Enhancing the Stability of Wax-Based Oleogels Through Post-Process Thermal Treatments: A Comparative Study of Conventional, Microwave, and Infrared Heating Techniques K. Sandhya, C. K. Sunil, Venkatachalapathy Natarajan Journal of Food Process Engineering, 2026 Oiling out remains a major limitation affecting the storage stability of wax‐based oleogels. This study investigates the influence of post‐process thermal treatment using microwave (MW) and infrared (IR) heating on the structural and stability characteristics of sunflower wax (SFW)‐based oleogels formulated with chia seed oil (CSO) and groundnut oil (GNO) (95%–97% oil content). Compared to conventionally prepared oleogels, MW‐treated samples exhibited significantly enhanced rheological behavior, firmness, and thermal stability. The post‐process thermal treatments promoted melting followed by recrystallization, resulting in improved crystal network organization. Image analysis of polarized light micrographs using ImageJ software revealed a significant reduction in the inter‐crystalline void fraction, indicating the formation of a denser crystalline network. A reduction of approximately 66% in porosity and 65% in crystal size was observed, leading to the formation of a compact three‐dimensional network. XRD analysis further indicated orthorhombic subcell network after MW treatment. DSC thermograms showed significantly higher melting enthalpies, reflecting improved thermodynamic stability. Although higher wax concentrations improved gel strength, post‐treatment using MW was more effective in enhancing structural stability. These findings demonstrate the potential of MW‐assisted post‐processing as an efficient strategy to improve the integrity and application of SFW‐based oleogels as healthier fat replacers.
Impact of Hydrocolloids on Functional and Rheological Properties of Pearl Millet Flour: Textural, Sensory Attributes, and In Vitro Digestibility of Pearl Millet Balls Pratik Pande Prakash, Chandrasekar Veerapandian, G. Suba, Subhasri Dharmaraj, C. K. Sunil, et al. Journal of Food Process Engineering, 2026 Pearl millet balls (PMB) were developed to counteract tapioca balls (TB), which are made up of starch. However, the PMB were less accepted by consumers due to their poor textural properties, particularly in terms of surface integrity. To improve the properties and consumer acceptability, hydrocolloids, namely carboxy methyl cellulose (CMC—water‐soluble, cellulose‐derived polymer), hydroxypropyl methyl cellulose (HPMC), and guar gum (GG), were added to pearl millet flour at three proportions (0.5, 1, and 2 g parts of hydrocolloid per 100 parts of flour). The hydrocolloids added to the flour altered its characteristics and textural and sensory properties, as well as the in vitro digestibility of the balls. The addition of hydrocolloids significantly reduces starch digestibility in PMB by increasing viscosity, which was revealed in a rheological study. Hydrocolloid‐added pearl millet balls showed an absence of cracks and fissures, with 2 g of CMC/100 g of PMF having optimal hardness (908–2064 g) and minimal cooking loss (4.86%–5.14%). Rapidly digestible starch declined from 62% to 46% when studied in combination with hydrocolloids. Carboxymethyl cellulose (2 g) added PMB showed a similar resemblance to TB, as indicated by their pasting properties, rheological studies and sensory analysis, with higher consumer acceptance than the 0.5 and 1 g concentrations. These hydrocolloids added to PMB exhibited better textural properties and were consumer acceptable.
Evaluation of Drying Kinetics and Quality Assessment of Desiccated Coconut Produced by Conventional Hot-Air Drying Method Panoth Abhirami, Taruna Varghese, C. K. Sunil, Venkatachalapathy Natarajan Journal of Food Process Engineering, 2026 This study examined the drying kinetics and quality of desiccated coconut through hot‐air drying at varying temperatures of 80°C, 85°C, and 90°C, reducing moisture content from 48% ± 2% (w.b.) to 2% ± 1.1% (w.b.). Several physicochemical parameters were assessed, including color, water activity, energy consumption, oil characteristics, surface morphology, functional groups, and fatty acid profiles. The findings revealed that drying temperature significantly affected the color attributes of the coconut, primarily driven by the Maillard reaction and sugar concentration, with desiccated coconut at 85°C demonstrating optimal color properties. Water activity consistently decreased with increasing drying temperature. Higher drying temperatures resulted in a notable reduction of free fatty acids (FFAs); however, the peroxide value of the extracted oil displayed an inverse correlation. Microstructural observations indicated that extended drying resulted in pore formation due to moisture evaporation, with 90°C exhibiting an oily surface indicative of oil cell breakdown absent at 85°C. Additionally, lauric acid content increased with drying temperature. FTIR analysis revealed distinct O–H stretching vibrations, alongside C–H and C═O stretching bonds, confirming the presence of carbohydrates and ester groups in coconut fat. Thus, optimizing the drying process at 85°C is recommended for improving the quality of desiccated coconut, suitable for industrial applications.
