The Effects of Analogous Food Color on Perceived Flavor: A Factorial Investigation

We extend research testing the effects of food color on flavor perception to analogous color. Analogous colors are those found next to each other on the color wheel. Subjects were assigned the task of tasting and evaluating a fruit-flavored beverage. Actual fruit flavor at two levels and beverage color at three levels were manipulated in a full factorial, between-subjects design. Thus each subject tasted and evaluated a single color/flavor combination. Results show that the small differences in food color represented by analogous color are sufficiently distinct and meaningful to consumers to significantly affect their ability to correctly identify the flavor of color-associated foods, as well as to form distinct flavor profiles and particular preferences—much as the grosser distinctions represented by complementary food color have been shown to do previously.

改善方便米粉入味特性的工艺研究

以大米为原料,对波纹米粉的制作工艺进行了研究。结果表明,根据不同米质通过调节挤压参数使粉丝碘呈色度（IOD）控制在1．3～1．6品质最好。米质要求直链淀粉含量在18％～20％最好,不同的米质可以通过品种配比调节或添加玉米淀粉、马铃薯淀粉来达到相应效果。

卷烟香精香料中5种加香物质的气相色谱质谱法检测

文章介绍了用气相色谱-质谱联用技术（GC- MS）测定卷烟香精香料中乙基环戊烯醇酮、烟酮、邻位香兰素、α-大马酮和巨豆三烯酮（A、B、C、D）共5种加香物质的检测方法。该方法在试样中加入以萘为内标的二氯甲烷溶液振荡萃取,无水硫酸钠干燥后取上清液进行GC- MS检测,对巨豆三烯酮A、B、C、D 4种E/Z异构体采用混合标准品峰面积归一化法对各种异构体浓度进行换算,然后用内标法建立标准曲线。实验结果表明,该方法中各物质的线性相关系数R2均在0.997以上,5种加香物质的加标平均回收率范围为88.9%～97.3%,相对标准偏差（RSD）范围为3.19%～7.82%。该方法具有简便、快捷、灵敏度高的优点,适合卷烟香精香料中加香目标物质的检测。     

Bug planet: Frontier myth in Starship Troopers

This paper examines Paul Verhoeven's 1997 film Starship Troopers against Robert A. Heinlein's eponymous 1959 novel, arguing that both productions reinscribe the ideologies of America's mythic frontier history in their fictional futures. The paper shows that despite the conspicuous postmodernisation of narrative in Verhoeven's adaptation, components of the frontier mythology codified in Heinlein's novel— expansionism, Social Darwinism and a violent relationship with the indigenous Other—remain at the film's thematic centre.
