The influences of CO2 incorporated in gas nanobubbles (NBs) on palm oil crystallisation and physical characteristics were investigated. Initially, CO2 NB-treated palm oil had a significantly (p ≤ 0.05) larger amount of dissolved CO2 (~ 1200–1700 ppm). The crystal morphology evaluation showed smaller size and higher number of palm oil crystals by th...

This work aims at examining the impact of generated CO2 nanobubbles (NBs) via the membrane-based method on physicochemical properties and surface tension of commercial clarified apple juice. The gas was injected at 300 kPa pressure for variable liquid circulation times (5, 13 and 26 min) to produce the CO2 NBs. Sets of 13- and 26-min circulation ti...

Viscosity is one of key parameters to handle liquid food during processing and transport. In this work, viscosities of apple juice concentrate (APJC) and canola oil (CANO) injected with CO2 nanobubbles (NBs), having size ranged approximately from 50 to 850 nm, were investigated. A significant (p≤0.05) viscosity reduction was observed by up to 18% a...

The objective of this research was to investigate the effect of individual additions of mono- and divalent electrolytes (NaCl and CaCl2), anionic (sodium dodecyl sulfate, SDS) and non-ionic surfactants (polysorbate 80, Tween 80) at varied concentrations on the generation and stability of bulk nanobubbles (NBs) from carbon dioxide (CO2) gas in aqueo...

Bulk nanobubbles (NBs) are ultrafine gas-filled cavities at nanoscale size possessing unique properties which can provide promising benefits to food product quality and processability. This work aimed to investigate the formation and stability of CO2 bulk NBs in water for intended applications in food processing. The NBs were generated by injecting...

The effects of non-thermal plasma (NTP) using a gliding arc (GA) discharge was studied with harvested Nam Dok Mai mangoes to determine the rate of retardation of anthracnose disease (Colletotrichum gloeosporioides). Different fluxes of argon (Ar) gas (3–5 L/min) and treatment times (5–7 min) with NTP delayed mycelium growth as well as decreasing fu...

Nonthermal plasma (NTP) is defined in terms of partly ionised gas which overall temperature is quite low because the stored energy is mostly in free electrons. Applications of NTP have been expanded to new areas of food applications such as the microbial inactivation and also the elimination of pesticide and toxic chemical residues in food such as...

Mango is considered as a popular and economically important tropical fruit around the world because of its attractive color, favorable flavor, and high nutritional quality. Nowadays, more consumers consciously desire not only fresh and nutritious but also safe fruits with low or free of microorganisms and chemical contamination. Non-thermal plasma...

Supercritical carbon dioxide extraction of Gac (Momordica cochinchinensis Spreng) aril was performed at pressures ranging from 200 to 400 bar, temperatures from 313 to 343 K and specific flow rates from 50 to 90 kg•h-1 CO2 kg-1 Gac aril. Total oil recovery and carotenes concentration were investigated in the course of extraction. Mathematical model...
