概括
干燥老化 (DA) 比湿燥老化 (WA) 提高了被杀的羊肉质量,提高了水容量并减少了损失. 然而,最佳的感官属性是在干燥老化后的14天内实现的.
科学领域:
- 食品科学 食品科学 食品科学
- 肉类科学 肉科学
- 动物科学动物科学
背景情况:
- 切割的羊肉往往在质地和感官吸引力方面提出了挑战.
- 老化是改善肉质属性的关键过程.
- 了解不同老化方法 (湿或干) 的影响对于优化肉类加工至关重要.
研究的目的:
- 为了比较湿老化 (WA) 和干老化 (DA) 对35天内被杀的母羊肉的影响.
- 为了评估衰老过程中的物理化学,色度,氧化,伏拉托洛米和感官变化.
- 为了确定干燥年龄的屠宰羊母羊肉的最佳老化期.
主要方法:
- 来自被屠杀的母羊的肉类经过湿 (WA) 和干 (DA) 长达35天.
- 进行了物理化学 (水容量,损耗),色度,氧化和伏拉托洛米 (化物,) 分析.
- 感官评估,包括整体喜欢分数,在不同的时间点进行.
主要成果:
- 与湿 (WA) 肉相比,干 (DA) 肉的容量增加,损失减少.
- 华纳布拉茨勒切削力在DA肉中增加,但在WA肉中减少.
- 氧化产物,特别是和,在DA肉中较高,达到早期峰值.
- 感官喜好分数在14日和21日偏爱DA肉,但在35日下降.
结论:
- 干燥老化可以提高被屠宰的母羊肉的可接受性,而不是湿老化,特别是在短时间 (14天) 的老化期内.
- 延长干燥老化超过14天可能会导致由于氧化增加而导致不良的感官变化.
- 进一步研究控制干燥老化过程中的氧化,可以最大限度地提高被杀的羊肉的益处.

The Effect of Aging on Tissues
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...
Pasteurization and Food Preservation
Pasteurization is a widely employed thermal processing technique designed to enhance the safety and shelf life of perishable food and beverages. By subjecting products to specific high temperatures for controlled durations, this method effectively inactivates pathogenic microorganisms and spoilage enzymes without significantly compromising sensory qualities. The technique has been pivotal in food safety management, especially for consumables susceptible to microbial contamination such as milk,...
Principles of Food Preservation
Food spoilage results from microbial growth, enzymatic activity, and environmental factors that gradually degrade the sensory, nutritional, and safety qualities of food. Preservation techniques aim to slow or halt these processes to extend shelf life and maintain product quality.A key concept in food microbiology is the microbial growth curve, which includes four phases: lag, exponential (log), stationary, and death. During the lag phase, bacteria adjust to their environment without significant...
Methods of Controlling Food Spoilage
Food spoilage is caused by microbial growth or by chemical and physical changes, all of which affect the taste, texture, and safety of food.Temperature-Based PreservationRefrigeration at 0–4 °C slows microbial growth and enzyme activity, making it ideal for short-term storage. However, certain spoilage organisms—such as psychrotrophs like Listeria monocytogenes—can still proliferate at these temperatures. Freezing below -18 °C further slows biological processes by forming ice crystals, which...
