Changes of headspace volatile components of soybeans during roasting.

Kinetic Modeling of Mass Transfer During Roasting of Soybeans Using Combined Infrared-Hot Air Heating

ABSTRACT: Roasting is one of the widespread methods for processing of nuts and beans that significantly enhances the flavor, color, texture and appearance of the products. In this research the kinetics and modeling of soybean roasting using combined infrared-hot air system and consumption of energy were investigated. The effect of the hot air temperature (160, 180 and 200 ºC), infrared powers (...

Analysis of the volatile components of brown coal distillate using the headspace extraction-GC-MS

The headspace extraction-GC-MS was used to separate and identify the volatile components of brown coal distillate(BCD)in this paper, while the retention index (RI)was verified using the C8-C40 n-alkane mix standard. There were 15 kinds of volatile components of BCD which had been identified; the main ingredients included acids, alcohols, esters, ketones, etc. And the quantity of each component ...

Changes in Seed Sugar Pools during Roasting of Different Peanut

Headspace solid-phase microextraction analysis of volatile components in Narcissus tazetta var. chinensis Roem.

The volatile components in single-flowered and double-flowered Chinese narcissus were identified by headspace-solid phase microextraction (HS-SPME) coupled with GC and GC/MS. Changes in aroma during the vase-life (days 0, 1, 2, 3, 4, 5 and 6) of two samples were also studied. A total of 35 compounds were identified, of which all were present in single-flowered and 26 in double-flowered samples....

Headspace solid-phase microextraction analysis of volatile components in Phalaenopsis Nobby's Pacific Sunset.

Phalaenopsis is the most important economic crop in the Orchidaceae family. There are currently numerous beautiful and colorful Phalaenopsis flowers, but only a few species of Phalaenopsis have an aroma. This study reports the analysis volatile components present in P. Nobby's Pacific Sunset by solid-phase microextraction (SPME) coupled with gas chromatography (GC) and gas chromatography/mass s...
