Use of Nanoclay-Containing Lid Packaging Film in Lavender Essential Oil Packaging

Abstract

In this study, an environmentally friendly nanoclay-containing polymeric film (NPF) that can be used instead of environmentally damaging plastic lids used in food packaging was produced and its effect on the shelf life of lavender essential oil was examined by using it as a lid packaging film in the packaging of lavender essential oil. For this purpose, lavender essential oil was covered with nanoclay-containing polymeric films and physicochemical analyzes were carried out in the control group, 2nd month, 4th month and 6th month. SEM analysis was applied to the produced nanoclay, and biodegradability, haze and FTIR analyzes were applied to the produced film. Then, acidity, peroxide, color, refractive index, viscosity and essential oil components analyzes were applied to the stored essential oil at specified intervals for 6 months. As a result of these analyses, it was seen that the film showed a 31.74% deterioration in nature in the 6-month period, and the haze analysis result was determined as 87.17%. Acidity value (0.38%-0.68%), peroxide number (3.46-9.06), color results of lavender essential oil during storage *L (40.63-67.86), *a (–0.89/-1.56), *b (3.92- 5.23), refractive index results (1.4578-1.4632) viscosity results (2.78-6.87 mPa) and dominant essential oil components linalyl acetate (27.04%-31.74%) and linalool ­(42.80%-46.6%), lavandulyl acetate (1.25%-1.35%), 1-8 cineole (3.44%-4.29%), camphor (4.07%-5.26%) and borneol (2.18%-2.89%). In line with these results; It has been determined that the nanoclay-containing polymeric films produced as lid packaging have as much protective effect as the plastic lid.
