Potential use of the high protein by-product of beer production from 77% sorghum malt and 23% maize grit was investigated. Red sorghum spent grains (RSSG) and white sorghum spent grains (WSSG) contained 23.4 and 19.3% crude protein (CP), 54 and 43% dietary fiber (NDF), 1.44 and 0.78% ash, 4.5 and 3.2% hexane extract and tannin content of 7.5 and 1.0 mg/g catechin equivalent respectively. Magnesium was the most abundant mineral in both RSSG and WSSG--185 and 140 mg/kg, respectively. Calcium, zinc, iron and copper were generally low. Both samples contained cadmium 1.12 (WSSG), 1.19 (RSSG) and lead at 1.38 mg/kg. Lysine was the limiting amino acid (chemical score 0.55) in both samples. Other essential amino acids were adequate or surplus. Stearic acid was the predominant fatty acid with varying levels of lauric, myristic, palmitic, and oleic acids in both samples. Feed intake and weight gain were highest in rats fed 26.3% WSSG (contributing 50% of the diet protein) but protein efficiency ratio (PER) and net protein retention (NPR) were highest in diets where spent grains contributed just 25% of the diet protein. True digestibility of diets decreased as dietary fiber content increased such that animals on diets containing 100% spent grain protein (above 20% NDF) lost weight.

Using a portable gas chromatography and mass spectrometry (GC-MS), the volatile organic compounds (VOCs) pollution in each unit of the wastewater treatment system for vitamin C production was studied, and the species characteristics of volatile organic compounds (VOCs) were analyzed and summarized. The results showed that 32 kinds of volatile organic compounds were identified, and the total mass concentration range of volatilizing VOCs was 0.9629-32.0970 mg x m(-3). The most species and the largest concentration (25 and 32.0970 mg x m(-3)) of volatilizing VOCs were found in grit chamber, which was located in the most front-end of the wastewater treatment system and was in semi-closed state. The proportion of molecular sulfide in the grit chamber was as high as 30.02%; Higher proportions of aromatic hydrocarbons were monitored in the subsequent processing units, with percentages of 21.06%-31.48%. The main types of VOCs monitored were chlorinated hydrocarbons and ketones, accounting for 6.39%-55.80% and 10.40%-58.08% of the total amount, respectively; 14 kinds of VOCs were detected in every unit of the wastewater treatment system: acetone, 2-butanone, n-hexane, chloroform, chlorobenzene etc, among which, vinyl chloride, styrene and 1,3-butadiene belong to the highly toxic substances. The vinyl chloride concentration exceeded the standard of "atmospheric pollutants emission standards" (GB 16297-1996), while 1,3-butadiene and other pollutants have no national standard limits. The results of this study provide a scientific basis for the revision of China's pharmaceutical wastewater VOCs emission standards.
