Lexan is a registered trademark for SABIC Innovative Plastics’ (formerly General Electric Plastics) brand of a thermoplastic polycarbonate. Lexan is the brand name for polycarbonate sheet and resin in a wide range of grades. Lexan is mainly used in three domains: building (glazing and domes), industry (machine protection and fabricated parts) and communication and signage. Common usages include space and sports helmets, clear high-performance windshields and aircraft canopies, motor vehicle headlight lenses, and bullet-resistant windows. Lexan is also used to produce varying sizes of food storage containers and is highly prized in the industry as a durable and non-flavor transmitting material. It is often clear and very hard. (Business Wire, March 27, 20031) The first controlling image applied to African-American women is that of the mammy— the faithful, obedient domestic servant. Created to justify the economic exploitation of house slaves and sustained to explain Black women’s long-standing restriction to domestic service, the mammy image represents the normative yardstick used to evaluate all Black women’s behavior. By loving, nurturing, and caring for her white children and “family” better than her own, the mammy symbolizes the dominant group’s perception of the ideal Black female relationship to elite whitemale power. Even though shemay be well loved and may wield considerable authority in her white “family,” the mammy still knows her “place” as obedient servant. She has accepted her subordination. ( Collins 72–73) Black women are not absent from the archive of U.S. culinary production, particularly its folktales, ephemera, and material culture. The prominent placement of commercial figures such as the Quaker Oats Company’s Aunt Jemima illustrates that visibility is not the central problem in the excavation of the relationship between Black women and U.S. food histories. Rather the distorted representations of Black women in Lost Cause—inspired cookbooks, live-action cooking demonstrations atWorld’s Fairs, and the advertisements of the post-Reconstruction era have formed forceful and lasting impressions in the thinking that surrounds Black women and food. These portrayals of Black women as naturally and joyfully servile, unfit for freedom, and deeply dependent on whites for their sense of self are embedded in national food culture and still resonate in contemporary popular culture. (Chatelain 32) The Minnie Jackson Character epitomizes the sassy Black cook who shoots off her mouth, wisecracks, has a lot of folk knowledge, is often pleasantly plump, and knows her way around the frying pan. This imagery is carefully crafted, welcomed, and rewarded within a white dominated media, both historically and contemporarily. If as many scholars have argued, these “controlling images” have material consequences in the lives of Black women in general, whatmay be the specific implications for Blackwomenwho cook professionally? In what ways are Black female culinary professionals and culinary personalities operating

lexan 天花板：案例研究

Lexan 是沙伯基础创新塑料（前身为通用电气塑料）热塑性聚碳酸酯品牌的注册商标。Lexan 是各种等级的聚碳酸酯板和树脂的品牌名称。Lexan 主要用于三个领域：建筑（玻璃窗和穹顶）、工业（机器保护和制造零件）以及通信和标牌。常见用途包括太空和运动头盔、透明的高性能挡风玻璃和飞机顶篷、机动车辆前灯透镜和防弹窗。Lexan 还用于生产各种尺寸的食品储存容器，作为一种耐用且无味的材料在行业中备受推崇。它通常很清楚，也很困难。（美国商业资讯，3 月 27 日，20031）适用于非裔美国女性的第一个控制形象是妈咪——忠实、顺从的家庭佣人。为了证明对家奴的经济剥削是合理的，并持续解释黑人妇女长期限制家务服务，妈咪形象代表了用于评估所有黑人妇女行为的规范标准。通过爱、养育和照顾她的白人孩子和“家庭”而不是她自己，这位妈妈象征着占主导地位的群体对理想的黑人女性与精英白人男性权力关系的看法。尽管她可能很受人爱戴，并且可能在她的白人“家庭”中拥有相当大的权威，但这位妈妈仍然知道她作为听话仆人的“位置”。她已经接受了她的从属地位。( 柯林斯 72–73) 美国烹饪生产档案中不乏黑人女性，尤其是它的民间故事、昙花一现和物质文化。贵格会燕麦公司 (Quaker Oats Company) 的杰迈玛姑妈 (Aunt Jemima) 等商业人物的显着位置表明，在挖掘黑人女性与美国食品历史之间的关系时，知名度并不是核心问题。相反，《失落的原因》中黑人女性的扭曲表现——灵感来源的食谱、世博会上的真人烹饪示范以及后重建时代的广告在围绕黑人女性和食物的思想中形成了有力而持久的印象。这些对黑人女性自然而快乐地奴役、不适合自由、自我意识深深依赖于白人的刻画，深深植根于民族饮食文化中，并在当代流行文化中产生共鸣。(Chatelain 32) 米妮·杰克逊这个角色是一个时髦的黑人厨师的缩影，她不屑一顾，说俏皮话，有很多民间知识，通常是令人愉快的丰满，并且知道她在煎锅周围的方式。这种图像在历史和当代的白人主导媒体中都经过精心制作、受到欢迎和奖励。如果正如许多学者所争论的那样，这些“控制性图像”对黑人女性的生活产生了实质性的影响，那么对专业烹饪的黑人女性有何具体影响？黑人女性烹饪专业人士和烹饪名人以什么方式运作 并在历史和当代白人主导的媒体中获得奖励。如果正如许多学者所争论的那样，这些“控制性图像”对黑人女性的生活产生了实质性的影响，那么对专业烹饪的黑人女性有何具体影响？黑人女性烹饪专业人士和烹饪名人以什么方式运作 并在历史和当代白人主导的媒体中获得奖励。如果正如许多学者所争论的那样，这些“控制性图像”对黑人女性的生活产生了实质性的影响，那么对专业烹饪的黑人女性有何具体影响？黑人女性烹饪专业人士和烹饪名人以什么方式运作
