Influence Of Hesperidin On The Physico-Chemical, Microbiological, And Sensory Characteristics Of Frozen Yogurt, Roberto Antonio Cedillos Hernández

LSU Master's Theses

Frozen yogurts contain yogurt culture bacteria which might impart health benefits to its consumers. Global frozen yogurt market sales are expected to grow 4.8% by 2028 which represents an important opportunity for the industry, consumers, and researchers. Polyphenols are metabolites found in plants which have antioxidant and anti-inflammatory properties and might prevent chronical diseases such as cancer, diabetes, and cardiovascular diseases. The objective of this study was to elucidate the effect of the polyphenol hesperidin on the physico-chemical, microbiological, and sensory characteristics of frozen yogurts. Hesperidin was incorporated in frozen yogurt at three concentrations (500, 250 and 125 mg/90g of …

Development And Characterization Of Physicochemical Properties And Consumer Perception Of Gluten-Free Oat-Based Snack Bars Containing Orange Peel, Andrea R. Muela Negrete

LSU Master's Theses

Orange peel (OP) is a major byproduct from orange juice production, and is a good source of fiber and flavonoids, particularly nobiletin. Nobiletin has been reported to exhibit pharmacological activities including anti-inflammation and antioxidation. Incorporating orange peel into food products would harness economic benefit of this industrial byproduct and support a sustainable food chain. This study was performed to evaluate consumer perception of gluten-free oat-based snack bars (GFOSBs) containing orange peel.

In the first study three GFOSBs were formulated to contain 17%, 20%, and 23% orange peel by weight. Consumers (N=103) evaluated GFOSBs for sensory liking (9-point hedonic scale) and …
