为了研究可食用植物组织的结构属性对餐后阶段细胞基质中细胞内物质释放的影响，以柑橘皮的外果皮层粉末为模型，研究了3种溶剂对细胞内物质的洗脱特性。结果表明，萃取液的吸收光谱随溶剂种类和分级粉末的平均粒径而变化。特别地，粒度对吸收光谱的影响表现为在每个波长处的吸收水平的差异，例如，平均粒径为711 μm的提取物在490 ~ 520 nm范围内的吸光度几乎是71 μm提取物的一半，尽管每个级分都是由相同的来源制备的。此外，显微镜观察表明，粉末中的破碎细胞的百分比随着平均粒径的增加而减少。这表明，基于细胞的植物组织的结构属性可能与细胞内物质的洗脱特性和基于植物的食物的餐后营养特性有关。
To examine the effect of structural attributes of edible plant tissues on the release of intracellular substances from cell matrices at the postprandial stage, a flavedo layer powder of citrus peel was used as a model of mechanically damaged plant tissue, and elution characteristics of intracellular substances with three types of solvent were investigated. The results showed that the absorbance spectra of extraction solutions were changed by the type of solvent and the average diameter of classified powders. In particular, the influence of particle size on the absorbance spectra appeared as differences in the absorbance level at each wavelength, e.g., the absorbance level of extractions with an average particle size of 711 μm was almost half of that of 71 μm at the range from 490 nm to 520 nm, although each fraction was made from the same source. Additionally, the microscopic observation showed that the percentage of disrupted cells in powders decreased with the average particle size increased. This suggested that the structural attributes of cell-based plant tissue could be linked to the elution properties of intracellular materials and the postprandial nutritional properties of plant-based foods.
