包材对常温奶感官及风味品质的影响研究

引言：常温奶是一种方便易用的乳制品，消费者可随时享用。然而，包材作为常温奶的外部环境，可能会对奶的感官特性和品质产生影响。因此，本研究旨在探究常温奶包材对其感官特性和风味品质的影响。

方法：我们选取了常见的常温奶包材，包括塑料瓶、纸盒和铝罐，并运用相关科学方法进行了测试和分析。首先，我们对不同包材的外观进行了比较，探究了它们的透明度、光泽度和包装密封性。然后，我们通过感官评估，对常温奶的颜色、气味、口感和口感持久度进行了评价。最后，我们使用电子鼻和电子舌等现代化仪器，对常温奶的风味进行了定量分析。

结果：我们的研究发现，不同的常温奶包材对其感官特性和风味品质有显著影响。外观方面，塑料瓶具有良好的透明度和光泽度，但其密封性稍逊于纸盒和铝罐。感官评估结果显示，纸盒包装的常温奶在颜色、气味和口感方面得分较高，而塑料瓶包装的常温奶则在口感持久度方面得分较高。风味分析结果显示，塑料瓶包装的常温奶在酸度和奶香风味方面较为突出，而纸盒包装的常温奶在甜度和奶油风味方面表现较好。

讨论：包材对常温奶的影响主要涉及其外观、感官特性和风味品质。不同包材的特点和优劣势决定了其对常温奶品质的影响。塑料瓶虽然外观透明度高，但其密封性稍逊，可能导致氧气和外界异味的渗透。纸盒具有较好的密封性和透气性，可保持常温奶的新鲜度和风味特性。铝罐则具有良好的阻隔性，能够有效防止氧气、光线和异味对奶品质的影响。

结论：本研究表明，常温奶的包材对其感官特性和风味品

质具有显著影响。纸盒包装的常温奶在外观、感官和风味方面表现较为优秀，成为当前常温奶包装的主要选择。然而，未来在包材的研发中，需要解决塑料瓶密封性的问题，并进一步优化铝罐的透气性和包装设计，以提升常温奶的品质和消费者的满意度。

Effects of Packaging Materials on Sensory and Flavor Quality of Shelf-Stable Milk

Introduction: Shelf-stable milk is a convenient and easy-to-use dairy product that consumers can enjoy at any time. However, the packaging materials, as the external environment for shelf-stable milk, may have an impact on the sensory characteristics and quality of the milk. Therefore, this study aims to investigate the effects of packaging materials on the sensory characteristics and flavor quality of shelf-stable milk.

Methods: We selected common packaging materials

for shelf-stable milk, including plastic bottles, paper cartons, and aluminum cans, and conducted tests and analysis using relevant scientific methods. Firstly, we compared the appearance of different packaging materials, exploring their transparency, glossiness, and packaging sealing. Then, we conducted sensory evaluation to assess the color, smell, taste, and persistence of shelf-stable milk. Finally, we quantitatively analyzed the flavor of shelf-stable

milk using modern instruments such as an electronic nose and electronic tongue.

Results: Our study found that different packaging materials for shelf-stable milk have a significant impact on its sensory characteristics and flavor quality. In terms of appearance, plastic bottles have good transparency and glossiness, but their sealing is slightly weaker compared to paper cartons and aluminum cans. Sensory evaluation results showed that shelf-stable milk packaged in paper cartons scored higher in terms of color, smell, and taste, while shelf-stable milk in plastic bottles scored higher in terms of taste persistence. Flavor analysis showed that shelf-stable milk in plastic bottles stood out in terms of acidity and milky flavor, while milk in paper cartons performed better in terms of sweetness and creamy flavor.

Discussion: The impact of packaging materials on shelf-stable milk mainly involves appearance, sensory characteristics, and flavor quality. The characteristics and advantages and disadvantages of different packaging materials determine their impact on the quality of shelf-stable milk. Although plastic bottles have high transparency, their sealing is slightly weaker, which may result in the permeation of oxygen and external odors. Paper cartons have good sealing and air-permeability, which can maintain the
