In this study, oxidized maltodextrins with a high concentration of carboxyl groups were produced using CuSO4 as catalyst and H2O2 an eco-friendly oxidant. Infrared spectroscopy, proton-nuclear magnetic resonance thermogravimetric analysis utilized to examine the structure properties maltodextrins. The reaction conditions optimized in terms oxidant content, temperature, pH, time. prepared maltod...

This research aimed to evaluate the viability, survivability, and release process of encapsulated Lactobacillus plantarum SU-LS36 in simulated gastric juice (SGJ), intestinal (SIJ), colon (SCJ). We tested four types encapsulations: native taro starch (NTS), modified (MTS) by heat moisture treatment (HMT), autoclaving-cooling-2 cycles (AC-2C), maltodextrin (commercial encapsulant). found that L....

The objective of this research was to evaluate some physicochemical and techno-functional properties mixtures Michigan bean protein concentrate: maltodextrin. beans were cleaned hulled, then dried (55 °C/1 h), ground obtain the flour, concentrate obtained by isoelectric precipitation technique. established based on preliminary tests with a maximum concentration 60% concentrate, 0:100, 9:91, 30:...

The difference in substrate selectivity of the maltodextrin (LamB) and sucrose (ScrY) porins is attributed mainly to differences in loop L3, which is supposed to constrict the lumen of the pores. We show that even a single mutation (D201Y) in loop L3 leads to a narrowing of the substrate range of ScrY to that resembling LamB. In addition, we removed the putative N-terminal coiled-coil structure...

The complete 796 residue amino acid sequence of maltodextrin phosphorylase was deduced from the E. coli malP nucleotide sequence. The calculated molecular weight of 90,500, including pyridoxal phosphate, is significantly larger than experimentally determined values. Enzymatically active and inactive mutants following deletion or exchange of up to 8 codons (7 amino acids) at the 3' end (C-termin...

Diaphania hyalinata, Plutella xylostella and Spodoptera eridania are considered important pests in vegetable crops, causing significant production losses. The most common method for managing these is the use of synthetic insecticides that cause chain damage, from human health to environment. A less aggressive alternative botanical insecticides, such as essential oils, which present themselves p...
