"Basic Nutrients" Organic Compounds PPT Lesson (Research and Practice Understanding Organic Compounds in Food)

"Basic Nutrients" Organic Compounds PPT Lesson (Research and Practice Understanding Organic Compounds in Food)

Part One: [Research Purpose]

1. Preliminarily understand the ingredients of some foods, and understand the close connection between organic chemistry, human health and food production.

2. Understand the important role of chemistry in production and life.

【Research Task】

1. The role of instant noodle ingredients and important organic compounds

(1) Ingredient list of a certain brand of instant noodles

(2) Important ingredients and functions in ingredients

2. Taking the large amount of cream used in pastries as an example, analyze the role of oil and its impact on human health from the perspectives of producers, consumers and nutritionists.

There are two types of cream used in pastries: vegetable cream and animal cream. Because animal cream is expensive and difficult to preserve, most of the cream used on the market is vegetable cream.

3. The relationship between “organic food”, “junk food” and organic compound ingredients

(1)Organic food

①Meaning: Organic food, also called ecological or biological food, is an internationally unified term for pollution-free natural food. Organic food usually comes from the organic agricultural system and is produced and processed in accordance with international organic agricultural production requirements and corresponding standards.

② Features: It comes from an ecologically sound organic agricultural system. During the production and processing process, no synthetic substances such as chemical fertilizers, pesticides, chemical preservatives, or genetic engineering and its products are used. It is a truly safe and environmentally friendly ecological food.

③Relationship with organic compound components: From the perspective of chemical composition, all organic foods are organic compounds. The organic foods here are all agricultural and sideline products that are produced and processed in accordance with international or national organic food requirements and standards, and have passed national organic food certification. and processed products, including grains, edible oils, dairy products, vegetables, etc.

(2) "Junk food"

①Meaning: "Junk food" refers to food that is unhealthy for the human body. It is food that only provides some calories and no other nutrients, or food that provides more than the human body needs and becomes redundant.

②Characteristics: a. Lack of basic nutrients, b. Few basic nutrients and can easily cause obesity, c. Can cause disease or induce disease.

③Relationship with the composition of organic compounds: The sugars and fats rich in "junk food" or the proteins in "junk meat" are all organic compounds. Substances such as trans fatty acids in fried foods and puffed foods are also organic compounds. These Organic compounds can have adverse effects on human health.
