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.

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.

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.

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.

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).

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.

Snake fruits kernel has high cellulose content thus potential to be an alternative source of carboxylmethylcellulose (CMC) production. However there are several condition that have to be optimized to increase the CMC synthesis which are concentration of NaOH solution, NaMCA addition, and the reaction temperature based on the degree of substitution (DS). The aim of this study was to determine the optimum conditions of synthesis CMC from “Salak Pondoh Super” kernel. Some factors that likely influence the synthesis were concentration of NaOH solution , NaMCA addition, and the reaction temperature based on the degree of substitution (DS) as the responses. Synthesis of CMC was optimized using completely randomized design. The result then was characterized by several parameters including water content, viscosity, purity, Water Holding Capacity (WHC), Oil Holding Capacity (OHC), lightness, crystallinity, and FT-IR spectra. Optimization was achieved by the use of 15% NaOH solution, 5 gram NaMCA per 5 gram cellulose and reaction temperature of 55oC. The characteristics of the optimized CMC were DS 0.825, purity 90.86%, water content of 7.16 (% wb), viscosity 3.86 cps, 142.72 yield (% db), WHC 2.37 (g/g), OHC 2.31 (g/g), lightness 78.48, and crystanillity 32.69%. The FT-IR spectra of snake fruit kernel CMC was similar with the CMC Standard.

Most of Indonesia’s cocoa beans has been produced through fermentation. Various metabolite end products such as alcohol, lactic acid, and acetic acid are produced during cocoa beans fermentation. These metabolites would induce different chemical characteristic of fermented cocoa beans. In this research, parameters evaluated were OTA and AFs contamination to determine the susceptibility of fermented and unfermented cocoa beans on OTA and AFs production during storage simulation. To investigate the susceptibility, this research was conducted on storage simulation condition which was 91% of relative humidity. It is hypothesized that metabolic end-products from the breakdown substrate during fermentation process have an effect on mycotoxin production by fungi. This is the first report of ochratoxin A and aflatoxins contamination susceptibility in fermented and unfermented cocoa beans. Fermented cocoa beans were more susceptible to AFs contamination. The highest AFs contamination was found in fermented inoculated cocoa beans after 10 days storage. Unfermented cocoa beans were more susceptible to OTA production. The highest OTA contamination was found in unfermented inoculated cocoa beans after 15 days storage. The results of the present study indicated a promising different potential between ochratoxin A and aflatoxins production in fermented and unfermented cocoa beans during simulation storage condition, suggesting the existence of limiting factors on the accumulation of ochratoxin A and aflatoxins in the beans by the metabolic-end products produced during fermentation.

Jack bean is one of local beans known to contain natural resistant starch (RS) content. To increase its RS content, four cycle autoclaving – cooling treatment modification was applied to generate resistant starch type 4 (RS-4) which refers to RS obtained from modification. RS is able to improve blood glucose level of diabetic individuals. This research aimed to measure the effect of jack bean autoclaved – cooled starch (AC starch) diet on blood glucose level and digesta characteristics of type-2 diabetic Sprague Dawley rats in vivo. Bioassay analyses showed that jack bean AC starch consumption decreased blood glucose level at range of 96.05mg/dl – 135.97mg/dl. The diet was also able to increase short chain fatty acids (SCFA) production in form of acetic acid, propionic acid, and butiric acid, to increase total weight and moisture content of digesta, while reduce digesta pH, as well as to inhibit glucose absorption. Diet of 50% high RS jack bean AC starch showed the best results in all glucose metabolism parameters for type-2 diabetic animals.

To increase its RS content, four cycle autoclaving – cooling treatment modification was applied to generate resistant starch type 4 (RS-4) which refers to RS obtained from modification. RS is able to improve blood glucose level of diabetic individuals. This research aimed to measure the effect of jack bean autoclaved – cooled starch (AC starch) diet on blood glucose level and digesta characteristics of type-2 diabetic Sprague Dawley rats in vivo. Bioassay analyses showed that jack bean AC starch consumption decreased blood glucose level at range of 96.05mg/dl – 135.97mg/dl.
