Special Issue Information

Dear Colleagues,

We are inviting submissions to a Special Issue on the application of spectral techniques in agricultural products and food analysis.

Spectroscopic techniques are rapid, non-destructive and environmentally friendly analysis techniques for agricultural production, products that are being processed and finished products for food and non-food uses. They make it possible to estimate different characteristics that determine the quality of these products, such as their overall chemical and nutritional composition. Similarly, they can find applications in the authentication of products such as orange juice, dairy products, and meat as well as in the detection of contaminants (animal meal, impurities, etc.) and in the traceability of meat. We have chosen to limit the spectral techniques to Raman spectroscopy, SERS (Surface-Enhancing Raman Scattering), NIR, MIR, and Fluorescence spectroscopy. The complexity of the spectra obtained from the types of products studied can lead to the use powerful chemometric tools. Chemometrics, which uses mathematical and computer methods to visualize, extract and process the information contained in Infrared, Raman and Fluorescence spectra, has demonstrated a great ability to provide powerful models to classify and predict product quality parameters. This Special Issue is an opportunity to present chemometric classification and prediction models that are based on the coupling of spectral techniques with chemometric tools.

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. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Among the most studied natural polymers, alginate, a natural polysaccharide extracted from algae is well known due to its applications related to remarkable properties such as biocompatibility, biodegradability and low toxicity. In order to optimize the physicochemical properties of alginate and starch-based biofilms reinforced by glycerol, we propose of different biofilms by Raman spectroscopy according to the mass proportion of alginate in water: 1%, 2%, 3%, 4% and 5%. The first vibrational study of alginate-based biofilms demonstrated a link between the mass proportion of alginate in water with the contribution of hydrogen bonds through vibrational modes at 1570, 1500 and 1414 cm−1 and with the vibrational contributions of gauche and trans conformational C-C stretching at 1098 and 1068 cm−1, respectively. This link seems to persist in the case of biofilms based on alginate reinforced by glycerol with a lower intensity. For the cases of alginate and starch-based biofilms and glycerol-reinforced alginate–starch biofilms, the impact of the mass proportion of alginate in water on the hydrogen bonds is evaluated by determining an area ratio τ=Area1414/Area1340 between the mode 1414 cm−1 assigned to the hydrogen bonds and 1340 cm−1 assigned to d(O-H) in plane. The vibrational results show interaction between the proportion of alginate and the hydrogen bonds. Full article
