Natural & Synthetic Beta Carotene Powder (1% – 30% CWS / Oil Suspension Grades)
High-Stability Provitamin A & Natural Coloring Agent · Cold-Water Dispersible & High-Density Formulations for Beverages, Supplements & Functional Foods
R&D Insights: Overcoming Oxidation, Color Fading & Dispersion Bottlenecks in Beta Carotene
Technical notes from our carotenoid application & formulation stability lab.
Beta Carotene is a dual-function powerhouse ingredient: it serves as a safe provitamin A source for dietary supplements and acts as a vibrant natural yellow-to-orange coloring agent for beverages and dairy. However, unformulated beta carotene is notoriously hydrophobic, highly sensitive to light, oxygen, and thermal degradation, and prone to rapid ring-fading or precipitation in liquid matrices. Formulators often face major frustrations when raw carotene crystals agglomerate into stubborn orange specks or lose up to 30% potency within weeks of shelf exposure.
Our production facility eliminates these roadblocks through micro-encapsulation beadlet technology and double-shell antioxidant protection (using food-grade tocopherols and ascorbyl palmitate). Whether you need our 10% CWS powder that disperses into crystal-clear orange beverages without ring separation or our oil-suspension grades for softgel filling, we guarantee high light stability, exact HPLC potency recovery, and batch-to-batch color consistency.

Frequently Asked Questions (FAQ)
Q1: What is the main difference between Natural (Blakeslea trispora) and Synthetic Beta Carotene?
A: Natural Beta Carotene is derived via fungal fermentation and contains a favorable blend of stereoisomers (predominantly all-trans and 9-cis), making it highly prized for clean-label supplements. Synthetic Beta Carotene is chemically synthesized to USP standards, offering higher purity assays and greater cost efficiency for large-scale industrial food coloring.
Q2: How does your Cold-Water Dispersible (CWS) grade prevent ring separation in beverages?
A: Our CWS beadlets encapsulate microscopic carotene crystals within a hydrophilic protective colloid matrix. When added to water, the matrix dissolves and releases ultra-fine colloidal particles that remain stably suspended without floating or precipitating.
Q3: How should Beta Carotene Powder be stored to maximize shelf stability?
A: Carotenoids are sensitive to light, oxygen, and heat. Store material in its original nitrogen-flushed packaging in a cool (<20°C), dry warehouse. Promptly reseal inner PE bags after sampling to prevent oxidation.
Q4: What is the recommended dosage for dietary supplements vs. food coloring?
A: For nutritional supplementation, dosages typically range from 2 mg to 15 mg of active beta carotene daily (approx. 6,600 to 50,000 IU). For food coloring and beverage tinting, usage levels generally range from 5 ppm to 50 ppm depending on the desired yellow-orange shade depth.
Q5: How can our formulation team request evaluation samples and HPLC COAs?
