​Evaluation of Essential Oils as a Hurdle for Ambient Temperature Storage of Chicken Patties

Abstract

Background: Clove bud oil (CBO) and oleoresin rosemary (ORM) possess antioxidant and antibacterial properties and are widely used as natural preservatives in meat products. The present study was conducted with the objective of evaluating the essential oils CBO and ORM as a hurdle for extending the shelf life of chicken patties at ambient temperature storage. Methods: The natural preservatives viz. CBO at 0.05% level (T1) and ORM at 0.1% level (T2) and their combination (CBO 0.05% with ORM 0.1%) (T3) were incorporated in chicken meat patties in the basic formulation along with a control (C) and the cooked product quality packed in food grade pet-poly co-extruded film pouches stored at ambient temperature (30±2°C) was assessed. Result: Upon storage, in terms of sensory evaluation, T3 spoiled on 5th day and other samples on 3rd day of storage. Addition of essential oils significantly (P less than 0.05) enhanced the DPPH scavenging effect. TBARS and tyrosine values of all treatments significantly (P less than 0.05) increased linearly with storage period. CBO and ORM combination significantly (P less than 0.05) inhibited the microbial load during the storage period and maintained the odour score in the acceptable level even at 3rd day of storage. The combination of CBO and ORM might be applied as one of the hurdles in adopting the ‘Hurdle Technology’ storage of chicken meat patties.
