Egg substitutes: use and preference--with and without nutritional information

J Ostrander, C Martinsen, J McCullough

    Journal of the American Dietetic Association
    |March 1, 1977
    PubMed
    Summary

    Consumer perceptions of egg substitutes are complex. Providing nutritional information alone did not significantly alter views, with fresh eggs remaining preferred, highlighting the need for clearer health benefit communication.

    Area of Science:

    • Food Science
    • Consumer Behavior
    • Nutrition

    Background:

    • Egg substitutes are increasingly available, but consumer understanding of their cost, nutritional value, and sensory attributes remains a key area of interest.
    • Consumer perception of food products is influenced by various factors, including cost, nutritional information, and sensory evaluation.
    • Understanding how information affects consumer choices is crucial for food product development and marketing, particularly for alternative protein sources.

    Purpose of the Study:

    • To evaluate consumer perceptions of egg substitutes compared to fresh and dried whole eggs.
    • To assess the impact of providing information on cost, caloric, and cholesterol content on consumer attitudes.
    • To determine how sensory evaluations influence consumer preferences and perceived nutritional value.

    Main Methods:

    • A consumer panel of thirty participants evaluated three egg substitutes alongside fresh and dried whole eggs.
    • Evaluations were conducted before and after participants received information on product cost, calories, and cholesterol.
    • Sensory evaluations were performed to gauge taste and overall preference.

    Main Results:

    • Initially, most consumers believed egg substitutes would be cost-comparable or cheaper than fresh eggs.
    • Providing nutritional and cost information did not significantly alter perceived nutritional value; fresh whole egg remained the preferred product.
    • While sensory evaluation increased perceived nutritional value for all products, preferences decreased for substitutes, indicating information alone was insufficient to change perceptions.

    Conclusions:

    • Information on caloric and cholesterol content of egg substitutes, without context on health benefits, is insufficient to shift consumer perception.
    • Fresh whole eggs were consistently preferred over substitutes, even after nutritional information was provided.
    • Effective communication strategies highlighting the specific health advantages of fat-modified products are necessary to influence consumer choices.
