This study demonstrates the eco-friendly enzymatic debranching of starch from various sources, utilizing pullulanase and isoamylase enzymes. The process improves starch digestibility, enhances texture and stability, and increases glucose yield, with broad applications in the food industry, pharmaceuticals, and industrial sectors.

Biopolymer and its sustainable use in remediation of pollutants.

Starch isolated from N. lotus seed demonstrates the lowest paste clarity. N. lotus rhizome starch demonstrates a lower storage and loss modulus than seed. N. lotus rhizome starch has shown a higher shear stress and apparent viscosity. The onset and peak temperature of N. lotus rhizome are lower than seed.

Lotus starches, that is, lotus seed starch (LS) and lotus rhizome starch (LRS) were comparatively characterized with mung bean starch (MBS) and potato starch (PS) based on physicochemical, pasting, morphological, structural, thermal, and rheological properties. The LS had the highest amylose content, but LRS showed the lowest value. The LS, LRS, and MBS exhibited typical A-type, while PS showed B-type pattern. MBS and PS showed higher transition temperatures than LS and LRS.

Chitosan-based hydrogel was used to carry insulin, then it was coated by starch films (prepared by A-, B-, and C-type starches at different glycerol contents) to regulate the release process of insulin in the simulated stomach and intestine, respectively. The results showed that pea starch film exhibited the best water-blocking properties when the glycerol content was 4% (w/v). And the potato film showed the best advantage in protecting the insulin-loaded hydrogel in the stomach and controlling the release of insulin in the intestine.

High concentrations of pigment powder dispersion stability are always a difficult problem in the cosmetics technology. It is necessary to improve iron oxide yellow dispersion and suspension stability of the paste to facilitate the application of iron oxide yellow powder in the cosmetics industry. In this study, octenyl succinate starch (OSA starch) and Arabic gum (AG) were used as composite wall materials to encapsulate iron oxide yellow and to find the best solution for the water-soluble pigment powder dispersion system.

This flowchart presents a comprehensive experimental procedure for the production and evaluation of these novel bioactive films. It encompasses the entire process, including the extraction and processing of saffron corm starch (SCS), and the production of lignin (CL), and carboxymethyl cellulose (CMC) from corn husk waste. The flowchart also highlights various analysis techniques that outline the characterization processes, enabling the evaluation of the films' properties and performance.

How the amylose is leached out during gelatinization determines the mechanical response during storage. Low-viscosity potato starch produced strong gels, presumably because of its native molecular order.

Physical modification of Buckwheat starch by microwave treatment improve its amylose content and water absorption capacity, while reduce its syneresis, crystallinity, short-range structure, and pasting properties (peak, trough, breakdown, and final viscosities).

Unscrupulous merchants often add other inexpensive starches to lotus rhizome starch to reduce costs and seek profits, resulting in changes to the properties of starch. In this study, ten commerically available lotus rhizome starch samples were analyzed to obtain micrographs of their particles using an optical microscope, and their authenticity was verified. By measuring their physicochemical properties, including retrogradation and gelatinization characteristics, the differences in properties between genuine and adulterate lotus rhizome starch were compared.

Extraction and purification of the natural polymer, nonstarch carob galactomannan (LBG), from Algerian carob seeds for industrial use. In order to obtain an efficient extraction of this biopolymer with high quality, the choice of the aqueous extraction method is important. Characterization results reveal crucial information for maximizing efficiency, making it suitable for diverse applications in food, biomedical, and other industries.
