Flashcards
What does acid value measure?
What does acid value measure?
It measures the concentration of free fatty acids in a substance.
Acid value vs. quality
Acid value vs. quality
A higher acid value suggests lower quality due to increased free fatty acids from hydrolysis or oxidation.
Significance of monitoring acid value
Significance of monitoring acid value
Monitoring acid value helps determine the freshness and quality of fats and oils used in food production.
Study Notes
Acid Value Measurement
- Measures the amount of free fatty acids present in a substance, such as fats and oils
- Expressed as the number of milligrams of potassium hydroxide (KOH) required to neutralize the free fatty acids in one gram of fat or oil
Relation to Fat and Oil Quality
- High acid value indicates the presence of a high level of free fatty acids, which can affect the quality and stability of fats and oils
- Fats and oils with high acid values are more prone to spoilage, oxidation, and off-flavors
- Low acid value indicates a higher quality fat or oil with fewer free fatty acids
Importance in the Food Industry
- Monitoring acid value helps to ensure the quality and freshness of fats and oils used in food production
- Regular acid value testing helps to detect spoilage or contamination, preventing the use of low-quality ingredients in food products
- Maintaining a low acid value is crucial in the production of high-quality food products with a longer shelf life
