γ -nonolactone (CAS 104-61-0) has become a core raw material for food and daily chemical flavorings due to its outstanding coconut-cream aroma and stable chemical properties. Its application requires attention to:
Concentration control: Food additives should comply with national standard limits. For cosmetics, it is recommended to be ≤5% to avoid oily odors.
Storage requirements: Keep sealed, away from light, and store at room temperature in a dry place (shelf life: 1 year).
Substitution trend: Biological synthesis processes (such as microbial fermentation) are gradually replacing traditional chemical methods to reduce costs and environmental burdens.
1. Flavor blending:
Coconut essence: Main component, accounting for up to 30%;
Complex fruit aroma: Used in peach, apricot, almond, tropical fruit and cream essence.
2. Cosmetics and daily chemicals
Fragrance application:
Milk-scented perfumes, children's products (toys, skin care products), white flower-scented perfumes (gardenia, jasmine);
Recommended addition amount: 0.1% - 5%. Excessive addition may cause an oily odor.
3. Pharmacological research
Experiments have shown that it can antagonize the neurobehavioral abnormalities induced by cocaine, which may be related to the structure of the γ -lactone ring, but it has not been applied in clinical practice.
Acute toxicity: Oral LD₅₀ in rats: 6600 mg/kg (low toxicity); Rabbit skin LD₅₀ >5 g/kg
Irritation: Contact with rabbit skin at 500 mg/24 hours: Mild reaction; 100 mg/24h: Strong reaction
Mutagenicity: Bacillus subtilis DNA repair test: Negative (20 mg/disc)
Regulatory compliance: Complies with the "Standard for the Use of Food Additives" (GB 29954-2013) of China and FEMA 2781 certification
Safe operation: Avoid skin and eye contact. Protective equipment must be worn during operation. Store in a well-ventilated environment
