传统煮鸡蛋的方法有两种:在 100 摄氏度的沸水中硬煮,但这会导致蛋黄完全凝固;通过真空低温烹调,在 60 到 70 摄氏度下慢慢炖煮一小时,但这会让蛋白不够熟。科学家现在报告了一种被称为“周期性烹饪”的新方法。它不仅让每一颗煮鸡蛋都能达到完美的均匀熟度,还能提升其营养成分。科学家利用计算流体动力学软件模拟出了这种全新的煮蛋过程:将鸡蛋在 100 摄氏度的沸水和 30 摄氏度的冷水中交替浸泡,每两分钟转移一次,总共持续 32 分钟。在这段时间里,蛋白逐渐变得细腻而富有弹性,蛋黄则保持了奶油般的柔软质感。经过处理后蛋黄中的多酚含量显著增加,这是一种被认为对健康非常有益的微量营养素。 Guardian:Scientists crack what they say is the perfect way to boil an egg 科技日报:如何煮出熟度均匀的鸡蛋?

Start with a fresh view of investing strategy. The combination of risks and fads this quarter looks to be topping. That means the future is ready to move in.Likely, there will not be a wholesale shift. Company actions will aim to benefit from economic growth, inflationary pressures and a return of market-determined interest rates. In turn, all of that should drive the stock market and investment returns higher.
