Development and evaluation of hinokitiol active paper sheets for the postharvest management of broccoli

Active paper sheets are one of the upcoming technologies in the active packaging area for the shelf-life extension of fruits and vegetables.
Active paper sheets release active volatile compounds into the system during the storage and help to extend shelf life and prevent microbial spoilage while maintaining quality attributes.
Hinokitiol or β-thujaplicin is a tropolone derivative found in several plants of the Cupressaceae family.
It has been reported as an antimicrobial, antiviral, anti-tumour, anti-ischaemic, antiproliferative and chelating agent.
The volatile form of hinokitiol is reported to be more effective in scavenging ethylene and inhibition of postharvest pathogens.
Broccoli (Brassica oleracea L. var. italica) loses quality rapidly if not maintained properly.
The present study focuses on the development of active paper sheets using hinokitiol.
The hinokitiol release rate from the active paper sheets was measured at different temperature ranges (10-30°C) to simulate the storage conditions of broccoli.
The standardized active paper sheets were incorporated along with broccoli and stored at 5 and 20°C for 15 and 5 days, respectively.
The quality attributes like colour, loss in mass, pigment composition, sugars, and vitamin C (L-ascorbic acid and dehydroascorbic acid) were studied during storage.
