A goo microorganism is added to the food. It grows rapid becomes the dominant microorganism present in the food and inhibits the growth of bad microorganisms. As grows, it changes proteins or sugars or both in the food and makes it more delicious. Japanese people eat many fermented foods: soy sauce miso, natto, Japanese pickles. Japanese cuisine could not exist. Without these foods Recently, collaborating with a university, a company in Japan developed a special sheet coated with a good microorganism. When you wrap meat or fish in this sheet, the good microorganism protects the food from bad microorganisms. The food naturally begins to ferment without spoiling, and its taste becomes richer and more delicious. The sheet may also solve the food waste problem. Restaurants that use the sheet can keep extra food longer instead of throwing it away. Hints for Understanding 「もし(今) 〜がなければ」 Without ~ 1.8 Without these foods, Japanese cuisine could not exist. ~がなければ Comprehension A Answer true or false. ・できないだろう (could not + 動詞の原形) 仮定法過去 1.

Canned Bread to Feed the rid Have you ever heard of canned bread? This specially pa bread is designed as emergency food. When you open the can tastes as delicious as freshly baked bread. The idea of canned bread originated in the Great Hans Awaji Earthquake of 1995. Immediately after the earthqua a baker named Akimoto Yoshihiko baked 2,000 rolls and s them to the victims. A few days later, he got bad news. Half the rolls went bad before they could be distributed to people need. Therefore, they were thrown away. Akimoto G1 disappointed to hear that. G1 G1 A little while later, one of the earthquake victims said to hi "It was so depressing to have only hard biscuits to eat. I'd like to create bread that keeps for a long time but stays saf G1 Akimoto decided to rise to the challenge. 72 1. What did Mr. Akimoto do immediately after the earthquake? 2. What happened to the rolls that Mr. Akimoto sent? 3. What did Mr. Akimoto decide to create? Opinion 1. Have you ever eaten canned bread? If you have, how did it taste? If you haven't, what do you think it tastes like? go bad ex. The milk will go bad if you don't put it in the fridge. rise to the challenge ex. Our team rose to the challenge and won the tournament.
