Special Issue Information

Dear Colleagues,

Vitamin E  refers to a group of eight lipophilic compounds (also called E-vitamers): the α-, β-, γ- and δ-tocopherols and the α-, β-, γ- and δ-tocotrienols. Among them, α-tocopherol is the most abundant form of vitamin E in animal tissue and has the highest activity in carrying out the essential antioxidant functions of vitamin E. For these reasons, α-tocopherol is generally considered “the Vitamin E” in nutrition. However, α-tocopherol is not the only E-vitamer compound present in foods and all vitamin E forms and their metabolites appear to have significant and sometimes quite different metabolic effects. The α-tocopherol functions in the human body, including antioxidant, anti-inflammatory and anti-atherogenic actions, as well as direct effects on enzymatic activities and modulation of gene transcription, have been extensively studied. The newest research is focusing attention on the health benefits of tocotrienols, particularly in the prevention or treatment of non-communicable diseases, such as cardiovascular, musculoskeletal, metabolic, gastric, skin disorders and cancers.

In view of this, to evaluate the functional effects of Vitamin E on human health, it is essential to know the vitamin E content and profile in foodstuffs, to define the bioavailability of different vitamin E forms and to evaluate the bioactivity of their metabolites.

In this Special Issue, we invite researchers to provide original research articles, reviews, and clinical reports that relate to:

  • Novel food sources of Vitamin E
  • Impact of environmental and genetic factors and emerging technological treatments on Vitamin E food content
  • Vitamin E bioavailability
  • Vitamin E forms and metabolites
  • Vitamin E and human health.

We are waiting for articles from researchers in a wide range of fields such as food chemistry, food technology, biochemistry, medicine, nutrition, and epidemiology.

We want to make this Special Issue a valued accumulation of new knowledge in this field.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. 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. Antioxidants is an international peer-reviewed open access monthly journal published by MDPI.

Gamma-tocopherol methyltransferase (γ-TMT), a key gene in the vitamin E biosynthesis pathway, significantly influences the accumulation of tocochromanols, thereby determining rice nutritional quality. In our study, we analyzed the γ-TMT gene in 475 Korean rice accessions, uncovering 177 genetic variants, including 138 SNPs and 39 InDels. Notably, two functional SNPs, tmt-E2-28,895,665-G/A and tmt-E4-28,896,689-A/G, were identified, causing substitutions from valine to isoleucine and arginine to glycine, respectively, across 93 accessions. A positive Tajima’s D value in the indica group suggests a signature of balancing selection. Haplotype analysis revealed 27 haplotypes, with two shared between cultivated and wild accessions, seven specific to cultivated accessions, and 18 unique to wild types. Further, profiling of vitamin E isomers in 240 accessions and their association with haplotypes revealed that Hap_2, distinguished by an SNP in the 3′ UTR (tmt-3UTR-28,897,360-T/A) exhibited significantly lower α-tocopherol (AT), α-tocotrienol (AT3), total tocopherol, and total tocotrienol, but higher γ-tocopherol (GT) in the japonica group. Additionally, in the indica group, Hap_2 showed significantly higher AT, AT3, and total tocopherol, along with lower GT and γ-tocotrienol, compared to Hap_19, Hap_20, and Hap_21. Overall, this study highlights the genetic landscape of γ-TMT and provides a valuable genetic resource for haplotype-based breeding programs aimed at enhancing nutritional profiles. Full article
