Pork cracklings are Danish snacks with high contents of protein and fat. They are consumed mostly during wintertime when sun exposure cannot fulfil human needs for vitamin D3. Pork cracklings were produced in an industrially friendly manner from UVB LED illuminated pork rind, using a combination of sous vide (85 \u00b0C, 60 min) and roasting in the oven (200 \u00b0C, 20 min). Thermal processing resulted in a significant loss of vitamin D3 (&gt;90%). Thus, the process was optimized by the UVB exposure of pork cracklings, i.e., after thermal processing. The produced pork cracklings had a vitamin D3 level of ~10 \u00b5g\/100 g, with a possibility of tailoring its final content. Furthermore, the fat content at 15\u201320% was a reduction of 50% compared to marketed products in 2021. No significant difference was found in the content of vitamin D3 during 31 days of storage in the air. A consumer preference test (n = 53) indicated that &gt;80% of participants liked the product and saw its potential as a new food source of vitamin D3.<\/jats:p>","DOI":"10.3390\/foods11050726","type":"journal-article","created":{"date-parts":[[2022,3,1]],"date-time":"2022-03-01T08:17:03Z","timestamp":1646122623000},"page":"726","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Bio-Fortified Pork Cracklings with UVB LED Tailored Content of Vitamin D3"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2052-3074","authenticated-orcid":false,"given":"Petra","family":"Lo\u017enjak \u0160varc","sequence":"first","affiliation":[{"name":"Research Group for Bioactives\u2014Analysis and Application, National Food Institute, Technical University of Denmark, Kemitorvet, 2800 Kongens Lyngby, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marzia","family":"Rahimi","sequence":"additional","affiliation":[{"name":"Research Group for Bioactives\u2014Analysis and Application, National Food Institute, Technical University of Denmark, Kemitorvet, 2800 Kongens Lyngby, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jesper","family":"T\u00f8nnesen","sequence":"additional","affiliation":[{"name":"Research Group for Bioactives\u2014Analysis and Application, National Food Institute, Technical University of Denmark, Kemitorvet, 2800 Kongens Lyngby, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dennis Dan","family":"Corell","sequence":"additional","affiliation":[{"name":"Department of Photonics Engineering, Diode Lasers and LED Systems, Technical University of Denmark, Frederiksborgvej 399, 4000 Roskilde, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul Michael","family":"Petersen","sequence":"additional","affiliation":[{"name":"Department of Photonics Engineering, Diode Lasers and LED Systems, Technical University of Denmark, Frederiksborgvej 399, 4000 Roskilde, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Grethe","family":"Hyldig","sequence":"additional","affiliation":[{"name":"Research Group for Bioactives\u2014Analysis and Application, National Food Institute, Technical University of Denmark, Kemitorvet, 2800 Kongens Lyngby, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4199-3427","authenticated-orcid":false,"given":"Jette","family":"Jakobsen","sequence":"additional","affiliation":[{"name":"Research Group for Bioactives\u2014Analysis and Application, National Food Institute, Technical University of Denmark, Kemitorvet, 2800 Kongens Lyngby, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1033","DOI":"10.3945\/ajcn.115.120873","article-title":"Vitamin D deficiency in Europe: Pandemic?","volume":"103","author":"Cashman","year":"2016","journal-title":"Am.
