（1）小磨香油用水代法生產，芝麻醬，此法主要是利用油料中非油成分對油和水的親和力差異，并利用油水比重不同而將油脂與其它物質分離。對人體健康不利的重金屬化合物因比重較大而沉淀醬渣中，從而避免了重金屬對人體的危害。

(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）機榨油只是用物理的壓榨方法把油強行擠出，所以芝麻中的重金屬化合物都混入油中，芝麻醬機，形成潛在隱患。

(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）部分機榨油由于壓榨取油不徹 底，廠家便采用化學溶劑浸出法取殘油，而化學溶劑又不凈，則導致化學溶劑殘留。食用后危害人體健康，而在標準中機制香油是不允許溶劑殘留檢出的

(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

一般情況下為保留香油的香味，不會對這些浸出油再進行脫溶和精煉，但是這部分廠家也深知浸出工藝對于香油風味的負面影響，所以在上市時，采取了變通辦法：用小磨香油與機榨浸出的香油進行勾兌，用以減輕浸出油的危害，并以此提高機榨、浸出香油的風味，推向市場后就成了一般消費者難以區別的“小磨香油”，實際上是一種對消費者的欺騙行為，限于香油這一產品的特殊性，在食用時不經熟鍋，而是直接倒入菜中食用（即香油是一種生食油），這樣如摻入有溶劑殘留的浸出油，就會影響消費者的身體健康。

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.

芝麻油根據香味特點分為兩類：一是香油，具有濃郁或顯著的芝麻油香味。芝麻中的有成分經高溫炒料工藝處理后，生成具有特殊香味的物質，致使芝麻油具有獨特的香味，有別于其他各種食用植物油，故稱香油。

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.

香油按加工工藝分為小磨香油和機制香油兩種。二是普通芝麻油，香味清淡。用一般的壓榨法、浸出法或其他方法加工制取。由于芝麻油中含有一定數量的維生素E和芝麻油中特有的芝麻酚芝麻酚林等物質，這些物質的抗氧化能力極強，因此芝麻油比其他植物油更宜儲存。

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.
