observe the machinery and ingredients they were using for the manufacturing of ice cream
Answers
Answer:
Explanation:
Modern ice cream is produced from following raw materials:
Dairy products (milk, cream, butterfat)
Sugar
Flavorings
Approved additives that prevent creation of ice crystals during production process
Eggs
Air, which improves ace creams ability to absorb flavoring and removes the feeling of overy soggy and heavy material.
Production steps:
1. Initial mixing of materials, pasteurizing (heating at high temperature to kill of any harmful bacteria) and homogenizing (thorough mixing of the cream in attempt to break down any fat globules until the mixture is perfectly smooth and uniform).
2. After the addition of flavors, colors and fruit purees, mix is left to stand for around four hours to cool down.
3. Special barrel freezer machine then takes the mix and gradually freezes only one part of the water crystals making the mix harder. During the same time, machine also pumps clean air into the ice cream, which by the end will hold over 50% of the ice cream volume. Without that air in its structure, ice cream would be hard as an ice cube.
4. Semi frozen mixture is then introduced with the final mix of toppings, such as fruits, nuts, sweets or biscuit mix.
5. At the end, ice cream is packaged and blast-frozen to the temperature between -30 and -40 degrees Celsius.
