I. Bilberry Powder
Definition and Source
Bilberry powder is a powdered product extracted and processed from the fruits of bilberry (Vaccinium vitis - idaea L.). Bilberry belongs to the genus Vaccinium in the Ericaceae family and is mainly distributed in the cold - temperate regions of the Northern Hemisphere. The fruits are rich in various nutrients. Through scientific processing techniques, the fruits are transformed into a powder form that is convenient for storage, transportation, and use.
Main Components
- Anthocyanins: The most representative components in bilberries, anthocyanins are a class of powerful antioxidants. There is a wide variety of anthocyanins, including delphinidin and cyanidin. These anthocyanins can effectively scavenge free radicals in the body, reduce oxidative stress - induced damage to cells, and play an important protective role in aspects such as eye health and cardiovascular health. For example, in terms of eye health, anthocyanins can promote the regeneration of rhodopsin in retinal cells, helping to prevent night blindness and improve eyesight.
- Vitamins: Bilberries are rich in vitamins such as vitamin C and vitamin E. Vitamin C has functions such as antioxidant and immune - enhancing effects. It can promote the synthesis of collagen and maintain the health of the skin and tissues. Vitamin E is also a potent antioxidant that can protect cells from damage by free radicals. It works synergistically with anthocyanins to enhance the antioxidant effect.
- Dietary Fiber: The dietary fiber in bilberry fruits is retained after being processed into powder. Dietary fiber helps promote intestinal peristalsis, increase fecal volume, prevent constipation, and at the same time regulate the balance of the intestinal flora and maintain intestinal health.
II. Spray - drying
Spray - drying Principle
Spray - drying is an efficient technology for converting liquid materials into dry powder. In the production process of bilberry powder, the pre - treated bilberry fruits are first made into concentrated fruit juice or pulp. Then, the concentrated liquid is pumped to the spray head through a high - pressure pump. The spray head atomizes it into tiny droplets, usually with a diameter ranging from several tens to several hundreds of microns. These tiny droplets rapidly evaporate water in a hot air stream. The temperature of the hot air is generally controlled at around 150 - 200°C. In a very short time, the water in the droplets is completely evaporated, and the solid components form dry powder particles, which are finally collected from the bottom of the drying tower to obtain bilberry powder.
Advantages of Spray - drying
- Maintaining Nutrient Activity: Since the material is exposed to heat for an extremely short time during the spray - drying process, usually only a few seconds to tens of seconds, and the drying temperature is relatively low, it can maximize the retention of heat - sensitive components in bilberries, such as various vitamins and anthocyanins. Compared with traditional drying methods, the loss of nutrients is greatly reduced, ensuring the high quality and efficacy of the product.
- Good Product Morphology: The bilberry powder obtained by spray - drying has a uniform particle size and good fluidity and dispersibility. This makes it more convenient for bilberry powder to be evenly mixed with other raw materials when used as a dietary supplement and flavoring agent. Whether in the production process or when used by consumers, it can quickly dissolve or disperse in liquids or other food matrices without caking, improving the convenience of product use.
III. Instant - solubility Characteristics
Instant - solubility Principle
The spray - drying process endows bilberry powder with instant - solubility characteristics. By precisely controlling the parameters of spray - drying, such as atomization pressure, hot air flow rate, and temperature, the particles of bilberry powder formed have a large specific surface area and high surface energy. When in contact with water or other solvents, the solvent molecules can quickly penetrate into the powder particles, and at the same time, the powder particles can quickly disperse, thus achieving rapid dissolution. Generally, it can completely dissolve in water within a few seconds to a few minutes to form a uniform solution.
Advantages of Instant - solubility
- Convenient to Use: For consumers, the use of instant - soluble bilberry powder is extremely convenient. Whether it is added to milk or yogurt at breakfast, or added to water to replenish water after exercise, it can dissolve quickly without the need for long - term stirring or waiting. This characteristic meets the needs of people in modern fast - paced life for convenient foods, enabling bilberry powder to be more widely applied in daily diets.
- Expanding Application Scope: In the food industry, the instant - solubility characteristic makes it more convenient to add bilberry powder to various liquid foods, such as beverages and soups, providing more possibilities for product innovation. At the same time, it is also easy to make it into instant tablets, capsules, and other dosage forms as dietary supplements, which are convenient for consumers to carry and take.
IV. Dietary Supplements
Nutritional Supplementation Function
As a dietary supplement, bilberry powder can provide the human body with a rich variety of nutrients. The vitamins, minerals, and dietary fiber it contains help maintain the normal physiological functions of the human body. For example, antioxidant vitamins such as vitamin C and vitamin E can enhance immunity and prevent colds and other diseases. Dietary fiber is beneficial to intestinal health and promotes digestion and absorption.
Health Benefits
- Eye - protecting Efficacy: The anthocyanins in bilberry powder are particularly beneficial to eye health. It can improve blood circulation in the eyes, enhance the antioxidant capacity of eye tissues, and prevent eye diseases such as retinopathy and macular degeneration. For people who use electronic devices for a long time and are prone to eye fatigue, as well as middle - aged and elderly people to prevent eye aging, bilberry powder is an ideal choice for dietary supplementation.
- Cardiovascular Protection: Anthocyanins and other antioxidant components can reduce the levels of cholesterol and triglycerides in the blood, inhibit platelet aggregation, and reduce the risk of atherosclerosis, thus playing a protective role in cardiovascular health. Long - term consumption of bilberry powder helps maintain the normal function of the cardiovascular system and reduces the incidence of cardiovascular diseases.
V. Flavoring Agent
Flavor Characteristics
Bilberry powder has the unique sweet - and - sour flavor of bilberry fruits. This flavor has a fresh fruit - like sourness and a moderate sweetness, with a rich and unique taste. Its sourness is not sharp and pungent, but soft and layered, and the sweetness is relatively light, which can add a natural and fresh fruit flavor to food.
