Chlorogenic Acid Oxidation-Induced Greening Of Sunflower Butter Cookies As A Function Of Different Sweeteners And Storage Conditions, Sihui Liang, Lilian Were Aug 2017

Chlorogenic Acid Oxidation-Induced Greening Of Sunflower Butter Cookies As A Function Of Different Sweeteners And Storage Conditions, Sihui Liang, Lilian Were

Food Science Faculty Articles and Research

Sunflower butter use as an allergen-free alternative to tree and legume nut butter in baking is limited by chlorogenic acid induced greening that occurs at alkaline pH. Limited information is available on controlling this greening in a food matrix. This study examined how different liquid sweeteners and relative humidity influenced greening of sunflower butter cookies. Doughs had similar initial pH (7.52–7.66) which increased to 8.44–9.13 after baking as ranked: xylitol > maple syrup > corn syrup > honey > agave syrup. Cookies made with maple syrup had the highest moisture and greening corresponding with lowest free chlorogenic acid. The % greening followed the same …


Chlorogenic Acid Induced Colored Reactions And Their Effect On Carbonyls, Phenolic Content, And Antioxidant Capacity In Sunflower Butter Cookies, Sihui Liang, Lilian Were Aug 2017

Chlorogenic Acid Induced Colored Reactions And Their Effect On Carbonyls, Phenolic Content, And Antioxidant Capacity In Sunflower Butter Cookies, Sihui Liang, Lilian Were

Food Science Faculty Articles and Research

The high chlorogenic acid (CGA) content of sunflower seeds causes a greening reaction in sunflower butter baked products which can deter application of sunflower butter as an allergen-free alternative to other plant and dairy based butters. This study focused on how greening intensity of sunflower butter cookies made with different sweeteners (maple, agave, corn syrups, honey and xylitol) affected greening, protein oxidation products, Folin and ABTS•+ radical scavenging ability. Cookies made with maple syrup and xylitol had higher pH and resulted in more greening. The dough made with agave syrup had highest total carbonyls caused by its highest reducing …
