Articles Functional Foods Reduction of oil absorption in deep-fried, battered, and breaded chicken patties using whey protein isolate as a postbreading dip: effect on lipid and moisture content.
Summary
The effectiveness of whey protein isolate (WPI) solution asa postbreading dip to reduce oil absorption in deep-fried, battered, and breaded chicken patties was investigated. Chicken patties were battered, breaded with either crackermeal or Japanese breadcrumbs, and dipped in WPI solutions prepared at 4 different protein concentrations (0%, 2.5%, 5%, and 10%, w/w WPI) that were adjusted to pHs 2, 3, and 8 before being deep fried. Undipped chicken pattiesserved as the control. Overall, the most effective treatment was observed for WPI solutions made at high concentrations (5% and 10% WPI) at low pH levels (pHs 2 and 3). The highest lipid reduction observed for crackermeal patties (CMP) was 31.2% for patties treated with 5% protein solutions at pH 2 while the highest lipid reduction for Japanese breadcrumb patties (JBP) was 37.5% for pattiestreated with 10% protein solutions at pH 2. Oil degradation and batter, breading, and whey pickup did not significantly affect final lipid and moisture content. Moisture content was generally lower in patties treated at low pH levels (pHs 2 and 3). The results indicate that the usage of WPI as a postbreading dip is a promising alternative in reducing fat content in fried foods since it couldsimultaneously fulfill the steady demand for fried foods and contribute to the growing effort of Americans to consume less fat.

Functional Properties of Honey, Propolis, and Royal Jelly
Summary
Honey, propolis, and royal jelly, products originating in the beehive, are attractive ingredients for healthy foods. Honey has been used since ancient times as part of traditional medicine. Several aspects of this use indicate that it also has functions such as antibacterial, antioxidant, antitumor, anti-inflamatory,antibrowning, and antiviral. Propolis is a resinous substance produced by honeybees. This substance has been used in folk medicine since ancient times, due to its many biological properties to possess, such as antitumor, antioxidant, antimicrobial, anti-inflammatory, and immunomodulatory effects, among others. Royal jelly has been demonstrated to possess numerous functional properties such asantibacterial activity, anti-inflammatory activity, vasodilative and hypotensive activities, disinfectant action, antioxidant activity, antihypercholesterolemic activity, and antitumor activity. Biological activities of honey, propolis, and royal jelly are mainly attributed to the phenolic compounds such as flavonoids. Flavonoids have been reported to exhibit a wide range of biological activities,including antibacterial, antiviral, anti-inflammatory, antiallergic, and vasodilatory actions. In addition, flavonoids inhibit lipid peroxidation, platelet aggregation, capillary permeability and fragility, and the activity of enzyme systems including cyclo-oxygenase and lipoxygenase.
