Article Abstract
Peanuts are highly nutritious but pose a significant risk of triggering food allergies. While heat treatment can reduce the allergenicity of many foods, it may also alter their structure, potentially impacting detection results. This study employed double antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA) and lateral flow immunochromatography (LFIA) to evaluate the allergen Ara h 3 following heat-moisture treatment. DAS-ELISA achieved a detection limit of 39.06 ng/mL, with inter-plate and intra-plate coefficients of variation below 3.05 % and 6.79 %, respectively, and recovery rates ranging from 78.48 % to 90.93 %. LFIA, with a detection limit of 1.6 μg/mL, demonstrated high sensitivity, stability, and no cross-reactivity with other proteins. Both methods were effective in detecting peanut-processed products, with heat-moisture treatment significantly reducing Ara h 3 antigenicity, making them valuable tools for assessing desensitization in food production.

The development of sustainable and functional emulsifying systems has become increasingly important in both agri-food and industrial applications, driven by regulatory restrictions on synthetic emulsifiers and the growing demand for natural alternatives such as cassava starches and coconut oil. This study explored the structural, morphological, and techno-functional properties of complexes formed between native and heat-moisture-treated (HMT) starches and short-chain fatty acids prepared under ultrasonic cavitation, and assessed their effectiveness as stabilizing agents in Pickering emulsions. HMT significantly enhanced the complexing index to 71.

Background/objective: Heat-moisture treatment (HMT) can increase the composition of resistant starch and reduce the glycemic index in rice. However, the effect of long-term HMT-rice feeding is unknown. The objective is to investigate the effect of long-term HMT-rice feeding on alleviating hyperglycemia in mice and explore potential mechanisms.

Dual-physical modification is an eco-friendly and waste-free approach for enhancing the functionality of native starches compared with a single modification. In the present study, the individual and combined interrelating effects of hydrothermal (heat moisture (HM) with 15%, 20%, and 25% moisture) and non-thermal (ultrasonication (US) with 200, 400, and 600 power (W)) on the physical modification of (Chinese water chestnut (CWCS)) starch were studied. Furthermore, their effects on the morphology, FTIR, XRD, crystallinity, thermal, pasting, swelling power, solubility, rheological characteristics, and in vitro digestibility of native and modified starches were investigated.

High-amylose wheat (HAW), developed through non-genetic modification, addresses the growing demand for clean-label and nutritionally enhanced food products. This study systematically investigated the effects of heat-moisture treatment (HMT; 20% and 25% moisture levels) on the physicochemical properties and cookie-making performance of HAW flour (HAWF) and soft wheat flour (SWF). HMT promoted moisture-induced agglomeration, leading to increased particle size, reduced damaged starch content, and enhanced water and sucrose solvent retention capacities.
