Abstract

Fish meat are very susceptible to oxidation because a lot of unsaturated fatty acids. Processing of fish sausage with smoking will provide natural antioxidants, namely phenols contained in the components of smoke. The aim of this research was to study the antioxidant effects of liquid smoke to the oxidation stability of fish sausage catfish (Clarias gariepinus) during storage. Randomized studies using Design Group (RAK) with a liquid smoking treatment and storage time on the sausage at 60 °C. Parameter used for oxidative deterioration indicators is the peroxides value and TBARS value. The result showed that the treatment liquid can suppress oxidation during storage. Oxidation during storage of smoked sausage is lower than the oxidation of sausage without curing. Smoked sausage tended to be more stable during storage for 60 hours at 60 °C instead of sausage without curing. Key words: antioxidant, phenol, sausage, peroxides value, thibarbituric acid reactive substances

Abstract

Biskuit merupakan salah satu produk olahan pangan yang memiliki tekstur renyah dimana kebanyakan dibuat dari bahan baku tepung terigu. Salah satu potensi bahan lokal yang dapat digunakan sebagai pengganti tepung terigu adalah ubi jalar oranye dan jagung. Kedua tanaman ini mengandung karbohidrat yang tinggi serta gizi yang cukup baik sebagai bahan baku pembuatan biskuit. Kelemahan jagung sebagai bahan pembuatan biskuit yaitu adanya anti nutrisi berupa asam fitat sehingga perlu dilakukan proses pendahuluan yaitu fermentasi. Bahan tambahan yang digunakan dalam membantu memperbaiki tekstur biskuit adalah kuning telur. Tujuan dari penelitian untuk mengetahui proporsi pembuatan biskuit mengunakan tepung ubi jalar oranye, jagung fermentasi dan kuning telur. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan 2 faktor. Faktor I adalah proporsi tepung ubi jalar : tepung jagung (50:50%, 70:30%, 90:10%) dan faktor II konsentrasi kuning telur (3, 6, dan 9%). Penentuan perlakuan terbaik menggunakan metode De Garmo. Penambahan konsentrasi kuning telur menunjukkan peningkatan pada kadar air, lemak dan protein. Sedangkan, pada rerata kadar pati dan serat kasar akan menurun seiring dengan meningkatnya konsentrasi kuning telur. Perlakuan terbaik secara fisik kimia diperoleh pada perlakuan proporsi ubi jalar oranye dengan tepung jagung fermentasi 70 : 30 dan konsentrasi kuning telur 9%. Sedangkan biskuit perlakuan terbaik dari segi organoleptik diperoleh pada perlakuan proporsi ubi jalar oranye dengan tepung jagung fermentasi 50 : 50 dan konsentrasi kuning telur 3%. Faktor proporsi tepung ubi jalar oranye dan tepung jagung fermentasi serta konsentrasi kuning telur berpengaruh nyata (α = 5%) terhadap kadar protein, air, serat kasar, lemak, daya patah, pati, kecerahan serta kekuningan biskuit.

Abstract

This research was conducted to analyze sodium caseinate-phospholipids behaviour in emulsion  These substances were used synergistically as emulsifier in many food systems.  The implication of its behavior to  the changes of protein emulsifying properties was further studied. Sodium caseinate-phospholipids relationship was analyzed from the changes of adsorbed protein, adsorbed phospholipids, and casein-phospholipids complexation.  The results showed that the increasing phospholipids concentration in sodium caseinate stabilized emulsion made adsorbed protein decrease and adsorbed phospholipids increase.  These indicated the displacement of caseinate by phospholipids to adsorb at oil globule interface  The more hidrophilic casein-phospholipids complex was formed and desorbed  sodium caseinate from oil globule interface. The results of displacement and complexation were decreasing adsorbed protein, percentage of adsorbed protein, and emulsion stability index. Emulsifying activity index and interfacial area decreased up to phospholipds concentration of 1,0%, and then increased. Protein load increased up to the phospholipids concentration of 1,0% and further decreased.  These  were caused by the changes of sodium caseinate-phospholipids composi-tion at oil globule interface.   Keywords: protein emulsifying properties, displacement, compexation.

Abstract

The purified -amylase, glucoamylase and pullulanase were used for hydrolysis of arrowroot starch (Marantha arundinaceae L.) a local tuber from Indonesia. This arrowroot starch is a potential source for glucose syrup production. The amylolytic activities of α-amylase, glucoamylase (from Aspergillus niger) and pullulanase (from Bacillus licheneformis) were 90 KNU/g, 260 GAU/g and 390 ASPU/g, respectively. These enzymes were used to study their synergistic effects on the hydrolysis of arrowroot starch to glucose syrup. We have studied the effect of α-amylase concentration (0.025%, 0.045%, and 0.065% (w/w)) and incubation time (1 hour, 1,5 hours, and 2 hours) during liquefaction process that was combined with 24 hours of saccharification process using 0.08% (w/w) dextrozyme (mixture of glucoamylase and pullulanase) in the glucose  syrup production.  This experiment showed that 1.5 hours of liquefaction process using 0.045% (w/w) of -amylase produced 24.64% of reducing sugar and 91.80 of dextrose equivalent.  The second experiment was focused on the determination of saccharification process, where 1 hour liquefaction process using 0.045% (w/w) of -amylase was combined with saccharification process using dextrozyme. In the saccharification process,  a various dextrozyme concentrations (0.04, 0.06, and 0.08 % (w/w)) and incubation times (24 hours, 48 hours, 72 hours) were studied in relation to glucose syrup production.  It was showed that 0.08% (w/w) of dextrozyme and 24 hours of incubation time gave the best result on glucose syrup with 24.88% of reducing sugar and 92.14 of dextrose equivalent.Keywords: arrowroot, -amylase, dextrozyme, liquefaction, saccharification, glucose syrup

Abstract

Some species of fish are known to be potential source of w-3 fatty acid, one of the essential fatty acids from human body. However, in many cases, the concentration of such fatty acids in the fish oil is quite low, and therefore, a method is needed to make it into a concentrate. One of the methods widely use is urea crystallization technique. Principally, this method is based on the inability of urea to form a complex with w-3 fatty acid, while other fractions are precipitated. This method is claimed to be able to increase w-3 fatty acids content up to 80%. Factors that influence the technique are temperature, crystallization time, and urea to oil ratio. An optimation of processing parameters for particular type of fish oil must be defined to obtain a high w-3 fatty acid concentrate.   Keywords: w-3 fatty acid, concentrate, urea crystallization

Abstract

Keluwak (Pangium edule Reinw.) is one of the Indonesian traditional spices that has spesific colour, taste, and flavour.  Keluwak seeds contain antioxidant such as tocopherol, tocotrienol, and phenolic compounds.  The utilization of keluwak traditionally has limitation due to short shelf life, time consuming preparation, and voluminous.  Preparation of keluwak in the powder form can resolve these problems.  However, the functional properties of keluwak as the source of antioxidant should be considered. The objectives of this research were to study the antioxidant stability during drying at keluwak powder preparation and the stability of antioxidant of keluwak powder during cooking.  At keluwak powder preparation, two factors were elucidated i.e. drying method (foam mat drying and non foam mat drying) and maltodextrin concentration (10, 20, and 30% w/w). Completely Randomized Block Design that arranged factorially was used at keluwak powder preparation.  The best treatment of keluwak powder preparation was used for the antioxidant stability assessment during cooking.  The antioxidant stability of keluwak powder assessed during cooking were method of cooking, i.e. stirring (0, 3, 6, 9 minutes) and boiling (0, 30, 60, 90 minutes).   Each treatments replicated three times.  Descriptive method was used in this step. The results showed that method of drying (foam mat and non foam mat) significantly affected phenolic content, tocopherol concentration, antioxidant activity, and yield of keluwak powder.  The best keluwak powder produced (physico-chemical properties) was obtained from the combination of non foam-mat drying and 10% of maltodextrin concentration. It had 19.19 ppm of total phenol, 252.2 ppm of tocopherol, 76.67% of antioxidant activity, and 36.65% of yield. Stability of antioxidant activity keluwak powder decreased as time of heating (stiring and boiling) increased proportionally.Keywords: keluwak, antioxidant activity, foam mat drying, antioxidant stability
