Product Introduction

Beta‑carotene is a lipophilic tetraterpenoid and provitamin A carotenoid. Its polyene conjugated double‑bond system enables two core physiological functions:

Provitamin A activit

In the intestinal mucosa and liver, beta‑carotene is oxidatively cleaved by β,β‑carotene 15,15′‑dioxygenase (BCMO1) to yield retinal, which is further reduced to retinol (vitamin A) or oxidized to retinoic acid. Conversion is downregulated by feedback inhibition when tissue vitamin A levels reach homeostasis, preventing hypervitaminosis A.

2.Antioxidant mechanism

Beta‑carotene acts as a physical quencher of singlet oxygen (¹O₂) with a rate constant of ~1×10⁹ M⁻¹s⁻¹ and scavenges lipid peroxyl radicals. It terminates chain reactions in lipid bilayers and low‑density lipoproteins, protecting membrane lipids, proteins, and DNA from oxidative damage.

3.Stability mechanism

Microencapsulation forms a protective matrix barrier, reducing photodegradation and thermal oxidation. At 85°C for 30 min, color difference ΔE ≤1.2, supporting use in thermal processing.

Safety Profile

Non‑toxic in normal dietary use: No acute or subchronic toxicity reported at recommended use levels.
No hypervitaminosis A: Conversion to vitamin A is self‑regulating; overload does not cause acute vitamin A toxicity.
Skin & eye compatibility: Non‑irritating, non‑sensitizing in topical formulations.
Labeled caution for supplements: Smokers and individuals with asbestos exposure should avoid high‑dose supplementation (≥20 mg/day) due to epidemiological signals linked to lung cancer risk.
Regulatory status:

FDA: Permanently listed color additive, exempt from certification (21 CFR 73.95, 73.1095, 73.2095).

EU: Authorizedfood color E160a; permitted in cosmetics (CosIng ref. 32173).

EFSA: Safe for use in animal feed for all species (3a160(a)).
