Flaxseed gum (FG) is a by-product of flax (Linum usitatissimum L.) meal production that is useful as a food thickener, emulsifier, and foaming agent. FG is typically recovered by hot-water extraction from flaxseed hull or whole seed. However, FG includes complex polymer structures that contain bioactive compounds. Therefore, extraction temperature can play an important role in determining its functional properties, solution appearance, and solution stability during storage. These characteristics of FG, including FG quality, determine its commercial value and utility. In this study, FG solution functional properties and storage stability were investigated for solutions prepared at 70 and 98 °C. Solutions of FG prepared at 98 °C had lower initial viscosity than solutions extracted at 70 °C; though the viscosity of these solutions was more stable during storage. Solutions prepared by extraction at both tested temperatures exhibited similar tolerance to 0.1 mol/L salt addition and freeze-thaw cycles. Moreover, the higher extraction temperature produced a FG solution with superior foaming and emulsification properties, and these properties were more stable with storage. Foams and emulsions produced from FG extracted at higher temperatures also had better stability. FG extracted at 98 °C displayed improved stability and consistent viscosity, foamability, and emulsification properties in comparison to solutions prepared at 70 °C. Therefore, the FG solution extracted at 98 °C had more stable properties and, potentially, higher commercial value. This result indicates that FG performance as a commercial food additive can influence food product quality.

亚麻籽胶溶液的功能特性。

亚麻籽胶(FG)是亚麻(Linum usitatissimumL.)用作食品增稠剂,乳化剂和发泡剂的粗粉生产。FG通常通过热水提取从亚麻籽壳或整个种子中回收。但是,FG包含含有生物活性化合物的复杂聚合物结构。因此,萃取温度在决定其功能特性,溶液外观和储存过程中的溶液稳定性方面可以发挥重要作用。FG的这些特征,包括FG的质量,决定了其商业价值和实用性。在这项研究中,对于在70和98°C下制备的溶液,研究了FG溶液的功能特性和储存稳定性。在98°C下制备的FG溶液的初始粘度低于在70°C下萃取的溶液。尽管这些溶液的粘度在储存过程中更稳定。在两个测试温度下通过萃取制备的溶液均表现出对0.1 mol / L盐添加和冻融循环相似的耐受性。此外,较高的萃取温度产生了具有优异的起泡和乳化性能的FG溶液,并且这些性能在储存时更稳定。由高温提取的FG生产的泡沫和乳液也具有更好的稳定性。与在70°C下制备的溶液相比,在98°C下提取的FG表现出更高的稳定性和一致的粘度,发泡性和乳化特性。因此,在98°C下萃取的FG溶液具有更稳定的性能,并可能具有更高的商业价值。该结果表明FG作为商业食品添加剂的性能会影响食品质量。1 mol / L的盐添加和冻融循环。而且,较高的提取温度产生了具有优异的起泡和乳化性能的FG溶液,并且这些性能在储存时更稳定。由高温提取的FG生产的泡沫和乳液也具有更好的稳定性。与在70°C下制备的溶液相比,在98°C下提取的FG表现出更高的稳定性和一致的粘度,发泡性和乳化特性。因此,在98°C下萃取的FG溶液具有更稳定的性能,并可能具有更高的商业价值。该结果表明FG作为商业食品添加剂的性能会影响食品质量。1 mol / L的盐添加和冻融循环。而且,较高的提取温度产生了具有优异的起泡和乳化性能的FG溶液,并且这些性能在储存时更稳定。由高温提取的FG生产的泡沫和乳液也具有更好的稳定性。与在70°C下制备的溶液相比,在98°C下提取的FG表现出更高的稳定性和一致的粘度,发泡性和乳化特性。因此,在98°C下萃取的FG溶液具有更稳定的性能,并可能具有更高的商业价值。该结果表明FG作为商业食品添加剂的性能会影响食品质量。这些特性在储存时更加稳定。由高温提取的FG生产的泡沫和乳液也具有更好的稳定性。与在70°C下制备的溶液相比,在98°C下提取的FG表现出更高的稳定性和一致的粘度,发泡性和乳化特性。因此,在98°C下萃取的FG溶液具有更稳定的性能,并可能具有更高的商业价值。该结果表明FG作为商业食品添加剂的性能会影响食品质量。这些特性在储存时更加稳定。由高温提取的FG生产的泡沫和乳液也具有更好的稳定性。与在70°C下制备的溶液相比,在98°C下提取的FG表现出更高的稳定性和一致的粘度,发泡性和乳化特性。因此,在98°C下萃取的FG溶液具有更稳定的性能,并可能具有更高的商业价值。该结果表明FG作为商业食品添加剂的性能会影响食品质量。在98°C下萃取的FG溶液具有更稳定的性能,并可能具有更高的商业价值。该结果表明FG作为商业食品添加剂的性能会影响食品质量。在98°C下萃取的FG溶液具有更稳定的性能,并可能具有更高的商业价值。该结果表明FG作为商业食品添加剂的性能会影响食品质量。
