Ice cream defects arise due to issues in the selection of ingredients or improper processing methods. A bitter taste can result from excessive or low-quality flavoring agents. High flavors stem from poor-quality ingredients such as substandard dairy or flavoring products. An acidic defect is typically caused by sour dairy products, indicating spoilage. Unnatural flavors are linked to the use of synthetic or imitation flavoring substances. Identifying these causes helps in maintaining product quality and consumer satisfaction.
