This study aimed to determine the exact cinnamon concentration in manufacture of rosella flower petal syrup based on its physical and chemical properties. A completely randomized experimental design with six levels concentration, i.e., 0, 1, 3, 5, 7, 9 g, respectively, replicated four times was applied this research. Analyses were performed both concentrated diluted forms syrup. Parameters obse...

A solar cell was manufactured from local materials and dyed using dyes extracted different organic plants. The glass slides were coated with a nano-porous layer of Titanium Oxide infused two types acids, Nitric acid Acetic acid. Pomegranate, Hibiscus, Blackberry Blue Flowers. They then tested comparison made for the amount voltage they generate when exposed to sunlight. Hibiscus sabdariffa extr...

To date, there are very few data regarding new efficient probiotics’ development with their own prebiotic substrate. All commercial products contain substrate that was previously purified from external sources and added to the final product. The present study describes Weissella confusa strain fermentations in media different anthocyanin concentrations Hibiscus sabdariffa L., order increase exo...

Milled Roselle (Hibiscus sabdariffa L.) seeds of the UMKL cultivar were analyzed for proximate composition, water and oil absorption capacity, and the influence of storage conditions on storage stability. The storage stability was determined under four types of conditions: light/oxygen (air) (LO), light/nitrogen (LN), darkness/oxygen (air) (DO), and darkness/nitrogen (DN) while monitoring for s...
