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

Abstract

Milkfish that have been seasoned with some spices then cooked by a high -cooker produced a fish product which has soft spines and bones. The product which has a local name bandeng presto has been popular in Indonesia due to the product is tasty and it is easier to be consumed directly after it is prepared as a dish. The storage life of bandeng presto is relatively short, which is due to deterioration process by microbes after processing. Consequently, this condition can retard the products distribution. The aims of the research are to understand is there any significant influence of differing the drying time (0 hours and 4 hours) of milkfish cooked by a high-pressure cooker by using an electric oven (50oC) and storage period at room temperature (5 days) and also to find out which treatment produce the best product quality. The results showed that the treatment of differing the drying period gave a highly significant influence (P <0.01) on the sensory value and the moisture content but did not gave significant influence (P >0.05) on the number of bacteria colonies. The length of storage period gave a highly significant influence (P <0.01) on the sensory value between the products which were dried for 4 hours and without drying treatment but only the drying process for 4 hours gave a highly significant influence (P <0.01) on the moisture content, the water activity and the number of bacteria colonies. The quality of the products that were dried for 4 hours were better and their storage life can reach up to 3 days compared to the products that were not dried.Keywords: Milkfish, high pressure cooker, drying, oven, quality, storage life

Abstract

Amylose content related to the glycemic index, the higher the content of amylose the lower the glycemic index thus good for diets. Starch modification through fermentation using lactic acid bacteria can be used to increase amylose. In this experiment, modification of Square banana (Musa balbisiana) flour was conducted using Lactobacillus fermentum at certain concentration and fermentation time. This study used a Completely Randomized Factorial Designs (CRFD) with variation of fermentation time (24 hours, 48 hours, 72 hours) and concentration of bacteria starter (0.125%; 0.250%; 0.375% v/v) as the factor. Data were statistically analyzed using Two-Way ANOVA. The results showed that the variation of fermentation time and concentration of starter change physical, chemical, and sensory characteristic of the flour. Water absorption, protein content, and amylose content were increased. However whiteness index, swelling power, solubility, and moisture content were decreased. Pasting properties was change significantly after this modification process. Meanwhile, antioxidant activity and sensory characteristics did not significantly change. In conclusion, the characteristics of the modified flour offer opportunities for the development of square banana flour-based food products with high amylose which good for the diet.

Abstract

Rice is considered as staple food that consumed in the form of steamed rice. Due to the emergency condition, like volcano eruption or flood, the availability and accessibility might be a serious problem. Therefore, a ready-to-eat rice is necessary. It would need a design processing condition to produce practical cooked rice in more economically packaging with different method.Normal packaging and vacuum packaging of cooked rice  followed by steaming for 60 minutes was conducted in this study. Two different storage temperatures include cold and room storage in day 0, 1, 4, and 7 was used to evaluate. The result showed that vacuum packaging gave better reduction in microbial parameter. However, panelist gave same preference in both normal and vacuum packaged cooked rice. Overall, cold stored-packaged cooked rice gave better quality than room stored-packaged cooked rice, especially in microbial parameter. Thus, combination of vacuum packaging and cold storing could be an alternative way to produce cooked rice which can be consumed in difficult condition.

Abstract

Lactic acid bacteria have been isolated from several Indonesian indigenous fermented foods and screened for the potential strains as probiotic candidates. The aim of this study was to evaluate sensory properties and respondents’ preference of yogurt-like set and yogurt-like drink with various Indonesian indigenous probiotic strains produced by dairy industry. Indigenous probiotics of Lactobacillus plantarum MUT-7 and Lactobacillus plantarum DAD-13 were used to produce yogurt-like set and yogurt-like drink. Family perception toward yogurt-like drink was performed in Yogyakarta involving 100 family members. The yogurt-like products were also compared to yogurt containing commercial Lactobacilus bulgaricus and Streptococus thermophilus or commercial yogurt produced by dairy company. Several sensory evaluation toward sensory properties and panelist’s preference were performed in different cities.  The result showed that the indigenous probiotic L. plantarum DAD-13 and L. plantarum MUT-7 were potential to be used as a starter culture for the production of yogurt-like set and yogurt-like drink. The combination of indigenous probiotics and indigenous lactic acid bacteria S. thermophilus DAD-11 resulted in better sensory properties of yogurt set compared to combination of L. bulgaricus and S. thermophilus.

Abstract

Probiotics are living microorganism which give health benefit when consumed. Probiotic needs a ‘vehicle’ for their specialized actions in gastrointestinal tract. In this research, tape ketan was used as ‘vehicle’. The objective of this research was to produce probiotic tape ketan powder as an ingredient of functional beverage. Tape ketan used in this research was made by fermentation of glutinous rice with ragi and supplemented with Lactobacillus plantarum Dad 13 (107CFU/g glutinous rice). Probiotic powder was obtained using spray dryer with inlet temperature of 90oC with the addition of 35% maltodextrin. The powder was reconstituted into water with addition of pectin and sucrose. The results showed that viability of lactic acid bacteria and L. plantarum decreased after drying (0.82 and 0.90 log cycle respectively) with viable count from 1.29x1010 CFU to 1.96x109 CFU for lactic acid bacteria and from 1.04x1010 CFU to 1.32x109 CFU for L. plantarum. To obtain probiotic tape ketan beverage, 20% tape ketan powder (w/v), 0.5% pectin (w/v) and 4% sucrose (w/v) were reconstituted. Tape ketan powder which was supplemented with probiotic Lactobacillus plantarum Dad 13 is potential as an ingredient of functional beverage (from the viability after drying).

Abstract

The clean river is very important for human life and river’s biota. However, many rivers are polluted from both domestic and industrial waste today. Domestic waste comes from households and industrial wastes from nearby industrial activities. One of the biotas of the river is the fish. The objective of the research was to evaluate pollutant and pollutant index in the watershed and the present of Pb in fish in the watershed. The location of this research was a long Garang watershed Semarang, namely from upstream to downstream of the river. The sampling area was divided into 7 segments based on Central Java Governor Regulation No. 156/2010 based on water designation. The studied parameters in this research were heavy metal in fish and water quality. The studied fish was Nila fish (Oreochromis sp.). Results show that Cu was the main pollutant in water river class 1, 2, 3 and 4. DO exceed the limit parameter in water river class 3 and 4. Finally, the highest heavy metals found in fish were found in Pb, while the water pollution index was due to exceeding Cu, all of which came from industrial waste.

Abstract

Black rice has higher anthocyanin content and other nutritional values than white rice but is not preferable as staple food by Indonesian people especially for its aroma and texture. Mixing black rice with white rice was expected to increased its cooking and eating qualities but might be affected its commercial and nutritional qualities. Local cultivars of black rice Cempo Ireng and white rice Mentik Wangi were mixed at ratios 1:0 (S1), 3:1 (S2), 1:1 (S3), 1:3 (S4) and 0:1 (S5) w/w. The raw and cooked mixed rice were physically, chemically, physicochemically and sensorily analyzed to determined its commercial, cooking, eating and nutritional qualities. The addition of white rice increased the cooking and eating qualities of mixed rice but reduce its nutritional value. It had been suggested that the ratio of black rice and white rice must not lower than 1:1 to preserve its eating and nutritional qualities.
