Strawberry Achenes (seeds): Economic Importance, Uses and By-Products

August 25, 2023September 1, 2023 Agric4Profits

Strawberry achenes, often referred to as strawberry seeds, are small, seed-like structures found on the surface of a mature strawberry’s flesh. However, they are not true seeds in the botanical sense. In fact, the strawberry fruit is considered an “aggregate fruit,” meaning it’s formed from multiple smaller individual fruits, each containing a single seed or achene.

Strawberry achenes are tiny, ranging from about 1 to 2 millimeters in size. They have a flattened, somewhat teardrop-shaped appearance. They are typically brown or yellowish in color.

Achenes are distributed across the outer surface of the fleshy part of the strawberry, often referred to as the receptacle. They are embedded within small pits or depressions on the strawberry’s surface. The achenes have a firm texture, similar to that of a seed. They are attached to the receptacle by a small, thin stalk-like structure called a funiculus.

While they might be mistaken for seeds, the achenes serve a different purpose. Each achene is actually a small fruit on its own, containing a single seed. In the wild, these achenes are designed to be dispersed by animals that eat the strawberries. The achenes pass through the animal’s digestive system and are then excreted, potentially leading to the establishment of new strawberry plants in different locations.

The achenes are safe to eat and are commonly consumed along with the fleshy part of the strawberry. They are quite small and typically not a noticeable component when eating the fruit. While they may be commonly referred to as “seeds,” strawberry achenes are distinct structures that play a role in the plant’s reproductive and dispersal strategies, as well as in our culinary experiences with this delicious fruit.

The Economic Importance and Uses of Strawberry Achenes (seeds)

Strawberry achenes, commonly referred to as strawberry seeds, have several economic importance and uses, both in the agricultural and industrial sectors.

Here are some of the key aspects:

1. Propagation: Strawberry achenes are used for propagating strawberry plants. Each achene contains a tiny embryo that can germinate and grow into a new strawberry plant. This is an essential method for strawberry farmers to expand their cultivation and maintain genetic diversity within their crops.

2. Breeding and Research: Strawberry breeders and researchers use achenes to develop new and improved strawberry varieties. They analyze the genetic traits of the seeds to select desirable characteristics such as disease resistance, flavor, size, and yield. This contributes to the continuous improvement of strawberry cultivars.

3. Genetic Diversity: Achenes are a source of genetic diversity within the strawberry species. This diversity is crucial for adapting to changing environmental conditions, pests, and diseases. Breeders can cross different varieties to create plants with desirable traits.

4. Food Industry: Strawberry achenes are used in the production of various food products. They are rich in dietary fiber, which can be extracted and used as a functional ingredient in products like cereals, baked goods, and snacks. The achenes’ small size and texture make them suitable for incorporation into food formulations.

5. Cosmetics and Personal Care Products: Extracts from strawberry achenes are sometimes used in cosmetics and personal care products due to their potential antioxidant and skin-soothing properties. They might be included in creams, lotions, and other skincare formulations.

6. Pharmaceutical Industry: Some studies suggest that strawberry achenes contain compounds with potential health benefits, including anti-inflammatory and antioxidant properties. These compounds might have applications in the pharmaceutical industry for developing natural remedies and supplements.

7. Fragrance and Flavor Industry: Strawberry achenes can be used to extract natural flavors and fragrances. The distinct aroma of strawberries can be captured and incorporated into perfumes, scented candles, and food flavorings.

8. Biodegradable Packaging Materials: The fibrous nature of strawberry achenes can make them a potential candidate for developing biodegradable packaging materials. These materials could help reduce the environmental impact of plastic packaging.

9. Animal Feed: While not a primary use, strawberry achenes can also be fed to certain livestock as part of their diet. However, this use is relatively limited compared to other applications.

The Products and By-products That Can Be Derived From Strawberry Achenes (seeds)

Strawberry achenes, commonly referred to as seeds, are tiny, hard structures found on the outer surface of a strawberry’s flesh. While they might not be the primary focus of consumption, they can still be utilized in various ways to create products and by-products.

Here’s a list of potential products and by-products derived from strawberry achenes:

1. Oil Extraction: Strawberry seed oil can be extracted from the achenes. This oil is rich in essential fatty acids, antioxidants, and vitamins, making it suitable for cosmetic and skincare products. It’s used in moisturizers, serums, and even as a massage oil.

2. Dietary Fiber: The achenes contain dietary fiber that can be used as an ingredient in foods, supplements, or fiber-enriched products. Dietary fiber is essential for digestive health and can help regulate bowel movements.

3. Animal Feed: Strawberry achenes, due to their fiber content, can be included in animal feed formulations. This can be particularly useful in livestock farming for providing dietary fiber to animals.

4. Biodegradable Materials: Compounds from strawberry achenes can be utilized in the production of biodegradable materials, such as bioplastics. These materials are environmentally friendly alternatives to traditional plastics.

5. Seed Meal: After oil extraction, the remaining seed meal can be used as a nutrient-rich ingredient in animal feed. It contains protein, fiber, and other nutrients beneficial for livestock.

6. Natural Fertilizer: The achenes can be composted and used as a natural fertilizer for plants. They provide organic matter to the soil and contribute to its nutrient content.

7. Phytochemical Extraction: Phytochemicals with potential health benefits, such as antioxidants and polyphenols, can be extracted from strawberry achenes. These extracts might find applications in dietary supplements, functional foods, or natural medicine.

8. Flavorings and Extracts: Strawberry achenes can be used to extract natural flavors and extracts for use in the food and beverage industry. These can be employed in a range of products, from confectioneries to beverages.

9. Cosmetic and Skincare Products: Apart from oil extraction, strawberry achenes might be used in cosmetic formulations like exfoliants, scrubs, or masks due to their texture and potential skin benefits.

10. Biofuel Production: Some research suggests that strawberry seeds could be used as a feedstock for biofuel production due to their oil content. However, this application is less common compared to others.

11. Bioremediation: Certain components of strawberry achenes might have applications in bioremediation, helping to clean up soil or water contaminated with pollutants.

It is important to note that the utilization of strawberry achenes for these purposes might require processing, extraction, and refinement to isolate the desired compounds and remove any undesirable components. The commercial viability and feasibility of these applications can vary based on factors like cost, availability, and the specific properties of the achenes.

In conclusion, strawberry achenes play a multifaceted role in various industries, ranging from agriculture to food production, cosmetics, pharmaceuticals, and beyond. Their versatility and potential health benefits make them a valuable resource with economic importance and diverse uses.
