Special Issue Information

Dear Colleagues,

The bioavailability of food intake is assessed using indicators of intake of nutrients, and has an impact on human health. Due to the difficulties in accessing intestinal contents in vivo, in vitro food absorption performance models were developed.

Most of the models used comprise two or three stages, and include stomach–intestine systems, thin oral cavity–stomach–small intestine systems, or stomach–small intestine–large intestine systems. In in vitro gastrointestinal tract models, different volume (weight) ratios between intestinal fluids can be recommended. Dialysis systems, ultrafiltration, or in vitro intestinal epithelial cell culture models are used as models for nutrient absorption studies. The most popular cell line used to study food absorption is the Caco-2 line. Its morphology and physiology are very similar to natural human enterocytes in vivo. The Caco-2 model is used to study the absorption of proteins, lipids, sugars, vitamins, antioxidants, mycotoxins and other food ingredients.

This Special Issue on “New Trends and Perspectives on In Vitro Digestion Processes and Applications” aims to further the innovative application of the in vitro digestion of food ingredients.

Topics of interest include, but are not limited to:

  • Presentation of novel in vitro digestion models;
  • Digestibility and bioavailability of nutrients: proteins, lipids, carbohydrates;
  • Digestibility and bioavailability of other bioactive substances: lipid and water soluble;
  • Transformation and interactions between components of food during in vitro digestion;
  • Changes in numbers and activity of faecal bacteria during in vitro digestion;
  • Simulation of small-intestinal epithelium.

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. Processes is an international peer-reviewed open access monthly 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).

Ginger (Zingiber officinale Roscoe.) starch is a waste product generated during the extraction of bioactive compounds from ginger. This study aimed to treat ginger starch with different freeze–thaw cycles and explore the effect on the functional components, physicochemical properties, and structural properties of ginger starch. The results of the study showed that as the number of freeze–thaw cycles increased, the content of resistant starch, amylose, total starch, and recrystallization in ginger starch increased significantly (p < 0.05). Freeze-dried ginger starch exhibited a C-type crystal structure in the X-ray diffraction pattern. The Fourier-transform infrared spectroscopy results also showed that the value of A1047/1022 increased, indicating that the freeze–thaw cycle would increase the degree of starch recrystallization. In terms of physical and chemical properties, compared with gelatinized starch, freeze–thawed starch had low swelling power, high solubility, low peak viscosity and breakdown, indicating higher thermal stability. In conclusion, freeze–thaw treatment can promote the formation of resistant starch from ginger starch and reduce starch hydrolysis, reflecting the potential of low–GI foods. We hope that ginger starch can be used as a raw material for new applications in functional foods. Full article
