Special Issue Information

Dear Colleagues,

The science of food technology includes the study of the physical, chemical and biological characteristics of the constituents of raw materials, intermediate products and finished food, as well as the changes that occur during processing, transportation and storage. Using the natural features of plant and animal raw materials, technology applies such forms of processing which enable one to obtain a food product with high quality, high nutritional value and a long shelf life. Food processing usually consists of processing pretreatment, which includes cleaning, rinsing and slicing, and substantial processing, associated with thermal processing of the food. The activities undertaken in food processing are aimed at the elimination of undesirable contaminants, microorganisms, and non-nutritive components, the inactivation of enzymes, increasing the digestibility and assimilability of nutrients, improving structure and texture, and imparting appropriate organoleptic characteristics.

On the other hand, the application of these technological treatments may have a negative effect on health-promoting ingredients, causing their loss at each stage of processing. It is important to apply or develop technologies which retain or even enhance the activity of bioactive components in food systems.

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. Molecules 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 2700 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.

Microbial fermentation has been widely used to improve the quality and functional composition of food and edibles; however, the approach has rarely been applied to traditional Chinese medicines. In this study, to understand the effect of microbial fermentation on the active ingredients of traditional Chinese medicines, we used Bifidobacterium bifidum and Bacillus subtilis to ferment the traditional Chinese medicine, Cornus officinalis fruit (COF), and determined the levels of active ingredients using HPLC (high-performance liquid chromatography). According to the results, both B. subtilis and B. bifidum substantially increased the amount of gallic acid in the COF culture broth after fermentation; however, the two species of bacteria had no effect on the loganin content. Moreover, the B. subtilis fermentation reduced the contents of ursolic acid and oleanolic acid in the COF broth, whereas the B. bifidum fermentation did not. This study contributes to a better understanding of the mechanism by which microbial fermentation alters the active ingredient levels of traditional Chinese medicines, and suggests that fermentation may potentially improve their functional ingredients.
