Article Abstract
This study investigated the effects of plasma-activated water (PAW) assisted annealing and heat-moisture treatment (HMT) on the physicochemical, structural properties, and in vitro digestibility of Tartary buckwheat starch (TBS). The results showed that there were much aggregates on the surface of starch granules under annealing and HMT conditions, it was more pronounced when subjected in PAW. The modified starches showed higher R and pasting temperature, which led to reducing digestibility of TBS. Notably, the highest resistant starch content (71.08 %) was observed with PAW-HMT under the moisture content of 30 %. In addition, all the modified starches remained A type pattern except HMT and PAW-HMT samples, which displayed an A + V type pattern. Therefore, TBS was more sensitive to the combined HMT and PAW treatment. These findings offered valuable insights into the application of PAW combined with thermal treatments to enhance the quality of TBS in the utilization of functional foods.

Unmodified starches and flours have physicochemical and functional limitations that include low solubility, limited swelling power, low water absorption, and a high tendency to retrogradation and syneresis-characteristics that restrict their use in the agri-food industry. To overcome these limitations, several physical modifications have been proposed, such as hydrothermal treatments (heat-moisture treatment, HMT; dry-heat treatment, DHT; and annealing, ANN), as well as extrusion and the use of microwaves. HMT, DHT, and ANN are processes that are performed at low, intermediate, and high-moisture content, respectively.

The applications of hydrothermally modified starches in conventional water media, such as distilled water (DW), are limited due to their poor performance. Therefore, researchers are introducing innovative techniques in various environments, including ethanol solutions, salt solutions, acidic or alkaline conditions, plasma-activated water (PAW), and hydrogen-infused water (HW), to enhance the efficiency of annealing (ANN) and heat moisture treatment (HMT). The present review discusses these new approaches aimed at improving the performance of ANN and HMT, their potential mechanisms for starch modification, the resulting changes in the functional properties of starch, and their role in various food applications.

Red rice flours performed modification using sustainable techniques, including ANN (annealing), HMT (heat moisture treatment), US (ultrasound), Pregel (Pregelatinization), WM (wet-microwave treatment), and DM (dry-microwave treatment). Manpo rice flour, which is high in amylose, demonstrated higher peak viscosity compared to flours from medium-high amylose rice (Hommali rice), under the same treatment conditions. The reduction in swelling power observed after ANN and HMT treatment in both varieties corresponds with the pasting behaviors of these flours.

Six green modification techniques, including annealing (ANN), heat moisture treatment (HMT), pregelatinization (Pregel), ultrasound (US), wet-microwave (WM), and dry-microwave (DM), were applied to modulate the properties of rich-polyphenol low-amylose rice flour. WM produced more stable flour paste with the highest peak viscosity (246.83 ± 7.
