Abstract

This study investigated the influence of ultrasound combined with slightly acidic electrolyzed water thawing (UST) on the rheological characteristics, quality and structure of mutton myofibrillar protein (MP) gel in comparison with other thawing methods (air thawing (AT), water immersion thawing (WT), microwave thawing (MT)). According to the result of rheological properties, the UST group had a higher storage modulus among thawing groups. UST treatment significantly improved the gel water holding capacity and whiteness (P < 0.05). In terms of texture, the MP gel of the UST group had better elasticity and strength than other thawing groups (P < 0.05). The UST treatment has no influence on the water distribution in the MP gel (P > 0.05). The UST treatment protected the secondary structure in the MP gel. Among all thawing groups, the UST group exhibited a smoother and more compact microstructure. In conclusion, the UST method effectively improved the MP rheological properties and gel quality, which could be applied as a promising method for deep processing of meat products.

期刊介绍: The aim of Meat Science is to serve as a suitable platform for the dissemination of interdisciplinary and international knowledge on all factors influencing the properties of meat. While the journal primarily focuses on the flesh of mammals, contributions related to poultry will be considered if they enhance the overall understanding of the relationship between muscle nature and meat quality post mortem. Additionally, papers on large birds (e.g., emus, ostriches) as well as wild-captured mammals and crocodiles will be welcomed.
