• What are the main attributes and typical forms of protein ingredients used in food technology?

  - Protein ingredients mainly serve as technological functional additives in food production.
  - They are typically powdered substances, commonly obtained through spray drying.
  - Common examples include whey protein isolate, soy protein hydrolysates, egg albumin protein powder, milk powder, and pea protein powder.

• What are the sources of protein ingredients mentioned in the text?

  - Grains like wheat
  - Oilseeds like soybean
  - Legumes such as beans and pulses
  - Meat
  - Milk
  - Eggs
  - Whey proteins
  - Defatted soybean press cake

• What are the steps involved in making a classic meringue dessert and how can foam formation in other culinary contexts be compared to it?

  - Separate egg whites and whisk them until stiff peaks form to create meringue.
  - Cereal crops like wheat are grown in fields; wheat flour is a common meringue ingredient.
  - Beer's foam resembles meringue's airiness, resulting from carbonation.
  - Meringue can be paired with desserts like cakes, adding texture and flavor contrast.

• How can protein isolates and concentrates be used as ingredients in food according to food technologists?

  - Cereal and legume proteins used in processed meat products
  - Milk proteins used in soups and sauces
  - Suitable for meat, fish, and milk substitutes

• What food products are mentioned in Figure 3 as examples of foamed products?

  - Beer
  - Ice cream

• Describe the visual content related to food products provided in the set of materials.

• What is the aim of the chapter on proteins as functional food ingredients?

  - Provide insight into the differences in production methods
  - Explain resulting changes in protein ingredient properties
  - Describe their functionality in the final food product
