Research ArticleOpen accessIn the keywordsOptimization of Egg Tofu Formulations Containing Carrageenan, Gum Arabic and Corn Starch by Descriptive Sensory AnalysisMaizura Murad, Aminah Abdullah, Wan Aida Wan MustaphaThe objectives of this study was to determine the effects of carrageenan, gum Arabic and corn starch on the sensory characteristics of egg tofu and to optimize egg tofu formulations using Response Surface Methodology (RSM). A Central Composite Design (CCD) with three factors was used to study the effects of carrageenan (0.1-0.2%), gum Arabic (0.1-1.0%) and corn starch (1.5-2.5%) on … …American Journal of Applied Sciences, Vol. 12, Issue 1 · 11 Mar 2015 · 8,194 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy on the Enhancement of Hypoglycemic and Antioxidant Activities of Compound Herbal Tea through Solid-State FermentationQing Liu, Xiaowen Que, Yueping Yang et al.This study utilized Aspergillus niger KY2295 for the Solid-State Fermentation (SSF) of a compound tea made from Cinnamomum cassia bark, Glycyrrhiza glabra, Morus abla L. leaf, and Crataegus oxyacantha L. to enhance its hypoglycemic effects. The fermentation process was optimized using single-factor experiments and a Central Composite Design (CCD), with α-amylase and α-glucosidase inhibitory activities as evaluation indices. Following fermentation, … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 1 · 20 May 2025 · 5,473 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization and Molecular Identification of Protease-Producing Thermophilic Bacterial Isolate TUA-26Anthoni Agustien, Mufidhatul Muqarramah, Feskaharny AlamsjahProtease enzymes are used as biocatalysts that can accelerate a reaction. Thermostable enzymes produced by thermophilic bacteria are needed in the industrial field because of their ability to withstand high temperatures. The thermophilic bacterial isolate TUA-26 that produces protease was to analyze the optimum conditions of temperature, pH, agitation, trace elements, carbon sources, and nitrogen sources; the stability of protease … …OnLine Journal of Biological Sciences, Vol. 24, Issue 3 · 6 Apr 2024 · 4,935 accessesView PDFCite
Research ArticleOpen accessIn the abstractRecovery of Manganese from Zinc Smelter SlagRasoul Khosravi, Rasoul Fatahi, Hossein Siavoshi, Fatemeh MolaeiUsing a software-based experiment design, the application of the leaching process for the extraction of manganese from Zinc Plant Slag (ZPS) was investigated. In this study, the effect of different parameters, i.e., H2SO4 concentration, pulp density, agitation rate, temperature and reaction time, was investigated. Response Surface Methodology (RSM) based on the Central Composite Design (CCD) has been implemented to consider … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 4 · 1 Dec 2020 · 7,273 accessesView PDFCite
Research ArticleOpen accessIn the abstractEquilibrium Studies and Optimization of Phosphate Adsorption from Synthetic Effluent Using Acid Modified Bio-SorbentBabayemi Akinpelu Kamoru, Onukwuli Okechukwu DominicAdsorption potential of periwinkle shell (PRW), an agricultural waste, for the removal of phosphate from aqueous solution was investigated through equilibrium studies at various experimental conditions. PRW was carbonized and chemically activated with 1MH2SO4 before it was subjected to characterization using Fourier Transform Infrared (FT-IR), Energy Dispersive X-ray (EDX) and Scanning Electron Microscopy (SEM). Adsorption data were analyzed using various … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 4 · 15 Dec 2017 · 7,666 accessesView PDFCite
Research ArticleOpen accessIn the abstractThermodynamics, Non-Linear Isotherms, Statistical Modeling and Optimization of Phosphorus Adsorption from WastewaterAkinpelu Kamoru BabayemiPalm Kernel Shell (PKN), an eco-friendly biomass, was carbonized and activated for the removal of phosphorus from wastewater through batch adsorption process. The studies evaluate the effects of pH, particle size, dosage and contact time on the adsorption capacity of the prepared adsorbent. The equilibrium concentration data and the amount of adsorption were described using non-linear regression analysis of the … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 19 Nov 2016 · 7,512 accessesView PDFCite
