Special Issue Information

Dear Colleagues,

This Special Issue on the protein from plants and animals explores the latest research developments related to these dietary components' extraction, characterization, application, and enrichment. Proteins in the human diet from plants and animals are all broadly recognized as having health benefits (providing essential amino acids, satisfying metabolic requirements for amino acids and nitrogen, and maintaining an intestinal flora balance) and technological functionality, such as emulsification, foaming, and gelling, which gives food their appealing nutritional and texture/sensory attributes.

This Special Issue aims to showcase cutting-edge research on the enrichment of the nutritional and technological functionality of proteins from plants and animals, with a particular emphasis on improving physical, chemical, and/or biochemical treatments for the protein alone or in combination with other components. In addition, studies in which two or more plant/animal proteins are consumed together to provide essential amino acids, address structural barriers to improve bioaccessibility and bioavailability, or eliminate allergenicity are also strongly welcomed.

This Special Issue invites original research articles, reviews, and short communications highlighting recent advances in this rapidly evolving field.

The objective of this study was to investigate the umami characteristics of soy sauce using electronic tongue evaluation and amino acid composition and matrix-assisted laser desorption ionization–time of flight mass spectrometry (MALDI−TOF MS) analysis. The soy sauce peptides were isolated from soy sauce using XAD−16 macroporous resin combined with ethanol solution. The results showed that the soy sauce peptide fraction eluted by 60% ethanol (SS−60%) exhibited a prominent umami taste, and the umami scores were highly positively correlated with the amino acid nitrogen contents of soy sauces. The umami scores of SS−60% were significantly positively correlated with the contents of free amino acids. Especially, Phe showed the highest positive correlation with the umami scores. In addition, five characteristic ion peaks with m/z at 499, 561, 643, 649, and 855 were identified in the peptide mass fingerprinting. Therefore, this study provides new insights into the umami characteristics for the taste evaluation and reality identification of soy sauce. Full article
