Beef-like cells

Furfiirylthiol is a key flavour especially for coffee, beef and roast-like food aromas. It was synthesised in concentrations of up to 1 g L using /1-lyase activity of whole bacterial cells, e.g. Enterobacter cloacae or Eubacterium limosum [256] (Scheme 23.21). Resting cells were used to cleave the sulfur-carbon bond of a furfural-cysteine conjugate and an XAD-4 resin connected to the gas outlet... 

In recent years, the addition of tallow has moved directly to dairy and beef feed lots. Small, heated, insulated tanks have been developed to receive and hold fat shipments (Figure 7). As described earlier, beef tallow is the most compatible fat for ruminants. It may be sprayed or flowed, at 2-3% of dry matter onto rations of chopped hay, other roughages, grains, or concentrates while in the mixer, or top-dressed on hay or other forages. Feed mixing operations like these require a positive displacement pump, like a Moyno or gear pump with variable-speed drive set to deliver a known amount of fat within a specific time period. As an alternative, mixers in feed mills can be mounted on load cells and equipped with controllers to stop the flow of fat when the desired weight has been added.
