“…Starches derived from various sources exhibit notable variations in granule shape, size, and surface structure under SEM. For instance, potato starch appears spherical with a smooth surface, corn starch exhibits a polyhedral shape with a rough surface, while mung bean starch displays a kidney-shaped morphology with a smooth surface [41][42][43][44][45]. Li et al [46] acidified waxy maize starch using HCl and then subjected it to dry heat treatment within a temperature range of 140 °C to 200 °C.…”

With the escalating prevalence of diabetes and obesity, resistant dextrin, renowned for its prebiotic properties and blood glucose-lowering physiological activity, has garnered significant attention. Resistant dextrin, a low-calorie, indigestible water-soluble dietary fiber processed from starch, has high solubility, low molecular weight, and good thermal stability. The established method for its preparation involves a combination of acid heat treatment and enzymatic purification. Within the human body, resistant dextrin confers numerous health benefits. It promotes a balanced intestinal microbiome, regulates blood glucose and lipid metabolism, and enhances satiety. Additionally, it exerts positive influences on the intestinal environment, aids in weight management, and alleviates chronic conditions, particularly diabetes. In the food industry, resistant dextrin is widely employed as a functional food additive to enhance the nutritional value and health benefits of various food products. However, there is a need for greater clarity regarding the structural characteristics of resistant dextrin and the potential interplay between its structure and physiological activity. This paper comprehensively reviews the preparation methods, structural properties, health benefits, and application areas of resistant dextrin. Additionally, it anticipates future trends in its development. The primary objective of this review is to offer theoretical guidance and fresh perspectives for further research, the innovation of functional products, and the expanded utilization of resistant dextrin.

“…The organic solvent method can improve the reaction efficiency, but the cost increases and it is toxic and easily causes environmental pollution [19]. Scientists have developed dry and semi-dry starch modification methods on this basis [20][21][22]. Zhu et al [23] investigated the effect of different starch moistures on solvent-free esterification reactions.…”

Filtrate reducer is a drilling fluid additive that can effectively control the filtration loss of drilling fluid to ensure the safe and efficient exploitation of oilfields. It is the most widely used treatment agent in oilfields. Due to its moderate conditions and controllable procedure, alkaline hydrolysis of high-purity waste polyacrylonitrile has been utilized for decades to produce filtrate reducer on a large scale in oilfields. However, the issues of long hydrolysis time, high viscosity of semi-finished products, high drying cost, and tail gas pollution have constrained the development of the industry. In this study, low-purity waste acrylic fiber was first separated and purified using high-temperature hydroplastization, and the hydrolyzed product was obtained using alkaline hydrolysis with the micro-water method, which was called MW−HPAN. The hydrolysis reaction was characterized using X-ray diffraction, scanning electron microscopy, infrared spectroscopy, and thermogravimetric analysis, and the elemental analysis showed a hydrolysis degree of 73.21%. The experimental results showed that after aging at 180 °C for 16 h, the filtration volume of the freshwater base slurry with 0.30% dosage and 4% brine base slurry with 1.20% dosage was 12.7 mL and 18.5 mL, respectively. The microstructure and particle size analysis of the drilling fluid gel system showed that MW−HPAN could prevent the agglomeration of clay and maintain a reasonable particle size distribution even under the combined deteriorating effect of high temperature and inorganic cations, thus forming a dense filter cake and achieving a low filtrate volume of the drilling fluid gel system. Compared with similar commercially available products, MW−HPAN has better resistance to temperature and salt in drilling fluid gel systems, and the novel preparation method is promising to be extended to practical production.

BACKGROUNDThe preparation of malic acid starch ester (MSE) is mostly carried out using a high temperature method, but there are problems such as high energy consumption, long preparation time, and uneven heating. Microwave technology can be used to overcome these limitations. The semi‐crystalline structure of starch granules hinders the modifier's access to the matrix, thus limiting the esterification reaction. Physical techniques can act on the interior of the starch to create a number of active sites, thereby facilitating the reaction of the starch with esterification reagents. Therefore, this study investigated the effect of starch pretreatment by microwave, heat‐moisture, and ultrasonic techniques on the degree of substitution (DS), structure, and physicochemical properties of MSE synthesized by the microwave method.RESULTSThe DS of MSE was increased after pretreatments. The modified starch obtained by different pretreatment methods did not show new characteristic peaks, while the MSE synthesized showed new absorption peaks near 1735 cm−1. The granular structure and morphology of the modified starch obtained by microwave and heat‐moisture pretreatment were gelatinized and aggregated, while some of the starch particles of the modified starch obtained by ultrasonic pretreatment appeared pore‐sized. The relative crystallinity and gelatinization enthalpy of the MSE were reduced, but the crystallization pattern remained as A‐type.CONCLUSIONOverall, the results suggest that various pretreatment methods can enhance the DS of MSE by disrupting the structure of starch. The findings of this study provide theoretical support for improving the DS of esterified starch. © 2024 Society of Chemical Industry.
