Ultrasound-Assisted Extraction for the Recovery of Carotenoids from Guava's Pulp and Waste Powders.

In this work, lycopene- and β-carotene-rich extracts were obtained from guava's pulp and waste powders using maceration (ME), ultrasonic bath (BUAE, 25 °C for 30 min), and ultrasonic probe (PUAE, 25 °C for 5 min). Extracts were evaluated for total carotenoid content, antioxidant capacity, color, and lycopene and β-carotene content by HPLC-DAD. Bath-type ultrasound-assisted extraction (BUAE) was the best technique to obtain lycopene from guava pulp (135.

May the superfruit red guava and its processing waste be a potential ingredient in functional foods?

Guava (Psidium guajava L.), a popular fruit in tropical countries, can be consumed in natura or transformed into many products. Guava's processing waste (seed, peel, and pulp leftovers) can represent up to 30% of the fruit's volume.
