Antioxidant activity was evaluated utilizing … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 2 · 30 Jul 2026 · 655 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTime Series Analysis for Predicting Tea Harvest Yield: A SARIMAX-Based ApproachPallavi Nagpal, Deepika Chaudhary, Jaiteg SinghPrecise prediction of tea yield is crucial for both agricultural planning and economic forecasting. Projection of the future trends, which rely on present and historical data, is the process termed 'forecasting'. Yield prediction is fundamental for research and development. By gathering the yield data over historic times, the researchers can make their work more valuable by predicting the yield patterns. … …Journal of Computer Science, Vol. 22, Issue 2 · 19 Feb 2026 · 1,891 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleStudy 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 accessEvery word in the titlePhytochemical Profiles and Anti-Diabetic Potential of the Extract of Pueraria lobata Compound Teabags: Preparation and Optimization Infusion ConditionsQing Liu, Wenyue Shi, Futing Xue et al.A Pueraria lobata root compound teabag using Pueraria lobate root, Stigma maydis, and Prunus mume as the main material was prepared in this study, and the brewing technology was optimized using Response Surface Methodology (RSM). The sensory evaluation, total polysaccharide, and phenolic compound content were used as evaluation indicators and the effect of the compound ratio of raw material was … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 4 · 26 Nov 2022 · 5,641 accessesView PDFCite
