Special Issue Information

Dear Colleagues,

The aim of the Special Issue is to present a collection of studies dealing with different food commodities and their analysis conducted under different conditions, for example, different storage types and periods and after application of different technological steps. Submissions of manuscripts dealing with the analysis of bioactive compounds in different food commodities and their interactions in complex food matrices are of interest and will be considered for publication.

More specifically, the scope of the Special Issue includes studies focusing on the following issues:

a. Extraction techniques with different edible matrices

b. Quantitative analysis applied on edible matrices

c. Analysis comparison between results gained by different methodologies

d. Food and beverage qualitative and quantitative analysis

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. Separations 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 2600 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.

Azanza garckeana (F. Hoffm). Exell and Hillc. is an important food and medicinal plant that has been used in tropical Africa. Therefore, this study aimed to investigate the nutritional value of jakjak fruit using different analytical techniques. The obtained results have demonstrated that jakjak fruit is very rich in total soluble sugar, constituting about 48% of the dry weight. Moreover, the chromatographic analysis revealed that jakjak fruit contained a high amount of glucose, fructose, maltose, and ascorbic acid. Further, GC-MS analysis detected four compounds related to secondary metabolites. Some of these detected constituents have medicinal value. For example, phenol, 2,4-bis (1,1-dimethylethyl) has been reported to have many functions such as antioxidant activity, anticancer, antifungal, and antibacterial properties. Furthermore, the antioxidant potential of different concentrations of deionized water and methanolic extracts was estimated using 2,2-diphenyl-1-picrylhydrazyl (DPPH). The results showed that the scavenging activity of the DPPH radical was found to be raised with increasing concentrations of fruit extracts. The concentration (50%) of both methanol and deionized water gave the best inhibition percentage (91.7 and 84.4%), respectively. In contrast, the methanolic extract has shown significant results compared to deionized water. This study concluded that jakjak fruit is very rich in total soluble sugar and phenolic compounds, which can be used as a source of polysaccharides and antioxidants for the human diet as well as raw materials for downstream industries.
