Starch gelatinization - Wikipedia
Starch gelatinization is a process of breaking down of intermolecular bonds of starch molecules in the presence of water and heat, allowing the hydrogen bonding sites (the hydroxyl hydrogen and oxygen) to engage more water. This irreversibly dissolves …
糊化 - 百度百科
糊化(Gelatinization),一般是指淀粉的糊化(α-化),是将 淀粉 混合于水中并加热,达到一定温度后,则淀粉粒 溶胀 、 崩溃,形成 粘稠 均匀 的透明糊溶液。 淀粉糊化本质是水进入微晶束,折散淀粉分子间的 缔合 状态,使淀粉分子失去原有的取向排列,而变为混乱状态,即淀粉粒中有序态(晶态)及无序态(非晶态)的分子间的氢键断开,分散在水中成为胶体溶液。 淀粉乳受热后,在一定温度范围内, 淀粉粒 开始破坏, 晶体结构 消失,体积膨大, 粘度 急剧上升,呈 …
Starch Gelatinization - Biology Reader
Starch gelatinization is a phenomenon in which the starch granules primarily absorb water, swell and eventually burst out to form a gel in the presence of water and heat. Gelatinization of starch is a method that requires starch (any sources like cornstarch, rice flour etc.) as …

Gelatinisation is complete when the liquid reaches around 96C. As the mixture cools it thickens even more, setting and firming. It turns into a gel at about 38°C. The effect of sugars on the thickening of the sauce. Other ingredients contained within a sauce can slow down the rate that the water is absorbed. For example, a sauce containing sugar.
1.5: Gelatinization - Chemistry LibreTexts
2022年5月10日 · Gelatin is a water-soluble protein extracted from animal tissue and used as a gelling agent, a thickener, an emulsifier, a whipping agent, a stabilizer, and a substance that imparts a smooth mouth feel to foods. It is thermo-reversible, meaning the setting properties or action can be reversed by heating.
Starch Gelatinization - an overview | ScienceDirect Topics
Starch gelatinization is an endothermic process that corresponds to the loss of starch crystallinity in the starch granules under particular heat and moisture conditions. During thermal treatment, starch granules imbibe water and swell considerably, resulting in …
Gelatinization - an overview | ScienceDirect Topics
Gelatinization is one of the most important transitions that starch undergoes during processing and that result in a notable change in its properties. It occurs when starch is heated in the presence of water. The extent of the gelatinization transition is influenced by the rate of heating, temperature, and moisture [4, 5•, 6].
An Insight into the Gelatinization Properties Influencing the …
2022年2月3日 · Gelatinization is an important phenomenon when it comes to the cooking properties, texture, and palatability of starch-based food products. Starch gelatinization disrupts the molecular orderliness within the granule and results in granular swelling, crystallite melting, loss of birefringence, increase in viscosity, and solubilization.
Gelatinization - an overview | ScienceDirect Topics
Gelatinization (also known as pasting) is the process whereby the starch granules swell and eventually disappear, the crystalline regions are progressively ‘melted’ and the starch molecules are unfolded and hydrated, resulting in the formation of a continuous viscous paste. You might find these chapters and articles relevant to this topic.
Starch Gelatinization and Modification | SpringerLink
Gelatinization is an endothermic reaction involving starch, moisture, and heat. The gelatinization properties of starches such as gelatinization temperature, change in enthalpy, and melting of amylose–lipid complex vary substantially depending on …
