“…Therefore, we investigated specific compounds within the extract that have ASE-like effects on atopic dermatitis. Acorns from the diverse Quercus species are reported to generally contain a variety of phenolics, such as gallic acid, ellagic acid, their derivatives and tannins [23]. Phytochemical analysis of ASE was confirmed by HPLC/MS analysis.…”

To investigate the potential effects of acorn shells on atopic dermatitis (AD), we utilized oxazolone (OX)-or 2,4-dinitrochlorobenzene (DNCB)-induced AD-like lesion mouse models. Our research demonstrates that Acorn shell extract (ASE) improved the progression of AD-like lesions, including swelling, which were induced by oxazolone on Balb/c mouse ears. Additionally, ASE significantly decreased the ear thickness (OX: 0.42 ± 0.01 mm, OX-ASE: 0.32 ± 0.02 mm) and epidermal thickness (OX: 75.3 ± 32.6 µm, OX-ASE: 46.1 ± 13.4 µm). The continuous DNCB-induced AD mouse model in SKH-1 hairless mice demonstrated that ASE improved AD-like symptoms, including the recovery of skin barrier dysfunction, Immunoglobulin E hyperproduction (DNCB: 340.1 ± 66.8 ng/mL, DNCB-ASE: 234.8 ± 32.9 ng/mL) and an increase in epidermal thickness (DNCB: 96.4 ± 21.9 µm, DNCB-ASE: 52.4 ± 16.3 µm). In addition, we found that ASE suppressed the levels of AD-involved cytokines, such as Tumor Necrosis Factor α, IL-1β, IL-25 and IL-33 in both animal models. Furthermore, gallic acid and ellagic acid isolated from ASE suppressed β-hexosaminidase release and IL-4 expression in RBL-2H3 cells. The acorn shell and its active phytochemicals have potential as a new remedy for the improvement of atopic dermatitis and other inflammatory diseases.

In this study, we evaluated the effect of some Romanian local plant raw materials on the rheological, physicochemical, and sensory properties of natural yogurt. These plants were added as a 2% powder in the set yogurt recipe and the finished products obtained under the same conditions were compared to a control sample. By adding plant powders, the rheological properties of yogurt were improved, the syneresis was reduced, and the water holding capacity of the yogurt samples was increased. The highest values for rheological properties were obtained for yogurt with buckwheat flour (YBF) and the lowest values for the same parameters were obtained for control yogurt (YC). The lowest value of syneresis was obtained for YBF, followed by the yogurt with beetroot powder (YBP), and the yogurt with acorn flour (YAF). The best results from sensory and physicochemical point of view were recorded by the yogurt with added 2% buckwheat flour. Practical applications The results of the study lead to determining the formulation of a novel yogurt, with the best sensory acceptance, rheological, and physicochemical properties. Because of its universal popularity, there is a high economic importance in diversifying yogurt products. The use of local vegetable resources as raw materials for obtaining yogurt leads to their superior capitalization, as well as obtaining finished products with beneficial effects on the health of the consumers. Scientific impact of this study is by obtaining innovative products using domestic raw materials that not only improve consumer health, but also increase final product shelf life. Socio‐economic impact of the project is to increase consumer confidence in finished products and reduce losses by lowering the number of market returned products and by also increasing turnover.

Mapping the Lisbon Potential Foodshed in Ribatejo e Oeste: A Suitability and Yield Model for Assessing the Potential for Localized Food Production

Abstract:Research on food planning has been recently proposed in North American and European planning to account for how cities might change their food provision to respond to the rising demands for a more sustainable and ethical food system. The purpose of this paper was to evaluate the agro-ecological potential of the Lisbon city region, Ribatejo e Oeste, to increase its Regional Food Self-Reliance (RFSR), through adopting demand restraint and food system relocalization approaches to food system sustainability. Three new diet scenarios were considered: meat-based, plant-based and strict vegetarian, defined in accordance with healthy dietary patterns. We used agro-climatic and agro-edaphic agricultural suitability models to evaluate the agro-ecological potential for RFSR, and proposed the use of Foodshed Landscape Plans within a landscape planning methodology. Results showed the extent of local food production that could improve food self-reliance, with 72%, 76%, 84% of total food needs in the meat-based, plant-based, and strict vegetarian scenarios, respectively. Thus, food system transformation by means of relocalization, is therefore ecologically feasible and would ensure the sustainable use of the ecological basis of food security. Additionally, a dietary transition would imply significant land sparing, which strengthens the demand restraint perspective for a transition to food system sustainability.
