食品科学食品科学食品科学
园艺科学园艺科学
植物生理学植物生理学

背景情况:

在低温储存期间,水果的羊毛性显著降低了桃子的质量.
培凝的形成是桃子中羊毛性的主要原因.
了解凝的机制对于质量保存至关重要.

研究的目的:

在低温储存期间,系统地分析桃子的质地,水分分布,细胞壁微观结构和桃子中的pectin凝形成.
研究不同储存温度 (5°C与10°C) 对这些参数的影响.
阐明素特性在羊毛发育中的作用.

主要方法:

低场核磁共振 (LF-NMR) 用于水与pectin的相互作用.
风湿学分析以评估纹理和凝过渡.
细胞壁微观结构和pectin组成的分析 (阿拉比诺斯,银酸,化程度).

主要成果:

与10°C相比,储存在5°C的桃子显示出更高的性,膜透性和水结合能力.
在较低的温度下观察到细胞壁加厚和可提取果汁减少.
LF-NMR表明增强了水与pectin的相互作用,而rheology显示在几周内过渡到固体/凝状态.

Fruit Development, Structure, and Function

Fruit Development, Structure, and Function

Fruits form from a mature flower ovary. As seeds develop from the ovules contained within, the ovary wall undergoes a series of complex changes to form fruit. In some fruits, such as soybeans, the ovary wall dries; in other fruits, such as grapes, it remains fleshy. In some cases, organs other than the ovary contribute to fruit formation; such fruits are called accessory fruits.

Drying Shrinkage

Drying Shrinkage

When hardened concrete is exposed to air with a relative humidity of less than 100 percent, it begins to lose the free water within its capillaries. As this water evaporates, the water initially adsorbed onto the calcium silicate hydrates migrates towards these now empty spaces and eventually evaporates as well. Over time, as more water leaves, the volume of the concrete decreases, a phenomenon known as drying shrinkage.
A portion of this drying shrinkage can be reversed; if the concrete is...

Temperature Dependent Deformation

Temperature Dependent Deformation

In a nonhomogeneous rod made up of steel and brass, restrained at both ends and subjected to a temperature change, several steps are involved in calculating the stress and compressive load. Due to the problem's static indeterminacy, one end support is disconnected, allowing the rod to experience the temperature change freely. Next, an unknown force is applied at the free end, triggering deformations in the rod's steel and brass portions. These deformations are then calculated and added...
