Development and Evaluation of Low‐Fat Fish and Chicken Nuggets Fortified With Date Seed Powder and Quinoa Flour as Agricultural Dietary Fiber Sources

In recent years, high-oil-content fried products, such as nuggets, have posed a significant challenge and concern for consumers, leading to increased interest in fiber-enriched meat alternatives that offer specific functional properties and health benefits. This study investigated the incorporation of quinoa flour and date seed powder as fiber sources into chicken and fish paste formulations at a 6% concentration, with varying ratios of quinoa flour to date seed powder: 0:0 (T1), 100:0 (T2), 75:25 (T3), and 50:50 (T4). The results demonstrated that adding these ingredients markedly improved the dietary fiber content, water holding capacity, cooking yield, and pH levels of the nuggets (<i>p</i> < 0.05). Notably, the T4 treatment exhibited the lowest oil absorption (3.82 g for chicken and 5.19 g for fish per 100 g of product) among all formulations (<i>p</i> < 0.05). The fiber-enriched nuggets exhibited noticeable differences in texture and color. Additionally, the incorporation of quinoa flour and date seed powder positively influenced the sensory attributes of the nuggets, with T3 achieving the highest overall acceptance score. This formulation was identified as the most favorable option for both chicken and fish nuggets, owing to its optimal cooking yield, high acceptance, adequate fiber content, and minimal oil absorption.
