Lecithin is constituted of a glycerophospholipid mixture and is abundantly used as an emulsifying agent in various food applications including chocolate production. However, overconsumption of lecithin may create an adverse effect on human health. Thus, this study aims to replace the lecithin with plant-based gums. Different ratios of guar and arabic gum (25%-75%) and their blend (25%-75%) were employed as partial replacement of lecithin. Milk chocolate prepared using 40% guar gum (60GGL [guar gum, lecithin]), 25% arabic gum (75AGL [arabic gum, lecithin]), and a blend of 15 arabic gum and 10 guar gum (65AGGL [arabic gum, guar gum, lecithin]) showed similar rheological behavior as compared to control chocolate (100% lecithin). The fat content of 65AGGL (37.85%) was significantly lower than that of the control sample (43.37%). Rheological behavior exhibited shear-thinning behavior and samples (60GGL-75GGL-80GGL, 65AGL-75AGL, and 65AGGL-75AGGL) showed similar rheological properties as compared to control. The chocolate samples (60GGL and 65AGGL) showed significantly ( < .05) higher hardness values (86.01 and 83.55 N) than the control (79.95 N). As well, gum-added chocolates exhibited higher thermal stability up to 660°C as compared to the control sample. The Fourier transform infrared spectroscopy (FTIR) analysis revealed predominant β-(1 → 4) and β-(1 → 6) glycosidic linkages of the gums and lecithin. Sensory evaluation revealed a comparable score of gum-added milk chocolate in comparison to control samples in terms of taste, texture, color, and overall acceptance. Thus, plant exudate gums could be an excellent alternative to lecithin in milk chocolate, which can enhance the textural properties and shelf life.
卵磷脂由甘油磷脂混合物构成,在包括巧克力生产在内的各种食品应用中被大量用作乳化剂。然而,过量食用卵磷脂可能会对人体健康产生不利影响。因此,本研究旨在用植物基胶替代卵磷脂。使用不同比例的瓜尔胶和阿拉伯胶(25%-75%)及其混合物(25%-75%)作为卵磷脂的部分替代品。使用40%瓜尔胶(60GGL[瓜尔胶,卵磷脂])、25%阿拉伯胶(75AGL[阿拉伯胶,卵磷脂])以及15%阿拉伯胶和10%瓜尔胶的混合物(65AGGL[阿拉伯胶,瓜尔胶,卵磷脂])制备的牛奶巧克力与对照巧克力(100%卵磷脂)相比,表现出相似的流变行为。65AGGL的脂肪含量(37.85%)显著低于对照样品(43.37%)。流变行为表现出剪切变稀行为,样品(60GGL - 75GGL - 80GGL、65AGL - 75AGL和65AGGL - 75AGGL)与对照相比表现出相似的流变特性。巧克力样品(60GGL和65AGGL)的硬度值(86.01和83.55 N)显著高于对照(79.95 N)(P < 0.05)。此外,与对照样品相比,添加胶的巧克力在高达660°C时表现出更高的热稳定性。傅里叶变换红外光谱(FTIR)分析揭示了胶和卵磷脂中主要的β-(1→4)和β-(1→6)糖苷键。感官评价显示,添加胶的牛奶巧克力在味道、质地、颜色和总体接受度方面与对照样品得分相当。因此,植物渗出胶可以成为牛奶巧克力中卵磷脂的极佳替代品,能够增强质地特性和保质期。
