Hibiscus sabdariffa commonly named as “red sorrel” or “roselle” is a member of malvaceae family. It is a medicinal plant with a worldwide fame and has more than three hundred species which are distributed in tropical and subtropical regions around the world. Roselle can adapt to a variety of soil in a warmer and more humid climate. Roselle is rich in organic acids including citric, malic, tarta...

Physicochemical, nutritional and functional properties of protein fractions and protein isolate (RSPI) from Roselle seed were investigated. The protein content was 91.50, 93.77, 81.55, 71.30 and 40.83% for RSPI, globulin, albumin, glutelin and prolamin, respectively. The functional properties were variable among samples. Glutelin possessed the highest water holding capacity and albumin the lowe...

A study was conducted using LabPlant SD-06 Spray Dryer to produce spray-dried rosellepineapple powder. Roselle calyces and pineapples were extracted under optimum condition. Three different maltodextrin DE 10 concentrations (3%, 5% and 10%) were added (w/w) as the encapsulating agent prior to spray drying. Inlet temperatures were varied at 140 C, 160 C and 180 C respectively and the outlet temp...

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...

Roselle (Hibiscus sabdariffa) calyx was fermented traditionally and by controlled method with pure strains of Aspergillus flavus and Saccharomyces cerevisiae isolated from the fermentation. The proximate composition revealed that the sample fermented traditionally had the highest protein content of 14.7±2.5%. There was a significant decrease (Pd≤0.05) in the antinutrient content (phytate and ta...

Background and Objectives: Roselle (Hibiscus sabdariffa L.) is one of the valuable plants grown in tropical and subtropical regions such as some parts of Iran. Roselle calyces are commonly used to make  herbal tea as well as a natural food color additive. However, Roselle seeds are usually discarded as by–products, while they can be used as a source of nutritious and functional compo...

The aim of this study is to compare the metallic and natural fiber reinforced polymer composite bone plates used in humerus fractures. A 3D finite element model was developed to analyze the performance of both types of plates. This study proposed on fabrication of natural fiber powdered material (like Sisal (Agave sisalana), Banana (Musa sapientum) and Roselle (Hibiscus sabdariffa)) Reinforced ...
