Abstract

Agricultural products are expected to survive as export commodities under severe economic crises. Such an expectation could not be fully achieved due to the fact that some Indonesian food commodities exported to USA were held under detention by FDA. The detained food products were mostly cocoa bean, canned tuna, frozen shrimp and fish. Cocoa bean detention was due to the presence of filth and foreign objects, while for frozen shrimp and fish were due to the presence of filth, inadequate sanitary handling, and Salmonella contamination. Detention of canned tuna shipments were due to the presence of filth, decomposition, no accompanying canning schedule process document, or no compliance with the labeling requirements. Especially for cocoa bean export to USA up to present Indonesia has been subjected to automatic detention. Quality management and food safety, against the potential Indonesian export commodities should he improved to he able to compete in global market.

Abstract

Physical quality of fruits is commonly determined by their texture. The texture of fruits often depends on its maturity level. Generally the texture of fruits is quantified by their firmness that is defined as the force to attain certain deformation. However fruits can not be considered as simple elastic materials. They are more appropriately considered as non linear viscoelastic objects with three parameters. Accordingly the objectives of the study were to determine the viscoelastic parameters of fruits by impact and to relate those parameters to the sensory evaluations of the maturity of the samples. Samples were sapota fruits stored and ripened at mom temperature. The samples Were impacted onto hard surface and the impact forces were recorded using a computer. The impact forces were analyzed to determine the viscoelastic parameters. The maturity indices of the samples were determined by sensory evaluation and then compared to the impact parameters. The results indicated that the impact parameters can be related to the maturity index. It seems that the maturity of fruits can be determined by impact.

Abstract

Peroxidation of membrane lipid is implicated with several health disorders and antioxidants are perceived capable of controlling the reaction. Quest for new natural antioxidant dominating research topics in the last decade. Test and validation of their usefulness becoming more important, especially in vivo on human subject. Current method for peroxidation tests, such as loss of polyunsaturated fatty acids, conjugated dienes, singlet oxygen, lipid hydroperoxides and malonaldehyde provide reliable data, however, the methods are lengthy and requiring blood or urine samples. New non-invasive and quicker methods are required. Gas exhale by individual, that considered to be secondary product of lipid peroxidation are among markers candidates. Among the exhaled gases, ethylene, methane, ethane and pentane fall into the category. Ethylene and methane, however, are not specifically product of lipid oxidation. Ethylene is also produced during protein and carbohydrate oxidation, while methane is produced in a large amount by colon bacteria. Ethane and pentane are proved to be most good peroxidation marker and results are in a good correlation with the current methods. However, the two gases are produced in a very low concentration just slightlyabove that in ambient air. The detection of the twt gases utilizing gas chromatography requiring specia technique for air cleaning and concentration due to laci ofsensitivity. The laser driven photoacoustic spectrom eter is capable of detecting the two gases with more than 1000 times in sensitivity. Its uses in the detection of the two lipid peroxidation markers would be a po, tential for future peroxidation or antioxidant challenge test.

Abstract

The residence time distribution of fluid passing through a tubular reactor was studied to predict the performance of a tubular enzyme reactor. It was found that there was a great amount of dispersion from the ideal plug-flow over the range of flow rate of 15 ml/min to 78 ml/min. Sucrose hydrolysis by yeast invertase has been selected as an enzymatic model reaction in a tubular reactor. The kinetics of invertase were studied by the observation of the initial rates of reaction at various substrate concentrations.            A mathematical model which described the degree of conversion of a tubular enzyme reactor as a function of flow rate is developed. The expression of the rate of reaction is approximated by a linear function using Maclaurin theorem. The dispersion model shows good agreement with the observations on sucrose hidrolyzed by invertase in a tubular reactor.

Abstract

Production of antibacteria of Lactobacillus plantarum TGR-2 was carried out by mutation technique using UV radiation and chemical mutagenic agent (acrydine orange (AO), ethyl methane sulfonate (EMS), and N-methyl-N-nitro sulfonate nitrosoguanidine (NTG). As a marker was applied chloramphenicol for 10 ppm. Total 214 mutants were obtained from all of the treatments and then screened based on their activities against Staphylococcus aureus FNCC 0047 as bacterial indicator, using agar diffusion and turbidimetric assay techniques. Results showed that 24 mutants could produce higher amount of antibacteria and two of them, NTG and acrydine orange treatments, had higher stability than others. Characterization of two mutants, determination of biochemistry traits and optimization of antibacterial (bacteriocin) production were done. The product showed that UV-15, EMS-10, AO-6 and NTG-21 mutants could produce antibacterial substance 3,90, 4.40, 3.40 and 4.17 AU/ml for 16, 12, 12, and 16 hours incubation, respectively, compared to Lactobacillus plantarum TGR-2 which produced 1.07 UA/ ml for 24 hours incubation.

Abstract

            Aquatic organisms exposed to low lovel natural heavy metals pollutant tend to accumulate in their tissue by means of metabolic and biosorption processes. However, the influence of external environment to heavy metal bioavailability and internal organism characteristics to bioaccumulation processes remain uncertain. In this work, the influence of Cu, Zn, Cd and Hg bioavailability, feeding strategies and heavy metals homeostasis regulations or detoxification mechanisms to bioaccumulation pattern in aquatic bioindicators were studied.            Only Hg in Segara Anakan water samples was determined, while Cu, Zn and Cd were not detected. Sediment samples of Segara Anakan indicated higher heavy metals level than those of Serang river mouth, but only Hg concentration in sediment samples of Segara Anakan which is significantly higher than those of Serang river mouth, while Cd was not detected. The trend of heavy metals bioconcentration ratio of filter feeder Geloina spp and planktonic grazer Penaeus marguensis follows the desorption coefficient, i.e. Zn>Hg>Cu, but the bioconcentration trend in Scilla serrata, which is macrobenthos predator, is Hg>Zn>Cu.            The exposed Cu was not accumulated by Geloina spp., but accumulated at highest concentration in the exoskeleton of Penaeus marguensis and cartilage of Scilla serrata. Highest accumulation concentration of Zn and Hg were determined in meat, and lower concentrations were determined at other tissues. The extent of heavy metals bioaccumulation in Geloina spp. and Scilla serrata reflect the pollution of the surrounding environment, but the extent of heavy metal bioaccumulation in Penaeus marguensis were influenced more by its physiological status. Since the environmental exposure of Hg in Segara Anakan estuary was relatively high, pregnant women from this region should consider the potential hazard of Hg to their fetus when consuming aquatic organism of higher trophic level such as estuarine crabs.

Abstract

The objective of the research was to determine the effect of the germination of black rice. Black rice was soaked for 12 h and further germinated for 12, 24, 36, and 48 h. Non-germinated black rice was used as a control. Black rice was germinated for 19-20 h. Fat, and moisture content, total sugar, cooking quality, sensory analysis, and fatty acid composition of germinated black rice were further evaluated. Results show that fat content decreased during germination, but moisture content and total sugar increased. Physiochemical properties, such as length expansion ratio, volumetric expansion, water absorption, gel consistency, and alkali values were in the ranges of 0.77-0.91 mm, 2.42-3.38, 1.64-2.04, 66-82.5 mm, and 2-3.5, respectively. From sensory analysis, most of panelists were favorable for the germinated black rice at 24 h germination. SFA and MUFA tended to decrease during germination but PUFA tended to increase. Thus the germination is effective to improve nutritional values of black rice

Abstract

Tofu is a high protein food which is widely consumed in Indonesia. In this study, we used the variety of coagulant which is CaSO4 and papain enzymes. The extraction of soybean protein was conducted using selected ratio (1:2), then coagulated using two different coagulant which are CaSO4 (1 and 2 gram) and papain enzyme (3 and 6 gram). The highest yield of tofu used CaSO4 2 gram with 66% yield and papain enzyme 6 gram with 65% yield. This indicates that more of coagulant are used so more yield of tofu. Based on the proximate test, especially proteins showed the making of tofu with papain enzyme (9.29%) gave higher protein content than CaSO4 (6.50%) as coagulant.Keywords: Tofu, soybean, CaSO4, papain enzyme

Abstract

The aims of this research were to know the effect of combine iles-iles (refined starch, whole iles-iles flour, and refined glucomannan) as encapsulating agent (capsule materials) and different protectant agents to get microcapsule synbiotic, which have the highest number of probiotic cells and high viability against low pH and bile salt. Design blocks complete with factorial design was used in the experimental design. The first factor was capsule materials with a concentration of 10% consisting of three material types: A1 (refined glucomannan), A2 (refined starch), and A3 (Iles-iles native). The second factor was protectant, protecting the probiotic bacteria during spray drying, used at concentration of 5% consisting of three substances i.e. B1 (skim milk), B2 (maltodextrin), and B3 (gum arabic). Using protectant agents on the MRS for the growth of L. casei resulted no effects against the numbers of LAB (lactic acid bacteria), density, moisture content, and hygroscopicity; however, it had influence on yield and solubility. The best use based on the reduction of LAB numbers were flour and gum Arabic which was significant compared to other fractions.Keywords: iles-iles, glucomannan, starch, protectant agent, symbiotic LAB

Abstract

Salmonella sp. is an enteropathogenic organism and it can spread through contaminated food which is rich in nutrition such as raw milk. The goal from this research is to find out the suitable pasteurization and time effect on the growth isolates Salmonella sp. that its invA presence is detected. Seventy-five (75) samples were taken in three locations of milk collection from groups of breeders. 10 ml of milk samples were grown in enrichment culture of modified Tryptic Soy Broth (mTSB) at 37oC for 12 hours. Cellular culture was then grown in differential selective medium of Salmonella Shigella Agar (SSA) and Chromocult Coliform Agar (CCA). From 75 milk samples produced 1392 colonies of typical Salmonella sp. pathogens. Then, isolates were selected using Triple Sugar Iron Agar (TSIA) and Urea Broth media, producing 3 suspected isolates of Salmonella sp which was known from colonies color. Results of confirmation using API 20E and 50 CHE produced two isolates of Salmonella spp. with %ID = 99.6% and one isolate of Salmonella typhi with %ID = 72.1%. All of the isolates were then detected for virulence factor using invA marker and all positive isolates have virulence factor. It indicates that raw milk contains polluted pathogenic bacteria.Keywords: raw milk, enteric pathogenic, virulence gen
