Yeast breads containing oils varied in fatty acid composition: effects on sensory panel acceptability

Area of Science:

• Food Science
• Sensory Evaluation
• Nutritional Science

Background:

• Shortening ingredients in bread significantly impact product functionality and health.
• Limited data exists on how various shortenings influence bread palatability and consumer acceptance.
• Understanding these effects is crucial for developing healthier and more appealing bread products.

Purpose of the Study:

• To compare the sensory acceptability of yeast-leavened wheat breads formulated with different primary fatty acid types of shortenings.
• To evaluate the impact of saturated (coconut oil), monounsaturated (canola oil), and unsaturated (soybean oil) fatty acids on bread characteristics.

Main Methods:

• Standardized bread formulations and preparation methods were employed.
• A 16-member semi-trained sensory panel evaluated breads.
• Sensory attributes assessed included color, flavor, texture, tenderness, and overall acceptability on a seven-point hedonic scale.

Main Results:

• No significant differences were observed in bread color or texture across shortening types.
• Canola oil bread demonstrated significantly superior flavor compared to soybean oil bread.
• Both canola and soybean oil breads were significantly preferred over coconut oil bread for flavor, tenderness, and overall acceptability.

Conclusions:

• The type of fat used as a shortening agent significantly influences the flavor, tenderness, and overall acceptability of wheat bread.
• Shortenings rich in monounsaturated and unsaturated fatty acids (canola and soybean oils) result in more palatable bread than those rich in saturated fatty acids (coconut oil).
• These findings provide valuable insights for optimizing bread formulations to enhance consumer preference and potentially health benefits.
