Chokeberry Juice

Aronia melanocarpa (Michx.) Elliott commercial products (dried fruit, juice and compote) were analyzed for their polyphenol content by chromatographic and spectrophotometric analyses in order to ascertain the fate of this group of compounds when fresh fruit is processed and sold in different forms on the market. Different classes of polyphenols were investigated: hydroxycinnamic derivatives ranged from 0.65 mg/g to 4.30 mg/g, flavonoids from 0.36 mg/g to 1.12 mg/g, and anthocyanins from 0.65 to 7.08 mg/g sample. 4- O-Caffeoyl-quinic acid was tentatively identified for the first time in Aronia. In order to characterize better chokeberry juice, a GC profile of aroma compounds was obtained. The aroma juice compounds belong mainly to the chemical classes of alcohols (48.9%) and ketones (30.28%). The most abundant compound is 3-penthen-2-one (23.6%).

Specific Food

Rendang is a traditional-specific food in Indonesia. Rendang is generally made with beef, coconut milk, and spices. There are two types of rendang according to its time processing. Rendang “kalio” is a final product of rendang that needs a short heating period while dried rendang is produced by the longer heating period. In the present study, the profile of the volatile compounds that most obtained from spices was analyzed by gas chromatography-mass spectrometry (GC-MS) to characterize the influence of the cooking period on the flavor characteristic of two available types of rendang. There were dozens of volatile compounds identified including carboxylic, aromatic, carbonyl, and alcohols where carboxylic and aromatics were the predominant volatile fractions. The results indicated that the cooking period affected the profile of volatile compounds between "kalio" rendang and dried rendang. Carboxylic and aromatics were less in the dried rendang compared to the rendang “kalio” where others were opposites. The increase of carbonyls and alcohol during the cooking process has suggested can play a crucial role in the flavor of dried rendang.

Abstract The detection and identification of substances that give rise to aromas and off-odors is often a difficult task. Perception of odors is very subjective and odor detection thresholds vary from person to person. The identification of trace levels of compounds responsible for perceived odors is difficult using conventional analytical tools. This paper will focus on a novel method for sampling and analyzing aromatic volatile compounds using an analytical system specifically designed for odor analysis.
