Abstract

The potential to directly fortify food products using extracts obtained through green solvents is both innovative and promising. In pursuit of this goal, this study evaluated the possibility of directly fortifying spreadable chocolate with an optimized carotenoid-rich Natural Hydrophobic Deep Eutectic Solvent (NaHDES) extract formulated with monoterpenes. The optimized extract (3.545 ± 0.126, 3.341 ± 0.023, and 0.049 ± 0.001 mg/mL for total carotenoids, β-carotene and lutein, respectively) was obtained using a thymol/DL-menthol molar ratio of 1:4, a solvent:sample ratio of 10 (v/w), and an extraction time of 30 min. Subsequently, commercial no-sugar-added spreadable chocolate was fortified with the selected extract at 14 and 28 % (v/w). The fortified products were analyzed for carotenoid content, antioxidant activity, physicochemical and textural properties. The findings revealed that the lower extract addition minimally impacts the investigated characteristics of spreadable chocolate. Considering the preserving effect of the selected NaHDES on carotenoids and antioxidant activity, this innovative approach holds great promise for enhancing fortified food products' nutritional value and stability.

优化类胡萝卜素 NaHDES 提取，提高涂抹巧克力的营养价值

利用通过绿色溶剂获得的提取物直接强化食品的潜力既具有创新性，又大有可为。为了实现这一目标，本研究评估了用优化的富含类胡萝卜素的天然疏水深共晶溶剂（NaHDES）提取物配制单萜直接强化涂抹巧克力的可能性。采用百里酚/DL-薄荷醇摩尔比为 1:4，溶剂与样品比为 10（v/w），萃取时间为 30 分钟，得到了优化提取物（总类胡萝卜素、β-胡萝卜素和叶黄素的含量分别为 3.545 ± 0.126、3.341 ± 0.023 和 0.049 ± 0.001 mg/mL）。随后，将所选提取物以 14% 和 28% （体积分数）的比例添加到商用无糖涂抹巧克力中。对强化产品的类胡萝卜素含量、抗氧化活性、理化和质构特性进行了分析。研究结果表明，较低的提取物添加量对所研究的可涂抹巧克力特性的影响很小。考虑到所选 NaHDES 对类胡萝卜素和抗氧化活性的防腐作用，这种创新方法在提高强化食品的营养价值和稳定性方面大有可为。
