Natural Antioxidants: Innovative Extraction and Application in Foods compiles comprehensive information and recent findings on the extraction of antioxidants from different natural resources and investigates their application in food. The book focuses on different sources of natural antioxidants such as the Hypochaeris and Hyoseris species, pomegranate seed oil, thyme, hemp, coriander, olive mill wastewaters, the edible mushroom Hericium erinaceus, Brewer’s spent grain, broccoli byproducts, cardoon, and Norway spruce bark. Moreover, the effect of different treatments such as blanching, microwave exposure, roasting, and enzymatic browning on the phytochemical content and bioactivity of the extracts is also addressed. Readers will find valuable insights into the impact of extraction methodologies on the bioactivity of the extracts, along with an understanding of the vast potential of natural extracts for the quality of food products. Readership Food and nutrition researchers, health professionals, nutritionists, and food science and chemistry students

The main focus of this thematic collection is on the antimicrobial activity of essential oils and their combinations with conventional antimicrobial drugs, including the eradication of the existing biofilms, the explanation of the mechanisms underlying antimicrobial activity, and the preparation of stable formulations with essential oils, which boost their antimicrobial activity and provide greater stability. These issues are addressed in four research papers and three reviews, which present novel advances in the development and application of essential oils as antimicrobial agents via combinatorial and nano-based approaches.

Wine is a widely consumed beverage due to its unique and pleasant sensory properties. Wine is composed of more than one thousand chemical compounds (e.g., alcohols, esters, acids, terpenoids, phenolic compounds, flavonoids, anthocyanins, minerals, and vitamins, among others) resulting from several chemical and biochemical processes. Microextraction techniques in tandem with high-resolution analytical instruments have been applied by wine researchers to expand the knowledge of wine’s chemical composition with the purposes of improving wine quality, supporting winemaker decisions related to the winemaking process, and guaranteeing the authenticity of wine. As a result, we proposed “Chemical/Instrumental Approaches to the Evaluation of Wine Chemistry” as a topic for a Special Issue in Molecules. This Special Issue aims to provide an update on state-of-the-art extraction procedures (e.g., solid-phase microextraction (SPME)) and analytical tools (e.g., nuclear magnetic resonance (NMR), inductively coupled plasma mass spectrometry (ICP-MS), ultra-performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS)), emphasizing their use as suitable platforms for the establishment of the chemical composition of wine (volatomic profile, antioxidants, phenolic pattern, and elemental composition, among others). Information related to wine sensorial properties, contaminants, authenticity, and chemometric tools used for data treatment are described in this Issue.

Microalgae are photosynthetic organisms with the ability to sequester and convert atmospheric carbon dioxide into high-value bioactives, and are therefore seen as a renewable and sustainable bioresource in the fields of biofuels, aquaculture and animal feeds, bioremediation of waste, nutraceuticals, pharmaceuticals, cosmeceuticals and agriculture. Moreover, algae can adjust their metabolism according to surrounding growth conditions, and this metabolic flexibility can be exploited in industrial biotechnology with genetic and metabolic engineering, when compared to other photosynthetic organisms. The metabolome is the result of the combined effects of genetic and environmental influences on metabolic processes. Metabolomic studies can provide a global view of metabolism and thereby improve our understanding of the underlying biology. Advances in metabolomic technologies have shown utility for elucidating the mechanisms which underlie fundamental biological processes, including disease pathology. This book represents research papers based around metabolomics, to improve knowledge on the metabolome and metabolism in algae, with a focus on carbon and nitrogen resource allocation. It also describes many bioanalytical techniques and emphasizes their usefulness in microalgal biotechnology. Other aspects from an ecological, biotechnological and waste-water remediation perspective are also covered.
