As the world continues to grapple with the challenges of food security and environmental sustainability, the focus on alternative sources of nutrition is growing. One such source that has garnered significant attention is edible insects. A recent study published in the Journal Nutrients has shed light on the acceptance levels of insect-based food products among different age groups in Poland.

The Study

The study focused on assessing the acceptance level of cream-type soups made from tomatoes or white vegetables with the addition of 20% flour from four insect species: mealworm, house cricket, buffalo worm, and grasshopper. The research encompassed 104 subjects, including 55 seniors and 49 young adults. The aim was to understand the attitudes and willingness of consumers to consume insect-based products in their diet.

Findings of the Research

The results suggested that tomato soup and cream of white vegetables with mealworms achieved the highest level of acceptance, while soups with grasshoppers received the lowest ratings. The average score for products with mealworm was 6.63 points on a 10-point scale, while those with grasshopper ranged between 4.23 and 4.38 points. Interestingly, the study found no statistically marked association across age groups, albeit both groups rated all four sensory attributes of the insect-based soups lower compared to the control samples. The control samples, without insect flour, received the highest ratings in both age groups for overall acceptability and individual descriptors.

Importance of Taste and Texture

The study underscored that taste and texture had the strongest influence on the overall acceptance of these dishes. Tomato-based soups had a more pronounced taste and intense color, which helped hide the peculiar taste and appearance of the insect additive. This implies that the base product and the recipe have a significant role in a product containing insects as a hidden ingredient.

Edible Insects: An Eco-friendly Protein-rich Food Source

Insects represent a promising food source due to their high nutritional value, taste, inexpensive and efficient production, and minimal environmental impact. The use of insects as food could potentially help address the global food crisis and contribute to reducing the carbon footprint associated with traditional methods of producing protein-rich food sources.

Future Research Recommendations

Despite the promising results, the research concluded that there is a need for further studies focusing on developing novel, attractive food products that incorporate edible insects. The objective should be to increase the acceptance level of insect-based food products, thus paving the way for a more sustainable and eco-friendly future.
