PulpJuica®Strawberry powder Applications:

■ Source

PulpJuica®Strawberry powder is made from fresh strawberry fruit, which must meet three core requirements: variety suitability, suitable origin, and acceptable maturity. Richtek prioritizes varieties with plump flesh, vibrant color (deep or bright red), rich flavor (balanced sweet and sour), and a high solids content (≥8%-10%). These varieties offer a high powder yield and produce powder with superior color and flavor. High-quality strawberries typically come from regions with suitable climates (temperate to subtropical, with large diurnal temperature swings), fertile soil (loose, breathable, and rich in organic matter), and clean water sources, such as Shandong, Liaoning, and Yunnan in China, as well as temperate regions in Europe and the United States. Richtek prioritizes certified ecological farming cooperatives (such as certified green or organic) to ensure clear and controllable source control.

In the food processing industry, PulpJuica®Strawberry powder can be used in baked goods. It can be mixed directly into flour or added to buttercream or frosting to impart the natural strawberry color (pink to red) and aroma, enhancing the sweet and sour taste. Adding strawberry powder to tart crusts and pie fillings can replace some artificial flavors for a more natural flavor. Strawberry powder can be added directly to desserts for flavoring and coloring, avoiding the problem of excess moisture associated with fresh strawberries while streamlining the production process (no fresh fruit processing is required). For strawberry-flavored popsicles and milkshakes, strawberry powder can be mixed with milk, light cream, and other ingredients to quickly impart a rich flavor. Strawberry powder can be used as a seasoning for potato chips, nuts, and puffed foods, creating strawberry-flavored snacks by spraying or mixing. In the production of strawberry-flavored protein powders and meal replacement bars, it enhances both nutrition and palatability.

In the beverage industry, strawberry powder is used as the core ingredient in strawberry-flavored instant drinks, which can be enjoyed directly with warm or cold water, offering a convenient and quick experience. Strawberry powder can also be combined with other fruit and vegetable powders (such as banana powder and mango powder) to create mixed fruit and vegetable juice powders, offering a more nutritionally balanced blend. In milk tea shops and coffee shops, strawberry powder is used in beverages like strawberry lattes, strawberry milk tea, and strawberry sparkling water. Compared to fresh strawberry jam, strawberry powder is easier to store and use in larger quantities. Adding strawberry powder to sports drinks or functional beverages improves the taste while also providing a boost of vitamins and dietary fiber.

In the health supplement and functional food sector, strawberry powder, rich in vitamin C, anthocyanins, and dietary fiber, can be used as a raw material in tablets, capsules, or granules for immune-boosting, antioxidant, and intestinal health benefits. Adding strawberry powder to nutritional foods for children and the elderly enhances flavor and alleviates the difficulty of taking medication. In meal replacement foods (such as shakes and porridge), strawberry powder is used to flavor and add natural nutrients, meeting low-calorie, high-fiber needs. In infant and toddler foods (such as rice cereal and fruit puree powder), it serves as a safe, additive-free natural flavoring ingredient, perfect for babies.

Strawberry powder (containing antioxidants like vitamin C and anthocyanins) is often added to natural skincare products, such as face masks and lotions, claiming to moisturize and brighten the skin. As a natural flavoring, strawberry powder is also added to pet treats and staple foods to boost appetite and provide a small nutritional boost.

■ Active ingredients

PulpJuica®Strawberry powder retains most of the nutrients naturally found in strawberries. Its main nutrients include vitamins, minerals, dietary fiber, plant compounds, carbohydrates, and natural sugars. Strawberry powder is rich in vitamin C, at levels significantly higher than those found in other fruits. This antioxidant, immune-boosting, and collagen-boosting properties are also present. Strawberry powder also contains a certain amount of vitamin A (or its precursor, beta-carotene), which helps protect vision and maintain skin health. Additionally, strawberry powder contains B vitamins (such as vitamins B1, B2, and niacin), which participate in human metabolism and maintain normal nervous system function. Strawberry powder also contains potassium, which helps regulate electrolyte balance and maintain normal heart function. Strawberry powder also contains minerals such as calcium, magnesium, and iron. Calcium and magnesium contribute to bone health, while iron is involved in hemoglobin synthesis, helping to prevent iron-deficiency anemia.

PulpJuica®Strawberry powder retains the dietary fiber (both soluble and insoluble) found in strawberries, which promotes intestinal motility, aids digestion, and increases satiety, benefiting intestinal health. Strawberry powder is rich in anthocyanins (powerful antioxidants) with anti-inflammatory and antioxidant properties, which may help protect cardiovascular health. Strawberry powder also contains polyphenols, such as flavonoids, which also possess antioxidant activity and can reduce free radical damage to cells. Strawberry powder also contains a certain amount of natural sugars (such as glucose and fructose) that provide energy, while also having a moderate carbohydrate content, making it a natural energy source.

■ Production technology characteristics

The production process of PulpJuica®Strawberry powder usually revolves around the three core links of "raw material pretreatment-dehydration and drying-crushing processing". Common processes include spray drying and freeze drying, and some are also combined with auxiliary steps such as concentration.

During the raw material pretreatment stage, fresh strawberries are selected that are highly mature, brightly colored, and free of pests and diseases. After removing the stems and impurities, they are washed with running water or ozone water to eliminate residual pesticides and contaminants. The washed strawberries are crushed and pulped using a pulping machine (if seeds need to be removed, they can be filtered through a screen). This ensures a uniform texture and facilitates subsequent processing. Some processes also include low-temperature pasteurization of the strawberry pulp to kill microorganisms, prolong the raw material's stability, and minimize nutrient loss.

The drying and dehydration stage is crucial for fruit powder quality, and the two mainstream technologies differ significantly. The spray drying method first concentrates strawberry pulp through a vacuum process (evaporating some of the water under low-temperature, reduced-pressure conditions, concentrating it to a solids content of approximately 15-30%). The concentrated pulp is then pumped into a spray drying tower, where a high-pressure nozzle atomizes the liquid into tiny droplets. This droplet, exposed to the hot air within the tower, is instantly dehydrated and dried into a powder. The finished product is then separated and collected. This method is highly efficient, suitable for large-scale production, and relatively low in cost. However, the high temperatures may cause the loss of some heat-sensitive nutrients (such as vitamin C).

Freeze drying (lyophilization) involves rapidly freezing slices or pureed strawberries at temperatures below -40°C, converting the water into solid ice.

Sublimation then converts the ice directly into water vapor (without passing through the liquid phase) under a vacuum. Finally, the dried strawberry pieces are pulverized into a powder. This method uses low temperature (below 0℃) throughout the process, which can maximize the retention of nutrients (especially heat-sensitive substances such as vitamins and anthocyanins) and natural color and flavor, but it has a long production cycle, high energy consumption, and relatively high costs.

The dried material is pulverized in a grinder and screened through a sieve (usually 80-120 mesh) to obtain a fine, uniform powder, ensuring solubility and excellent taste. The finished product is then sterilized with ultraviolet light or microwaves before being vacuum-packed or sealed with nitrogen to prevent moisture absorption and oxidation, extending its shelf life.
