Quinoa leaves as a source of soluble proteins: Extraction and proteomic characterization from four different varieties of Chenopodium quinoa.

This work assessed four varieties of quinoa leaves, two grown in Ireland and two in Chile, as endogenous sources of soluble proteins. The four leaf protein extracts, obtained using mild extraction conditions, had different nutrient compositions, with protein contents ranging from 53 ± 2 to 63 ± 2 %. The protein extract from variety quinoa Zeno (Ireland) presented the lowest content of chlorophyll, 0.

Recovery of Protein from Industrial Hemp Waste (, L.) Using High-Pressure Processing and Ultrasound Technologies.

Hemp seeds are currently used mainly for oil extraction, generating waste that could be potentially exploited further as a source of proteins and other bioactives. This study aims to valorise hemp waste (, L.) from previous oil extraction as a source of protein by analysing the effect of high-pressure processing (HPP) pre-treatments (0-600 MPa; 4-8 min) combined with conventional or ultrasound-assisted extraction (UAE) methods on protein recovery/purity, amino acid composition, and protein structure.
