Multi-Scale Structural Insights into Enzymatically Hydrolyzed Lentil Starch Concentrates Prepared by In Vitro Method Using Different Types of Enzymes.

This study was undertaken to investigate the enzymatic hydrolysis of lentil starch concentrates from conventional cooked seeds (CCLSC) by the action of different types of enzymes, including pancreatin (PC-EHSC), heat-stable α-amylase (HS-EHSC), β-amylase (βA-EHSC), amyloglucosidase (AMG-EHSC), and multi-enzymes (βA-HS-AMG-EHSC); their multi-scale structural characteristics of the enzymatic hydrolysis products of lentil starch concentrates were compared. The morphological features distinguished among different samples. The Fourier-transform infrared spectroscopy and solid-state C CP/MAS NMR spectral features indicated the possible formation of a binary and ternary complex among amylose, protein and lipids.

C1 effectively inhibits : Effects of antimycotic culture supernatant on toxin synthesis and corresponding gene expression.

Recently, consumers are increasingly concerned about the contamination of food by molds and the addition of chemical preservatives. As natural and beneficial bacteria, probiotics are a prospective alternative in food conservation because of their antimycotic activities, although the mechanism has not been explained fully at the level of metabolites. This study aimed at investigating the antifungal activities and their mechanisms of five potential probiotic strains ( C1, M8, L6, M1, and M4) against , the common type of mold growth on the bread.

Preparation of rutin-loaded microparticles by debranched lentil starch-based wall materials: Structure, morphology and in vitro release behavior.

Different treatments of autoclaving, pullulanase debranching and/or ultrasound were applied to prepare debranched lentil starch (DBLS). Their fine structures can affect the retrogradation patterns of DBLSs, which consequently could affect their potential use as delivery carrier of sensitive bioactive compounds. An attempt was made to use these DBLSs as wall materials to encapsulate rutin, aiming to improve the bioaccessibility, meanwhile to enhance the aqueous solubility and stability of rutin molecules.

Insights into the supramolecular structure and techno-functional properties of starch isolated from oat rice kernels subjected to different processing treatments.

Oat rice kernels were subjected to decortication (DOR), decortication and enzyme deactivation (DDOR), decortication and cooking (DCOR), as well as combined decortication, enzyme deactivation and cooking (DDCOR). The starch fractions were isolated and their structural features were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, solid-state C nuclear magnetic resonance, small angle X-ray scattering (SAXS), and scanning electron microscope. In the cooked oat rice samples (DCOR and DDCOR), in addition to losing a significant amount of the A-type crystalline structure, there was an enhancement in the proportion of V-type crystallinity.

Understanding the multi-scale structural changes in starch and its physicochemical properties during the processing of chickpea, navy bean, and yellow field pea seeds.

This study aimed to isolate starch from three types of untreated and autoclaved pulse seeds including chickpea, navy bean, and yellow field pea and to characterize their multi-scale structure and the associated physicochemical properties. Autoclaving of pulse seeds tended to significantly decrease the relative crystallinity, the M value, and degree of order of starch samples measured by X-ray diffraction, size exclusion chromatography, and FT-IR. Simultaneously, double helix content, and degree of double helix obtained from solid-state CNMR and FT-IR were relatively higher (P < 0.
