Abstract

Objective: The aim of this study is to characterize the impact of additional electrical stimulation (AES) and various pre-rigor holding temperatures (for 3 h) on the ageing-potential of hot boned bovine M. longissimus lumborum (LL).

Methods: Paired LL loins from 12 bulls were hot-boned within 40 min of slaughter, immediate AES applied and subjected to various holding temperatures (5°C, 15°C, 25°C, and 35°C) for 3 h.

Results: AES did not accelerate the rate of rigor attainment, but the 3 h pre-rigor holding temperature did. Shear force values decreased as the pre-rigor holding temperatures increased. AES and holding for 3 h (at 25°C) resulted in higher water-holding capacity.

Conclusion: Data confirmed that AES did not influence the various meat quality parameters in the present study, but pre-rigor holding temperature (25°C) alone or in combination with AES resulted in superior meat quality.

额外电刺激和预严格调节温度对热骨牛肌肉老化潜力的影响。

目的:本研究的目的是表征额外电刺激(AES)和不同的预严格保温温度(3小时)对热骨牛腰最长肌(LL)老化电位的影响。方法:在屠宰后40分钟内，对12头公牛的腰肉进行热剔，立即应用AES并进行不同温度(5°C, 15°C, 25°C和35°C)保温3小时。结果:AES没有加速达到严格性的速度，但3小时前的严格性保温温度有。剪切力值随着预保温温度的升高而降低。AES和保温3小时(在25°C下)可以提高保水能力。结论:数据证实，AES在本研究中对肉质各项参数没有影响，但单独或联合采用25°C的预严格保温温度可以获得更好的肉质。

期刊介绍： Asian-Australasian Journal of Animal Sciences (AJAS) aims to publish original and cutting-edge research results and reviews on animal-related aspects of the life sciences. Emphasis will be placed on studies involving farm animals such as cattle, buffaloes, sheep, goats, pigs, horses, and poultry. Studies for the improvement of human health using animal models may also be publishable. AJAS will encompass all areas of animal production and fundamental aspects of animal sciences: breeding and genetics, reproduction and physiology, nutrition, meat and milk science, biotechnology, behavior, welfare, health, and livestock farming systems.
