Gummy candies rely on sugar, gelatin, and synthetic colorants, but rising demand for natural alternatives makes replacement essential. Interactions between natural additives and main components (gelatin, sucrose), especially their effects on color and texture, remain unclear. This study examines the existence and amounts of sucrose, gelatin, and natural coloring agent, red beetroot extract powder (RBEP), in gummy candy compositions, along with main quality attributes and stability behavior. The effects of these variables on the main physicochemical, color, texture and bioactive properties were investigated. Model gummy samples' hardness (10.68-19.18 N), resilience (0.57-0.89), cohesiveness (0.87-1.01), springiness (0.19-0.54 mm), gumminess (9.63-21.30 N), and chewiness (2.15-8.29 N × mm) properties were determined by texture profile analysis. The values of , , , chroma, and hue angle were determined in the ranges of 23.9-91.5, (-0.93)-43.6, 1.06-8.17, 6.20-44.0, and 5.97-97.4, respectively. The interactions between RBEP × gelatin and RBEP × sucrose were found to be effective in color parameters. Total phenolic content (TPC) values and inhibition values for antioxidant activity (AA, % inhibition) ranged from 25.6 to 257.4 mg GAE/kg and 0.00-49.8%, respectively. The optimum composition, determined by considering texture properties and stability behavior as the response, revealed the concentrations of sucrose, gelatin solution, and RBEP as 34.53 g/100 g, 18.33 g/100 g, and 0.44 g/100 g, respectively. The study is the first to investigate the effect of RBEP concentration on the quality parameters of gummy candies and interactions with other components of the formulation. The results will raise awareness about the use of colorants in the confectionery industry and contribute to developing novel products.
软糖依赖于糖、明胶和合成色素,但对天然替代品的需求不断增加使得进行替代至关重要。天然添加剂与主要成分(明胶、蔗糖)之间的相互作用,尤其是它们对颜色和质地的影响,仍不明确。本研究考察了软糖组合物中蔗糖、明胶和天然着色剂红甜菜根提取物粉末(RBEP)的存在情况和含量,以及主要质量属性和稳定性行为。研究了这些变量对主要物理化学、颜色、质地和生物活性特性的影响。通过质地剖面分析测定了模型软糖样品的硬度(10.68 - 19.18 N)、弹性(0.57 - 0.89)、内聚性(0.87 - 1.01)、弹性(0.19 - 0.54 mm)、黏性(9.63 - 21.30 N)和咀嚼性(2.15 - 8.29 N×mm)等特性。L*、a*、b*、色度和色相角的值分别在23.9 - 91.5、(-0.93)- 43.6、1.06 - 8.17、6.20 - 44.0和5.97 - 97.4范围内测定。发现RBEP×明胶和RBEP×蔗糖之间的相互作用对颜色参数有影响。总酚含量(TPC)值和抗氧化活性抑制值(AA,%抑制)分别在25.6至257.4 mg GAE/kg和0.00 - 49.8%范围内。通过将质地特性和稳定性行为作为响应因素确定的最佳组合物,显示蔗糖、明胶溶液和RBEP的浓度分别为34.53 g/100 g、18.33 g/100 g和0.44 g/100 g。该研究首次考察了RBEP浓度对软糖质量参数的影响以及与配方中其他成分的相互作用。研究结果将提高糖果行业对色素使用的认识,并有助于开发新产品。
