Production of Whey-Derived DPP-IV Inhibitory Peptides Using an Enzymatic Membrane ReactorSpringer Science and Business Media LLC - Tập 12 - Trang 799-808 - 2019
John O’Halloran, Michael O’Sullivan, Eoin Casey
Continuous processing in the production of peptides is an area of increased interest. In this study, an enzymatic membrane reactor (EMR) was developed whereby whey protein isolate was used as a substrate to prepare DPP-IV inhibitory and radical scavenging peptides via enzymatic hydrolysis. Two separate enzymes were tested: Corolase 2TS and Protamex in conventional batch processes and the EMR. Neit...... hiện toàn bộ
Optimization and Characterization of Porous Starch from Corn Starch and Application Studies in Emulsion StabilizationSpringer Science and Business Media LLC - Tập 15 - Trang 2084-2099 - 2022
Sannya Sathyan, P. Nisha
Preparation of porous starch (PS) from corn starch (NS) using enzymes amylase (AM) and amyloglucosidase (AMG) was standardized using two factorial experimental design in terms of surface area and pore size distribution. SEM micrographs confirmed the formation of porous structures in the granules. Based on surface area, pore size and statistical analysis 300 U AM and 250 U AMG for 6 h incubation we...... hiện toàn bộ
Antifungal Activity of a Chitosan and Mint Essential Oil Coating on the Development of Colletotrichum Gloeosporioides in Papaya Using Macroscopic and Microscopic AnalysisSpringer Science and Business Media LLC - Tập 15 - Trang 368-378 - 2022

Chitosan and mint essential oil treatments have been studied as natural alternatives to chemical fungicides to control fruit diseases caused by phytopathogens, such as Colletotrichum gloeosporioides that causes anthracnose in papaya fruit; however, their combination has been scarcely studied and their microscopic effect on the infected papaya surface has not been reported. The aim of this investig...... hiện toàn bộ
The Inactivation Kinetics of Soluble and Membrane-Bound Polyphenol Oxidase in Pear during Thermal and High-Pressure ProcessingSpringer Science and Business Media LLC - - 2018
Lei Zhou, Wei Liu, Netsanet Shiferaw Terefe
Polyphenol oxidase (PPO) from pear was characterized with catechol as substrate. The Michaelis constant of soluble and membrane-bound PPO were 15.6 and 23.8 mM, respectively, and their optimum pH for activity were 6.0 and 6.5, respectively. The inactivation kinetics of soluble and membrane-bound PPO during thermal (45–75 °C) and high-pressure thermal processing (600 MPa, 40–80 °C) were studied. Th...... hiện toàn bộ
Mango Seed Kernel: A Bountiful Source of Nutritional and Bioactive CompoundsSpringer Science and Business Media LLC - Tập 16 - Trang 289-312 - 2022

Mango (Mangifera indica L.) is grown worldwide and widely accepted by consumers for its sweet taste and exotic flavor. During consumption and processing of mango, a large quantity of by-products in the form of peel and seeds are generated and generally discarded as waste. Mango waste generated at domestic and industrial levels requires attention and proper solution for its disposal and value addit...... hiện toàn bộ
Kinetic Modeling of Amino Acid Production from Ice-Cream Wastewater in Subcritical ConditionsSpringer Science and Business Media LLC - Tập 14 - Trang 717-725 - 2021
Maryam Enteshari, Sergio I. Martinez-Monteagudo
Wastewater derived from ice-cream manufacture contains high concentration of protein, making it a suitable feedstock for hydrolysis. In this study, ice-cream wastewater was hydrolyzed under subcritical conditions (170–230 °C and 40 bars) and different nominal pH (3, 6, and 9) to produce amino acids. The formation and subsequent degradation of amino acids were modeled using a two-consecutive reacti...... hiện toàn bộ
Optimization of Supercritical Carbon Dioxide Extraction of Bioactive Flavonoid Compounds from Spearmint (Mentha spicata L.) Leaves by Using Response Surface MethodologySpringer Science and Business Media LLC - Tập 5 - Trang 912-920 - 2011
Mandana Bimakr, Russly Abdul Rahman, Ali Ganjloo, Farah Saleena Taip, Liza Md Salleh, Md Zaidul Islam Sarker
The bioactive flavonoid compounds of spearmint (Mentha spicata L.) leaves were obtained by using supercritical carbon dioxide (SC-CO2) extraction. Extraction was carried out according to face-centred central composite design, and independent variables were pressure (100, 200 and 300 bar), temperature (40, 50 and 60 °C) and co-solvent amount (3, 6 and 9 g/min). The extraction process was optimized ...... hiện toàn bộ
