Screening analysis of beer ageing using near infrared spectroscopy and the Successive Projections Algorithm for variable selection

► Near infrared spectroscopy (NIR) is used for screening analysis of aged beers. ► Variable selection is accomplished by using the Successive Projections Algorithm (SPA). ► Only one wavenumber is selected for screening analysis of non-alcoholic or alcoholic beers. ► NIR and SPA-LDA can be used for quality control of beer samples.
