I actually tried "Rocabo Donuts (Maple)" sold by Seijo Ishii. 50% less sugar than regular donuts. The price is 399 yen (excluding tax).
"Low-Carb Donuts" are simple old-fashioned donuts. 50% less sugar than general donuts and 8.4g (0.14oz) of sugar per piece (compared to "Cake Donuts" from the Standard Tables of Food Composition in Japan 2015). The decisive factor for the taste is organic maple syrup. Maple syrup raw material imported directly from Canada by Seijo Ishii is used.
3 pieces in 1 bag (individual packaging). The nutritional components are as follows (per piece).
Calories: 180kcal
Protein: 3.1g (0.04oz)
Lipid: 14g (0.49oz)
Carbohydrate: 14g (0.49oz) (9.8g (0.28oz) of sugar, 4.2g (0.07oz) of dietary fiber)
Salt equivalent: 0.22g (0.78oz)
* 8.4g (0.14oz) of sugar excluding erythritol
The size is a little small. It is slightly soft, and the slight sweetness of maple gradually spreads as you chew. Eat with moist dough ◎. It's perfect as a snack when you're a little hungry. I'm glad that you can enjoy donuts with high sugar content with a sugar mass of 8.4g (0.14oz)!
Three pieces are included in one bag, and each piece costs about 140 yen, which is a little expensive considering the size. The taste and texture are almost the same as ordinary donuts (although the sweetness is modest), so it is also recommended as a sweet to help you when you can't stand sweets.
