分蘖洋葱对西式香肠品质及储藏特性的影响

为研究不同添加量分蘖洋葱对西式香肠品质的影响以及储藏期内产品特性的变化,在西式香肠加工中,分别添加10%、20%(以原料肉计)分蘖洋葱汁,同时以未添加分蘖洋葱汁处理为对照,分析产品的色差、质构、挥发性风味成分变化,并通过硫代巴比妥酸值来评价西式香肠在储藏过程中的脂肪氧化程度。结果表明:添加分蘖洋葱汁的西式香肠亮度值增加,红度值有所降低;添加10%分蘖洋葱汁能够显著降低香肠的硬度和咀嚼性,提高香肠的黏着性,同时还可以保持香肠的弹性不变,使香肠具有良好的口感。各类挥发性风味物质的种类产生明显变化,储藏期间脂肪氧化程度随着分蘖洋葱汁添加量的增加而降低。分蘖洋葱汁的添加不仅改善了西式香肠的色泽、口感和风味,同时抑制了西式香肠在储藏期间的脂肪氧化,这为西式香肠的生产及储藏提供了新思路。

以脂肪氧化的标志性产物丙二醛(MDA)为对象,推理脂肪氧化对肉色稳定性影响的关系。结果表明,向肌红蛋白溶液添加MDA,对肌红蛋白的氧化无显著性影响(p>0.05);向牛肉糜中直接添加MDA,不会对线粒体活性、高铁肌红蛋白还原酶活力(MRA)以及牛肉糜红度a*值造成影响。脂肪氧化的产物MDA并不是造成肉色劣变的原因。脂肪氧化的产物促进肉色褐变方面的机理,还有待研究。

A Context Model of Wavelet Coefficients for Image Compression

Through the combination of the idea of the linear prediction used in the GlicBawls coding scheme and the idea of the quantization taken in the CALIC coding scheme to reduce the number of contexts, a new context model of wavelet coefficients for image compression is proposed. Wavelet coefficients are encoded by the arithmetic encoder, with the contexts formed by quantizing linear prediction values. Experimental results show that the model achieves higher lossless compression rate of image than lossless SPIHT and lossless EBCOT used in JPEG2000. In addition, by exploiting the multiresolution property of wavelet, the model can compress the transformed image for progressive resolution and earn higher compression rate for each scale of the image than EBCOT.

转变农民的思想观念：新农村建设成败的关键 ——由建设社会主义新农村引发的思考

当前开展的社会主义新农村建设，不论在理论界还是在实践中都存在着忽视转变农民思想观念的问题。而如果农民的思想观念不能彻底向现代化转变，则所有新农村建设的实施都将成为空谈，甚至会造成像城市现代化过程中出现的思想观念混乱、经济发展偏颇的现代性危机。文章运用历史和逻辑统一的方法，从理论、历史、现状3个层面进行分析，认为虽然经济基础决定上层建筑，但思想观念作为上层建筑对经济的发展也会产生一定的反作用；中国在近代现代化的实现过程中，正是由于在不同的阶段都程度不同地忽视了思想观念的转变，才造成了中国现代化进程中的现代性危机；同时从农民现状来看，思想观念更是滞后于现代化的进程。因此，从伦理的规范、道德的重建、传统的继承等方面转变农民的思想观念就成为新农村建设中不可忽略的重要内容，成为关乎新农村建设成败的关键所在
