Fishmeal is widely used in the feed industry as main protein material. The freshness grade directly affects quality of fishmeal. During storage fishmeal, odor would change accordingly grades decreased. To study characteristic volatile organic compounds (VOCs) stored at 25 °C and 80%RH with different grades, headspace solid-phase microextraction combined gas chromatography-mass spectrometry (HS-SPME-GC-MS) was to analyze. single-factor test chosen for 50/30 μm...
Headspace solid-phase microextraction, combined with gas chromatography–mass spectrometry and partial least squares discriminant analysis, was adopted to study the rule of change in volatile organic compounds (VOCs) for domestic imported fishmeal during storage different freshness grades. The results showed that 318 kinds VOCs were detected fishmeal, while 194 fishmeal. total relative content increased time, among which acids nitrogen-containing significantly, esters ketones slightly,...
The airflow dynamics within hammer mills' crushing chambers significantly affect material and screening. Understanding the mechanism necessitates studying distribution. Using a self-built test platform computational fluid (CFD) simulations, we investigated impact of screen aperture size, rotor speed, hammer-screen clearance, quantity, mass flow rate on distribution region, circulation layer, apertures. Results indicated generally uniform axial static pressure with radial gradients. Increased...
To explore the effect of storage conditions on freshness fishmeal, acid value (AV), volatile basic nitrogen (VBN), and pH were used as evaluation indexes to changes in during influence mold count these indexes. The effects temperature relative humidity (RH) AV, VBN, value, studied using a single-factor test, grey relation analysis (GRA) was assess association between appropriate determined technique for order preference by similarity ideal solution (TOPSIS) method, which provides theoretical...
