This work presents a review on the composition and extraction techniques for recovering phytochemicals from passion fruit by-products. The review approaches on the characteristics of each phytochemical and its benefits to human health. It was observed that the by-products of passion fruit contain a range of interesting substances, and for their recovery the application of environmentally friendly extraction techniques, such as supercritical fluid extraction (SFE) and pressurized liquid extraction (PLE), are suggested as single or sequential procedures. The future perspectives of this review encourage the application of these techniques to a complete recovery of passion fruit by-products.
