Retort pouches that can be stored at room temperature are available at Yoshinoya's official Yoshinoya mail-order store as "room temperature preservation type gyudon no tsuyu" (beef bowl) ingredients.

Room Temperature Storage Type Gyudon no Togu (Beef Bowl Soup)

It took about five years to develop this retortable gyudon at room temperature in response to many requests from those who do not have freezer space, those outside the cool delivery area, and those in outdoor situations where frozen gyudon ingredients cannot be cooked. Generally, retort processing involves cooking under pressure at high temperatures, which significantly changes the taste, texture, and aroma of the ingredients. However, Yoshinoya has devised a way to keep the taste, texture, and aroma intact by adding special pre-processing before retort processing. By utilizing the knowledge of beef cultivated through its long history and the latest technology, Yoshinoya has created beef bowl ingredients that focus on the texture of the meat. The lineup is as follows

Trial set of "room temperature preserved type gyudon no tsuyu" (two bags of room temperature gyudon no tsuyu): 1,296 yen
