Indonesia is an agricultural country where the livelihoods of the majority of the population to grow crops. Geographically Indonesia is an archipelago which also has great natural potential not only in the field of marine but also in agricultural processing. One of the results is a leading Indonesian agriculture is rice. It is not apart from the fact that rice as a staple food of Indonesia. In this study, researchers will describe the manufacturing process and the final result in the making of bread made from bran flour. Where researchers will create four kinds of bread, which is bread without flour bran as quality control (P0), white bread with a mixture of 10% flour bran (P1), white bread with a mixture of 20% flour bran (P2), and bread with 30% bran flour mixture (P3). Objects were observed in this study was to determine the final result of the manufacture of bread to test the texture, color, flavor, and aroma with a mixture of flour bran, the method of making the same, cooking equipment are the same, long fermentation time the same, the temperature of the oven the same and roasting the same time.

Biji nangka kurang diminati oleh masyarakat sebagai bahan pangan. Biji nangka memiliki kandungan senyawa flavonoid yang dapat digunakan sebagai pengobatan. Tujuan peneliti adalah untuk mengetahui pengaruh lama fermentasi terhadap kadar flavonoid total pada ekstrak tape biji nangka (Artocarpus heterophylla Lamk.) yang dilakukan dengan alat spektrofotometer UV-Vis. Manfaat dari penelitian untuk menambah wawasan di bidang farmasi khususnya tentang ilmu kimia amami mengenai pengaruh lama fermentasi terhadap kadar flavonoid total pada ekstrak tape biji nangka (Artocarpus heterophylla Lamk.). Metode ekstraksi yang digunakan adalah metode maserasi dengan mengunakan pelarut etanol 96%. Identifikasi kualitatif mengunakan uji Shinoda, uji NaOH 10%, uji H2SO4 (pekat). Hasil uji kualitatif menunjukan sampel positif mengandung flavonoid. Kesimpulan pada hasil penelitian penetapan kadar flavonoid total yang terkandung dalam ekstrak tape biji nangka pada hari ke-0 sebesar 2,9146±0,0245 mgQE/gram ekstrak, pada hari ke-1 sebesar 3,3050±0,0240 mgQE/gram ekstrak, pada hari ke-2 sebesar 3,6829±0,0244 mgQE/gram ekstrak, dan pada hari ke-3 sebesar 4,0488±0,0244 mgQE/gram ekstrak.  Jackfruit seeds are less interest by the community (people) as food.  Jackfruit seeds containing flavonoid compounds where it can be used as a treatment.  The aim of the researchers was to determine the effect of fermentation time on total flavonoid concentration  in jackfruit fermented seed extracts with a UV-Vis spectrophotometer. The benefits of research to add insight in the field of pharmacy especially about chemistry of amami regarding effect of fermentation time on total flavonoid levels in jackfruit seed “tape” extract (Artocarpus heterophylla Lamk.). Extraction method used is the maceration method using 96% ethanol solvent. Qualitative identification using the Shinoda test, 10% NaOH test, and H2SO4 (concentrated) test. Qualitative test results showed a positive sample containing flavonoids. Conclusions on the results of the experiment  are jackfruit seed "tape" extract on day-0 was 2.9146±0.0245  mgQE/gram extract, on day-1 was 3.3050±0.0240 mgQE/gram extract, on day-2 was 3.68293±0.0244 mgQE/gram and on day-3 was 4.0488±0.024 mgQE /gram extract. The longer fermentation, total flavonoid concentration interest.

Abstract Background Lactic acid bacteria can synthesize dextran and oligosaccharides with different functionality, depending on the strain and fermentation conditions. As natural structure-forming agent, dextran has proven useful as food additive, improving the properties of several raw materials with poor technological quality, such as cereal by-products, fiber-and protein-rich matrices, enabling their use in food applications. In this study, we assessed dextran biosynthesis in situ during fermentation of brewers´ spent grain (BSG), the main by-product of beer brewing industry, with Leuconostoc pseudomesenteroides DSM20193 and Weissella confusa A16. The starters performance and the primary metabolites formed during 24 h of fermentation with and without 4% sucrose (w/w) were followed. Results The starters showed similar growth and acidification kinetics, but different sugar utilization, especially in presence of sucrose. Viscosity increase in fermented BSG containing sucrose occurred first after 10 h, and it kept increasing until 24 h concomitantly with dextran formation. Dextran content after 24 h was approximately 1% on the total weight of the BSG. Oligosaccharides with different degree of polymerization were formed together with dextran from 10 to 24 h. Three dextransucrase genes were identified in L. pseudomesenteroides DSM20193, one of which was significantly upregulated and remained active throughout the fermentation time. One dextransucrase gene was identified in W. confusa A16 also showing a typical induction profile, with highest upregulation at 10 h. Conclusions Selected lactic acid bacteria starters produced significant amount of dextran in brewers’ spent grain while forming oligosaccharides with different degree of polymerization. Putative dextransucrase genes identified in the starters showed a typical induction profile. Formation of dextran and oligosaccharides in BSG during lactic acid bacteria fermentation can be tailored to achieve specific technological properties of this raw material, contributing to its reintegration into the food chain.
