ESG approach in the valorization of cocoa (Theobroma cacao) by-products by subc...
Švarc-Gajić, Jaroslava; Brezo-Borjan, Tanja; Dzedik, Valentin; Rodrigues, Francisca; Morais, Simone; Delerue-Matos, CristinaIn this research valorization potentials of cocoa hull extracts in cosmetic industry, following Environmental, Social, and Governance (ESG) criteria, have been investigated and reported, presenting increased value of this biowaste. The extracts of cocoa hull obtained by subcritical water were characterized in respect to chemical composition and certain bioactive properties, and were used to develop functional c...
Development and Characterization of Functional Cookies Enriched with Chestnut S...
Pinto, Diana; Moreira, Manuela M.; Vieira, Elsa F.; Švarc-Gajić, Jaroslava; Vallverdú-Queralt, Anna; Brezo-Borjan, Tanja; Delerue-Matos, CristinaChestnut (Castanea sativa) shells (CSs), an undervalued agro-industrial biowaste, have arisen as a source of bioactive compounds with promising health-promoting effects. This study attempted, for the first time, to develop a functional food, namely cookies, using a CS extract obtained by an eco-friendly technology (subcritical water extraction). The cookies were characterized regarding their nutritional composi...
Potential therapeutic application of chestnut shells in oral mucositis treatmen...
Ferreira, Ana Sofia; Silva, Ana Margarida; Pinto, Diana; Ferraz, Ricardo; Moreira, Manuela M.; Švarc-Gajić, Jaroslava; Costa, PauloOral mucositis (OM), a common side effect of oncological treatment, is an inflammatory condition characterized by painful ulcerations, difficulty swallowing and speaking, and increased risk of infection, which can compromise the primary treatment outcome. The use of natural antioxidants to inhibit theredox imbalance responsible for OM development has emerged as an interesting approach for OM prevention and trea...
Influence of temperature on the subcritical water extraction of Actinidia argut...
Silva, Ana Margarida; Luís, Ana Sofia; Moreira, Manuela M.; Ferraz, Ricardo; Brezo-Borjan, Tanja; Švarc-Gajić, Jaroslava; Costa, Paulo C.Actinidia arguta is a species disseminated in Europe and classified by the Chinese Herbal Medicine as a medicinal plant. The fruit (kiwiberry) has been extensively exploited for multiple purposes, while leaves where discarded. The objective of this study was to evaluate the optimal Subcritical Water Extraction (SWE) temperature (110 °C - 160 °C) of antioxidants and polyphenols from A. arguta leaves. The optimal...
Chemical composition and bioactivity of oilseed cake extracts obtained by subcr...
Švarc-Gajić, Jaroslava; Rodrigues, Francisca; Moreira, Manuela M.; Delerue-Matos, Cristina; Morais, Simone; Dorosh, Olena; Silva, Ana MargaridaRecovery of bioactive compounds from biowaste is gaining more and more interest in circular economy models. The oilseed cakes are usually insufficiently exploited by most technologies since they represent valuable matrices abundant in proteins, minerals, and phytochemicals, but their use is mostly limited to feed ingredients, fertilizers or biofuel production. This study was thus focused on the exploration of n...
Salicornia ramosissima: A New Green Cosmetic Ingredient with Promising Skin Eff...
Correia, Ana; Silva, Ana Margarida; Moreira, Manuela M.; Salazar, Miguel; Švarc-Gajić, Jaroslava; Brezo-Borjan, Tanja; Cádiz-Gurrea, Maria de la LuzThis study aims to validate a new cosmetic ingredient from Salicornia ramosissima S J. Woods through in vitro and ex vivo assays. The halophyte extracts were obtained by subcritical water extraction (SWE) at different temperatures (110, 120, 140, 160 and 180 °C). The antioxidant/radical scavenging activities and the phenolic profile were screened for all extracts. The optimal extract was assessed in keratinocyt...
New Perspectives on the Sustainable Employment of Chestnut Shells as Active Ing...
Ferreira, Ana Sofia; Silva, Ana Margarida; Pinto, Diana; Moreira, Manuela M.; Ferraz, Ricardo; Švarc-Gajić, Jaroslava; Costa, Paulo C.Oral mucositis (OM), a common side effect of oncological treatment, is an oral mucosal disorder characterized by painful ulcerations and increased risk of infection. The use of natural antioxidants to suppress the redox imbalance responsible for the OM condition has emerged as an interesting approach to prevent/treat OM. This study aims to explore the chestnut (Castana sativa) shells as potential active ingredi...
Chemical Characterization and In Vitro Bioactivity of Apple Bark Extracts Obtai...
Švarc-Gajić, Jaroslava; Cerdà, Víctor; Delerue-Matos, Cristina; Mašković, Pavle; Clavijo, Sabrina; Suarez, Ruth; Cvetanović, AleksandraRecently, the value of wood residues has received increasing attention due to the presence of pharmacologically active compounds. In the present study, apple bark was treated with subcritical water (SWE) with the aim of bioactivity determination and chemical analysis by GC–MS applying two different sample preparation protocols and by HPLC. Extracts were screened for their total antioxidant capacity by means of ...
Valorization Potential of Oilseed Cakes by Subcritical Water Extraction
Švarc-Gajić, Jaroslava; Morais, Simone; Delerue-Matos, Cristina; Vieira, Elsa F.; Spigno, GiorgiaThe oil industry generates great quantities of oilseed cakes that remain after oil extraction. New technologies are required for their valorization, owing to their high nutritional value. Pumpkin, flax and hemp seed cakes were extracted by subcritical water under different conditions that included different gas atmospheres and homogenous catalysis, and for the first time their properties were directly compared....
Vine-Canes as a Source of Value-Added Compounds for Cosmetic Formulations
Moreira, Manuela M.; Rodrigues, Francisca; Dorosh, Olena; Pinto, Diana; Costa, Paulo C.; Švarc-Gajić, Jaroslava; Delerue-Matos, CristinaThe majority of works about vine-canes are focused on the evaluation of their chemical composition and antioxidant potential. To the best of our knowledge, the possible applications of produced extracts in cosmetic formulations have never been explored. The aim of the present study was to evaluate the antioxidant properties of vine-canes subcritical water extracts for use as active ingredients in the cosmetic i...
