Solvent-extracted volatile components from dry powder prepared from Citrus unshiu products such as immature Citrus unshiu (PCU), mature Citrus unshiu (MCU), Citrus unshiu peel (CUP), and citrus juice processing wastes (CJPW), were examined. Also, solvent-extracted volatile components from mushroom mycelia of Pycnoporus coccineus (PC), Lentinus edodes (LE), Pleurotus eryngii (PE), Hericium coralloides (HC), Panellus serotinus (PS), and Ganoderma lucidum(GL), all cultivated using citrus pulp solid media, were assayed. Twenty-nine volatile components were identified in dry powder prepared Citrus unshiu and 18 volatile components were characterized from mushroom mycelia. Of these, ${\beta}-elemene$, germacrene-D, and ${\delta}-cadinene$, were derived from CJPW, but caryophyllene, hexadecanoic acid, decanoic acid, and tetradecanoic acid were synthesized by mushroom mycelia.

The volatile aroma concentrates were isolated from Pleurotus ostreatus by simultaneous distillation-extraction and analyzed by gas chromatography and combined gas chromatography-mass spectrometry. The aroma concentrates obtained had a typical raw or slightly cooked mushroom-like odor, and the yield was 123 ppm. Of 27 components identified, the major components were 3-octanone, 3-octanol, 2-octenal, n-octanol and 2, 4-decadienal, including 1-octen-3-ol contributing 67.06% of the total volatiles, and the $C_8$ compounds comprised about 80% of the total volatiles. On the other hand, the $C_6$ and $C_8$ alcohols in mushroom increased gradually with increase of standing time after homogenation, while aldehydes, ketones, and linoleic acid decreased, and also $C_6$ and $C_8$ compounds were significantly increased when linoleic and linolenic acid were added in homogenates. It appears that most of volatile aroma components in Pleurotus ostreatus were probably produced enzymatically from unsaturated fatty acids containing cis, cis-1, 4-pentadiene moiety.

Sarcodon aspratus (Berk.) S. Ito is a wild mushroom commonly consumed in Korea due to its beneficial effects on health. However, only limited information on the volatile and nonvolatile constituents of S. aspratus is available. In the present study, the total concentration of mushroom soluble sugars, including glucose, trehalose, sucrose, and xylose, was found to be 202.5 mg/kg. The total contents of free and essential amino acids were 2,592.1 mg/kg and 1,249.5 mg/kg, respectively; arginine, lysine, methionine, and valine were the major amino acids present. The contents of total 5'-nucleotides and flavor 5'-nucleotides in S. aspratus were 2,510.7 mg/kg and 773.4 mg/kg, respectively. The volatile components of S. aspratus were collected by simultaneous distillation-extraction (SDE) and analyzed by gas chromatography-massspectrometry (GC-MS). A total of 27 volatile compounds were isolated and identified. The most abundant was l-octen-3-ol, which accounted for more than 68% of total volatiles; other important compounds were 2-octen-1-ol, 1-octen-3-one, and 2-octenol. Our results provide preliminary data for the development of S. aspratus as a food material.

Nutritional and functional components, such as approximate, and volatile flavor compounds, ergosterol and proximate analysis of artificially cultivated Neolentinus lepideus were analyzed. The common elements of N. lepideus were analyzed to have 6.3% crude ash, 19.1% crude protein, 1.9% crude fat, and 8.9% crude fiber, respectively. The volatile flavor compounds of N. lepideus were characterized as 3-Octanone, 3-Octanol and 1-Octanol. The ergosterol content of N. lepideus was shown to be 145.9 ppm.

Flavor-related components were analyzed for dried oak mushrooms (Lentinus edodes) when subjected to ethylene oxide and gamma energy. Volatile flavor components identified by GC and GC-MS were composed primarily of l-oden-3-ol (72.8%), 3-octanone (11.5%) and dimethyl disulfide (6.7%). Most of volatile components were shown labile to the standard cycle of ethylene oxide and 5 kGy-gamma energy, while insignificant changes were observed in the contents of free sugars (mannitol, arabitol, trehalose) and free amino acids. Instrumental analysis have shown, however, that the deterimental effects on flavor-related components were more apparent in EO-fumigated groups than in gamma-irradiated ones, even though the organo-leptic test revealed no significant differences between treated samples and the corresponding control.

The composition of two Bokbunja (Rubus coreanus Miquel) wines (one without mushroom extracts (wine A) and the other is with the extracts (wine B)) has been investigated to improve the quality of Bokbunja wine. The content of solid particle, acidity, crude ash, crude protein of the wine A were 10.5%, 1.36%, 0.45% and 0.05% and those of wine B were 7.4%, 0.54%, 0.31%, and 0.22%, respectively. Crude fat and crude fiber were not detected in both samples. To verify the flavor quality of Bokbunja wine, the volatile components from ethylether extracts of two wines were analyzed using GC/FID and GC/MS. A total number of 12 volatile flavor compounds (6 alcohols, 3 ketones, 1 acid, 1 ester and 1 anhydride) were identified in the two Rubus wines. The major volatile compounds of the wines were 2,3-butanediol, 2,5-furanedione, phenylethyl alcohol, and butanedioic acid and they might affect the major role in the unique flavor of Bokbunja wines.
