摘要
目前市面上食品级油溶性色素产品多出现颜色不均一、体系分层的现象。本研究以表观黏度为指标,构建食品级油溶色素(胭脂红铝色淀、柠檬黄铝色淀和亮蓝铝色淀)的稳定工艺,并通过单因素试验结果,结合观察实验样品体系液面分离高度选择适当条件进行正交试验,优化配方。研究结果表明,当白砂糖添加量为4.00%,奶粉添加量为0.83%,可可脂添加量为5.20%,大豆油添加量为66.20%,色淀添加量为22.10%,大豆卵磷脂添加量为0.28%,聚甘油蓖麻醇酸酯添加量为0.46%和甘油添加量为1.00%时,3种食品级油溶性色素体系表观黏度最高,稳定性最佳。最佳配方验证结果显示,3种食品级色素体系流变学特性均符合Herschel-Bulkley模型,呈现屈服-假塑性流体特性。本研究结果充分显示了食品级油溶性色素的可行性,为食品级油溶性色素市场发展提供更多理论支持。
Many food-grade oil-soluble pigments on the market often exhibit issues such as uneven color distribution and phase separation.In this study,the apparent viscosity was taken as the index to establish the stability process of food-grade oil-soluble pigments(carmine aluminum lake,tartrazine aluminum lake and brilliant blue aluminum lake),and the orthogonal test was carried out by selecting appropriate conditions based on the single factor test results and observing the liquid level separation height of the experimental sample system to optimize the formula.The optimized formula was as follows:4.00%sugar,0.83%milk powder,5.20%cocoa butter,66.20%soybean oil,22.10%lake pigment,0.28%soybean lecithin,0.46%PGPR,and 1.00%glycerin.This formulation resulted in the highest apparent viscosity and optimal stability for all three food-grade oil-soluble pigment systems.Verification of the optimal formulation demonstrated that the rheological properties of the three pigment systems aligned with the Herschel-Bulkley model,exhibiting yield-pseudoplastic fluid characteristics.This study confirmed the feasibility of producing stable food-grade oil-soluble pigments and it provides a theoretical foundation for the development of the food-grade oil-soluble colorant market.
