Spices, in the form of oleoresin, have advantages as a flavoring agent. Nutmeg oleoresin compounds that play an important role in the formation of nutmeg flavor are myristicin, elemicin, and safrole. These compounds are not stable, so that the quality of oleoresin decreased easily. An alternative to overcome this problem is the encapsulation of oleoresin using spray drying techniques. The objective of this research was to evaluate the physicochemical properties of oleoresin with respect to the degradation of myristicin, elemicin, and safrole of nutmeg oleoresin. Microencapsulated nutmeg oleoresin was prepared using 12% WPC and 88% maltodextrin as encapsulate materials. It was stored in dark glass bottles at a various temperature, namely 30°C, 40°C, 50°C, 60°C, and 70°C, for 0, 4, 7, 10, 14, 21, 28, 35, 42, 49, 56 and 63 days. The content of myristicin, elemicin, and safrole were analysed. The results showed that myristicin, elemicin, and safrole in the encapsulated nutmeg oleoresin decreased during the storage until 28 days of storage and then they were relatively stable until 63 days. The activation energy of myristicin, elemicin, and safrole were 2.21 kJ/mol.K, 2.71 kJ/mol.K and 3.22 kJ/mol.K, respectively.

Angkak (red fungi rice, red yeast rice) is a traditional fermentation by fungi Monascus in a lot of Asia Countries, which is useful as a natural food colorant. The aim of this research was to obtain pure isolate of red fungus from angkak in Semarang. The growth and the red pigment production of the selected isolate in the different initial medium pH and nitrogen sources were observed. The treatment was done by growing the isolate in PDB (Potato Dextrose Broth) medium at initial pH 3, 5, 7 and 9 and as well as optimization of nitrogen sources with 1% ammonium chloride, 1% ammonium nitrate, and 1% peptone. Analysis of the fungi growth was performed by weighing mycelia biomass using dry weight method and the red pigments were analysis using spectrophotometer at a wavelength (λ max ) of 500 nm. The results showed that the highest absorbance value of pigment (0.81) was obtained at pH 7, and the highest value of the cell dry weight was also obtained at pH 7 (1.23 g/L). The results showed that 1% ammonium chloride was the best nitrogen source for absorbance of red pigment production (0.82), but the highest of dry weight (2.56 g/L) was obtained by using medium with 1% ammonium nitrate as a nitrogen source.

Kempong is a traditional fermented food that is found only in South Karangpucung Linggapura Bumiayu village, Central Java. It is prepared from palm kernel cake (PKC). This fermented food is consumed mostly everyday by the people in the village as a side dish or snack. Study on the mold important in the kempong fermentation was done by isolating molds from kempong, PKC, laru and the air of preparation room. Eleven species of molds were successfully isolated from different samples. Among the mold isolates three species came out from kempong product, i.e. R. oryzae, E. chevaliery and A. oryzae . The isolates showed the capability in producing amylase, protease, lipase, and cellulase. Both R. oryzae and A. oryzae indicated as the main fermentation mold in kempong production, because the inoculum laru only contained these two species.

Biopreservation is one of the alternatives to obtain safe food products. The produced bacteriocin by Lactic Acid Bacteria (LAB) is potential as biopreservatives, which is safe for consumption, since it was a protein degradable by proteolytic enzymes. This study aimed to optimize bacteriocin production from L. plantarum IBL-2 and to evaluate the effectiveness of bacteriocins in reducing the number of total plate count and Salmonella typhimurium in ground beef. Bacteriocin was produced through fermentation of L. plantarum IBL-2 , under various conditions to yield the compound with the best antimicrobial activity. The total number of bacteria in ground beef after the addition of L. plantarum IBL-2 fermentation supernatant was determined. The result was compared with the sample without preservatives (control), and sample added with commercial Nissin. All three samples of ground beef were spiked with S. typhimurium and incubated for 0, 2, 6, 8, 12, 14 days at a temperature of 4-10 ° C. Total Plate Count (TPC) method was utilized to determine the number of bacteria in the samples. The fermentation process resulted in bacteriocin with the strongest antimicrobial activity when using low molecular weight liquid medium (LMWLM), followed by a series of refining process. From day 0-14, the number of S. typhimurium, in sample added with L. plantarum IBL-2 fermentation supernatant, was lower than control and sample added with Nissin. The most optimal antimicrobial activity of bacteriocin was obtained using LMWLM as fermentation media, and using a series of refining process consist of bacteriocin supernatant evaporation, membrane ultrafiltration, and gradual fractionation using 80% ammonium sulphate. Bacteriocin from L. plantarum IBL-2 showed antimicrobial activity against S. typhimurium.

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

The aim of this research was to study the binding ability of viable and non-viable of Lactobacillus paracasei SNP-2 to aflatoxin B 1 (AFB 1 ) in phosphate buffer saline (PBS) at pH 7.3. Bacterial cells were grown in MRS broth at 37 °C for 24 h, and then centrifuged at 1,800 g[a1] for 20 min at 10 °C to get the pellet. Pellet was suspended in PBS pH 7.3 until the cell concentration was about 10 10 CFU/ml. Viable cells, the heated, and acid-killed cells were evaluated their ability to bind AFB 1 in PBS pH 7.3. Stability of the L. paracasei SNP-2/AFB 1 complexes was evaluated by determining the amount of the released AFB 1 to the PBS following five times washing. The results showed that AFB 1 binding ability to heat-and acid-kill bacteria were higher than that of by viable cells. More than 70% of bound AFB 1 was released from viable bacteria after five times washing. However, the heated and acid-killed cell treatments significantly increased the complex stability of bacteria-AFB 1
