Blueberry extract stands out as a top choice for improving precision in food processes.

The popularity of blueberry extract continues to increase as the health market continues to expand. The functional ingredients of blueberry extract have led to high demand in the food, beverage, and cosmetic industries. The extract has wide market value because it can be used in different industries. The popularity of blueberry extract continues to increase every time consumers come across its health benefits. The framework of this article is based on four questions that explain the value of the blueberry extract industry and the process of its technological development.

Anthocyanins are the key constituents of blueberry extract. Blueberries contain two primary anthocyanins, namely delphinidin and cyanidin. Polyphenolic compounds and proanthocyanidins are other polyphenols found in the extract. Research shows that the effectiveness of a standardized extract with between 25% and 50% total anthocyanins is the same. To enhance several health indicators, these extracts can be applied.

Antioxidant system support. The product eliminates free radicals. It also stimulates the antioxidant systems of the cells (e.g., Nrf2). This maintains the good state of the cells.

The experiments on volunteers indicated that the product reinstates rhodopsin in the retina and constricts or widens the blood vessels of the eyes, therefore reducing the sense of tiredness in the eyes.

Blueberries visual_assist advantage: A study in 2023 in the European Journal of Nutrition discovered that blueberry extract enhances the glucose and fat metabolism of the body.

On animal studies, blueberry extract was found to penetrate the blood-brain barrier and defend the brain cells in the hippocampus against the damage of oxidative stress.

How should various types of standardized extracts be used in various situations? Presently, the mainstream applications are tiered.

The extracts that are used in dietary supplements, functional beverages, and dairy products contain 10-25% anthocyanin. These extracts satisfy the normal antioxidant requirements of the body.

High-concentration extracts (25%-40% anthocyanin) are employed in special health foods. These are extracts with tested health benefits in sports nutrition and metabolic health products.

These are full-spectrum extracts. These extracts still retain the polysaccharides and complexes of polyphenols. The extracts are extensively used in the cosmetics industry especially in the high-end skin care products due to their anti-glycation and anti photo-aging benefits.

Instability of Anthocyanins. They are unstable due to reaction with pH, light and metal ions. Microcapsules and liposomes help keep them stable.

• Bioavailability Enhancement: Nanoemulsions and phospholipid-based formulas make them 3-5 times more available to the body.

Flavor Synergy: Strong extracts have an unpleasant taste, thus flavors and other ingredients should be combined, especially in drinks.

Pesticide Residue and Heavy Metal Control: The maximum limits for cypermethrin and other pesticide residues have been increased by the new EU regulation (EU) 2021/1317.

Microbiological Risk Management: Cold-processed products (e.g., supercritical fluid extraction) have superior microbiological indicators.

Authenticity Verification: To verify fraud with cheap berry types (including blueberry and blackcurrant), DNA barcodes must be examined.

U.S. Market: Product design can use health claims approved by the U.S. Food and Drug Administration (FDA), such as antioxidant content, heart health and structural function claims.

EU Market: The European Food Safety Authority (EFSA) requires comprehensive evaluation. Currently, health claims approved under Article 13.5 (such as maintaining normal vision) are in use.

Asia Pacific Market: The National Health Commission of China has approved blueberry extract and Japan has developed relevant methods through its functional food labeling system.

Technology facilities production value chain. Three areas must be improved by big producers. The use of sonic extraction and membrane technology allows reduction of solvent residue and higher retention of active ingredients. Internationally certified materials like USDA Organic and EU ECOCERT have a higher market value. The entire production process of the product is facilitated by blockchain technology human-animal exchanges.
