibition zone reduction compares to control extract. Radish extract was categorized as low toxic compound (LC50 = 839.52 ppm) functioning in antibacterial compound containing major antibacterial compound (bis(2-ethylhexyl) phthalate, 1,2-benzenedicarboxylic acid, 9,12,15-octadecatrienoic acid), fatty acid (n-hexadecanoic acid, butanedioic acid), carboxylic acid (isobutyric acid, malic acid, oleic acid), and minor antibacterial compound (n-Hydroxymethylacetamide, 2,4-bis(1,1-dimethylethyl), 2,4-pentanedione,2-Cyclohexen-1-one, hydrazine, cyclohexene oxide, gamma-sitosterol).

Abstract

Star anise (Illicium verum Hook. f.) is commonly used as spice and flavor enhancer in food. Previous research revealed the presence of active compound which could inhibit bacterial growth. Thus, in order to apply star anise as natural antibacterial agent in food product, a further research concerning antibacterial activity and stability of star anise was conducted. Crude extract of star anise was obtained using ethanol and acetone with maceration method for 3 days, then diluted to 10, 20, 30, 40, and 50% (w/v). Well diffusion was conducted against three food spoilage bacteria (Staphylococcus aureus, Escherichia coli, and Bacillus cereus). Extract from ethanol with 30% concentration was selected as the best extract in which inhibit more than 6 mm inhibition zone with MIC and MBC value: 1.59% and 6.36% (S. aureus), 1.04% and 4.18% (E. coli), and 0.59% and 2.39% (B. cereus). This selected extract was used to test the extract stability against 4 levels of heating temperature (60, 70, 80, and 90°C) for 2 levels of heating time (15 and 30 minutes), and 4 levels of pH (4, 5, 6, and 7). Based on our results, different heating treatment and pH caused extract instability. Star anise extract was more stable at 60°C for 15 minutes heating treatment and pH 4, which resulting the lowest inhibition zone reduction compared to control extract. Star anise extract was categorized as low toxic compound (LC50 = 212.09 ppm). Terpenoids (anethole, 2,6-dimethyl-6-(4-methyl-3-pentenyl)-2-norpinene, β-caryophyllene, β-bisabolene) was founded as major antibacterial compound in star anise extract; fatty acid (6-octadecenoic acid, hexadecanoic acid, stearic acid) and benzaldehyde (4-anisaldehyde, p-allylanisole) were also founded as minor compound.
