The guava is one of the tropical fruits with the highest nutritional value, rich in vitamins C and pro-vitamin A, possessing excellent acceptance of in natura consumption as well as great industrial applicability. Vitamin C, carotenoids, anthocyanins and phenolics are considered compounds with antioxidant activity and the consumption of these substances in the daily diet can produce an effective protective action against the oxidative processes that occur naturally in the organism. This work aimed to study the stability of the vitamin C, carotenoids, anthocyanins and total phenolics of unsweetened guava tropical juice obtained by hot fill and aseptic processes for 250 days of storage at room temperature (28 ± 2 ºC). The results showed that the total carotenoids and total phenolics did not vary during the storage time, while the vitamin C decreased.
