Effect of essential oils incorporated edible film on quality and storage stability of chicken patties at refrigeration temperature (4 ± 1 °C).

A blend of oregano and thyme essential oils (EOs) incorporated edible film was evaluated to improve the storage quality of chicken meat patties. Several preliminary trials were carried out to optimize the levels of bio-polymer to obtained desired edible film as a carrier and blend of EOs as bio preservatives. Preliminary studies indicated that 1.5% (w/v) solution of carrageenan as bio-polymer and 0.10% (v/v) oregano with 0.15% (v/v) thyme EOs in blend form as antimicrobial were suitable. Chicken meat patties wrapped with edible film incorporated with aforementioned EOs, packaged aerobically were stored at refrigeration temperature (4 ± 1 °C) for further studies. Results of refrigeration storage, showed that control samples had significantly higher pH and thiobarbituric acid reacting substances value than EOs treated products. There were significantly lower microbial counts observed in treatment samples (with EOs) and found well within permissible limit as compared to control. All the treatment samples showed lower or comparable flavour score in regard with control. It was found that shelf-life of chicken meat patties increased significantly (P < 0.05) during refrigerated storage and showed acceptable quality up to storage period of 30 days.

Quality of ω-3 fatty acid enriched low-fat chicken meat patties incorporated with selected levels of linseed flour/oil and canola flour/oil.

The aim of the present study was to compare the nutritional, processing and sensory characteristics of low-fat ω-3 enriched fatty acids chicken meat patties (CMP) prepared with the incorporation of 4% linseed flour (T1), 2% canola flour (T2), 3% linseed oil (T3), and 4% canola oil (T4) and to estimate their cost of production. The total fat and crude fiber content was increased (P < 0.05) with the incorporation of linseed flour. The emulsion stability and cooking yield was greater (P < 0.05) in T4 among all the treatments. The percent shrinkage was lower (P < 0.05) in linseed/canola oil incorporated CMP than their respective flours. The colour and appearance and flavour scores were lower (P < 0.05) in canola flour than canola oil incorporated CMP. The texture scores were not influenced (P < 0.05) in linseed-and canola-treated products. The overall acceptability was greatest (P < 0.05) in T4 whereas, lowest (P < 0.05) in T2 among all treated products. The cost of production was increased by 3-5% with the incorporation of linseed and canola oil whereas it was almost same for control and linseed flour.

Development of dietary fiber rich chicken meat patties using wheat and oat bran.

Dietary fiber rich chicken meat patties were developed by incorporating wheat and oat bran to chicken meat at 5, 10 and 15% levels. Oat bran contained higher amount of soluble dietary fiber (SDF) and unsaturated fatty acids (USFA) than wheat bran, whereas total dietary fiber (TDF), insoluble dietary fiber (IDF) and saturated fatty acids (SFA) were higher in wheat bran. Incorporation of bran significantly increased the water holding capacity (WHC) and emulsion stability (ES). Oat bran showed better effect on WHC and ES than wheat bran. Addition of bran resulted in significant increase in cooking yield, firmness, TDF, USFA and reduction in sensory attributes, moisture, protein, fat and cholesterol content. IDF was higher in wheat bran added patties and SDF and SFA/USFA ratio in oat bran added patties. It is concluded that oat and wheat bran can be incorporated up to 10 and 15% level, respectively for preparation of baked and steamed chicken patties.
