Properties and Applications of Morinda citrifolia (Noni): A Review

Morinda citrifolia commonly known as noni is a perennial plant originating in Southeast Asia, consumed over 2000 years. Due to its versatility of adaptation and use of the structures of the plant for different therapeutic purposes, noni attracted the attention of researchers from the pharmaceutical and food industry. Chemical and nutritional analyzes already performed in M. citrifolia reveal the existence of more than 200 phytochemical substances with bioactive properties such as acids, alcohols, phenols, saccharides, anthraquinones, carotenoids, esters, triterpenoids, flavonoids, glycosides, lactones, iridoids, ketones, lactones, lignans, nucleosides, triterpenides, sterols, and aromatic compounds. The high nutritional value of M. citrifolia may induce therapeutic effects, including antimicrobial and antioxidant properties. The main industrial products from this plant are beverages (juice drinks), powders (from dried fruits), oil (from seeds), and leaf powders. Biological and phytotherapeutic applications of M. citrifolia are promising, but more extensive studies are still required. Thus, this review aims to gather updated and comprehensive information on Morinda citrifolia, discussing its traditional use, biochemical, phytotherapics, and toxicological properties, as well as the recent advances in the processing and standardization of products derived from noni fruit.     

Antarctic Krill (Euphausia superba) Oil: A Comprehensive Review of Chemical Composition,Extraction Technologies,Health Benefits,and Current Applications

Antarctic krill (Euphausia superba) oil has been receiving increasing attention due to its nutritional and functional potentials. However, its application as a novel food ingredient has not yet been fully explored. This review summarizes the chemical composition, extraction technologies, potential health benefits, and current applications of krill oil, with the aim of providing suggestions for its exploitation. Krill oil is a unique lipid consisting of diverse lipid classes and is characterized by a high concentration (39.29% to 80.69%) of phospholipids (PLs) associated with eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). It also contains considerable amounts of bioactive minor components such as astaxanthin, sterols, tocopherols, vitamin A, flavonoids, and minerals. The current technologies used in krill oil production are solvent extraction, nonsolvent extraction, super/subcritical fluid extraction, and enzyme‐assisted pretreatment extraction, which all greatly influence the yield and quality of the end‐product. In addition, krill oil has been documented to have various health benefits, including anti‐inflammatory effects, cardiovascular disease (CVD) prevention, women's health, neuroprotection, and anticancer activities. Although krill oil products used for dietary supplements have been commercially available, few studies have attempted to explore the underlying molecular mechanisms to elucidate how exactly the krill oil exerts different biological activities. Further studies should focus on this to improve the development of krill oil products for human consumption.     

Repurposing chia seed oil: A versatile novel functional food

Chia seed oil (CSO) has been recently gaining tremendous interest as a functional food. The oil is rich in with polyunsaturated fatty acids (PUFAs), especially, alpha linolenic acid (ALA), linoleic acid (LA), tocopherols, phenolic acids, vitamins, and antioxidants. Extracting CSO through green technologies has been highly efficient, cost-effective, and sustainable, which has also shown to improve its nutritional potential and proved to be eco-friendly than any other traditional or conventional processes. Due to the presence of valuable bioactive metabolites, CSO is proving to be a revolutionary source for food, baking, dairy, pharmaceutical, livestock feed, and cosmetic industries. CSO has been reported to possess antidiabetic, anticancer, anti-inflammatory, antiobesity, antioxidant, antihyperlipidemic, insect-repellent, and skin-healing properties. However, studies on toxicological safety and commercial potency of CSO are limited and therefore the need of the hour is to focus on large-scale molecular mechanistic and clinical studies, which may throw light on the possible translational opportunities of CSO to be utilized to its complete potential. In this review, we have deliberated on the untapped therapeutical possibilities and novel findings about this functional food, its biochemical composition, extraction methods, nutritional profiling, oil stability, and nutraceutical and pharmaceutical applications for its health benefits and ability to counter various diseases.
