The Aim / Objective: Using eggplant puree to reduce fats and egg in bakery products to reduce calorie and increase nutritional value of cake (muffins) also, technological and sensory evaluation of muffin produced. Maximizing the use of eggplant from an economic point of view, as it is a cheap and available product in the Egyptian market, maximizing the health benefits of eggplant by producing a product with high nutritional value and low in fat, take advantage of dietary fiber in vegetables, producing a new product with high nutritional and biological value, take advantage of various antioxidants from their natural sources, improving the quality characteristics of products (sensory qualities), especially color and using natural vegetables as fat substitutes in bakery products.
Study Design: Analytical study.
Place and Duration of Study: Department of Bread & Pastries, Food Technology Research Institute, between June 2020 and August 2022. Methodology: We prepared the muffins blend and formulas and did all analysis (chemical – physical – sensory evaluation – texture… for muffins resulted.
Results: Eggplant puree (EP) (25, 50, 75 and 100%) was used to replace fat and egg in the muffins production. Muffins prepared with 25% (EP) had a higher volume than control Muffins. Muffins volume was alikeness between control muffins and the sample used 50% (EP). At 100% replacement level, the muffins volume is minimal. Low-fat and egg muffins with (EP) had higher moisture and minerals also less calories than control. Replacing baking butter by (EP) gave a significant rising in springiness hardness, and chewiness, and a limited result of cohesiveness. But, there were no inequality between control muffins and the acceptance of low (fat and egg) muffins up to 75%. Adding (EP) did not result in undesirable variations in color. Likewise high moisture content in (EP) muffins was acceptable by the panelists. Results clarified that (EP) is an acceptable fat alternative in muffins and efficient in reducing the amount of fat and calories, likewise (EP) could be used as egg replacer in muffins and cakes. Furthermore, during storage moisture loss and increase of muffins hardness was observed in produced muffins. Result showed great acceptance for produced muffins.
Conclusion: This work is an attempt to raise the economic value of eggplant by using it in some bakery products that may not affect its technological properties while reducing the energy percentage and the price of the product. By studying all the technological, sensory and chemical properties, it was found that fat can be replaced by 100% with eggplant puree, and the ability to replace eggs by 25%, as these samples gave a result similar to the control in all the properties of the tests, while the increase in the percentage of replacing eggs with eggplant puree to 50 and 75% led to a decrease In the technological properties, however, it was accepted by a large percentage up to 75 and 85% of the various laboratory tests, and therefore it is acceptable according to the taste of the consumer and from the view point of the producer.
