Special Issue Information

Dear Colleagues,

The maximization of agricultural production as a primary or value-added product is necessary for the years of change we face.

However, more than 30% of primary production is diverted into alternative uses (value-added products). To maximize the utilization of agricultural products in their primary (fresh) phase, experts in primary farm production are invited to conduct and publish research related to value-added alternatives, ranging from the use of wax to packaging, pre-cut and dehydrated foods, beverages, nutrition bars, etc.; this research can occur in collaboration with food technologists, who understand recent lifestyle changes, with demand for healthy, easy to handle, and sensorily appealing food increasing.

The industrialization of food guarantees the presence of out-of-season products by converting fresh raw material into a more stable, available, and commercial product; it also contributes to food security and environmental protection. Your research could significantly impact the agro-industry, including producers and marketers of agricultural products. Thus, we invite you to publish research on the application of biotechnological or technological processes to strengthen these sectors.

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. Horticulturae is an international peer-reviewed open access monthly journal published by MDPI.

The tomato (Lycopersicon esculentum) is a prominent fruit in Mediterranean countries with established biological activities for consumers. Given the widespread distribution of the fruit and its large production, the need to utilize the by-products seems imperative. With a view to valorizing the main carotenoid of tomato processing industry waste, lycopene, as well as other bioactive compounds (i.e., polyphenols), the optimization of a green extraction method involving ultrasound-assisted bath extraction (UBAE) was carried out. The results showed that the optimized UBAE technique achieved substantial yields of total carotenoids (420.8 μg of lycopene equivalents per gram of dry weight (dw)) and total polyphenols (2.62 mg of gallic acid equivalents per gram of dw). Flavonoid naringin (0.48 mg/g dw) and non-flavonoid coniferyl alcohol (0.32 mg/g dw) were the most abundant identified polyphenols. However, comparison with a conventional stirring extraction revealed that the latter technique marked double figures in all assays, including antioxidant activity assays. The study revealed that UBAE was not a preferable technique for recovering carotenoids because of the possible degradation of labile compounds found in tomato processing industry waste. Given that the extraction solvent was pure ethanol, the study established a foundation for the development of a unique lycopene-enriched product in the food industry. It is essential to conduct additional studies using alternative food-grade solvents or other environmentally friendly extraction methods. Full article
