Beetroot Red E162

Beetroot Red E162 is a controlled natural coloring ingredient that is designated by E-number designation, which is prepared by extracting and concentrating red betalain-based pigments of red betalain to give the E162 its characteristic red to purplish-red color. E162 is available as controlled liquids or powders at specified color value, solubility, with specified specifications limits in order to be able to perform consistently in large-scale production. Its E-number is a regulatory labeling clarity and cross-border trade resource, and hence is a feasible option to manufacturers that have to operate in more than one market and need to have a harmonized ingredient declaration. Formulation-wise, it is hydrophilic and highly compatible with those systems that require a naturally derived red color without the use of synthetic colorants, which upgrades reformulations and portfolio revolutions due to the clean-label and natural sourcing initiatives. Although its color expression is affected by the processing factors of heat, light, oxygen, and pH, these properties are well known on the industrial level, and manufacturers can control the stability via formulation design and control of the process. In general, it is a commercially proven, plant-derived colorant that fits the needs of the modern manufacturing industry in terms of transparency and regulatory familiarity, along with consistent, natural coloration of a broad spectrum of formulated products.

Beetroot Red Colouring possesses a number of distinct physical and chemical properties that can be applied within the formulation and process design of industrial applications. It is a betalain-based water-soluble pigment system that imparts red to purplish-red, and has high color clarity, which enables uniform distribution in aqueous media and does not require emulsification. The pigment demonstrates the best color expression in the near-neutral to slightly acidic environments and predictable sensitivity to heat, light, oxygen, and extreme pH, which allows the formulators to predict the changes in colors and determine the appropriate process parameters. E162 has comparatively good chromaticity in the recommended pH range and does not form any metal complexation to develop color, as compared to many anthocyanin desaturated colors. Its neutral, clean flavor profile is also supported by its molecular structure at normal levels of use, which reduces the interference of sense in finished products. These clear-cut solubility, stability, and interaction characteristics make it an aesthetically transparent choice in colors that provides formulators with a hierarchy of dosage regulation, matrix compatibility, and process optimization during large-scale production.

1. Store in a cool, controlled environment

Store the product in a cool, stable environment that is not subjected to a lot of heat because high temperatures may slowly degrade the pigments.

2. Protect from direct light exposure

Do not expose to bright natural or artificial light, as light can affect color intensity with time, even when in closed packages.

3. Maintain dry conditions

Keep in a dry place, and containers are kept well sealed to avoid moisture permeation, especially in powdered formats.

4. Limit oxygen contact after opening

When containers are opened, immediately reseal them and seal them with little headspace in order to minimize the number of times they come into contact with air.

5. Avoid contact with reactive materials

Store the Beetroot Red product out of power oxidizing agents or other incompatible substances that may affect the stability of the pigment.

6. Follow first-in, first-out (FIFO) practices

Adopt a FIFO system of inventory management so as to have uniform color performance and maximize inventory turnover during production.

As a functional coloring ingredient, Red Beet Extract is normally applied in a manner that manufacturers are conscious of the dosage, dispersion, and sequencing of the various dosage forms. With capsule applications, the pigment is typically pre-combined with excipients or carrier powders in order to obtain even color distribution and avoid speckling, and low-shear mixing is desirable to achieve the same color. When used as a tablet formulation, it may be incorporated either in the dry blending or granulation phase, where regulated particle size and uniform mixing can assist in creating a consistent appearance of the final compression, but not exposing it to too much heat or excessive exposure to the processing. It is usually pre-dissolved in water/or an aqueous phase in liquid systems, followed by final formulation, where even color development becomes possible, and shade intensity can be easily adjusted when up-scaling. In all forms, the formulators normally use such trials to optimize addition levels, test color performance in particular conditions of processing, and guarantee batch-to-batch reproducibility. It is a versatile and technically viable ingredient in multi-dosage production facilities.
