Special Issue Information

In the last years, foodomics techniques saw an exceptional emergence owing to the implementation, progression, and development of new tools and technologies. Foodomics rapidly evolved as an innovative scientific discipline able to provide a comprehensive evaluation of food and nutrition through the use of modern omics techniques, including proteomics, peptidomics, and metabolomics. Foodomics techniques provide appropriate technical solutions for a variety of food science applications, finding application in different areas: food authentication and profiling, food quality and safety, food processing and digestion, identification of bioactive compounds, nutrition, and human health. Proteomics has been widely used to evaluate food authenticity and adulteration, and peptidomics has been essential in the study of new bioactive peptides generated by food processing (i.e., fermentation and cooking) and digestion. Once released, these small motifs, originally encrypted in the parent proteins, may exert several biological activities (anti-hypertensive, immunomodulatory, anti-diabetic, anti-microbial, etc.). Phenolic compounds are well-known and thoroughly studied molecules that are widespread in the plant kingdom and vegetable foods. They are able to exert several beneficial effects on human health (anti-carcinogenic, anti-atherogenic, anti-inflammatory, and vasodilatory activities). In this sense, several works have underlined how a metabolomic approach is pivotal to understanding the mechanisms of action of these bioactive compounds both in vitro and in vivo. This Special Issue attempts to collect research and review papers focusing on all the possible applications of foodomics techniques (proteomics, peptidomics, and metabolomics) in food science and nutrition. Moreover, papers addressed to the field of bioactive compounds (e.g., bioactive peptides and phenolic compounds) are welcomed, with a special emphasis on the connection between bioactive compounds and human health.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Biology is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Mastitis is the most common infection of dairy goats impairing milk production and quality, which is usually recognized by mammary gland visual inspection and palpation. Subclinical forms of the disease are also widely represented, which lack the typical signs of the clinical ones but are still associated with reduced production and safety for human consumption of milk, generally presenting a high bacterial count. In order to obtain novel analytical tools for rapid and non-invasive diagnosis of mastitis in goats, we analyzed milk samples from healthy, subclinical and clinical mastitic animals with a MALDI-TOF-MS-based peptidomic platform, generating disease group-specific spectral profiles whose signal intensity and mass values were analyzed by statistics. Peculiar spectral signatures of mastitis with respect to the control were identified, while no significant spectral differences were observed between clinical and subclinical milk samples. Discriminant signals were assigned to specific peptides through nanoLC-ESI-Q-Orbitrap-MS/MS experiments. Some of these molecules were predicted to have an antimicrobial activity based on their strong similarity with homolog bioactive compounds from other mammals. Through the definition of a panel of peptide biomarkers, this study provides a very rapid and low-cost method to routinely detect mastitic milk samples even though no evident clinical signs in the mammary gland are observed.

As the apparent incidence of tree nut allergies rises, the development of MS methods that accurately identify tree nuts in food is critical. However, analyses are limited by few available tree nut protein sequences. We assess the utility of translated genomic and transcriptomic data for library construction with Juglans regia, walnut, as a model. Extracted walnuts were subjected to nano-liquid chromatography–mass spectrometry (n-LC-MS/MS), and spectra were searched against databases made from a six-frame translation of the genome (6FT), a transcriptome, and three proteomes. Searches against proteomic databases yielded a variable number of peptides (1156–1275), and only ten additional unique peptides were identified in the 6FT database. Searches against a transcriptomic database yielded results similar to those of the National Center for Biotechnology Information (NCBI) proteome (1200 and 1275 peptides, respectively). Performance of the transcriptomic database was improved via the adjustment of RNA-Seq read processing methods, which increased the number of identified peptides which align to seed allergen proteins by ~20%. Together, these findings establish a path towards the construction of robust proxy protein databases for tree nut species and other non-model organisms. Full article
