油凝胶全替代型预拌粉对冰淇淋的品质提升研究

Improvement of Ice Cream Quality by Oleogel Full-replacement Premix Powder

  • 摘要: 为获得健康低脂的冰淇淋制品,采用中链甘油三酯(MCT)油凝胶全替代氢化棕榈仁油(HPKO),制备蜂蜡油凝胶基冰淇淋预拌粉(BW-P),考察其粉末性质及对冰淇淋品质特性的提升效果。结果表明,相较于商用预拌粉(C-P),BW-P和HPKO基冰淇淋预拌粉(HPKO-P)水分含量更高,流动性与溶解性较低。扫描电镜观察发现,BW-P和HPKO-P均呈球形。经复溶后,HPKO-P和BW-P乳液粒径主要分布于1~10 μm,而C-P乳液粒径较大(10~100 μm)。微流变学测定显示,BW-P复溶乳液的去相关时间较长,脂肪网络致密,与C-P相近。BW-P冰淇淋的膨胀率较低(45.3%),硬度较高(15.1 kPa),其外观色泽均匀、形状完整。该样品融化速率较慢,略有油腻感,其口腔摩擦学特性及电子舌评分与C-P接近,具备替代HPKO制备冰淇淋预拌粉的良好潜力。

     

    Abstract: To obtain healthy and low-fat ice cream products, beeswax oleogel-based ice cream premix (BW-P) was prepared by fully replacing hydrogenated palm kernel oil (HPKO) with medium-chain triglyceride (MCT) oleogel. The powder properties and the enhancing effect on ice cream quality characteristics were investigated. The results showed that compared with commercial premix (C-P), both BW-P and HPKO-based ice cream premix (HPKO-P) had higher moisture content, lower fluidity and solubility. Scanning electron microscopy observation revealed that both BW-P and HPKO-P exhibited a spherical morphology. After reconstitution, the emulsion particle sizes of HPKO-P and BW-P were mainly in the range of 1~10 μm, while that of C-P was larger (10~100 μm). Microrheological measurements indicated that the reconstituted emulsion of BW-P had a longer decorrelation time and a dense fat network, which was similar to C-P. The BW-P ice cream showed a lower overrun (45.3%) and higher hardness (15.1 kPa), with uniform appearance color and intact shape. This sample had a slow melting rate and a slight greasy feeling, and its oral tribological properties and electronic tongue scores were close to those of C-P, exhibiting good potential to replace HPKO in the preparation of ice cream premix powder.
