Hydrolysis Of Chlorogenic Acid In Sunflower Flour Increases Consumer Acceptability Of Sunflower Flour Cookies By Improving Cookie Color, Christine Lo Verde, Criselda Toto Pacioles, Natalie Paterson, Jamie Chin, Cedric P. Owens, Lilian W. Senger

Food Science Faculty Articles and Research

Sunflower meal, a byproduct of sunflower oil pressing, is not commonly used in alkaline baking applications. This is because chlorogenic acid, the main phenolic antioxidant in sunflower seeds, reacts with protein, giving the baked product a green discoloration. Our group previously demonstrated that a chlorogenic acid esterase from Lactobacillus helveticus hydrolyzes chlorogenic acid in sunflower dough cookie formulations, resulting in cookies that were brown instead of green. This study presents a sensory analysis to determine the acceptability of enzymatically upcycled sunflower meal as an alternative protein source for those allergic to meals from legumes or tree nuts. We hypothesized that …

A Competitive Assessment Of Commercial Elderberry (Sambucus Sp.) Products And The Evaluation Of Copigmentation Within Elderberry Tinctures, Joseph A. Galetti Phd

Electronic Theses and Dissertations

Elderberry (Sambucus sp.) fruit is a healthful food with a variety of reported curative properties and is among the richest sources of anthocyanic pigmentation, which are the primary factors for its commercial use. Although a variety of value-added elderberry products are available to consumers, it is questionable as to which product form contains the highest nutrient levels and color stability characteristics, and represents the best value to consumers. It was the objectives of this research to evaluate a variety of commercial elderberry products, and to develop a value-added elderberry product with enhanced nutrient and color stability.

Effect Of Roasting Conditions On Hardness, Moisture Content And Colour Of Pistachio Kernels, Ahmad Shakerardekani

Ahmad Shakerardekani

Roasting of whole-kernels is an important step in the production of pistachio paste. The effect of

hot air roasting temperatures (90-190°C) and times (5-65 min) on the hardness, moisture content and colour

attributes (‘L’, ‘a’ and ‘b’ values and yellowness index) of both whole-kernel and ground-state were investigated

using response surface methodology (RSM). Increases in roasting temperature and time caused a decrease in all

the responses except for ‘a’ value of ground-state. The interaction and quadratic models sufficiently described

the changes in the hardness and colour values, respectively. The result of RSM analysis showed that hardness

and colour attributes (‘L’ …
