为了探讨复热方式对里脊肉类预制菜品质的影响,以番茄里脊预制菜为研究对象,采用微波(高火、中火、低火)、水浴、蒸汽对菜肴包进行复热处理,测定产品的硫代巴比妥酸(TBA)值、剪切力、挥发性风味物质和滋味成分,并进行感官评价,结合主成分分析和聚类分析,评估复热方式对产品品质的影响。结果表明,复热方式对番茄里脊预制菜的TBA值、剪切力、滋味、挥发性风味物质和感官评分的影响显著(P<0.05)。蒸汽复热后产品具有较低的TBA值和适宜的剪切力,分别为0.69 mg/kg和1 681.67 g,番茄里脊预制菜特征性风味物质主要为(Z)-2-庚烯醛、十六醛、反-2-辛烯醛、反,反-2,4-癸二烯醛、芳樟醇、乙基麦芽酚、丁香酚、石竹烯、2-异丁基噻唑,蒸汽复热后挥发性风味物质在种类和数量上优于其他复热方式。水浴复热后滋味物质显著差异于其他复热方式,而微波复热和蒸汽复热后各滋味较平衡。结合感官评价,蒸汽复热后产品的气味和滋味更能让消费者接受,因此蒸汽复热相比其他复热方式对番茄里脊预制菜的品质具有明显的优势。 相似文献

为探究不同复热方式对油焖南美白对虾预制菜品质的影响规律,采用微波、蒸汽、水浴三种不同复热方式对冻藏油焖南美白对虾预制菜产品进行复热加工。通过测定复热后产品的水分含量、水分活度、质构、感官品质、游离氨基酸、呈味核苷酸、挥发性成分、微观结构等指标,综合确定最优复热方式。结果表明:相比于蒸汽和水浴复热,微波复热对产品品质影响最小,水分损失最小为4.00%,水分活度损失最小为1.00%,硬度增加最小为6.44%,咀嚼性增加最小为1.00%,弹性下降2.03%。从风味来看,微波复热组各风味得分与对照组最为接近;微波复热组游离氨基酸总量显著上升,提高了2.78%,蒸汽和水浴复热组游离氨基酸总量下降;微波、蒸汽、水浴复热分别检测出69、61、64种挥发性物质,其中微波复热组挥发性物质种类最多,醛类化合物相对含量最高为33.81%,高于蒸汽复热组29.89%及水浴复热组29.15%;微波复热组鲜味核苷酸IMP、AMP含量高于其他复热组,结合味精当量和滋味强度值可知,微波复热组产品具有更高的等鲜浓度。微波复热组产品的肌肉组织排列情况和纤维束光滑程度均优于其他两种复热方式。综合各项指标,微波复热是油焖南美白对虾预制菜产品较为理想的复热方式。 相似文献

为解决新零售预制烤鱼经冷冻复热后口感下降的问题,选取草鱼为研究对象,以水分含量、持水力、水分分布及组成和微观结构等为指标,探究鱼肉油炸、冷冻、复热不同阶段的品质变化规律。结果表明,随冻融循环次数增加,鱼肉肌纤维破坏程度增加,水分含量显著降低(P <0.05),持水性变差,脂肪氧化和蛋白降解程度显著增加(P <0.05),风味发生改变。复热后,冻融1次鱼肉仍能保持较好口感,但冻融2次后鱼肉感官评分较低,且肌原纤维小片化指数、TBARS和TCA-可溶性肽含量较冷冻前样品分别增加了24.44%、225.84%和52.85%。综上,当油炸预制鱼产品在贮运流通过程中发生冻融次数超过2次时明显降低产品食用品质和消费者接受度。 相似文献

随着现代生活节奏的加快和饮食习惯的转变,预制肉类食品因其便捷性和多样性而受到广大消费者的青睐。在预制肉类食品生产、销售及消费过程中,贮藏和复热是2个关键环节。阐述了预制肉类食品在贮藏和复热过程中的品质变化及其影响因素。在贮藏期间,预制肉类食品常因为多种因素导致品质劣变,例如持水性降低、质构特性下降、色泽劣变、脂肪和蛋白质的氧化等。这些变化不仅影响食品的口感和营养价值,还可能会引发食品安全问题,进而减少消费者的购买意愿。在预制肉类食品复热过程中,不同复热方式对预制肉类食品的品质产生不同的影响。传统的蒸煮、烤制和油炸复热方式虽然使用广泛,但可能导致风味和质地的下降,而微波复热则能更快速、均匀地加热,尽管微波复热也可能引起某些品质的下降。提出了提升品质的策略,包括添加天然抗氧化剂、升级包装技术、采用新型杀菌和辅助冷冻技术等,旨在推进预制肉类食品行业的创新和可持续发展。 相似文献

为研究不同热杀菌条件对蒸排骨预制菜品质的影响,以猪肋排为原料,对比分析相同杀菌强度下不同杀菌条件(115℃/36 min、121℃/14 min、127℃/7 min)处理的蒸排骨预制菜的食用品质和营养品质。结果表明,杀菌强度为5 min时,随着杀菌温度的提高,烹饪值(cook value,C)不断降低,排骨肉色泽略有劣变,但嫩度和质地有所提升;营养损失率降低,其中127℃组的必需氨基酸总含量显著高于115℃组和121℃组(P<0.05),为9.73 g/100 g;总挥发性盐基氮(total volatile basic nitrogen, TVB-N)含量从115℃时的8.66 mg/100 g显著下降到127℃时的7.36 mg/100 g(P<0.05)。电子鼻主成分分析可以反映不同杀菌条件下挥发性气味上的差异,随着杀菌时间的延长,排骨中甲基类、硫化物、醇类和醛酮类等风味物质的响应值不断增大。总体而言,适当提高杀菌温度、缩短杀菌时间,更有利于蒸排骨预制菜质地、营养品质的保留。 相似文献

BackgroundThermal pasteurization and sterilization are predominantly used in the dairy industry due to their efficacy in improving the product safety and shelf life. However, heat treatment can cause undesirable protein denaturation, non-enzymatic browning, loss of vitamins and volatile flavor compounds, freezing point depression, and flavour changes. Cold plasma is a non-thermal technology that has gained attention in recent years as a potential alternative method for chemical and thermal disinfection in foods using ambient or moderate temperatures and short treatment times.Scope and approachThis review aims to describe the fundamentals, parameters, and technology on cold plasma, discussing the critical processing factors involved in this technology. Also, it describes the mechanisms of microbial inactivation and provides an overview of the effects of non-thermal plasma on the quality of dairy products, considering a physicochemical, sensory and microbiology perspective.Key findings and conclusionsCold plasma uses less aggressive mechanisms of action to the milk matrix when compared to the techniques currently used, and has shown an excellent performance on the elimination of pathogenic and spoilage microorganisms besides maintaining, in many cases, the nutritional, functional, and sensory characteristics of the product. 相似文献

Folate content and retention were evaluated in 10 different precooked vegetarian ready meals before and after reheating. Folate was quantified using a validated high-performance liquid chromatography method. The only form of folate found was 5-methyltetrahydrofolate. Folate content in thawed ready meals varied from 23 to 81 μg/portion (400 g) on fresh weight basis. Products served with couscous and potatoes contained more folate than products served with rice. Folate retention during reheating was investigated in the microwave oven (900 W/5.5 min), in a saucepan on stove until the food reached 85 °C, and in oven (225 °C/40 min). The true vitamin retention varied for the three investigated portions as follows: on stove (63-93%), microwaving (55-89%) and in oven (50-92%). Our results indicate that folate content in the ready meals prior to reheating, contributed to 6-27% of the recommended intake (300 or 400 μg folate per day). After reheating folate content was significantly (P<0.05) reduced in some meals but were kept constant in others and folate content was reduced to 3-25% of the recommended value. No clear pattern in folate retention between different heating methods was seen. However, the meals with ingredients suggesting high concentrations of antioxidants were less prone to loose folate when heated since the antioxidants probably protected the folates. 相似文献

Technology options for new nutritional concepts 总被引:3,自引:0,他引:3
Hannu Korhonen 《International Journal of Dairy Technology》2002,55(2):79-88
Recent advances in the food and nutrition sciences support the concept that the diet has a significant role in the modulation of various functions in the body. The diet and/or its components may contribute to an improved state of well-being, a reduction of risks related to certain diseases and even an improvement in the quality of life. These new concepts have led to the introduction of a new category of health-promoting foodstuffs, i.e. functional foods.
The concern about health embraces a number of driving issues, needs and opportunities which may be approached by designing specific diets from various food raw materials. These tailor-made products provide physiological benefits that are targeted at particular consumer groups.
The functionality of functional foods is based on bioactive components, which may be contained naturally in the product but usually require formulation by appropriate technologies in order to optimise the desired beneficial properties. To this end, it is often necessary to develop and apply novel technologies, e.g. membrane separation, high hydrostatic pressure and supercritical fluid extraction techniques. Also the minimal processing concept could be employed in this context.
This review discusses the current technological options available and the future challenges faced in the area. Particular attention is paid to the exploitation of bovine colostrum and milk-derived bioactive compounds for the development of functional foods. 相似文献
