It is eaten plain as part of the traditional Turkish breakfast, used in salads, and incorporated into cooked foods such as b?rek, pide, menemen and also used for some traditional desserts. There are several types of cheeses with different characteristics and aroma compounds, and they can be used for preparation of various foods as an additive. The formation of cheese aroma basically associated with lipids, proteins and lactose content of milk, besides raw or pasteurized milk, starter or non-starter bacteria, ripening conditions. Cheese flavoring agent is used in a variety of products such as salads, pizza, breads. General properties of some traditional Turkish cheeses, their aroma compounds and importance for Turkish cuisine are discussed.展开更多

The results showed that the optimal retention time of the heating up of capillary columns was 5 min. Of the seven fibers used in this work,DVB/CAR/PDMS was found to be the most suitable to extract the aroma volatile compounds in Fuji apple. A total number of 43 volatile compounds were identified according to their retention time on capillary columns and their mass spectra,including eleven esters,ten alcohols,ten aldehydes,seven alkenes,two anhydrides,one ketone,one phenol and one ether. This detection method will provide a new foundation for analysis of volatile compounds in apple were identified.展开更多

The results showed that, 29 kinds of compounds were identified from the aroma components in ‘Changping 8’ apple fruit, and they were aldehydes, alcohols, esters, ketones, etc. The main aroma components of apple fruits were acetic acid, hexyl ester, acetic acid, butyl ester,(E)-2-hexenal, 1-butanol, hexanal, and 1-hexanol.展开更多
