Spent Japanese quail (SJQ) meat was tenderized with ginger extract and utilized in the preparation of tandoori. The ginger extract level for tenderization of SJQ meat was optimized by physico-chemical and sensory analyses. The SJQ meat was treated with two levels of ginger extract and used for tandoori preparation along with two controls (broiler quail meat and spent quail meat). Japanese quail tandoori was prepared as four treatments namely CYB (Control young broiler), CSA (Control spent adult), G20 (Spent adult - ginger treatment 20%) and G40 (Spent adult - ginger treatment 40%). The aqueous ginger extract was prepared from fresh ginger rhizome (Zingiber officinale Roscoe). The SJQ was marinated in ginger extract marinade, tumbled, and placed in the chiller (4±1⁰C) for 24 hours and utilized for tandoori preparation. The cooked tandoori of all the treatments were analysed for the physico-chemical and sensory parameters. With ginger extract marination, the pH of cooked tandoori was not affected and the product yield was improved. In the organoleptic evaluation, the appearance score increased in the treatment with 20% ginger extract. The flavour score was significantly (p<0.05) higher in CYB and G20. The SJQ was significantly (p<0.05) tenderized by treatment with 20% and 40% ginger extract. CYB and G20 had significantly (p<0.01) higher scores for overall acceptability scores. It is concluded that 20% ginger extract level could effectively be used to tenderize the SJQ meat for the preparation of tandoori without affecting the physico-chemical and sensory properties.

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.
