Abstract

This is a PDF file of an article that has undergone enhancements after acceptance, such as the addition of a cover page and metadata, and formatting for readability, but it is not yet the definitive version of record. This version will undergo additional copyediting, typesetting and review before it is published in its final form, but we are providing this version to give early visibility of the article.

Morphological Changes and Component Characterization of Coffee Silverskin

“…It is non-destructive, simple, and fast, and it can be used to perform qualitative and quantitative analysis on a variety of substances at the same time. It is now widely used in the food industry [ 15 , 16 , 17 ]. At the same time, NMR spectroscopy has been successfully used in the analysis of the composition of green coffee [ 18 ], roasted coffee [ 19 ], the effect of roasting on coffee composition [ 20 ], and coffee flavor [ 21 ].…”

Recent Applications of Benchtop Nuclear Magnetic Resonance Spectroscopy

“…Benchtop NMR spectroscopy can also be applied to the analysis of dairy products, which have been probed by time-domain NMR techniques to determine fat/moisture content and authenticity as well as to perform quality control [29]. Recently, benchtop NMR spectroscopy has been used to investigate the production conditions of lactose-free milk [26], which is produced by the lactase-catalyzed breakdown of lactose into galactose and glucose. In this case, traditional analytical techniques such as polarimetry, mid-IR spectroscopy, and high-performance liquid chromatography (HPLC) are poorly suited for the online monitoring of hydrolysis in flow mode via lactose content determination [30].…”

“…In this case, traditional analytical techniques such as polarimetry, mid-IR spectroscopy, and high-performance liquid chromatography (HPLC) are poorly suited for the online monitoring of hydrolysis in flow mode via lactose content determination [30]. Soyler et al demonstrated the applicability of benchtop NMR spectroscopy as a tool for online lactose hydrolysis monitoring in a model system for the production of lactose-free milk [26]. Milk samples were also classified based on processing type, milk source, and geographic origin.…”

Türki̇ye'de Üç Bölgeden Toplanan Geleneksel Sütleri̇n Metaboli̇k İçeri̇ği̇ni̇n NMR Spektroskopi̇si̇ İle Anali̇zi̇

“…Monakhova et al (2012) investigated the labelling accuracy of milk, lactose-free milk, and other milk derivatives (soy, oat, rice) in the markets by 1H NMR spectroscopy (Monakhova et al, 2012). Söyler et al (2021) investigated the advantages of bench-top NMR spectroscopy as a quality-control tool at different stages of milk production. First, bench-top NMR was used to monitor lactose hydrolysis.…”

“…First, bench-top NMR was used to monitor lactose hydrolysis. The artificial neural network model has been developed to classify the different components of milk samples by supporting benchtop NMR spectroscopy (Söyler et al, 2021). Laref (2020) has suggested that using the bioinformatics software following 1H NMR is more advantageous for metabolite identification (Laref, 2020).…”
