This study investigated the protective effects of a polyphenol-rich extract from the halophyte <i>Polygonum maritimum</i> L.

Its formation primarily occurs through the Maillard reaction and is strongly influenced by processing parameters. This review aims to synthesize current evidence on how temperature, time, and moisture conditions during thermal processing affect acrylamide formation in grain-based products, with an emphasis on jointly evaluating these key processing parameters. Beyond describing formation mechanisms, the review highlights the dietary contribution of these products to consumer exposure and evaluates how processing parameters translate into variations in intake levels. By providing comparative evidence across various cooking practices, this work supports the optimization of processing conditions and identifies critical gaps in integrating\"temperature–time–moisture\" relationships and consumer exposure. Ultimately, this review offers a unified, process-based perspective, providing practical recommendations for both industrial stakeholders and public health optimization. Acrylamide levels generally increase with higher temperatures, longer heating times, and reduced moisture, particularly in dry-heat methods such as baking, frying, and roasting. Although some studies report a decline in acrylamide at extreme temperatures, these conditions typically compromise product quality, and research on this phenomenon remains limited. Moisture plays a critical role: lower-temperature, moist-heat treatments tend to inhibit acrylamide formation, while prolonged high-temperature exposure promotes it. Understanding the interaction between temperature, time, and moisture during cereal processing is crucial for effectively reducing acrylamide formation while maintaining product quality.

The effectiveness and scalability of a number of different production methods, including the culture of microalgae and the utilization of modern extraction techniques, such as supercritical carbon dioxide and deep eutectic solvents, are being examined. Studies have shown that astaxanthin is up to 550 times more powerful than vitamin E and 11 times more powerful than beta-carotene when it comes to combating particular free radicals. The effectiveness of astaxanthin varies depending on the sort of oxidative damage that is being tested; however, it is consistently ranked as a stronger antioxidant, particularly in terms of its capacity to preserve cell membranes and quench singlet oxygen. Astaxanthin improves the pigmentation, immunity, and growth of aquatic organisms, which in turn helps aquaculture. It also extends the shelf life of food and improves its sensory quality. Natural sources provide astaxanthin, a powerful antioxidant in the health, wellness, and nutrition markets.
