Premium Red Koji Rice Extract: Natural Colorant & Health Ingredient

Product Overview

CNCSBIO's Red Koji Rice Extract is a high-quality, scientifically-backed ingredient derived from the traditional fermentation of premium rice with Monascus purpureus yeast. This process yields a vibrant, natural reddish-purple pigment and produces a unique profile of bioactive compounds, most notably Monacolin K. As a versatile natural colorant and functional food additive, our extract allows manufacturers to meet the growing consumer demand for clean-label, plant-based products while adding significant value through its documented wellness benefits. Sourced and produced with meticulous care, it represents the perfect synergy of ancient wisdom and modern manufacturing excellence.

Product Features & Advantages

Dual Functionality: Color & Wellness

Unlike synthetic dyes, our extract provides a stable, natural color while simultaneously delivering the well-researched benefits associated with Monacolin K, offering a significant marketing advantage for functional foods and supplements.

Superior Cultivation & Extraction

We use non-GMO indica and japonica rice strains and a proprietary, controlled fermentation process to maximize the yield of desirable compounds while minimizing impurities like citrinin (undetectable in our final product, <0.1 ppm), ensuring a premium, safe product.

Exceptional Stability

The pigment exhibits good stability across a range of pH levels and moderate heat, making it suitable for a wider variety of applications than many other natural colorants.

Synergistic Formulation Potential

Can be effectively combined with other CNCSBIO botanical extracts and food additives, such as Psyllium Husk Powder for digestive health formulas or L-Theanine for stress-supporting supplements, to create comprehensive wellness products.

How to Use Red Koji Rice Extract

Determine Application & Dosage: For coloring: start with 0.1%-0.5% by weight. For functional benefits, dosage depends on the standardized Monacolin K content and target delivery per serving.
Incorporate into Formulation: For dry mixes (powders, capsules, tablet coatings): blend evenly with other dry ingredients. For liquids: pre-disperse in a small amount of water or oil before adding to the main batch to ensure even distribution.
Consider pH and Processing: While stable, avoid prolonged exposure to high heat (>120°C) and extreme pH levels (<3 or >8) to preserve color intensity and compound integrity.
Conduct Stability Testing: Always run shelf-life tests on your final product to ensure color and potency are maintained over time.

Application Scenarios

Nutraceuticals & Dietary Supplements

Primarily used in capsules, tablets, and softgels formulated to support cardiovascular health and maintain healthy cholesterol levels already within the normal range.

Functional Foods & Beverages

Ideal for coloring and fortifying products like health drinks, yogurts, fermented milk, cereal bars, and pastas, turning everyday foods into functional wellness solutions.

Meat Alternatives & Processed Foods

Used as a natural coloring agent to provide an appealing, meat-like red hue in plant-based burgers, sausages, and other meat analogs, as well as in traditional fermented meat and fish products.

Alcoholic Beverages

Historically and currently used in the production of certain rice wines and other alcoholic beverages for both color and character.
