Industrial production of kanten (the Japanese name for agar, which translates as “cold weather” or “frozen sky”) began in Japan in the mid-19th century by natural freeze drying, a technique that simultaneously dehydrates and purifies the agar. Seaweed is first washed and boiled to extract the agar, after which the solution is filtered and placed in boxes or trays at room temperature to congeal. The jelly is then cut into slabs called namaten, which can be further processed into noodle-like strips by pushing the slabs through a press. These noodles are finally spread out in layers onto reed mats and exposed to the sun and freezing temperatures for several weeks to yield purified agar. Although this traditional way of producing kanten is disappearing, even today’s industrial-scale manufacturing of agar relies on repeated cycles of boiling, freezing, and thawing.
What are Moon phases?According to NASA, the Moon takes about 29.5 days to orbit the Earth. Over the course of this period, it moves through eight recognisable phases. While the same side of the Moon always faces us, the amount of its surface lit by the Sun changes as it continues along its path. The shifts in sunlight create the different appearances we see from Earth, ranging from a fully illuminated Moon to a thin sliver or near darkness. The eight phases are:。关于这个话题，51吃瓜提供了深入分析
