Nanosized Particles of Silica and Its Derivatives for Applications in Various Branches of Food and Nutrition Sectors

Abstract

Nanosized particles of silica and its derivatives have been identified as versatile for a broad range of science, technology, and engineering applications. In this paper, an effort has been made to provide a short review from the available literature information on their applications in various branches of food and nutrition sectors. The information provided in this paper describes various parameters affecting their performances and efficiencies. The properties and applications of nanosilica and its derivatives have been compared with microsilica and bulk-silica for their performances. The use of nanosized particles of silica and its derivatives provides a number of advantages. Their efficiencies and performances are significantly higher than those of the traditional ones.

Toxicology of silica nanoparticles: an update

“…Nanosilica, also known as the nanoform (<100 nm) of silicon dioxide or silica nanoparticles (SiNPs), possesses distinct physico-chemical characteristics compared to its bulk form; smaller size materials have an increased surface-to-volume ratio and a higher surface reactivity (Oberdörster 2010 ; Napierska et al 2010 ). Due to their appealing properties, SiNPs are now extensively used in agriculture, food, and consumer products including cosmetics (Napierska et al 2010 ; Khot et al 2012 ; Kasaai 2015 ; Brinch et al 2016 ). Until 2012, nearly 1.5 million tons of SiNPs had already been placed in the global market (Liljenström et al 2013 ) and SiNPs became one of the three most produced nanomaterials (NMs) worldwide in 2013.…”

Increased Uptake of Silica Nanoparticles in Inflamed Macrophages but Not upon Co-Exposure to Micron-Sized Particles

“…In recent decades, the use of nanotechnology has increased in many industrial applications [ 1 ]. Among different nanomaterials (i.e., materials with any external dimensions in the nanoscale, 1–100 nm) [ 2 ], silica (SiO 2 ) nanoparticles (NPs) have attracted considerable attention in various applications due to their appealing physicochemical properties [ 3 , 4 ]. Based on the structure defined by X-ray-diffraction spectroscopy [ 5 ], there are two main forms of silica: amorphous and crystalline.…”

Nanoparticle production from HMDSO in atmospheric pressure argon‐oxygen plasma

“…Amorphous silica particles with a size below 100 nm have been used for numerous applications in industry for decades since they are inert and relatively easy to produce. They can be used, e.g., as thickening, filler, and insulation material . Another application is the addition of nanoparticles to powders to enhance its flowability.…”
