SINTESIS PATI JAGUNG TERFOSFORILASI MELALUI TEKNIK GELOMBANG MIKRO [Microwave-Assisted Synthesis of Phosphorylated Corn Starch] Atep Dian Supardan*, Suminar Setiati Achmadi dan Tun Tedja Irawadi Departemen Kimia, Fakultas Matematika dan Ilmu Pengetahuan Alam, Institut Pertanian Bogor, Bogor   Diterima 28 Maret 2013 / Disetujui 24 Februari 2014 ABSTRACT Phosphorylated starch is a type of modified starches which is mostly imported. Commonly, starch to be modified must contain more than 25% of amylose. This study aimed to synthesize phosphorylated starch and evaluate its potency as a heavy metal adsorbent. Corn starch was subjected to phosphorylation through microwave-assisted reaction with a mixture of sodium dihydrogen orthophosphate and disodium hydrogen phosphate. The experiment was designed to optimize the pH, microwave radiation power, and phosphorylation time. The results showed that the maximum phosphate subtitution degree was obtained at pH of 6, microwave radiation of 500 W, and a reaction time of 10 minutes. The degree of subtitution ranged from 0.567 to 0.787. The physicochemical properties of the product i.e. swelling capacity, solubility, water binding capacity, and paste clarity were significantly different than that of the unmodified corn starch. The infrared spectrum showed a high peak absorption at the wavelength of 1651 cm-1, indicating hydrogen bond formation of phosphoric group-water- phosphoric group. In the fingerprint area, there were two new absorption peaks at 1200 and 990 cm-1, which were assigned for the P=O and C-O-P vibrations, respectively. The phosphorylated corn starch adsorbed methylene blue up to 73.3% and mercury up to 73.6%, suggesting the prospect of the microwave-assisted synthetic phosphorylated corn starch as an effective adsorbent for heavy metals.

The aim of this research is to observe the antibacterial activity of tempe extract against Bacillus subtilis and Staphylococcus aureus. The results of this research broadens the current knowledge of tempe as functional food. Samples of commercial tempe were obtained from a traditional market of Pringgan Medan, Sumatera Utara. Tempe samples were then extracted using three solvents with different polarity: ethanol, n-hexane and ethyl acetate, each at three levels of concentration i.e. 300 mg/mL (30%), 400 mg/mL (40%) and 500 mg/mL (50%). The antibacterial activity test of tempe extracts was carried out using disc difussion method on Mueller Hinton Agar (MHA), and incubation was conducted at 36-37°C for 24 hrs. The obtained data were tested statistically with Analysis of Variant (ANOVA) p>0.05. The ethanol and ethyl acetate extracts of tempe inhibited the growth of B. subtilis and S. aureus. Meanwhile, the ethyl acetate extract of tempe at concentration of 500 mg/mL had the highest inhibition against S. aureus as shown by inhibition diameters of 15.50±0.44 mm (p>0.05), and B. subtilis at 14.13±0.21 mm (p>0.05). No inhibition observed with the n-hexane extracts of tempe against the above bacteria.

Raya Dramaga, Bogor Diterima 01 Agustus 2013 / Disetujui 05 Februari 2014 ABSTRACT Chronic Obstructive Pulmonary Disease (COPD) is one of the leading cause of death in the world that represents an important public health problem. Oxygenated water is water added with high concentration of oxygen such that the oxygen concentration is higher than normal water. The objective of this study was to assess the influence of oxygenated water consumption on the alteration of proinflammatory cytokines (TNF-α, IL1-β, and IL6) and antioxidant capacity of COPD patients. Sixteen COPD patients were allowed to drink 385 mL oxygenated water two times a day for 21 days. The alteration of proinflammatory cytokines and antioxidant capacity are measured by comparing plasma concentration before and after intervention. The results suggest that oxygenated water consumption significantly reduce proinflammatory cytokines plasma (TNF-α, IL1-β, and IL6) at 5% significance level with 81.25% of respondents having lower TNF-α, 75% of respondents with lower IL-1β, and 62.25% of respondents having lower the IL-6 in plasma concentration after 21 days intervention. There were 43.75% of respondents with decreased antioxidant capacity concentration. However, it was not significant at the 5% level significance. Decrease in antioxidant capacity was probably a resulted from poordiet and drugs consumption during the intervention period.

PENGARUH DEFATTING, FREKUENSI PENCUCIAN DAN JENIS DRYOPROTECTANT TERHADAP MUTU TEPUNG SURIMI IKAN LELE KERING BEKU [Effect of Defatting, Washing Cycle and Dryoprotectant Type on the Quality of Freeze Dried Catfish Surimi Powder] Wahyu Ramadhan*, Joko Santoso dan Wini Trilaksani Departemen Teknologi Hasil Perairan, Fakultas Perikanan dan Ilmu Kelautan, Institut Pertanian Bogor, Bogor Diterima 05 Agustus 2013 / Disetujui 08 April 2014 ABSTRACT Freeze dried surimi powder is a surimi type processed by freeze drying. To utilize oversized catfish and to reduce surimi handling cost, oversized catfish has been used as raw material of surimi powder. The study aimed to determine the effect of defatting (NaHCO3 concentration and soaking duration), washingcycle,and dryoprotectant type on catfish surimi, as well as quality differences between surimi powder and wet surimi. With regard to defatting step, soaking in NaHCO3 0.75% for 10 minutes was found as the best treatment and resulting in a fat content of 1.52%. Moreover, one time of washing cycle was found as the most appropriate procedure to obtain a superior quality of surimi with whiteness value 57.21%, water holding capacity 73.28%, salts soluble protein 7.17%, pH 6.69, and gel strength 482.3 g/cm2, folding value of 4.84, and teeth cutting value of 8.26. Trehalose 6% was the most suitable dryoprotectant resulting in surimi powder with water holding capacity of 8.01 mL/g, gel strength 826.3 g/cm2, salt soluble protein 18.98%, density 4.06 mL/10 g, rehydration capacity 3.81, emulsion capacity 69.3%, emulsion stability 59.3%, foaming capacity 25.33% and foaming stability 9.40%. The microstructure profile of surimi powder added with trehalose had more compact tissues, without any damage and clots, than that treated with other dryoprotectants. However, surimi powder still had lower protein content than wet surimi, and lower physical and chemical properties, particularly in its teeth cutting and folding characteristics.

PEMANFAATAN BAKTERI PROBIOTIK INDIGENUS DALAM PEMBUATAN KEJU LUNAK [Utilization of Indigenous Probiotic Bacteria in the Production of Soft Cheese] Fifi Afiati1)*, Yopi1) dan Rarah R.A. Maheswari2) 1) Pusat Penelitian Bioteknologi LIPI, Jl. Raya Bogor Km 46, Cibinong, Bogor 2) Departemen Ilmu dan Teknologi Peternakan, Fakultas Peternakan, Institut Pertanian Bogor, Bogor   Diterima 12 April 2013 / Disetujui 15 Februari 2014 ABSTRACT Probiotic soft cheese containing lactic acid bacteria is one of functional food products. Three lactic acid bacteria namely Lactococcus lactis DSB 42 (LL-DSB42), Lactobacillus acidophilus RRM-01 (LA-RRM01) and Bifidobacterium longum RRM-01 (BL-RRM01) were used in the production of probiotic soft cheeses. Single culture (BL, LA, and LL) and mixed culture (BL-LA, BL-LL, LA-LL and BL-LA-LL) were used to produce diversified functional products. The preparation of probiotic soft cheese consists of pasteurization, addition of lactic acid bacterial culture (5%, v/v), addition of rennet, cutting the curd, scalding, draining and packaging. Soft cheese characteristics were analyzed physically (yield), chemically (pH, water content, crude protein, crude fat and ash) and microbiologically (lactic acid bacteria). The results showed that addition of lactic acid bacteria cultures significantly decreased the pH value (pH 5.10 to 5.79). The yield of probiotic soft cheese produced was in the range of 17.86-22.51% with water content of more than 55%. The fat and carbohydrate content of both cheeses of single and mixed cultures were significantly different (p<0.05) (fat content 5.1-7.4% for single culture and 4.0-9.3% for mix culture; carbohydrate content 11.6-17.7% for single culture and 4.6-12-2% for mix culture). The combination of all three starter cultures did not result in inhibition to each other, thus these combination were able to achieve the maximum number of 9.0 log10CFU g-1 on a single culture soft cheese and 9.8 log10CFU g-1 in mixed cultures soft cheese. In conclusion, soft cheeses with single culture (BL, LA, and LL) and mixed culture (BL-LA, BL-LL, LA-LL and BL-LA-LL) had excellent potential properties to be developed as probiotic foods.

PENAMBAHAN TEPUNG PORANG PADA PEMBUATAN MI DENGAN SUBSTITUSI TEPUNG MOCAF (Modified cassava FLOUR) [Addition of Porang Flour in Noodle as Mocaf Substitution (Modified cassava Flour)] Anni Faridah1)* dan Simon Bambang Widjanarko2) 1) Fakultas Teknik, Univeritas Negeri Padang, Padang 2) Fakultas Teknologi Pertanian, Universitas Brawijaya, Malang Diterima 16 Januari 2014 / Disetujui 25 Juni 2014 ABSTRACT Noodle is one of the staple foods that are widely consumed and preferred by the Asian. However, wet noodles with modified cassava flour (mocaf) substitution resulted in lower quality compared to 100% wheat noodle. Addition of a certain amount of konjac glucomannan (Amorphophallus oncophyllus flour) to wet noodle is strongly recommended due to the fact that the food additive has a health benefit. Porang or konjac flour, which was used in the research, has soluble fiber properties, low calorie content, and highly viscous. It forms a heat stable gel with a mild alkali, interacts with starch, and has a synergistic interaction with kappa carrageenan. In this research, konjac flour was added to study the optimum combination between konjac and water. As much as 2, 4 and 6% (w/w) of konjac flour were combined with 35, 40, 45% (v/w) of water. The results showed that treatments with combinations of konjac flour and water were significantly contributing to characteristics of cooking time, cooking loss, color brightness index, tensile strength, swelling volume and water absorption. The best treatment was at a combination of 4% konjac (w/w) and 35% water (v/w). The best porang noodles have the characteristics of cooking time at 2.13 minutes, cooking loss of 35%, tensile strength of 0.14 N, water absorption of 201.58%, color brightness index of 51.41, swelling volume of 103.63%, moisture content of 31.77%, protein content of 5.87%, fat content of 2.13%, ash content of 0.85% and crude dietary fiber of 4.58%.

Spray drying technique is widely used to encapsule bioactive compounds. This study aims to determine the optimum encapsulant ratio and spray drying process to produce nanocapsule of liqud smoke. Nanocapsules production began with the mixing of encapsulant (chitosan and maltodextrin) and the liquid smoke and then agitated until dissolved. The solution of nanoparticles was heated in a water bath at 45°C for 5 minutes and homogenized using a homogenizer at 4000 rpm for 1 min. The nanoparticle solutions was spray dried at various temperatures and feed flow rates. Optimization is accomplished by using Response Surface Methodology (RSM), and the parameters to be optimized were chitosan concentration, inlet air temperature and feed flow rate of the spray dryer based on total phenolic content. Samples were analyzed for viscosity, pH, phenols staining, total phenolic, total carbonil, total acidity content, encapsulation efficiency, morphology profiles, and particle size distribution. The results showed that the nanoparticles solution of liquid smoke had a pH ranged between 2.55-2.64 total soluble solids ranged between 14-14.8°Brix and viscosity ranged between 8.7-14.9 centipoise (cP). The total phenolic content of the nanocapsules ranged from 1.38 to 2.32% with an efficiency ranged from 22.25 to 37.44%, and water content ranged from 9.56 to 10.73% (dry basis). The optimum conditions for the highest value of total phenolic content were 0.12% chitosan concentration, 140.65°C inlet air temperature and feed flow rate at 5.29 mL/min. The results suggested that nanocapsules had spherical and wrinkle shape with an average size of nanocapsules of 29.16 nm.

The Ghanaian cocoa liquor was used as the reference. The aroma of cocoa liquors was extracted by using a Solid Phase Microextraction (SPME), followed by detection with Gas Chromatography-Mass Spectrometry/Olfactometry (GC-MS/O) with the Nassal Impact Frequency (NIF) method. A total of 28 aroma active compounds in the cocoa liquors were identified, where in 21, 19, 22 and 18 compounds were detected in East Java, Bali, South Sulawesi and Ghana liquors, respectively. The profiles of these three liquors were not only different from one another but were also different from the reference. East Java liquor had a specific aroma of strong chocolate, enriched with creamy, caramel and coffee bean aroma, whileBali liquor was dominated by creamy, caramel and sweet, and South Sulawesi liquor was specified by its sweet green aroma. The aroma sensory characteristic was evaluated by descriptive test, presenting the aroma of nutty, acid, caramel, earthy and chocolate, while the taste sensory attributes included astringency, bitterness and acidity. The sensory profile analysis was carried out by applying a Quantitative Descriptive Analysis (QDA) method. Accompired with preference and ranking tests were also conducted. Among the three cocoa liquors, the sensory profile of South Sulawesi was the most similar to that of Ghanaian cocoa liquor. However, the cocoa liquor from Bali and East Java cocoa were more preferred comparing to the liquor from South Sulawesi.

Taman Kencana No. 1 Bogor 2) Departemen Biokimia, Fakultas Matematika dan Ilmu Pengetahuan Alam, Institut Pertanian Bogor, Bogor Diterima 24 Juni 2013 / Disetujui 10 Februari 2014 ABSTRACT Diacylglycerol (DAG) produced from crude palm oil (CPO) is one of the healthy oils that can be consumed for daily human diet. DAG production in Indonesia is constrained by the high cost of the mostly imported lipase. To overcome this problem, research of DAG production has been carried out using crude extracts of lipase produced by local species of fungi Rhizopus oryzae. This study aims to develop a continuous process of enzymatic glycerolysis of CPO for DAG production; to establish optimum conditions of DAG production which includes flow rate of CPO and glycerolysis time; and to test the performance of lipase from the local mold R. oryzae in catalyzing continuous process of glycerolysis for the production of DAG. Lipase isolation was carried out by acetone precipitation and lipase was used as a catalyst in the continuous glycerolysis process. The glycerolysis was conducted by reacting CPO with glycerol continuously at various time periods. The optimum condition of automatic continuous glycerolysis process was achieved at a CPO flow rate of 3 mL/min with a glycerolysis time at the 18 cycles (9 hours). The conversion of DAG was 29%. The performance of lipase was proven to remain stable up to 3 times changes of CPO substrate for 9 hours of glycerolysis process with the best condition at the 3 cycles and can improved conversion of DAG until 37%.
