In this study, the gas atmosphere of packed poultry was monitored using optical measurement systems based on fluorescence quenching for oxygen determination and mid-infrared (MIR) laser spectroscopy for the detection of carbon dioxide. The gas atmosphere was evaluated continuously over fifteen days of storage, the total viable count was obtained, and optical and olfactory sensory evaluations were simultaneously performed by a trained sensory panel. The results revealed that irregular storage conditions could be detected and that microbiological growth under regular conditions does not lead to a significant change in the headspace atmosphere.","PeriodicalId":194447,"journal":{"name":"Foods 2021","volume":"167 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114482538","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nowadays, there is a development in research to identify natural functional food sources high in bioactive compounds, such as antioxidants and polyphenols, as they are shown to contribute towards decreasing oxidative stress and maintaining well-being in human health. The objective of the present study was to determine the total antioxidant capacity and total phenolic content of Mediterranean medicinal natural herbs and wild greens aiming to create a database of medicinal plants for future potential use as functional food ingredients. A total of seventeen selected herbs and wild greens from Lemnos Island (Greece) were purchased between June and July of 2021. Extracts were prepared with an ultrasound water bath at 70 °C for 60 min. The antioxidant capacity was measured with ferric reducing antioxidant power (FRAP) assay and the total polyphenolic content was determined with the Folin-Ciocalteau reagent method. The mean phenolic values ranged from 0.18 to 2282.80 mg of gallic acid/g of sample, whereas Hypericum perfoliatum L. and Hypericum perforatum L., Salvia spp., and Sideritis sp. displayed the highest contents (p < 0.05). Melissa officinalis L., Mentha Spicata, and Thymbra capitata L. obtained the highest total antioxidant capacity, values greater than 12.20 mmol/L, with an average range of 0.06 to 30.58 mmol of Fe2+/L of extract (p < 0.05). Pistacia lentiscus var. chia, Crataegus azarolus L., and Pancratium Maritimum obtained the lowest contents from both methods. Studies have shown that medicinal plants with total antioxidant values higher than 0.87 mmol/L could be applicable in the fortification of food products (i.e., yogurt). Therefore, this study suggests that most of the above medicinal plants could be a potential source of antioxidants for functional food applications while their use can enhance Mediterranean diet principles.","PeriodicalId":194447,"journal":{"name":"Foods 2021","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128097975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
