Flashcards in Butanoic Acid Deck (6)
What is butanoic acid?
- Small simple molecule
- Straight liner chain of 4 carbon atoms
- Rarely occurs in free form in food
- Can be present at trace levels in food
- Significant in food because it can give a rancid odor
- Formation is food reflects catalysed by the hydrolytic enzyme lipase
- Often refferd to as a fatty acid
- Health benefits
Why is butanoic acid significant in food (two reasons)?
- Can give foods a rancid odor
- Can be beneficial for health
How does butanoic acid form in foods?
- Formation due to deteriorative enzymatic reaction catalysed by the hydrolytic enzyme lipase
Solubility properties of butanoic acid?
- Often referred as a fatty acid because it is quite soluble in solvents that are used to dissolve fats during lab analysis in food fats
- It can also dissolve in water systems too
Butanoic acid in fats?
- This acid occurs naturally in some fats in food
- Because it is a fatty acid it can be linked by an ester bond to a glycerol backbone in acyglycerol molecules (glycerides).
- Can be represented at C4:0
- 4 carbon atoms and no double bonds
- Can be found in milk too
Butanoic and fiber?
- Butanoic can act as a fiber
- Evidence that it minimizes the formation of cancers in the lower GI
- Started adding it to foods
