Evaluation reveals cryogenic treatment reduces antioxidants in yellow passion fruit pulp, indicating selective preservation of vitamin C.

Key Points

The research aims to assess how cryogenic ultra-freezing affects the antioxidant profile of yellow passion fruit pulp.
Compared fresh pulp samples with those subjected to cryogenic ultra-freezing using liquid nitrogen.
Measured antioxidant profile parameters including total phenolic content and total flavonoid content.
Conducted analyses in technical triplicate to ensure statistical reliability.
Antioxidant capacity decreased by 23.6% following ultra-freezing.
Total phenolic content decreased by 40.3%, reaching 123.67 mg GAE/100 g.
Total flavonoid content decreased by 35.7%, reaching 1.08 mg RE/L.
Ascorbic acid content remained stable, measuring between 38.08 and 38.43 mg/100 g.
