About This Topic

Large volumes of agri-food waste and by-products are a challenging field of research of great importance in the local and international economy. According to FAO, about a third of all food produced worldwide for human consumption is lost or wasted. On many occasions, the waste is stored or, in the best case, given a stabilization treatment, leading to its degradation or residual use. These residuals contain proteins and other essential nutrients with potentially bioactive properties, eligible for recycling and upgrading for higher-value products. Aiming to explore these concepts, this Special Issue will focus on the characterization, recovery and valorization of protein concentrates from the agri-food industry in order to transform these in resource for production of energy and new products, being welcomed original research reports, review articles, communications and perspectives in all areas pertinent to this topic. All accepted papers will be published totally free of charge.

Open Access Research Article

Meat Waste Valorization through Protein Hydrolysis using Different Types of Proteases

Received: 12 May 2021;  Published: 08 November 2021;  doi: 10.21926/rpm.2104045


Five different commercial proteases (Alcalase 2.4L, Flavourzyme 1000L, Neutrase, Protamex, and PTN) were evaluated for the simultaneous recovery of protein and lipids through hydrolysis. The hydrolysis reaction was monitored using the pH-stat procedure, in which samples were collected after 240 min of hydrolysis using each enz [...]

Production of Fermentable Sugars from Cassava Stem using Hybrid Pretreatment Technology

Received: 29 April 2021;  Published: 14 September 2021;  doi: 10.21926/rpm.2103037


One of the crucial steps in the enzymatic hydrolysis of biomass is pretreatment. We investigated the applicability of a hybrid pretreatment method, This involved acid treatment followed by alkali before the production of fermentable sugars from cassava stem. The substrate was initially treated with acid (1% oxalic acid at 100 [...]

Use of α-Lactalbumin [α-La] from Whey as a Vehicle for Bioactive Compounds in Food Technology and Pharmaceutics: A Review

Received: 26 April 2021;  Published: 22 June 2021;  doi: 10.21926/rpm.2102027


Whey protein is a byproduct of cheese, casein, and Greek yogurt produced in Europe, North America, and Australasia. It is a substantial source of functional proteins and peptides for the worldwide food industry. α-Lactalbumin (α-La) is a globular protein that can be isolated from WPI (whey protein isolate [...]

Potential of Wastewater Valorization after Wet Extraction of Proteins from Faba Bean and Pea Flours

Received: 02 December 2020;  Published: 21 April 2021;  doi: 10.21926/rpm.2102013


This study aimed at the characterization of wastewater fractions obtained after the wet extraction of proteins from legumes. The suitability of wastewater fractions for the potential recovery of high value-added compounds was also examined and as a consequence, the prevention of the environmental impact of these wastes. Similarly to industrial [...]
