A review of the occurrence, metabolites and health risks of butylated hydroxyanisole (BHA)

Abstract: Butylated hydroxyanisole (BHA) is mainly used as a food additive due to its antioxidant properties, which prevent or delay oxidation reactions and extend the storage life of products. The widespread use of BHA has led to its extensive presence in various environmental matrices and human tissues. Food intake is the main route of human exposure to BHA. Under different conditions, BHA can produce different metabolites, with tert‐butyl hydroquinone (TBHQ) being one of the major products. Several studies have shown… Show more

“…However, consumption of the latter three artificial antioxidants is associated with negative health effects. BHA has been implicated in thyroid damage, metabolic and growth disorders, neurotoxicity and carcinogenesis [29]. BHT is said to have toxic effects on motor and neurobehavioral activity, as well as implications for histopathological changes in the brain, heart and lungs [30].…”

“…Lipid oxidation is responsible for the development of unpleasant flavors and odors in food, making them unfit for consumption [1]. To extend the shelf life of food products, manufacturers often turn to synthetic phenolic antioxidants (SPAs), such as butylated hydroxyanisole (BHA), one of the main additives used in the food industry [2,3]. Commercially available BHA usually consists of two isomers: 10% 2-tert-butyl-4-hydroxyanisole (2-BHA) and 90% 3-tert-butyl-4-hydroxyanisole .…”

“…Commonly, synthetic antioxidants, such as butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), and tert-butyl hydroquinone (TBHQ), are added to edible oils to increase their shelf life. Recent reports indicate these synthetic antioxidants may cause adverse side effects to human health [Mika et al, 2023;Zhang et al, 2023]. Consequently, there is significant interest in enriching oils with natural antioxidants, such as lycopene, tocopherols, polyphenols, to hinder lipid oxidation [Bodoira et al, 2017;Omer et al, 2014;Xie et al, 2018;Zahran & Najafi, 2020].…”
