Abstract

Abstract:

Hogwash oil is mainly refined from restaurant waste oil, waste frying oil and waste animal fat. Its composition is
complex. Consumption of hogwash oil poses potentially serious health risks to consumers due to the presence of many toxic
compounds. As hogwash oil incidents occurred frequently in recent years, crackdown on illegal hogwash oil incidents has
been one of the key points of food safety regulation. Rapid and accurate detection techniques are of critical importance for
the identification of hogwash oil. The origin and harm of hogwash oil are briefly illustrated in this article, and the analytical
techniques used in the last 5 years to detect hogwash oil are deeply analyzed, including spectroscopy, chromatography,
electronic nose, electrochemical analysis, immunology and molecular biology techniques. In this review, the emphasis is
put on some emerging analytical techniques. The current status and future prospects of the detection techniques for hogwash
oil are discussed. In addition, the present situation of the industrial utilization of hogwash oil is summarized and evaluated,
aiming to provide references and ideas for reasonably addressing the problem of illegal hogwash oil.

Key words: hogwash oil, identification, detection technique, utilization
