采写 | 丁欣雨 编辑 | 姜妍 一次罗永浩在西贝莜面村糟糕的用餐体验,让围绕着预制菜的论战在网上持续了数日。顾客在意打着新鲜现炒旗号而贩卖预制菜的营销宣传手段,得知儿 童餐原料西兰花的冷冻保质期竟能达到24个月,让不少人惊觉自己原来早就身处科幻世界。业内人士则辩驳有关"预制菜"的定义,声称维系企业规模的过 程中,食品工业化有其必然性与合理性。 整个餐饮过程都在被资本高度工业化 界面文化:这次事件有个很大的分歧,行业内跟公众对于预制菜的定义是不太一样的。当前食品工业已经发展到了什么程度? 潘隆斐:人类的预制食品很多,比如说我们平时喝的茶叶,但是我们玩这种定义游戏没有太大意义。去年官方曾经对预制菜进行了范围划分,但没有给出 一个明确定义,这样就给预制菜的解释留出很大空间。商家觉得只要不是完全料包的形式走到餐桌上,就不是预制菜。但实际上整个餐饮已经大工业化, 大量东西都是预制的,这个是无可辩驳的。 我们现在把它叫作预制菜也好,或者叫作大工业化的食品也好,在美国历史上曾经也同样造成过比较大的争论。二战的时候需要后勤物资,美国国内开发 出了预制菜大工业,我们熟悉的好多大型食品公司,例如雀巢、M&M豆,当时都是为美军服 ...

Core Viewpoint - China's astronomy is transitioning from "catching up" to "keeping pace" and even "leading" in the field of astronomical observation, as evidenced by the successful operation of major scientific instruments like the FAST and LAMOST telescopes, and participation in international scientific projects like SKA and GOTTA [1] Group 1: Current Developments in Astronomy - The FAST telescope has achieved world-leading status in low-frequency radio astronomy, while space telescopes like Tianwen, Wukong, and Weiyan form a detection matrix in high-energy astrophysics [1] - The upcoming China Space Station Engineering Survey Telescope (CSST) is expected to generate unprecedented amounts of data, discovering thousands of gravitational lens systems crucial for dark matter and dark energy research [2] Group 2: Public Engagement and Education - The CSST's data will serve as a significant scientific resource and a vehicle for public science education, encouraging societal participation in cosmic research and enhancing scientific literacy [2] - The National Astronomical Data Center has established a leading advantage in public astronomy science, utilizing AI models to create intelligent astronomy learning communities that allow public participation in scientific exploration [2] Group 3: Citizen Science Initiatives - The public's involvement in astronomy has accelerated data mining and made scientific exploration a shared endeavor, exemplified by projects like the China-VO supernova search, which has engaged thousands of participants [3] - Experts emphasize the importance of a robust reward mechanism to sustain public contributions to scientific research, advocating for a system that transforms contributions into growth resources [3][4] Group 4: Technological Advancements - The rise of big data, artificial intelligence, and global observation networks is profoundly changing the research methods in astronomy, injecting unprecedented vitality into the field through public science initiatives [4]
