为研究微滤处理对Mozzarella干酪的影响,采用液压压榨技术及扫描电镜技术对其4℃,10d成熟期间液相含量及微观结构进行研究.对照组及微滤组Mozzarella干酪的理化成分(除水分、钙、磷外)差异不显著(p>0.05).两组干酪的液相含量/水分含量随着成熟期的延长而减少,液相部分的蛋白质含量微滤组低于对照组,而缓冲能力高于对照组.扫描电镜结果显示,随着成熟期的进行,蛋白质基质吸收游离水分,液相通道变窄.对照组Mozzarella干酪的蛋白质基质更加平滑和均一,通道更加多孔等微观现象反应出微滤浓缩对干酪的影响源于干酪用乳的不同.

Thermodynamics being among the most synthetic theories of physics and the mass-energy relation E = mc2 among the most general equations of science, it is somewhat surprising that this latter is not explicitly present in the laws of thermodynamics. Coupling this observation with the conceptual difficulties often felt in learning thermodynamics leads to the idea that both situations may have the same cause. On the basis of these clues, this paper is intended to provide complementary arguments to a hypothesis already presented. It consists of showing the existence of an imperfect compatibility between the conventional formulations of the first and second laws of thermodynamics and suggesting the need of the mass-energy relation to solving the problem.

It is well known that thermodynamics raises conceptual difficulties. Far to be limited to students having to learn the subject, this impression is sometimes mentioned by specialists themselves who confess not being totally sure of the consistency of the thermodynamic theory, despite the fact that its practical usefulness is indisputable. The present paper deals with this interesting question and leads to the idea that there is an imperfect convergence between the way of using the thermodynamic tool and the way of understanding its significance. Illustrated by a very simple example, the discussion can be followed by every scientist having the fundamental basis in thermodynamics. The suggested hypothesis is that the Einstein mass-energy relation is closely associated to the concept of entropy, opening a link between thermodynamics and relativity.

The invasive multicolored Asian ladybeetle, Harmonia axyridis （Pallas）（Coleoptera： Coceinellidae）, aggregates inside dwellings during winter to avoid cold weather. This adaptive behavior disturbs homeowners, because of the large numbers of individuals that aggregate, which induces allergic reactions. The migratory flight patterns of this species have been well documented, with individuals preferentially moving toward prominent and high color contrast elements. However, the factors involved in the selection of aggregation sites by this species have yet to be elucidated. Here, we evaluated the influ- ence of （i） the density of individuals and （ii） the type of available shelters on decisions by H. axyridis to settle and aggregate under shelters. A dual choice bioassay conducted in the laboratory demonstrated the presence of mutual attraction to conspecifics. We also found that individuals preferentially settled under red covered shelters compared to transparent shelters, and that the type of shelter outweighed the effect of social interactions among conspecifics. Moreover, this experiment was performed under non-wintering conditions, providing the first evidence that aggregative behavior in this species can also occur under those specific conditions.

Understanding metal accumulation at organ level in roots, leaves and seeds in O. glaberrima (OG) is crucial for improving physiological and metabolic aspects in growing Asian and African rice in salted areas. The micro-analytical imaging techniques are required to reveal its accumulation and distribution within plant tissues. PIXE studies have been performed to determine different elements in rice plants. The existing microbeam analytical technique at the iThemba LABS will be applied for the 2D image mapping of fresh rice tissues to perform a concentration of low atomic mass elements (such as Al, Si, P, S, Cl, Ca, Ti, Mn, Fe, Cu, Br, Zn and K) with detection limits of typically 1-10 μg/g. Comparison of the distribution of the elements between leaves, root and seed samples using uptake and distribution of elements in particular environmental conditions with potential amount of salt in water have been performed. We are also expecting to indicate metal exclusion as salt tolerance strategies from leaves, root, and seed compartments using matrix correlation between samples and between elements on rice species.

为解决干酪加工过程中乳清的处理问题,选用0.14μm的陶瓷膜将脱脂乳中的酪蛋白和乳清蛋白分开,将干酪加工过程的乳清这一"副产物"转变成"联产物".确定的分离操作条件为:温度50℃,流速5m/s,跨膜压力为0.5bar.随着浓缩因子的增加,总蛋白、酪蛋白、总固形物、脂肪及钙的质量分数均显著地增加.该过程得到的透过液无菌、无脂,为天然状态的"理想"乳清,为后续高附加值产品的生产提供了便利,具有广阔的市场前景.采用预酸化步骤可以有效地降低截留液中钙的质量分数,从而降低干酪加工过程可能存在的缺陷问题.
