Inhibitors. Sugar is used in large quantities in fruit jams as a preservative. The strong sweetness, however, prevents fruity flavors from being noticed. For these and other foods that must use a large amount of sugar for purposes other than sweet taste, there is need for a sweet-taste inhibitor. 

Fruity flavor in dairy products is the result of ethyl ester formation, usually catalyzed by esterases from psychrotrophic or lactic acid bacteria. Ester formation by P. fragi involves liberation of butyric and ca-proic acids from the one and three positions of milk triglycerides and the subsequent enzymatic esterification of these fatty acids with ethanol (Hosono et al. 1974 Hosono and Elliott 1974). Consequently, among the esters formed, ethyl butyrate and ethyl hexanoate predominate. Pseudomonas-produced fruity flavor can occur in fluid milk, cottage cheese, and butter. 

Fruity flavor in Cheddar cheese is also associated with high levels of ethyl butyrate and ethyl hexanoate (Bills et al. 1965). However, this defect is usually caused by esterase activity from lactic acid bacteria, especially S. lactis and S. lactis subsp. diacetylactis (Vedamuthu et al. 1966). Fruity-flavored cheeses tend to have abnormally high levels of ethanol, which is available for esterification (Bills et al. 1965). Streptococcal esterase activity in cheese is affected by the level of glutathione, which suggests a dependence on free sulfhydral groups for activity (Harper et al. 1980).

Furan-3,4-diol derivatives are often written in the monoenolic form which is believed to be the parent nucleus of several important compounds responsible for the flavorings of various foodstuff s. The 2(5)-methyl derivative (56) has been detected in both soy sauce140 and beef broth.141 Related compounds occur in coffee and onion. The chief member of the series, furaneol (57), has a fruity flavor when dilute, changing to caramel as the concentration increases.107 The substance isolated from the nonenzymatic browning" of... 

Esters. Esters are extremely important aroma compounds and there are many reports that esters are biosynthetic products of bacterial action. Thus, the fruity flavor defect sometimes found in cheddar cheese is due to the presence of esters, principally ethyl butyrate and ethyl caproate (25). Similar esters can be found in beer in which both fusel alcohols and the short chain fatty acids, acetic and butyric, are also present. These materials can undergo esterification, which in this case is mediated by the enzyme alcohol acetyltransferase present in the yeast used for beer fermentation (26). There are a number of esters present in wine which are metabolically produced by the yeast. Of these,... 

This beer took the Best of Show award at the 1991 Maine Common Ground Fair over 219 other entries. Judges said, Nice all-around aroma. Clear, bright, can t fault appearance. Good malt and hops, nutty fruity flavor. Could use more flavor hops. Body nearly right on. Very nice and very drinkable. ... 

Spadone et al. (1990) also identified aliphatic unsaturated aldehydes, long-chain 2-alkanones, lactones and esters which are only present in green coffee and would give the beans the characteristic soapy, fatty and fruity (coconut, peach, apricot) notes. They were the first authors to find (3-damascenone (Section 5,D.38) in raw coffee, a compound that resists roasting and contributes highly to the tea-like and fruity flavor of the beverage,... 

The (/i,/T)-isomer is described with green, fatty, fruity flavor (Chemisis, 1972). 

It has a fatty, green, fruity flavor with a fenugreek, fruity odor (Chemisis, 1974). 

It has a sweet, roasted odor (Sakaguchi and Shibamoto, 1978b). At a concentration of 30 ppm it was perceived as having a caramel, sweet, creamy, fruity flavor (Chemisis, 1998). 

Orris derivatives are used in expensive perfumes for their delicate, violetlike, woody aromas. In flavors, orris derivatives are mainly used to modify fruity flavors. In both types of applications, orris derivatives are formulated at extremely low levels, where they still bring warmth and diffusiveness. Their price is very high. However, as far as they are formulated in extreme dilution, they are still cost effective and in strong demand by perfumers and flavorists. The orris products family is characterized by a rather simple process flow chart (Figure 2). Two sources of orris raw materials are processed ... 

Sensory evaluations of the treated wine and fruit juice compared to the control were conducted. 9 of 10 judges identified correctly the treated Muscat wine and found a significant increase in the flavor and a richer Muscat flavor. 10 of 10 judges correctly identified the treated Apricot juice. In many cases, treated juice were prefered, in particular because of an intense fruitiness flavor.

Thermal degradation can also cause IV loss, color generation, and acetaldehyde production. For colorless bottles, any color is bad. AA has a fruity flavor that can affect product quality because it is very potent at small concentrations. As shown in Fig. 12.18, as temperature goes up, haze decreases and acetaldehyde concentration increases. 

Passion fruit Red Rf. (Passiflora edulis) . The flowery-fruity flavor is due in particular to (Z)-3-hexenyl esters, (Z)-3-octenyl acetate, citronellyl and geranyl acetate. Yellow P.f. (P. edulis flavicarpa). 2-Methy 1-4-propyl-1,3-oxathiane, 3-mercapto-l-hexanol (CjHuOS, Mr 134.24, CAS [51755-83-0]) and the corresponding esters are mainly responsible for the exotic-fruity flavor. In both sorts about 30 Cu-noriso-prenoids, including fl ionone, )3- damascenone and edulane (2,5,5,8a-tetramethyl-l-benzopyran) make major contributions to the aroma.
