In another embodiment, the flavoring composition comprises a mixture containing reduced (rho-) iso-α-acids in alkali metal salts form, β-acids and hop oil. This latter composition is useful as a substitute for normal kettle extract, hops or hop pellets, allowing easy preparation of beer that...
We conclude that the alkaline labile lesions observed in DNA at the bipyrimidine sites are the same as those that yield the 6-4 products upon acid hydrolysis of DNA. The mechanisms for the formation and the consequences of DNA structure for these lesions as well as the possible biological ...
In addition to consideration of the role of irritation inhibitors, our analysis of the QPCC data led to the following definitions: 1) an alkaline cleaning product is corrosive if its pH is 13.0 or greater, or if 10.5 陇 pH < 13.0 and the alkali reserve is 10 or greater for solids or ...
