肉制品在热加工后需要进行快速冷却,以避免熟肉中微生物繁殖及保证品质。然而,传统的冷却方法难以满足这一要求,尤其是肉制品核心温度的降低。真空冷却技术的冷却速度快且冷却均匀,可快速降低熟肉制品的温度,进而延长产品的货架期和贮藏期等。但与此同时也带来了一些问题,如失重率高、投入成本较高等。真空冷却技术作为具有独特发展潜力的食品快速冷却技术,其特有的优势促使了人们对其的深入研究。为促进真空冷却技术的发展,本文综述了肉制品真空冷却技术的研究进展。 相似文献

To optimise vacuum cooling for application in the meat industry, an improved cooling method, i.e. vacuum cooling with water (or immersion vacuum cooling), was designed to cool cooked pork ham (2.2 ± 0.2 kg). It was found that the cooling time of vacuum cooling with water was significantly shorter than that of traditional air blast cooling (P < 0.05). For the cooling loss, vacuum cooling with water was significantly lower (6.99%) than that of vacuum cooling without water (13.71%) (P < 0.05). Significant differences in physical and chemical attributes were also observed for ham processed by vacuum cooling with and without water (P < 0.05). Therefore, for a certain size of pork ham, vacuum cooling with water could be an effective method to meet safety guidelines and obtain compatible quality attributes with air blast cooling. 相似文献

In this paper, immersion vacuum cooling with ultrasonic assistance (IVCUA) is compared with immersion vacuum cooling alone (IVC) and vacuum cooling (VC) for cooling time, mass loss, colour, texture profile and water mobility and compartmentalization for cooked meat products. The results reveal that IVCUA clearly enhances the boiling intensity of impregnation liquid compared to IVC. The total cooling time using IVC (126.56 min) for samples from 72 to 4 °C was significantly longer (P < 0.05) than that of IVCUA (96.89 min) and VC (80.48 min). The cooling time of samples from 10 to 4 °C by IVC (46.26 min) was higher (P < 0.05) than that by IVCUA (28.55 min). There were no significant differences (P > 0.05) in mass loss, colour and texture profile among all samples. However, IVCUA had a higher transverse relation time of bulk water (T24) and MRI proton densities (P < 0.05), as well as a more uniform water distribution compared to IVC. 相似文献

In order to achieve a rapid cooling rate and to increase the industrial yield of the products without compromising their quality attributes, immersion vacuum‐cooling (IVC) is now widely applied for cooling of both small and large food items. However, the lower cooling rate compared with vacuum‐cooling has initiated numerous studies to improve this technique. Substantial efforts, such as combination of IVC with other cooling methods, using different initial water temperatures, or employment of agitation during IVC, have been made to optimize cooling parameters while also maintaining quality properties and complying with strict food safety requirements. This review presents and discusses the IVC evolution and recent developments directed at the ready‐to‐eat meat products industry. The principle of IVC and its applications are discussed first. Then future prospects and suggestions are covered, especially for the cooling of ready‐to‐eat meat products. 相似文献

粽子在蒸煮后需冷却。为了寻找合适的冷却方法,通过真空冷却、冷风冷却、自然冷却3种方式处理煮后的3种速冻粽子,测定这些粽子的品质差异。结果表明:与常规冷却方式相比较,真空冷却速率高(P0.05),冷却损失较高(P0.05)。质构分析表明:真空冷却产品硬度较大(P0.05),而黏着性、弹性、内聚性、胶黏性、咀嚼性和回复性方面没有显著差异(P0.05)。感官分析表明:真空冷却的产品口感虽然不及常规冷却的产品,但在可接受的范围。化学指标分析表明,真空冷却能显著降低菌落总数。电子鼻分析结果表明:豆沙粽子和肉粽子真空冷却与常规冷却的产品挥发性气味显著不同,而对白粽子的影响不显著。真空冷却是一种快速、安全的冷却方法。 相似文献

Vacuum cooling (VC) is commonly applied for cooling of several foodstuffs, to provide exceptionally rapid cooling rates with low energy consumption and resulting in high-quality food products. However, for products such as meat and cooked meat products, the higher cooling loss of vacuum cooling compared with established methods still means lower yields, and important meat quality parameters can be negatively affected. Substantial efforts during the past ten years have aimed to improve the technology in order to offer the meat industry, especially the cooked meat industry, optimized production in terms of safety regulations and guidelines, as well as meat quality. This review presents and discusses recent VC developments directed to the cooked meat industry. The principles of VC, and the basis for improvements of this technology, are firstly discussed; future prospects for research and development in this area are later explored, particularly in relation to cooling of cooked meat and meat products. 相似文献
