The Expanding Market of Functional Foods

Functional foods, which are designed to provide specific health benefits, are earning increasing popularity due to consumer demand and scientific advancements.

The Health Benefits of Fish Oil

Fish oil is a rich source of omega-3 fatty acids, which reduce the risk of heart disease, arthritis, and asthma, support brain development and function, and play a crucial role in overall wellness. To meet the recommended daily intake, individuals should consume oily fish like salmon or tuna three to four times a week. However, many people fall short of this target.

Addressing the Challenge of Fishy Flavors

While several companies are researching methods to add fish oil to common foods, they've found that even small amounts can affect taste and smell negatively. Would anyone want to eat fish-flavored bread or muffins? The Riddet Institute team has now resolved this issue by microencapsulating the fish oil.

Microencapsulation of Fish Oil

Microencapsulation involves enclosing active ingredients, such as fish oil, in tiny particles. This process helps maintain the stability and bioactivity of the ingredients while minimizing their impact on the taste and smell of the final product.

Advantages of Microencapsulation

1. Prevention of Oxidation: Microencapsulation stops fish oil from oxidizing, which can lead to rancidity and off-flavors. This is achieved by encapsulating the oil in a protective matrix made from natural materials like plant proteins or polysaccharides.
2. Masking Taste and Smell: The encapsulation process successfully conceals the strong marine flavor associated with fish oil, making it suitable for incorporation into various foods.
3. Enhanced Absorption: Microencapsulation also improves the absorption of active ingredients, ensuring that the body can effectively utilize the nutrients present in the fish oil.

Applications of Microencapsulation

• TopGum's Omega-3 Gummies: Companies like TopGum use microencapsulation to incorporate omega-3, derived from fish oil or algae, into gummies. They employ a proprietary TopCap technology that guarantees a high concentration of DHA while retaining a pleasant flavor profile thanks to the addition of essential oils like orange.
• Xampla's Plant Protein Microcapsules: Xampla's technology uses plant proteins to encapsulate oil-based nutrients, demonstrating stability under various conditions, including digestion and pasteurization.

Consumer Testing in Product Development

Consumer testing plays a vital role in the development of microencapsulated products, ensuring that the final products meet consumer preferences and expectations. Ways consumer testing is utilized include:

1. Flavor Profile Optimization: Consumer panels assess the taste and smell of products containing microencapsulated fish oil, providing feedback that helps companies adjust the flavor profiles to ensure consumer satisfaction.
2. Product Stability and Quality: Testing evaluates the stability and bioactivity of the encapsulated ingredients under various storage conditions and over time, guaranteeing the product remains effective and palatable throughout its shelf life.
3. Sensory Evaluation: Sensory testing is conducted to gauge the overall sensory experience of the product, encompassing texture, taste, and smell. This helps fine-tune the product to meet consumer preferences.
4. Consumer Acceptance: Final-stage testing assesses consumer acceptance of the product, taking into account feedback on packaging, labeling, and overall product appeal to ensure the product is ready for the market.

Student Activity: Testing Fish Oil in Ice Cream

As part of a student activity, students add fish oil to ice cream and conduct sensory testing to identify its effects on taste and smell. This activity is an opportunity for students to investigate how and why fish oil is being added to foods and to gain an understanding of the influences and impacts of this technology, as well as the communication and promotion tactics that aid in gaining consumer acceptance of new technologies.
