Coagulation process in Manchega sheep milk from Spain: A path analysis approach

Characteristics of sheep milk are of great interest for the dairy industry, as almost the totality of production is intended for cheesemaking. However, the existing relationships between these variables are complex. This study assessed composition, hygienic quality, coagulation properties, and curd yield of 1,200 individual Manchega sheep milk samples. The aim was to compare the effect of composition and hygienic quality on coagulation and curdling, and to evaluate the relationship between curd yields and the coagulation process and the effect of other features by using path analysis methodologies. Outcomes proved path analysis to be a useful and effective tool to assess these relationships through direct and indirect paths within the same model. Results showed that the factors that had a direct influence on milk coagulation were lactose concentration, casein content, and initial pH of milk. Contrastingly, somatic cells did not seem to have any effect (direct or indirect) on the coagulation process. Factors that directly affected curd yield were fat content, lactose concentration, casein content, and curd moisture. However, technological parameters showed little effect over curd yield.     

预包装快餐食品营养标签的制作

按照《食品安全国家标准预包装食品标签通则》及《食品营养标签管理规范》的要求测定了19种预包装快餐食品的4种核心营养成分(蛋白质、脂肪、碳水化合物、钠)及能量,并设计营养标签。快餐食品标示营养标签势在必行,可使消费者根据自身营养需求选择合适的食物,也可规范餐饮业生产行为,生产出健康、营养的美食。     

模糊计划评审法在设备维修管理中的应用

设备维修是工业企业一项复杂的工作,设备维修的管理对减少维修周期、节省企业费用具有重要意义。传统的设备维修管理是基于计划评审法来组织维修活动,然而设备维修过程的每项活动时间具有模糊性。本文将模糊的概念引入到设备维修管理中,应用模糊计划评审法来组织和管理维修活动。

东台吉乃尔盐湖夏季卤水变温蒸发实验研究

针对柴达木盆地东台吉乃尔盐湖夏季卤水组成,在实验室进行了卤水冷冻、分阶段连续变温蒸发实验,揭示了卤水冷冻、多温蒸发结晶路线和析盐规律。实验结果表明:夏季盐湖卤水蒸发析盐过程依次为芒硝、水石盐、氯化钠、氯化钾、七水硫酸镁、六水硫酸镁、光卤石、水氯镁石和锂盐(硼酸盐随卤水蒸发不以固体形式析出,富存于老卤中),并将分阶段析盐序列绘制在相应的介稳相图上,实验结果与介稳相图基本吻合。     

Encapsulation of lipid by alginate beads reduces bio-accessibility: An in vivoC breath test and MRI study

This paper describes an in vivo study of the use of encapsulation to alter lipid bio-accessibility in the gastro-intestinal (GI) tract. The hypothesis that encapsulation would delay the accessibility of lipid in the GI tract was tested using subjects (N = 11) who consumed either 30 g of ¹³C-labelled sunflower oil encapsulated within 70 g alginate gel particles, or unencapsulated ‘free’ sunflower oil and alginate-only particles (control). Lipid accessibility was determined by the appearance of the ¹³C label in breath carbon-dioxide (CO₂), and the particles behaviour in the GI tract was investigated using non-invasive magnetic resonance imaging (MRI).
