Active biodegradable film with encapsulated anthocyanins: Effect on the quality attributes of extra-virgin olive oil during storage

Abstract

The aim of this study was to verify the effectiveness of an active biodegradable film on the maintenance of extra‐virgin olive oil (EVOO) quality attributes. Level of peroxides, acidity, K232, color, chlorophylls, and carotenoids were determined as parameters to verify the oil quality over storage period. Maltodextrin was used to encapsulate anthocyanins and was the major component in the films, which were used as pouches to pack the oil. The samples were stored at 40°C, exposed to fluorescent light, and monitored during 12 days. The film successfully maintained the quality of EVOO under the limits established by Codex Alimentarius for over 8 days (13.6 meq O2/kg of peroxides at the 8th day), while the oil packed in polypropylene pouches was degraded before the 4th day of storage (326.5 meq O2/kg). Therefore, the results demonstrated the effectiveness of the film on maintaining the quality of EVOO and its promising application as active packaging. Practical application Extra‐virgin olive oil (EVOO) is an oxidation‐sensitive product and has been shown to quickly deteriorate when stored under less than ideal conditions. The study brings a new packaging possibility to the commercialization of EVOO with longer shelf‐life. The storage of extra‐virgin olive oil in biodegradable pouches produced with anthocyanins could preserve EVOO from oxidation and consequently extent its shelf‐life. The study proves the efficacy of an active biodegradable packaging on maintaining quality attributes of EVOO. The commercialization of EVOO in active biodegradable pouches could be an eco‐friendly and sustainable way to bring health and practicality to consumers.

Gelatin capsule residue‐based films crosslinked with the natural agent genipin

“…The primary oxidation of sunflower oil was retarded by GCR‐based films in comparison with oil packed in transparent polyethylene terephthalate (PET) bottles and unpacked, as assayed by peroxide value during 28‐35 days under accelerated conditions . Starch‐based film incorporated with encapsulated anthocyanins were effective on protecting EVOO from oxidation under accelerated conditions . It was found that the biodegradable films maintained PV values under the limit up to Day 8 (13.6 mEq/kg), whereas EVOO packed in PP was deteriorated before Day 4 (326.5 mEq/kg).…”

“…The effect of GCR‐GEN films on maintaining the quality attributes of EVOO under accelerated storage conditions was investigated following the methodology described by Stoll et al with some modifications. Films were produced to develop EVOO sachets designed for single use.…”

“…The decreased values of b* values corresponded to the shift from yellow to blue and are related to the degradation of carotenoids. 36 Therefore, ML and GCR-GEN films were able to maintain the organoleptic aspect of EVOO and protect it from the degradation of chlorophylls and carotenoids.…”
