“…Tang and coworkers (2015) reported a similar betanin and isobetanin content in red and black quinoa cultivated in Canada than that found in beet root although quantitative data were not provided [69]. A recent study has allowed identifying novel betacyanins and betaxanthins in 29 Peruvian quinoa varieties, correlating their presence with the high antioxidant and free radical scavenging activities measured in grain extracts [89]. These authors suggest that colored quinoa seeds might be interesting as a natural source of bioactive betalains.…”

Background: Quinoa (Chenopodium quinoa Willd.) is a pseudocereal traditionally cultivated by Andean cultures which production and consumption has increased worldwide in the last decades. Quinoa was defined as “one of the grains of the 21st century” because of its resistance to extreme environmental conditions and its nutritional and functional properties. In addition to its high content in protein, lipids, fiber, vitamins, and minerals, and its excellent balance of essential amino acids, quinoa contains a plethora of phytochemicals including saponins, phytosterols, phytoecdysteroids, phenolic compounds, polysaccharides, and bioactive proteins and peptides. The recent investigations demonstrating the beneficial effects of these compounds on metabolic, cardiovascular, and gastrointestinal health have made quinoa to gain recognition as a functional food and nutraceutical. This review summarizes the available data on the nutritional and functional role of quinoa emphasizing on the bioactive compounds mainly responsible for the health benefits attributed to this crop. Keywords: quinoa, pseudocereal, nutritional value, bioactive compounds, health benefits

“…Flavonoids in quinoa seeds include quercetin, rutin and kaempferol derivatives. The quinoa grains also possess bound phenolics, which are so named because they are bound with structures of the cell wall such as pectin, lignin cellulose, hemicellulose (arabinoxylans) and also with rod-shaped structural proteins [83][84][85][86][87][88][89][90][91][92][93][94][95][96][97][98]. Quinoa grains contain a lower amount of bound phenolics as compared to the free phenolics [14,81,85].…”

Quinoa is a climate-resilient food grain crop that has gained significant importance in the last few years due to its nutritional composition, phytochemical properties and associated health benefits. Quinoa grain is enriched in amino acids, fiber, minerals, phenolics, saponins, phytosterols and vitamins. Quinoa possesses different human-health promoting biological substances and nutraceutical molecules. This review synthesizes and summarizes recent findings regarding the nutrition and phytochemical properties of quinoa grains and discusses the associated biological mechanisms. Quinoa grains and grain-based supplements are useful in treating different biological disorders of the human body. Quinoa is being promoted as an exceptionally healthy food and a gluten-free super grain. Quinoa could be used as a biomedicine due to the presence of functional compounds that may help to prevent various chronic diseases. Future research needs to explore the nutraceutical and pharmaceutical aspects of quinoa that might help to control different chronic diseases and to promote human health.

“…Poly(lactide-co-glycolide) (PLGA), an FDA-approved polymer, has been widely used in biomedical fields such as drug delivery because of its biodegradability, biocompatibility, and controlled delivery properties [10]. Poly(lactide-co-glycolide) can also be used to encapsulate hydrophobic active compounds, and has shown great potential for improving the effectiveness of delivery in food systems [11,12]. In addition, essential oils including cinnamon bark extract and eugenol were incorporated in PLGA, and exhibited efficient antimicrobial activity [13,14].…”

Microencapsulation of Thymol in Poly(lactide-co-glycolide) (PLGA): Physical and Antibacterial Properties

et al. 2019

Thymol has been shown to be a safe and effective broad-spectrum antimicrobial agent that can be used as a food preservative. However, its volatile characteristics and strong odor limit its use in food products. The microencapsulation of this essential oil in biopolymers could overcome these disadvantages. In this work, thymol-loaded poly(lactide-co-glycolide) (PLGA) microparticles were successfully prepared and the optimal encapsulation efficiency was obtained at 20% (w/w) thymol. Microparticles containing thymol presented a spherical shape and smooth surface. Microencapsulation significantly improved the thermal and storage stability of thymol. In vitro release profiles demonstrated an initial fast release followed by a slow and sustained release. Thymol-loaded microparticles had strong antibacterial activity against Escherichia coli and Staphylococcus aureus, and the effectiveness of their antibacterial properties was confirmed in a milk test. Therefore, the thymol-loaded microparticles show great potential for use as an antimicrobial and as preservation additives in food.
