'Gala' is an apple cultivar with a distinctive aroma and flavor. 'Gala' storage season is short in regular atmosphere (RA). Controlled atmosphere (CA) extends 'Gala' storage but volatile production is reduced. 'Gala' odor-active aroma compounds were identified using Osme, a gas chromatography and olfactometry technique. Changes in aroma after RA...

commercial brands of pre-stirred yogurt. Once the consumer and
descriptive panel data was collected, the data was combined to
determine the interrelationship of these two sets of data and to
determine the...
Historically, brewers have used dry-hopping (a cold extraction of nonvolatile and volatile chemicals from hops into fermenting or finished beer) to increase the microbial stability and shelf life of their beer. As hoppy beer styles have gained in popularity over the last decade (2007-2017), the objective of dry-hopping has turned...

market share in Asia to Canada and Australia....
Addition of acids to foods allows for enhanced food safety. Acids are the primary form of defense against microbial contamination in refrigerated foods, while use of acids in conjunction with heat or high hydrostatic pressure processing lowers energy usage resulting in cost reduction. However, addition of acids to food or...
'Marion' blackberry is known for having excellent aroma and flavor, yet they are susceptible to damage by freezing and they are very thorny. Thornless blackberry cultivars have been developed and show great potential. Thus, the interest of the study was in determining which of eight thornless blackberry cultivars, have similar...
Hops contribute many desirable aromas to beer. Traditionally hop aromas have
been described by the point of addition in the brewing process (dry-hop, finish-hop, or
kettle-hop). The compounds present in the oil provide a wide range of aroma qualities.
Since the composition of the oil is different for each hop...
The effect of sweeteners on fruit flavor perception was studied
through the use of fruitiness power functions for unsweetened and
sweetened model systems. In the first part of the study, two
isosweet concentrations of aspartame and sucrose were determined
and combined with five concentrations of orange and strawberry
flavorants. Fruitiness...
