The present study provides a comprehensive evaluation of carcass traits and meat quality characteristics of the Eurasian collared dove (Streptopelia decaocto), with particular emphasis on the effects of sex and muscle type on meat quality. A total of 40 adult birds (20 males and 20 females) were analysed for carcass traits, proximate composition, amino acid profile, fatty acid composition, lipid quality indices and colour characteristics. Carcass yield averaged approximately 67% and did not differ significantly between sexes (P > 0.05). Breast muscle was characterised by a high protein content [male 24.32; female 24.36 g·(100 g)–1]...

Konjac glucomannan (KGM), derived from konjac tubers, is a novel functional plant polysaccharide that plays a significant role in antioxidant activity, anti-tumour effects and blood glucose regulation. This study aimed to develop an optimal extraction method for KGM. The extraction yield of KGM was surveyed quantitatively analysed using a response surface central composite design (CCD) to maximise the yield. A quadratic regression model was created to illustrate the interactions between the factors influencing KGM extraction yield. The findings indicated that the effects of extraction temperature and the liquid-to-solid ratio had a greater impact on...
