Abstract

This study was aimed to develop and investigate the characteristics of the intelligent films made from gelatin with oleic acid (OA) and anthocyanin extract incorporation. Anthocyanin was extracted from red cabbage (RC), sweet potato (SP), black bean coat seed (BB), and purple rice (CR), and then tested for pH sensitivity. Anthocyanin from SP was selected as it showed the highest pH sensitivity. Gelatin film was incorporated with 20% of anthocyanin extract and 50% OA. The films with OA and anthocyanin extracts incorporation was selected for application as the color changes can be observed clearly at pH 2-11. Red color was present on the film added with anthocyanin extract from SP. OA incorporation significantly decreased the elongation of the film, while it was on the contrary for anthocyanin extract incorporation. Both OA and anthocyanin extracts incorporation decreased thickness, moisture content, and tensile strength of the film significantly (P<0.05). Additionally, there was a reduction trend of water vapor permeability for gelatin film incorporated with OA and anthocyanin. However, this reduction was insignificantly different with the control (P>0.05). The incorporation of OA provided wavier surfaces while anthocyanin extract incorporation enhanced the compactness and smoothness of the films, and provided smoother surfaces of the film. A higher enthalpy was needed for melting the film with anthocyanin extract.

Abstract

Kedelai adalah produk pangan bernilai gizi tinggi yang banyak dikonsumsi oleh masyarakat Indonesia. Pada penelitian ini, kedelai dimodifikasi dengan cara perkecambahan. Komponen zat gizi akan berubah menjadi senyawa-senyawa yang lebih sederhana selama proses perkecambahan sehingga menjadi lebih mudah dicerna bagi tubuh manusia. Selain itu, perkecambahan juga dapat meningkatkan kapasitas antioksidan. Tujuan dari penelitian ini adalah menentukan kondisi perkecambahan untuk mengoptimalkan kapasitas antioksidan dari biji kedelai varietas Wilis. Hasil penelitian menunjukkan bahwa kondisi terbaik untuk mengoptimalkan kapasitas antioksidan adalah dengan cara perkecambahan pada suhu 25°C selama 15 jam dengan rasio biji kedelai dan air 1:3 tanpa adanya penambahan garam. Kapasitas antioksidan kecambah kedelai var. Wilis pada 100 ppm memiliki radical scavenging activity sebesar 9,69% dengan scavenging ternormalisasi 0,65% dengan total fenol 2,1 mg GAE/g pada biji dan 2,9 mg GAE/g pada kecambah. Dari hasil identifikasi GC-MS ditemukan senyawa-senyawa antioksidan yang terdapat pada biji kedelai dan kecambah kedelai berupa benzoic acid, 2-methoxy-4-vinylphenol, 2,5-dihydroxytoluene, pyrogallol 1,3-dimethyl ether, 2,5-dihydroxytoluene, pyrogallol 1,3-dimethyl ether, hexadecanoic acid methyl ester dan methyl oleate serta terdapat juga senyawa-senyawa antioksidan baru yang muncul setelah proses perkecambahan yaitu neophytadiene, campesterol, stigmasterol, delta-tocopherol dan gamma-tocopherol.  ABSTRACT: Soybean is a high nutrition food product that is largely consumed by Indonesians. In this research, the soybean will be modified by going through the germination process. Complex nutrition would be changed into substances that were more simple during the germination process. Therefore, it would be easier for human to digest it. Moreover, this process might also increase the antioxidant capacity of the soybean itself. The aim of this research is to find out the most suitable germination condition in order to acquire the optimum antioxidant capacity of Wilis variety soybean. The result shows that the best condition to optimize the antioxidant capacity is by performing the germination process at 25°C for 15 hours with soybean to water ratio being 1:3 without any salt addition. The antioxidant capacity of Wilis soybean at 100 ppm has 9,69% of radical scavenging activity, with 0,65% being normalized. The total phenolic compound found in the beans was 2,1 mg GAE/g, whereas 2,9 mg GAE/g were found in the sprout. Based on the GC-MS identification, the antioxidant compounds that are found in both the soybean and sprout are known to be benzoic acid, 2-methoxy-4-vinylphenol, 2,5-dihydroxytoluene, pyrogallol 1,3-dimethyl ether, 2,5-dihydroxytoluene, pyrogallol 1,3-dimethyl ether, hexadecanoic acid methyl ester, and methyl oleate. In addition, there are also several new antioxidant compounds that emerge after the germination process, which are neophytadiene, campesterol, stigmasterol, delta-tocopherol, and gamma-tocopherol.

Abstract

Melinjo (Gnetum gnemon L.) is an Indonesian native plant which has not been widely accepted due to its limited utilization. Mainly, melinjo is consumed as an ingredient to make a vegetable dish or as raw material of ‘emping’. The purpose of this research was to study the antimicrobial activity of the melinjo seed extract and melinjo peel extract. In this study, extraction from melinjo seed and peel was conducted by maceration using three kinds of solvent: ethanol, ethyl acetate and hexane for 24 h at room temperature. The results showed that none of the melinjo extracts (concentration from 5% - 25% w/v) could inhibit the growth of Aspergillus flavus IPBCC 88.030; whereas for Bacillus cereus ATCC 10876, Staphylococcus aureus ATCC 25953, and Enterobacter aerogenes ATCC 13048 there was efficient inhibition by 5% (w/v) of melinjo seed-ethanol extract. The minimal inhibitory concentration (MIC) value of melinjo extract was ranged from 0.26 μg mL-1 to 1.46 μg mL-1, whilst the minimal bactericidal concentration (MBC) value was ranged from 1.02 μg mL-1 to 6.04 μg mL-1. The inhibitory capacity of extract had a similar level as compared to 10 ppm penicillin G on B. cereus ATCC 10876 as well as on S. aureus ATCC 25953. Furthermore, as compared to 10 ppm streptomycin, the inhibitory capacity of the extract was equal for the all tested bacteria. Cell wall deformation was observed using SEM, and confirmed by the presence of ions (Ca2+ and K+) outside of the cells, detected by means of AAS.

Abstract

Homogenization is one of the key processes in the production of UHT milk. This process is designed to reduce the size of fat globule, thus decreases the possibility of milk fat separation during storage. To ease the monitoring of successful homogenization process, homogenization degree (homodegree, oH) is commonly used instead of direct measurement of fat globule size using particle size analyser (PSA). This study was aimed to investigate the correlation between the resulted homodegree and the results of particle size analysis using PSA. There were two UHT milk variants used, A and B. Within this study, UHT milk fat globule of variant A dan B had mean diameter of 0.314 ± 0.020 μm and 0.228±0.005 μm, respectively. By this, a higher value of oH was resulted from UHT milk variant A. The homodegree was sensitive respective to the change of particle size of UHT milk for each variant. Additionally, homodegree was found to have a poor correlation, i.e., based on coefficient of determination (R2) especially for smaller size of fat globules (d10). However, this correlation was evaluated to increase for larger fat globules (d50, d90). Homodegree was also found to have poor correlation either with pressure or inlet temperature applied in homogenization. Despite some miscorrelation found between the homodegree and pressure or temperature of homogenization, measuring homodegree below 13.5 was still found sufficient to indicate successful homogenization in which UHT milk fat globule size was below 0.4 μm. Keywords: fat globule, homodegree, homogenization, particle size analysis, UHT milk

Abstract

Beras merupakan sumber karbohidrat utama bagi masyarakat Indonesia. Dalam beberapa dekade terakhir, ternyata Indonesia masih memiliki nilai impor beras yang cukup tinggi dibandingkan dengan negara berkembang lainnya yang ada dikawasan ASEAN. Kecenderungan ini mungkin dapat dilatarbelakangi oleh proses panen yang gagal (on-farm) maupun pada proses penggilingan (off-farm). Dua komponen kualitas beras hasil giling yang harus dijaga untuk dapat mempertahankan daya saing beras di pasar adalah persentase beras kepala dan derajat sosoh. Secara umum, kedua parameter diatas merupakan fungsi dari varietas gabah yang digiling, serta metode penggilingan yang terkait dengan jenis dan waktu proses penyosohan.Rice is the staple food and the main source of calorie in Indonesia. In the last few decades, Indonesia has been importing rice from ASEAN countries such as Thailand and Vietnam with significant value. This phenomenon could be caused by on-farm constraints such as crop failures or agricultural pests and even off-farm constraints, like milling process. Two important quality parameters, namely the percentage of head rice and the milling degree, have to be maintained during milling to keep the competitiveness of rice produced in the market. Generally, the values of those two parameters could be the function of paddy variety and the milling techniques which are related to the type of whitening and polishing machines used and the residence time in the machine.

Abstract

Penggunaan minyak goreng di Indonesia umumnya dipakai sebagai media panas untuk penggorengan berulang dengan jumlah minyak berlebih (deep frying). Pemilihan minyak goreng dipengaruhi oleh beberapa faktor diantaranya stabilitas terhadap oksidasi, rasa dan aspek kesehatan. Seringkali terjadi kesulitan dalam memilih karena minyak tidak jenuh yang dianggap sehat tidak tahan terhadap panas, demikian juga sebaliknya minyak jenuh yang tahan panas tidak baik bagi kesehatan. Pemilihan harus didasarkan pada penggunaannya, misalnya pada penggunaan tidak berulang maka minyak tidak jenuh merupakan pilihan yang baik. Akan tetapi jika penggunaan berulang seperti yang dilakukan di Indonesia maka minyak jenuh akan lebih baik jika dibandingkan dengan menggunakan minyak tidak jenuh.Cooking oil in Indonesia is generally used as a heat medium for repeated frying with excessive cooking oil (deep frying). Selection of cooking oil is influenced by several factors, such as stability against oxidation, taste and health aspects. The most common difficulty when choosing cooking oil is that unsaturated oil is considered healthy but not resistant to heat, and on the other hand heat resistant saturated oil is not good for health. The selection should be based on the usage, for example in the use of unrepeated frying the unsaturated oil is a good choice. However, if repeated/recurring use of oil as is the purpose, the saturated oil is better when compared to the unsaturated oil.

Abstract

Proses perkecambahan diketahui mampu memperbaiki mutu organolaptik dan juga meningkatkan beberapa senyawa tertentu pada beras pecah kulit. Artikel ini bertujuan untuk mengulas teknologi proses perkecambahan beras pecah kulit dan membahas perubahan yang terjadi selama perkecambahan. Beras pecah kulit berkecambah merupakan beras pecah kulit yang telah mengalami perendaman dan perkecambahan pada kondisi tertentu. Perkecambahan mampu meningkatkan kandungan senyawa bioaktif beras pecah kulit, salah satunya adalah senyawa γ-aminobutyric acid (GABA). GABA berfungsi sebagai penghambat neurotransmitter di otak yang bermanfaat untuk manajemen stres. Kondisi perendaman yang sesuai terkait dengan suhu, waktu, pH, maupun penambahan senyawa seperti asam glutamat dapat mengoptimalkan peningkatan kandungan GABA pada beras pecah kulit berkecambah. Selama proses perkecambahan terjadi perubahan-perubahan biokimia yang diakibatkan oleh aktivitas enzim endogenus yang mengubah komponen makromolekul menjadi komponen yang lebih sederhana. Perkecambahan pada kondisi tertentu juga dapat mengakibatkan perubahan fisikokimia pada beras pecah kulitberkecambah, diantaranya perubahan komposisi kimia, tekstur, dan profil gelatinisasi. Selain itu, perkecambahan mampu meningkatkan karakteristik organoleptik beras pecah kulit berkecambah yang telah dimasak khususnya pada atribut rasa dan tekstur.

Abstract

Tepung beras pecah kulit berkecambah dapat dimanfaatkan sebagai bahan pangan fungsional karena mengandung senyawa γ-aminobutyric acid (GABA) dan komponen bioaktif lainnya. Penelitian ini bertujuan untuk menganalisis pengaruh waktu perendaman terhadap profil pasting dan komponen bioaktif tepung beras pecah kulit berkecambah. Perkecambahan dilakukan dengan merendam beras pecah kulit selama 120 jam dengan pengambilan sampel setiap 24 jam. Tepung beras pecah kulit berkecambah mengalami penurunan viskositas puncak, breakdown, dan setback seiring dengan lama waktu perendaman. Kandungan GABA mengalami peningkatan dan mencapai nilai tertinggi setelah perendaman 72 jam. Kandungan total fenol, kapasitas antioksidan, dan γ-orizanol mengalami penurunan seiring dengan lamanya waktu perendaman. Sementara itu, hasil analisis komposisi asam lemak tepung beras pecah kulit berkecambah pada perlakuan perendaman 120 jam menunjukkan adanya dominasi asam lemak tidak jenuh. Berdasarkan hasil penelitian ini, tepung beras kecambah dengan perendaman 72 jam dapat dipilih sebagai perlakuan terbaik karena memiliki akumulasi GABA paling tinggi.
