In this work, visible near-infrared (vis-NIR) spectroscopy combined with the sparsity of interval partial least square regression (iPLS) were carried out to measure the egg\u2019s freshness by semi-transmittance spectral acquisition. A fiber spectrometer with a spectral range of 550-985 nm was embedded in the developed spectral scanner, which was designed with rich light irradiation mode from another two reflective surfaces. The semi-transmittance spectra were collected from the waist of eggs and monitored every two days. Haugh unit (HU) is a key indicator of egg\u2019s freshness, and ranged 56\u201391 in 14 days after delivery. The profile of spectra was analyzed the relation to the changes of egg\u2019s freshness. A series of iPLS models were constructed on the basis of spectral intervals at different divisions of the spectral region to predict the egg\u2019s HU, and then the least absolute shrinkage and selection operator (Lasso) was used to sparse the number of iPLS member models acting as a role of model selection and fusion regression. By optimization of the number of spectral intervals in the range of 1 to 40, the 26th fusion model obtained the best performance with the minimum root mean of squared error of prediction (RMSEP) of 5.161, and performed the best among the general PLS model and other intervals-combined PLS models. This study provided a new, rapid, and reliable method for the non-destructive and in-site determination of egg\u2019s freshness.<\/jats:p>","DOI":"10.3390\/foods12010184","type":"journal-article","created":{"date-parts":[[2023,1,2]],"date-time":"2023-01-02T02:44:03Z","timestamp":1672627443000},"page":"184","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Non-Destructive Measurement of Egg\u2019s Haugh Unit by Vis-NIR with iPLS-Lasso Selection"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5255-4687","authenticated-orcid":false,"given":"Leiming","family":"Yuan","sequence":"first","affiliation":[{"name":"College of Electrical and Electronic Engineering, Wenzhou University, Wenzhou 325035, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xueping","family":"Fu","sequence":"additional","affiliation":[{"name":"College of Electrical and Electronic Engineering, Wenzhou University, Wenzhou 325035, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaofeng","family":"Yang","sequence":"additional","affiliation":[{"name":"College of Electrical and Electronic Engineering, Wenzhou University, Wenzhou 325035, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaojing","family":"Chen","sequence":"additional","affiliation":[{"name":"College of Electrical and Electronic Engineering, Wenzhou University, Wenzhou 325035, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guangzao","family":"Huang","sequence":"additional","affiliation":[{"name":"College of Electrical and Electronic Engineering, Wenzhou University, Wenzhou 325035, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8042-6658","authenticated-orcid":false,"given":"Xi","family":"Chen","sequence":"additional","affiliation":[{"name":"College of Electrical and Electronic Engineering, Wenzhou University, Wenzhou 325035, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wen","family":"Shi","sequence":"additional","affiliation":[{"name":"College of Electrical and Electronic Engineering, Wenzhou University, Wenzhou 325035, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6272-5339","authenticated-orcid":false,"given":"Limin","family":"Li","sequence":"additional","affiliation":[{"name":"College of Electrical and Electronic Engineering, Wenzhou University, Wenzhou 325035, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,1]]},"reference":[{"key":"ref_1","first-page":"89","article-title":"The Return of w3 Fatty Acids into the Food Supply","volume":"Volume 83","author":"Simopoulos","year":"1998","journal-title":"Designer Eggs and Their Nutritional and Functional Significance"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"727","DOI":"10.1007\/s00217-005-0145-4","article-title":"Methods to evaluate egg freshness in research and industry: A review","volume":"222","author":"Karoui","year":"2006","journal-title":"Eur.
