Item Metadata only Effects of different edible oils on in vitro starch digestibility and physical properties of rice starch and rice flour(2023-01-01) Pinyo J.; Wongsagonsup R.; Panthong N.; Kantiwong P.; Huang Q.; Tangsrianugul N.; Suphantharika M.; Mahidol University), and soybean oil (SO) on the in vitro starch digestibility and physical properties of rice starch and rice flour. Each edible oil (10% w/w) was transferred to rice starch and rice flour and cooked at 95 °C for 8 min. The contents of rapidly digestible starch... and resistant starch in both cooked rice starch and rice flour were reduced and increased, respectively, by the addition of all edible oils, especially the CO and PO. The cooked rice starch and rice flour with added CO and PO had higher melting temperaturesPublication Open Access Spray dried rice starch: powder mixing in direct compression formulation(1998) Ampol Mitrevej; Nuwat Visavarungroj; Nuttanan Sinchaipanid; Pornnapa Mahapattanakul; อำพล ไมตรีเวช; ณวัฒน์ วิศวรุ่งโรจน์; ณัฐนันท์ สินชัยพานิช; Mahidol Univesity.

Faculty of Pharmaceutical SciencesPublication Metadata only Influence of octenyl succinate rice starch on rheological properties of gelatinized rice starch before and after retrogradation(2008-06-01) Tuangporn Tukomane; Saiyavit Varavinit; Mahidol UniversitySteady-shear rheological properties, including the consistency index from the power law, the yield stress and Casson plastic viscosity from the Casson's model were employed in the study of retrogradation of native rice starch, octenyl succinate (OS...) rice starch and blends containing up to 80% OS rice starch. After cold storage at 4°C for 24 h, presence of OS rice starch reduced retrogradation of rice starch mixtures as indicated by reduction of measured retrogradation parameters based on the threePublication Metadata only Confocal laser scanning microscopy of dextran-rice starch mixtures(2012-01-04) Piyada Achayuthakan; Manop Suphantharika; James N. Bemiller; Suan Sunandha Rajabhat University; Mahidol University; Purdue UniversityThe microstructure of rice starch and dextran-rice starch mixtures was studied using confocal laser scanning microscopy (CSLM) and scanning electron microscopy (SEM). Surface pores and channels of rice starch were looked for. Channels could... not be found in rice starch granules after reaction with 3-(4-carboxybenzoyl)-quinoline-2-carboxaldehyde (CBQCA). Fluorescein-labeled dextran was mixed with rice starch in order to locate hydrocolloid molecules in hydrocolloid-rice starch mixtures. The resultsPublication Metadata only Comparative study of pilot scale rice starch production by an alkaline and an enzymatic process(2005-04-01) Hatairat Puchongkavarin; Saiyavit Varavinit; Wolfgang Bergthaller; Mahidol University; Bundesforschungsanstalt fur Ernahrung und Lebensmittel; Inst. CerealRice starch is commonly isolated by alkaline (sodium hydroxide) extraction because this process provides high yield, high purity and is low in capital costs. This process produces an highly loaded alkaline effluent that contributes significantly... to general costs of wastewater treatment. The present study attempted to develop an enzymatic procedure to isolate pure rice starch and to investigate the physico-chemical properties in comparison with that of rice starch produced by an alkaline processItem Metadata only Influence of spent brewer's yeast [beta]-glucan on gelatinization and retrogradation of rice starch(Mahidol University. Mahidol University Library and Knowledge Center, 2006) Sripattra Satrapai; Manop SuphantharikaItem Metadata only Preparation and characterization of annealed-enzymatic hydrolyzed tapioca starch and the utilization in tableting and studies on the retrogradation of succinate rice starch and rice starches of various cultivars through the rheological property characterizations(Mahidol University. Mahidol University Library and Knowledge Center, 2023) Tuangporn Tukomane; Saiyavit VaravinitItem Metadata only Modification, characterization and utilization of various starch types and zeta potential for the determination of protein content of rice flour and degree of substitution of rice starch phosphates(Mahidol University. Mahidol University Library and Knowledge Center, 2023) Rungtiwa Wongsagonsup; Saiyavit VaravinitPublication Metadata only pH-induced Crosslinking of Rice Starch via Schiff Base Formation(2019-12-01) Narudom Srisawang; Saksit Nobsathian; Supa Wirasate; Chayanisa Chitichotpanya; Mahidol University© 2019, The Polymer Society of Korea and Springer. Rice starch is an abundant, inexpensive, and biocompatible biopolymer with a wide range of potential applications, particularly in the biomedical field. However, the use of rice starch is limited... of pH-induced crosslinking of rice starch without the use of any external chemical crosslinking agent was demonstrated. The crosslinked rice starch was prepared by forming a Schiff base reaction (imine) between the two modified starches: oxidized ricePublication Metadata only Characterization and utilization of acid-modified rice starches for use in pharmaceutical tablet compression(2003-10-01) Hatairat Puchongkavarin; Wolfgang Bergthaller; Sujin Shobsngob; Saiyavit Varavinit; Mahidol University; Federal Centre for Cereal, Potato and Lipid ResearchAcid modified, agglomerated starches offer specific advantages as fillers in production of pharmaceutical tablets. Spray drying can improve processing of tablet mixtures significantly. In order to investigate prerequisites in utilization of rice... starch, non-waxy and waxy types were partially hydrolyzed in 6% (w/v) HCI solution at room temperature for varied length of time to obtain rice starches with increased crystallinity (so-called crystalline rice starches).
