“…However, it was higher compared to our study and significantly influenced the ability of these extracts to reduce free DPPH radicals. On the other hand, the total polyphenol content in the powdered extracts from white mulberry leaves from Poland was similar to the values obtained in our experiment and amounted to 42.6 mg GAE/g DM [42]. Similar TPC values were also determined for leaf extracts of mulberry belonging to one of the three cultivars from the South China studied [21].…”

Plants are a valuable source of biologically active molecules, mainly phenolic compounds. In the present study, the total phenolic content (TPC), DPPH· and ABTS+ scavenging activity as well as ferric reducing ability (FRAP) of aqueous ethanolic (70%) extracts of Cistus incanus L. and Asarum europaeum L. herb, Geum urbanum L. rhizome, Angelica archangelica L. root, white mulberry (Morus alba L.), lemon balm (Melisa officinalis L.), red raspberry (Rubus idaeus L.) and Betula pendula Roth. leaves were determined. In addition, the phenolic profiles of the studied plant extracts and antibacterial activity have been investigated. The extracts from C. incanus and G. urbanum demonstrated the highest TPC and antioxidant capacity, while the extracts from A. archangelica and white mulberry were characterized by the lowest values. A remarkable correlation was also found between the TPC and antioxidant activity of the examined extracts. HPLC analysis showed that the studied extracts were sources of both phenolic acids and flavonoids. More flavonoids than phenolic acids were identified in the extracts of C. incanus, M. alba, R. idaeus and B. pendula compared to the other extracts tested. Not all extracts showed a significant impact on the growth of the tested bacterial strains. Escherichia coli was the most sensitive strain to lemon balm extract (MIC, 0.125 mg/mL), whereas the strains of Acinetobacter baumannii and Bordetella bronchiseptica were sensitive to the G. urbanum extract (MIC, 0.125 mg/mL). Among Gram-positive bacteria, Enterococcus faecalis was the most sensitive to G. urbanum extract. In turn, Staphylococcus aureus and Staphylococcus epidermidis were sensitive to the extracts from C. incanus herb (MIC, 0.125 mg/mL), red raspberry (MIC, 0.125 mg/mL) and lemon balm leaves (MIC. 0.25 mg/mL). Based on the obtained results, the applicability of the studied plant extracts as additives to food and cosmetic products may be considered in the future.

“…Anthocyanins have got attention as they possess diverse health potentials such as anti-inflammatory and antioxidant (Hu et al, 2017). Different anthocyanins have been identified and evaluated in mulberry (Przygoński and Wojtowicz, 2019;Smailagić et al, 2019). Mulberry anthocyanins have significant ability to inhibit lipid oxidation and migration of B16−F1 cells, showing antimetastasis activity (Lee et al, 2019).…”

Plants belonging to this family are distributed across a vast range of evergreen forests in tropical regions (De Sousa et al., 2016). Genus Morus of this family has 24 species with at a minimum 100 known varieties (Negro et al., 2019;Rodrigues et al., 2019). Plants of this genus grow under cultivation and also in the wild in different areas particularly in Asia, Southern Europe, America and several areas of Africa (Ionica et al., 2017). Mulberry plants belong to this particular genus and are distributed in different climatic conditions across the globe, ranging

Innovative Management of Vegetable Outgrades as a Means of Food Loss and Waste Reduction

The present research focuses on using plant waste from agricultural production chains (vegetable outgrades) as ingredient sources for innovative food strategy developments. The quality of multi-vegetable products made from frozen vegetable outgrades (broccoli, cauliflower, green and yellow cut beans) for serving in gastronomy was evaluated. Vegetable outgrades were found to be low-cost sources of nutritional components. The dietary fiber content varied from 2.35 (cauliflower Giewont cultivar) to 4.40 g/100 g (green bean Rimember cultivar). The protein content varied from 1.41 (green bean Opportune cultivar) to 2.58 g/100 g (broccoli Porthenon cultivar). Bioactive compounds, including polyphenols and vitamin C, varied significantly depending on the vegetable. The content of carotenoids (β-carotene and zeaxanthin) in vegetables, in particular broccoli (Larson cultivar) and green beans (Rimember and Opportune cultivars), was lower than in outgrades. Due to the high nutrient quality of outgrades, the preparation of mechanically-formed vegetable patties and paste proceeded. According to recommendations of NRF, NAS, NDS nutrient density indices, both patties and pastes were classified as products with rich nutritional value and full-valuable components of the human diet. Moreover, food production technology utilizing vegetable outgrades can be potential solutions for food loss and waste management in gastronomy and in the food production industry.
