However, the commonly used synthetic antioxidants such as
butylated hydroxyanisole (BHA) and butylated hydroxy toluene
(BHT) are restricted by legislative rules because they are suspected
to have some toxic effects and as possible carcinogens (Imaida et al.,
1983). Therefore, there has been a considerable interest by the
industry and a growing trend in consumer preferences for natural
antioxidants over synthetic compounds and elimination of synthetic
antioxidants in food applications has given more impetus to explore
natural source of antioxidants. Thus, antioxidants are of interest to
both food scientists and health professionals and there has been a
convergence of interest among researchers in these fields as the role
of antioxidants in the diet and their impact on human health has come
under attention. In the present study, the antioxidant activity of the
extracts of pineapple fruit was assayed through various in vitro
models. So far we know, this is the first report on antioxidant activity
of tropical pineapple fruit.
