Amla essential oil‐based nano‐coatings of Amla fruit: Analysis of morphological, physiochemical, enzymatic parameters, and shelf‐life extension

Abstract

Amla, also called Indian gooseberry (Phyllanthus emblica L.), is an indigenous fruit of the Indian subcontinent and belongs to the family Euphorbiaceae. Due to its numerous health benefits, Amla is also considered a "wonder fruit for health" (Singh et al., 2014).Amla fruit is a highly nutritive fruit that comprises a considerable amount of vitamin C, hydrolyzable tannins, alkaloids, phenols, flavonoids, minerals, and amino acids. Among the tannins, flavonoids, and phenolic compounds, Emblicanin A and B, ellagic acid, and gallic acid have biological activities. These constituents make Amla fruit a wholesome package possessing various anti-oxidant, anti-cough, anti-anemic, anti-aging, anti-inflammatory, antimutagenic as well as anti-cancer, and immunomodulatory properties (Hassan et al., 2020). Amla fruit is highly perishable and easily deteriorates within 5-6 days (Pathak et al., 2009). Postharvest losses in Amla fruit are up to 50 % on an annual basis as Amla fruits are highly susceptible to bruises, browning, desiccation, and fruit rot (Thomas, 1930). In terms of microbial infection, yeast and blue mold infestation are generally found on whole fruits when stored under normal atmospheric conditions due to the low pH content of Amla fruits (Kimball, 1999;Rivas et al., 2006). There are

Influence of Different Processing Conditions on Nutritional, Phytochemical, and Physical Properties of Aquatic Fern (Azolla pinnata): A Sustainable Nutrient-Rich Human Food

“…The chlorophyll content of the Azolla sample was measured as per the standard methodology of Barnes et al and described by Braich et al The absorbance was read at 645 and 663 nm, and Chlorophyll a , Chlorophyll b , and total chlorophyll were estimated by using the following formulas and expressed as mg/g dry weight. Chl 0.25em a = ( 12.47 × A 663 − 3.62 × A 645 ) × V 1000 × W .25ex2ex Chl b = ( 25.06 × A 645 − 6.5 × A 663 ) × V 1000 × W Total 0.25em chl = Chl a + Chl b …”

Progress of nanopreparation technology applied to volatile oil drug delivery systems

“…There are various options for encapsulating volatile oils into nanoscale particles, including polymer-based nanocarriers (microemulsions, nanoemulsions [ 7 ], liposomes [ 8 ], solid lipid nanoparticles, nanostructured lipid carriers, self-nanoemulsifying drug delivery systems), lipid-based nanocarriers (nanocapsules [ 9 ], nanomicelles). There are also multiple choices for nanoscale formulation technologies, mainly including self-nanoemulsification [ 10 ], phase inversion [ 11 ], high-speed shearing technology, spray drying method, high-pressure homogenization, ultrasonic technology [ 12 ], thin film hydration method, ethanol injection technology, nanoprecipitation technology, electrospinning, emulsion diffusion method, ion gelation.…”

Attenuation of Hyperlipidemia by Medicinal Formulations of Emblica officinalis Synergized with Nanotechnological Approaches

“…In addition, nanoencapsulated amla provides nutraceuticals and functional foods to improve human health. The therapeutic and traditional potential of amla can be fully utilized by nanoencapsulation of the active components of amla for target delivery, enhanced bioavailability, and increased bioactivity [8].…”
