observed a higher β-carotene content (4060 μg/100 g) in conventionally grown acerola harvested during the rainy season and treated with chemical fertilizers 3 months before harvest. According to, soil fertilisation is one of the factors that affects the biosynthesis of carotenoids in fruits. This fact probaaly contributed to the higher β-carotene content observed in conventionally grown acerola fruits in this study.
