You have rated this. About the Drink. Tizer is a red fizzy drink made by Barr (the makers of Irn Bru) from Scotland. The drink was first made in 1924 by Fred Pickup of Manchester when it was known as âPickupâs Appetizerâ and was eventually sold to Irn Bru in 1972 for Â£2.5 million.ut then they changed it to the tizer we have nowadays. It now tastes disgusting and leaves a horrible feeling in your throat. Iâm 18, Iâve still got along time ahead of me to see the old tizer maybe return one day. It was my favourite pop of all time.
Ricin (/ËraÉªsÉªn/ REYE-sin) is a highly toxic, naturally occurring lectin (a carbohydrate-binding protein) produced in the seeds of the castor oil plant, Ricinus communis. A dose of purified ricin powder the size of a few grains of table salt can kill an adult human. The median lethal dose (LD50) of ricin is around 22 micrograms per kilogram of body weight if the exposure is from injection or inhalation (1.78 milligram for an average adult).
The filtrate from the water extraction step, which contains the ricin, was treated with a 16.7% solution of Na SO to precipitate the protein. This solution is com- ice posed of 20 pounds of salt in 100 pounds of water and the amount used was such that the salt content equalled 20% of the filtrate weight.
