甘油（丙三醇）在正常情况下是一种无色、无臭、味甜，外观呈澄明黏稠液态的有机物。然而在下列情况下，甘油的气味、色泽以及口感会发生变化，下面小编带您一起了解下：

Glycerin (glycerol) is a colorless, odorless, sweet organic substance with a clear, viscous liquid appearance under normal conditions. However, under the following circumstances, the smell, color and taste of glycerol will change. Here is a brief introduction to let you know:

只要使用高质量高的原料，恰当储存粗甘油，避免长时间高温，大部分气味和色泽问题都可可以避免。粗甘油中的杂质，尤其是非甘油有机物（MONG)，会影响蒸馏甘油的质量和产量。如果非甘油有机物含量很高（3%-5%)，成品会存在气味、口感和回色问题。非甘油有机物中存在的三亚甲基乙二醇会影响甘油的色泽，同时引起储存中的问题。

Most odor and color problems can be avoided as long as high-quality raw materials are used, crude glycerol is properly stored, and long-term high temperature is avoided. Impurities in crude glycerol, especially non-glycerol organics (MONG), will affect the quality and output of distilled glycerol. If the content of non-glycerol organic matter is very high (3% - 5%), the finished product will have odor, taste and color problems. The presence of trimethylene glycol in non-glycerol organic matter will affect the color of glycerol and cause problems in storage.

沸点接近的杂质和大部分气味物质可以用一个脱臭塔或脱气装置除去，该设备安装在蒸馏柱之后，在高真空下用直接蒸汽（或：“喷射”蒸汽）进行操作。剩余的色素物质通过活性炭吸附除去。

Impurities with close boiling points and most odor substances can be removed by a deodorizer or degassing device, which is installed after the distillation column and operated with direct steam (or "jet" steam) under high vacuum. The remaining pigment substances are removed by adsorption of activated carbon.

在有铁离子、铁盐。酸或中性盐存在时，会产生丙烯醛。丙烯醛的气味和特别，很低含量时人的鼻子就可以嗅出。

There are iron ions and iron salts. In the presence of acid or neutral salt, acrolein will be produced. The smell of acrolein is very special. People can smell it when the content is very low.

残留在各种加工设备（尤其是在炭吸附柱）中的甘油会编制，并生产很难去除的气味物质。因此，工艺设备在停工后须清洗，炭吸附柱要用空气吹干并水洗。新鲜的活性炭有时也含有产生气味的杂质。这些炭可以用蒸馏的甘油洗涤，这些甘油可以通过重整理回收或作为低档产品销售。

The glycerol remaining in various processing equipment (especially in carbon adsorption column) will be prepared and produce odor substances that are difficult to remove. Therefore, the process equipment shall be cleaned after shutdown, and the carbon adsorption column shall be dried with air and washed with water. Fresh activated carbon sometimes contains impurities that produce odor. These carbons can be washed with distilled glycerin, which can be recycled through rearrangement or sold as low-grade products.

此外甘油对皮肤没有害，甘油的作用是吸水保湿，不论从成分还是功效上都不会对皮肤造成伤害，即使长期使用也不会发生副作用。只是要注意甘油的使用方法和注意事项，如果没有使用得当，可能会让皮肤变干。只要合理的运用，可以放心的使用！您可以来我们网站http://www.jinhao360.com咨询更多相关事项！

In addition, glycerin is harmless to the skin. Its function is to absorb water and moisturize. It will not cause damage to the skin in terms of composition or efficacy, and will not have side effects even if it is used for a long time. Just pay attention to the use method and precautions of glycerin. If it is not used properly, it may dry the skin. As long as it is used reasonably, it can be used safely!
