The Possibility of Edible Coating Applications on Apple Pieces: Case Study with Colour Changes

Simona Jancikova

The aim of the study was to monitor color changes of apple pieces after application of different coatings. The material for the study were Granny Smith apples (bought in retail shop: Tesco s.r.o.).

 The experimentally produced coatings consisted out of distilled water, pectin and hemp flour extract (HFE). The samples were following: CONTROL (without packaging), PHFE1 (1% pectin and 5% HFE), PHFE3 (3% pectin and HFE) and PHFE5 (5% pectin and 5% HFE). Pectin and hemp flour were bought from retail shops Gresik and DM drogerie, respectively.

The color measuring was done by personal camera EOS600D (Canon, JPN). The sample scanning was completed under standard light conditions with 2 lamps Delux L – 1 x 18 W lamps (OSRAM, GER). The shooting was done by the manual: exposure time 1/80, aperture F 5.0, image size L, sensitivity ISO 100.
