WHOLE GRAIN WHITE VANILLA CUPCAKES Kenia Delgado, Enrique Flores,Ha Nguyen, Ratna Wirantana, Stephanie Wong
Introduction Advocating for whole grains In the marketplace, consumers have a wide variety of grain-based options. Consumers choose refined grains over whole grains. Refined grains are also high in solid fats and added sugars
Advocating for whole grains Whole grains contain some of the following nutrients: Iron Magnesium Selenium B-vitamins Dietary fiber (varies with whole grain) According to the USDA Dietary Guidelines for Americans: -Recommended grain intake is 6 oz and 3oz should come from whole grains. -about 3-5 servings per day of whole grain for anyone age 9 and up
Advocating for whole grains Some of the health benefits of consuming whole grains according to research: Reduce the risk of cardiovascular disease Lower body weight Reduced incidence of type 2 diabetes Reduce the risk of some type of cancers
Purpose/Objectives To assess the color and sensory characteristics of whole-grain enriched white cupcakes. And consumer acceptability. Variables: Independent variables control: white (all purpose flour) cupcakes variant 1: 20% brown rice & 80% all purpose flour Variant 2: 100% white whole wheat flour. Dependent Variables Color and consumer acceptance Key words: whole grain, consumer acceptance, sensory evaluation, 9-point hedonic scale, color measurement.
Research using barley and whole wheat Gomez & others (2010) Layer cakes Whole grain flours (wheat, rye, triticale, huss-less barley, and tritordeum) v. white flour of the same grains Wheat flour received highest score in 9 scale hedonic test Sharma & Gujral (2013) Cookies wheat-barley flour blends (100% wheat flour, 25 parts flour 75 parts wheat flour, 50 parts barley flour 50 parts wheat flour, 75 parts barley flour 25 parts wheat flour and 100% barley flour) 9-point hedonic scale results: panelist preferred cookies made from 100% barley or 100% wheat flour compared to a blend between the two. Sullivan & others (2010) dough and breads produced from milled, peeled and pearled barley in different ratios (30,50, 70, and 100%) to wheat flour. Higher levels of barley significantly increased L* value of bread crust. (lighter crust)
Research Continued Frost & Others (2011) Chocolate chip cookies Percentage ratio substitution of 0,30, 40, 50, 60 and 70% barley flour to all-purpose flour. Color Results: control and 70% barley were similar in lightness values (L*) than the rest. The 30% and 40% barley cookies were darker than the rest. More barley meant lighter in color Wojtoxicz & others (2013) Corn snack product Samples had 10%, 20%, 30%, 40%, and 50% buckwheat flour. Color Results: greater the percentage of buckwheat flour the lesser the brightness (L*) value. The higher percentage of buckwheat added into the corn product produced lower consumer acceptability. Acosta & Others (2011) Muffins Waxy Whole Wheat Flour Color Results: As the percentage waxy whole-wheat flour went up, the darker the color. The higher the percentage of waxy whole wheat flour, the lower the score on the 9-point hedonic scale.
Research Continued Prasopunwattana & Others (2008) wheat tortillas enriched with whole barley flour Lower (L*) which means darker color for all wheat flour barley compared with bread flour (control) Participants rated Control tortillas higher than barley tortillas for overall acceptability and color. Commercial product was also rated higher than whole barley flour tortillas. Toma & others (2009) Cookies and burritos whole grain v. refined flour Color Measurements: whole grain burritos were darker than the refined flour burritos and control cookies were also lighter than whole grain cookies Sensory analysis showed similar consumption between whole grain products and refined flour products.
Research Continued Bassinello & others (2011) Cookies rice and black bean flours v. all-purpose flour cookies made with whole black bean flour had lower acceptance because of appearance. Inglett and others (2015) Sugar cookies wheat flour v. amaranth-whole oat flour (2 variations) v. amaranth-oat bran concentrate. Results for 9-point hedonic scale: no significant difference. Cookies made with amaranth were lighter in color.

Discussion Color Sullivan & others (2010) Barley dough and breads Higher levels of barley significantly increased L* value of bread crust. (lighter crust) Frost & Others (2011) Barley Chocolate chip cookies Control and 70% barley were similar in lightness values (L*) than the rest. The 30% and 40% barley cookies were darker than the rest. More barley meant lighter in color Wojtoxicz & others (2013) Buckwheat corn snack product Color Results: greater the percentage of buckwheat flour, the lesser the lightness (L*) value. Acosta & Others (2011) Waxy Whole Wheat Flour Muffins The higher the percentage waxy whole-wheat flour, the darker the color of the muffins.
Nutrition Facts 80 g RACC / serving (cupcakes) total ingredients is 825 g total flour 237.4 g flour percentage per recipe (237.4 g /825 g) x 100 = 29% flour
Nutrition Facts Control (100% All purpose flour)
Nutrition Facts - Variant 1 (20% brown rice + 80% all purpose flour)
Nutrition Facts - Variant 2 (100% White whole wheat flour)
Differences in Nutrition Facts
Conclusion Customer acceptance/sensory evaluation (hedonic) No significant difference among the products acceptance= brown rice and all-purpose flour blend Color measurements: Significant difference observed in the redness of V2 compared to the others which indicated that white whole wheat may not successfully replace the refined cupcakes in appearances No significant difference observed in the appearance of brown rice and allpurpose flour blend compared to the control which indicated that brown rice with small inclusion in the mixture with refined flour can successfully replace the refined cupcakes in the appearances. Although there was difference in the appearance when substituting whole grain for refined flour, the consumer acceptability were the same which helps increase the consumption to receive potential health benefits.
