The storage characteristics of folic acid and NaFeEDTA fortified in a refractance window-dried turmeric powder base and its subsequent application to the formulation of nutritionally functionalized golden milk have not been addressed in previous studies. Golden milk is a staple food and ideal matrix for the fortification of important nutrients such as iron and folic acid. With this motivation, the present study assesses refractance window (RW)-dried turmeric powder fortified with folic acid and NaFeEDTA in terms of its moisture isotherm, permeability of packing material, and storage parameters to calculate its shelf life. Further, a sensory analysis was conducted based on the fuzzy logic method to obtain the best constitution of RW-dried turmeric powder in milk. For the best formulation of golden milk, the characteristics of the product under unrefrigerated and refrigerated conditions were evaluated in addition to the storage study. Additionally, moisture content (MC), total flavonoid content (TFC), total phenolic content (TPC), antioxidant activity (AA), curcumin content (CC), color indices, bulk densities, solubility, swelling power, and water binding capacities were studied with respect to time. The results demonstrated a healthy shelf life of 184, 187, and 183 days for RW-dried, folic acid-fortified, and NaFeEDTA-fortified RW-dried turmeric powder samples, respectively, in the zipper pouch system. The fuzzy scores ranked the sample with 1 g concentration of turmeric powder as the best, considering taste, aroma, mouthfeel, aftertaste, consistency, and overall acceptability. The TPC, TFC, AA, and CC values for RW-dried turmeric powder in milk were 876.21 mg GAE/100 mL, 784.61 mg quercetin/100 mL, 24.50% and 4.20% /, respectively. Marginal alterations were found for the RW-dried fortified and unfortified turmeric samples. This fortified golden milk has the potential for use as a health drink.
以往研究尚未涉及在折射窗干燥姜黄粉基质中强化叶酸和乙二胺四乙酸铁钠（NaFeEDTA）的储存特性，以及其随后在营养功能化金奶配方中的应用。金奶是一种主食，也是强化铁和叶酸等重要营养素的理想基质。出于这个动机，本研究评估了用叶酸和NaFeEDTA强化的折射窗（RW）干燥姜黄粉的水分等温线、包装材料的渗透性和储存参数，以计算其保质期。此外，基于模糊逻辑方法进行了感官分析，以获得牛奶中RW干燥姜黄粉的最佳组成。为了获得金奶的最佳配方，除了储存研究外，还评估了产品在未冷藏和冷藏条件下的特性。此外，还研究了水分含量（MC）、总黄酮含量（TFC）、总酚含量（TPC）、抗氧化活性（AA）、姜黄素含量（CC）、颜色指数、堆积密度、溶解度、膨胀力和水结合能力随时间的变化。结果表明，在拉链袋系统中，RW干燥姜黄粉样品、叶酸强化RW干燥姜黄粉样品和NaFeEDTA强化RW干燥姜黄粉样品的健康保质期分别为184天、187天和183天。考虑到味道、香气、口感、余味、稠度和总体可接受性，模糊评分将姜黄粉浓度为1 g的样品评为最佳。牛奶中RW干燥姜黄粉的TPC、TFC、AA和CC值分别为876.21 mg没食子酸当量/100 mL、784.61 mg槲皮素/100 mL、24.50%和4.20%。在RW干燥的强化和未强化姜黄样品中发现了微小变化。这种强化金奶有作为健康饮品使用的潜力。
