（1）小磨香油用水代法生产，芝麻酱，此法主要是利用油料中非油成分对油和水的亲和力差异，并利用油水比重不同而将油脂与其它物质分离。对人体健康不利的重金属化合物因比重较大而沉淀酱渣中，从而避免了重金属对人体的危害。

(1) Xiaomo sesame oil is produced by water instead of sesame paste. This method mainly uses the affinity difference of non oil components in oil to oil and water, and uses the different proportion of oil and water to separate oil from other substances. Heavy metal compounds, which are harmful to human health, precipitate into sauce dregs because of their large proportion, so as to avoid the harm of heavy metals to human body.

（2）机榨油只是用物理的压榨方法把油强行挤出，所以芝麻中的重金属化合物都混入油中，芝麻酱机，形成潜在隐患。

(2) The machine press oil only uses the physical press method to force out the oil, so the heavy metal compounds in sesame are mixed into the oil, forming a potential hazard.

（3）部分机榨油由于压榨取油不彻 底，厂家便采用化学溶剂浸出法取残油，而化学溶剂又不净，则导致化学溶剂残留。食用后危害人体健康，而在标准中机制香油是不允许溶剂残留检出的

(3) Due to the incompleteness of extracting oil from some machine pressed oil, the manufacturers use the chemical solvent leaching method to extract the residual oil, and the chemical solvent is not cleaned up, which leads to the residual chemical solvent. It is harmful to human health after eating, but in the national standard, the residual solvent is not allowed to be detected in machine-made sesame oil

一般情况下为保留香油的香味，不会对这些浸出油再进行脱溶和精炼，但是这部分厂家也深知浸出工艺对于香油风味的负面影响，所以在上市时，采取了变通办法：用小磨香油与机榨浸出的香油进行勾兑，用以减轻浸出油的危害，并以此提高机榨、浸出香油的风味，推向市场后就成了一般消费者难以区别的“小磨香油”，实际上是一种对消费者的欺骗行为，限于香油这一产品的特殊性，在食用时不经熟锅，而是直接倒入菜中食用（即香油是一种生食油），这样如掺入有溶剂残留的浸出油，就会影响消费者的身体健康。

In general, in order to retain the flavor of sesame oil, these extracted oils will not be desolved and refined again. However, these manufacturers are also well aware of the negative impact of the extraction process on the flavor of sesame oil, so they adopted an alternative method when they went on the market: blending the small mill sesame oil with the machine extracted sesame oil, so as to reduce the harm of the extracted oil and improve the flavor of the machine pressed and extracted sesame oil, After being put into the market, it has become a kind of "small grinding sesame oil" which is difficult for ordinary consumers to distinguish. In fact, it is a kind of deceptive behavior to consumers. Due to the particularity of sesame oil, it can be directly poured into vegetables (that is, sesame oil is a kind of raw oil) without cooking pot. If it is mixed with solvent residue, it will affect the health of consumers.

芝麻油根据香味特点分为两类：一是香油，具有浓郁或显著的芝麻油香味。芝麻中的有成分经高温炒料工艺处理后，生成具有特殊香味的物质，致使芝麻油具有独特的香味，有别于其他各种食用植物油，故称香油。

Sesame oil can be divided into two types according to the flavor characteristics: one is sesame oil, which has strong or significant sesame oil flavor. Sesame oil has a unique flavor, which is different from other edible vegetable oils, so it is called sesame oil.

香油按加工工艺分为小磨香油和机制香油两种。二是普通芝麻油，香味清淡。用一般的压榨法、浸出法或其他方法加工制取。由于芝麻油中含有一定数量的维生素E和芝麻油中特有的芝麻酚芝麻酚林等物质，这些物质的抗氧化能力极强，因此芝麻油比其他植物油更宜储存。

According to the processing technology, sesame oil can be divided into two kinds: small mill sesame oil and machine-made sesame oil. The second is common sesame oil with light fragrance. It is made by pressing, leaching or other methods. Sesame oil contains a certain amount of vitamin E, sesamol, sesamolin and other substances, which have strong antioxidant capacity. Therefore, sesame oil is more suitable for storage than other vegetable oils.
