Abstract

The research was conducted to compare antioxidant and antibacterial activities of some products derived from a typical fruit, locally known as Mahkota Dewa fruit (Phaleria macrocarpa (Scheff) Boerl). These products consist of: a dried fruit, an instant powder (produced by high temperature processing technique) and effervescent powder (produced by low temperature processing technique). The antioxidant activity was monitored within 8 days incubation, and the activity was determined after 24 hours of incubation against two respective bacteria, namely Staphylococcus aureus and Eschericia coli at various concentrations i.e.: 12.5%; 25% and 50%  respectively. The results showed that the three products contain high levels of antioxidant, but were less stable than that of the synthetic one. The highest antioxidant activity of all product was identified on the 4th day of incubation: 48,71% (an effervescent powder); 37,88% for the dried fruit and 33,27% for instant powder) the antioxidant activity of fruit and fruit product dropped significantly after 4 days of incubation. The products were more effective against E. coli than S. aureus and the activity increases with concentration.   Key Words: Mahkota Dewa, Antioksidant activity

Abstract

Whole cereal-based products, i.e maize and sorghum have a beneficial effect on health, but they also contain high level of phytate and tannin that defined as anti-nutrition which could affect protein digestibility.  The quality of protein can be improved by fermentation, as natural fermentation or with pure culture.  Dried culture containing lactic acid bacteria (Lactobacillus plantarum, Lactobacillus fermentum) and khamir (Saccharomyces cereviceae), is potential for cereal fermentation to decrease anti-nutrition compounds and to increase protein digestibility of cereal based product. The main objective of this research was to know the effect of applying dried mixed culture of L. plantarum, L. fermentum, and S. cereviceae on maize and sorghum flour fermentation, and to determine the effect of maize and sorghum flour fermentation on protein digestibility, antinutrition components, and other chemical and physical characteristics. The result showed that the mixed dried culture increased protein digestibility of fermented maize and sorghum flour, from 48.23% and 38.44% to 89.31% and 91.00%, respectively. Phytic acid content of maize flour decreased 43.14%, and tannin content of sorghum flour decreased 74.84%. Weaning food was made from fermented maize and sorghum flour had energy of 160 kcal for consumption of 40 g/day (for a 6 – 12 month child), and 312.5 kcal for consumption of 76 g/day (for a 13 – 24 month child).Keywords: dried mixed culture, maize fermentation, sorghum fermentation, antinutrition, protein digestibility

Abstract

Resistant starch, dietary fibres compound, is carbohydrate that escape from human digestion system, therefore it has potential health benefits. A study on resistance starch of the native and debranched starches, obtained from rice, which were further treated with physical or chemical treatment has been conducted. The extracted rice starch was first enzymatic debranched by means of bacterial pullulanase. The debranched starch was then treated further either by autoclaving, extrusion cooking or chemically cross-linking. The native starch was also undergone similar physical or chemical treatments.  The results showed that the treated debranched-starch contained a higher level of resistant starch than that of the native starch treated with the similar treatment. The cross linked debranched-starch was the best one and it contained 8.45% moisture, 3.19% ash, 85.44% starch and 3.67% resistant starch. The respective initial gelatinization temperature, gelatinization temperature and maximum viscosity of the modified starch were 79.3oC, 89.6oC and 1478 AU.Key word: resistant starch, enzymatic debranching, physical or chemical modification

Abstract

ABSTRAKBeras ketan (Oryza sativa var. glutinosa) yang umum dikenal dan dimanfaatkan masyarakat saat ini adalah beras ketan putih dan beras ketan hitam, sedangkan beras ketan merah sangat jarang diketahui oleh sebagian besar masyarakat. Masyarakat di daerah tertentu seperti di Pakis, kabupaten Pacitan telah lama mengenal, menanam, dan mengolah beras ketan merah menjadi snack seperti tape ketan merah, rengginang ketan merah, dan lain sebagainya. Diduga ketan merah sama seperti beras berpigmen lainnya mengandung asam fenolat dan senyawa bioaktif lainnya serta memiliki aktivitas antioksidan. Penelitian ini bertujuan untuk identifikasi kandungan asam fenolatat pada ketan pecah kulit, ketan sosoh dan bekatulnya. Setiap sampel diekstrak kandungan fenolat bebas, fenolat terikat dan fenolat terkonjugasi kemudian hasil ekstraksi dianalisis total fenolat metode folin-ciocalteau serta aktivitas antioksidan metode DPPH. Penelitian ini bersifat deskriptif kuantitatif, dengan tiga kali ulangan. Pada semua sampel, baik pada ketan pecah kulit, ketan sosoh (bagian endosperm) maupun bekatul (bran) mengandung lebih banyak total fenolat terikat dan terkonjugasi (bebas-terikat) daripada fenolat bebas. Aktivitas antioksidan ekstrak senyawa fenolat tertinggi terdapat pada ketan merah pecah kulit meliputi semua jenis fenolat yaitu ekstrak fenolat bebas IC50 4.52 mg/ml, fenolat terkonjugasi 3 IC50 9.92 mg/ml dan fenolat terikat IC50 30.65 mg/ml ABSTRACTThe most common Glutinous rice (Oryza sativa var. glutinosa) is white glutinous rice and black glutinous rice, but red glutinous rice rather infrequently. However, only few people have known about red glutinous rice, local glutinous cultivars in Pakis, Pacitan, East Java. People in there are used to cultivating red glutinous rice for long time ago and processing into various kinds of snack, such as tape, rengginang. Like the other pigmented rice, red glutinous rice contained phenolic and other bioactive compounds which contained antioxidant activity.
