Effects of different duck meat and wheat bran contents on the quality characteristics of sausages

Purpose – This paper aims to evaluate the effect of different fiber sources and tert-butylhydroquinone (TBHQ) on the quality characteristics of chicken harrisa. Design/methodology/approach – An attempt was made to develop fiber-enriched chicken harrisa, a meat-based product, by incorporating optimum level of different fiber sources, viz., oat bran (10 per cent) or wheat bran (10 per cent) or barley bran (5 per cent). The products developed with optimized level of fiber were further treated with TBHQ (200 ppm) and were aerobically packaged in low-density polyethylene pouches along with control and assessed for various storage quality parameters under refrigerated (4 ± 1°C) conditions. The products were evaluated for various physicochemical, microbiological and sensory parameters at regular intervals of 0, 7, 14 and 21 days. Findings – A significant (p < 0.05) increase was observed in the fiber content of the products prepared with oat bran (10 per cent) or wheat bran (10 per cent) or barley bran (5 per cent). TBHQ showed a significant (p < 0.05) effect on the lipid oxidative stability, as the treated products exhibited significantly (p < 0.05) lower thiobarbituric acid-reactive substance (mg malonaldehyde/kg) values for the entire period of storage. No significant (p > 0.05) effect was observed on the microbiological characteristics of the products. Sensory parameters showed significant (p < 0.05) decreasing trend for control as well as TBHQ-treated products throughout the period of storage; however, significantly (p < 0.05) higher scores were observed for treated products in comparison to control. Originality/value – Fiber-enriched chicken harrisa was developed by incorporating oat bran (10 per cent) or wheat bran (10 per cent) or barley bran (5 per cent) in the formulation. TBHQ successfully improved the lipid oxidative stability and storage quality of fiber-enriched chicken harrisa during refrigerated (4 ± 1°C) storage and may be commercially exploited to improve the storage quality of the product.

This study was conducted to evaluate the efficiency of the substrate on the productivity and quality for Flammulina velutipes. Results of the effect of different agro-waste sawdust (SD), wheat straw (WS) and palm waste (PW). on the mean fungal mycelium growth shows that Flammulina velutipes gave the highest mean fungal mycelium growth on SD culture media amended with 2, 3, 4% lime at 30c. evaluation the efficiency of the above agro-waste substrate morphological and productivity showed that, the shortest period for the full growth of F. velutipes mycelium was on SD substrate, the shortest period for the pinhead formation 8.6days on the fungus gave highest yield on WS which was 152.3 gm/ bag with 61.1% biological efficiency. The shortest time for full growth of F. velutipes was achieved in PW amended with wheat bran, the highest yield was in WS enriched with wheat bran which 306.7 gm/ bag with 129.3% biological efficiency. Results showed differences in quality characteristics in fruit bodies of fungi by effect of substrate.
