Feasibility of using nanocellulosic fiber (NF) from lime residues as a stabilizer for oil-in-water emulsion was investigated. One-step process to simultaneously prepare an emulsion and NF is proposed. NF could spontaneously form by adding appropriately prepared fiber powder into the test emulsion viz. coconut milk, which was subsequently subject to homogenization and sterilization. Properties of the samples, that is, microstructure, rheological properties, emulsion stability, and color, after sterilization and after 8-week storage at 30 °C were determined. Sterilized samples exhibited pseudoplastic behavior. Samples containing higher NF concentrations exhibited higher viscosity; viscosity remained constant throughout the whole storage period. High emulsion stabilities (>97%) were observed for samples containing 0.4 to 0.8% (w/v) of NF. L* , C* , and h* of the samples were 79 to 80, 8 to 10, and 90, respectively. Three-dimensional network of NF (diameters < 50 nm) attached to fat globule surfaces formed during homogenization is postulated to help stabilize the emulsions. PRACTICAL APPLICATION: One-step process to simultaneously prepare oil-in-water emulsion as well as nanocellulosic fiber (NF) is proposed. Such a formed NF can serve as natural ingredient to stabilize the emulsion. The proposed procedures should be of great interest to an industry producing oil-in-water emulsions (for example, canned coconut milk) that is looking for a natural alternative to synthetic stabilizer.

使用和理解来自石灰（柑橘）残留物自发形成的纳米纤维素纤维在提高灭菌椰奶稳定性方面的作用

研究了使用石灰渣中的纳米纤维素纤维 (NF) 作为水包油乳液稳定剂的可行性。提出了同时制备乳液和 NF 的一步法。通过将适当制备的纤维粉末添加到测试乳液中，NF 可以自发形成。椰奶，随后进行均质和灭菌。测定灭菌后和在 30°C 下储存 8 周后样品的性质，即微观结构、流变学性质、乳液稳定性和颜色。灭菌样品表现出假塑性行为。含有较高 NF 浓度的样品表现出较高的粘度；粘度在整个储存期间保持恒定。对于含有 0.4 至 0.8% (w/v) NF 的样品，观察到高乳液稳定性 (>97%)。L* , C* , 样品的 h* 分别为 79 至 80、8 至 10 和 90。假设 NF 的三维网络（直径 < 50 nm）附着在均质过程中形成的脂肪球表面，以帮助稳定乳液。实际应用：提出了同时制备水包油乳液和纳米纤维素纤维 (NF) 的一步法。这种形成的NF可以作为稳定乳液的天然成分。对于正在寻找合成稳定剂的天然替代品的生产水包油乳液（例如罐装椰奶）的行业来说，拟议的程序应该引起极大的兴趣。50 nm) 附着在匀浆过程中形成的脂肪球表面被假定有助于稳定乳液。实际应用：提出了同时制备水包油乳液和纳米纤维素纤维 (NF) 的一步法。这种形成的NF可以作为稳定乳液的天然成分。对于正在寻找合成稳定剂的天然替代品的生产水包油乳液（例如罐装椰奶）的行业来说，拟议的程序应该引起极大的兴趣。50 nm) 附着在匀浆过程中形成的脂肪球表面被假定有助于稳定乳液。实际应用：提出了同时制备水包油乳液和纳米纤维素纤维 (NF) 的一步法。这种形成的NF可以作为稳定乳液的天然成分。对于正在寻找合成稳定剂的天然替代品的生产水包油乳液（例如罐装椰奶）的行业来说，拟议的程序应该引起极大的兴趣。
