“…The colour of the coated donuts was calculated by following eqs. (3)–(5) (Sumonsiri et al ., 2020; Murid et al ., 2022).

Whitening index = 100 - {(][, {(100 - L^{*})}^{2} goodbreak+ {(a^{*})}^{2} goodbreak+ {(b^{*})}^{2})}^{1 / 2}

Chroma = {(][, {(a^{*})}^{2} goodbreak+ {(b^{*})}^{2})}^{1 / 2}

Change in colour = {(][, {(L^{*} - L^{*} c)}^{2} goodbreak- ()(, a^{*} - a^{*} c) goodbreak+ ()(, b^{*} - b^{*} c))}^{1 / 2}

“…These coatings are applied through a tumble drum or on a conveyor system. These processes create expensive and difficult‐to‐clean‐up powder waste to achieve uniform coating (Rick et al ., 2002; Karasu & Ermis, 2019; Sumonsiri et al ., 2020). Besides, insufficient adhesion between spices and snack surfaces causes the flavour to be unevenly distributed.…”

“…This coating technique significantly lowers the quantity of powder waste and dust since the powders seek the target (Khan et al ., 2014; Likitwattanasade & Barringer, 2015). Due to improved coating consistency and lower powder waste and dust, the electrostatic coating is becoming more popular in the food industry (Sumonsiri et al ., 2020).…”

Donuts are the snack food which are coated with powdered seasonings to increase flavour and shelf life. In this regard, electrostatic coating is being developed for efficient coating method and to overcome uneven coating and dust production. During electrostatic coating, charged powder particles produce even coating on target surface. Electrostatic coating of cocoa powder was carried out at high voltage (0-20 kV) and the results were compared to manually coated fried donuts. Cocoa powder particles had irregular polygonal and polyhedral shapes with an average particle diameter (18.12 AE 0.91 μm). The values of adhesion, dust reduction and transfer efficiency were higher at 15 kV and lower values at 0 kV. Coated sample at 15 kV showed the lowest change in weight loss (05.99%) during the storage. Due to an even coating of cocoa powder at 15 kV, donuts exhibited pleasant taste, uniform and dark brown colour. While, shelf life of coated donuts at 15 kV lasts up to 29 days as compared to other samples. It can be concluded from the results that the electrostatic coating of donuts with cocoa powder was best at 15 kV with higher transfer efficiency, adhesion and consumer acceptability.
