Bilberry Anthocyanins

What is Bilberry Anthocyanins?

Bilberry anthocyanins are natural water-soluble flavonoid pigments extracted from the fruit of Vaccinium myrtillus (bilberry). Chemically, bilberry anthocyanins belong to the anthocyanin family, a subclass of polyphenols. In bilberry fruits, they mainly exist as anthocyanin glycosides, including derivatives of five major anthocyanidins

One of the richest natural sources of anthocyanins is bilberry (Vaccinium myrtillus L.). The primary bioactives believed to be responsible for the numerous health benefits of bilberry anthocyanins are the polyphenolic components that give the fruit its blue-black color and high content. Bilberry has been reported to lower blood glucose, have and lipid-lowering effects, promote defense, and lower oxidative stress, despite its most common promotion for improving vision.

Bilberry Anthocyanins Production Process

There are several methods for extracting bilberry anthocyanins. The following is the most commonly used factory production method, which can be divided into five steps: extraction, impurity removal, purification, concentration, and drying. The specific process is as follows:

1. Extraction

Add acidic ethanol (adjust pH to 2.5–3.0 with food-grade citric acid) to the prepared blueberry raw material. Extract three times at a controlled temperature.

2. Solid-Liquid Separation

Use a plate-and-frame filter press or centrifuge to separate the extract from the pomace, obtaining a clarified crude extract.

3. Concentration (First Concentration)

Under certain conditions, the extract is concentrated to approximately 1/4 of its original volume, and the ethanol is recovered.

4. Macroporous Adsorption Resin Purification

• Resin Type: Macroporous adsorption resin.
• Loading: Apply the concentrated solution at a flow rate of 1–2 BV/h. The loading volume is approximately 1–2 BV until the resin reaches adsorption saturation.
• Water Washing: Wash the resin column with 2–3 BV of purified water at a flow rate of 1–2 BV/h to remove water-soluble impurities.
• Elution: Elute with 4–6 BV of 50% ethanol at a flow rate of 1–2 BV/h. Collect the anthocyanin-rich eluate.

5. Concentration (Second Concentration)

Concentrate the eluate again under reduced pressure to recover ethanol, yielding a relatively concentrated anthocyanin aqueous solution.

6. Spray Drying

7. Sieving and Packaging

Pass the dried powder through a 80–100 mesh sieve to ensure uniformity and fineness. Package under nitrogen protection in light-proof, airtight containers.

Bilberry Anthocyanins Benefits

Antioxidant Protection

Bilberry anthocyanins are among the naturally occurring antioxidants. They help neutralize free radicals, reduce oxidative stress, thereby protecting cells from damage and slowing down aging.

Eye Health and Vision

Bilberry may aid in maintaining clear vision, especially in low light conditions. Bilberry extract 25 anthocyanins have long been regarded as beneficial to eye health, with a focus on improving nighttime vision. This probably comes from the well-known tales of Royal Air Force pilots during the Second World War, who were said to have blamed their devastating accuracy on a lot of bilberry jam.

Cardiovascular Health

People who want to keep their heart and blood vessels in good shape also like bilberry extract. It is believed that anthocyanins help to help the covering of our veins, which thusly can assist with lessening circulatory strain, blood vessel firmness and platelet development. Additionally, anthocyanins aid in cholesterol management.
