Food and Machinery
Based on the recent reports from domestic and foreign researches, this study elaberated plant food by-products processed by solid-state biotransformation for the enzyme production efficiency and its potential applications. In addition, this study also reviewed solid-state biotransformation on the influence of major biological compounds (e.g., phenolics, flavonoids, polysaccharides etc.) and bio-activities of plant food by-products, and prospected its direction for future development.

Objective: This study aimed to improve the technological conditions of antioxidant activity of pumpkin polysaccharide. Methods:The effects of temperature, pumpkin powder/distilled water ratio of solid to liquid, inoculation amount and shaking speed on the extraction rate of bio-transformed pumpkin polysaccharide were investigated, and the scavenging ability of pumpkin polysaccharide on DPPH free radical was studied. Results:The optimal conditions were inoculation amount 1% and solid-liquid ratio 1∶30 (g/mL), with shaking speed of 100 r/min at 37 ℃. Under the control of these conditions, the scavenging rate of DPPH free radical was (54.61±1.58)%. The in vitro antioxidant activity of the …
Performance Of A Temperate-Zone Channel Catfish Biofloc Technology Production System During Winter, Bartholomew W. Green
Performance Of A Temperate-Zone Channel Catfish Biofloc Technology Production System During Winter, Bartholomew W. Green
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
Channel catfish (Ictalurus punctatus) have been grown successfully in an outdoor biofloc technology production system. Outdoor biofloc production systems in the tropic sare operated year-round, whereas the channel catfish studies were conducted only during the growing season and biofloc production tanks were harvested and idled for the winter. If an outdoor biofloc production system is to be adopted by farmers at temperate latitudes, then data gaps related to system and fish performance over the winter must be addressed. The present study was conducted to address these data gaps for channel catfish culture. Waters from a recently completed biofloc …
