THIS FOOD PRESERVATIVES ESL LESSON FOR WHICH ESL LEARNER?
This food preservation lesson is designed for upper intermediate and advanced-level students, particularly those studying food science, health science, nutrition, or ESL learners working in such an industry. The students will learn basic food science concepts, such as enzymes and free radicals, and general nutrition and food safety knowledge.
ESL VIDEO LESSON DESCRIPTION:
This video explains that food can go bad because of microbes (like bacteria and fungi) and oxidation (when molecules change chemically). Through this video lesson, students will learn about various preservatives. Preservatives help prevent these things from happening, making food last longer. Some preservatives, like acids, sugar, and salt, make it harder for microbes to grow. Other preservatives, like antioxidants, stop food from changing colour or flavour. While some preservatives may cause health problems for some people, most are safe and used in small amounts. ESL students will also learn the packaging trick to prevent food from spoiling. Few foods can stay fresh without preservatives, but some packaging tricks can also help that ESL students will learn through this video lesson.
The students will learn new ways to preserve the food, like some consumers and companies are trying to find alternatives, through packaging, like reducing the oxygen around the food, which can help. Still, without some chemical assistance, very few foods can stay shelf stable for a long.
Learning Objectives for ESL learners:
- Understand the concept of food preservation and the different types of preservatives that can be used to prevent food from going bad.
- Learn new vocabulary and keywords through matching and language focus exercises.
- Students will learn about the major factors that cause food to spoil, including microbes and oxidation.
ESL FOOD SCIENCE VOCABULARY
Through this video lesson, students will learn their English language skills, including listening comprehension, vocabulary acquisition, and critical thinking. They may also practice presentation skills through assignments that require them to summarize and analyze the information presented in the lesson.
Furthermore, the ESL students will learn the concept of antimicrobial nitrates, antioxidants and botulism, and many more.
