I tend to steer well clear of shop brought sandwiches because they are often not only tasteless but also full of preservatives. For these reasons I prefer to buy fresh bread in the morning and make my sandwiches on the day I want to eat them. This new idea, then is probably not for me. According to the article scientists have found a way to make a sandwich last longer. The concept which is likely to be rolled out across convenience stores means a sandwich can be keep “fresh” or edible at least for anything up to two weeks. The sandwiches have a shelf life of 14 days and supposedly taste as good on day 14 as they do on day one of being made. Launched by Booker, the secret is to suck all of the oxygen out of the packaging. The fillings are also preserved with a slightly acidic mayonnaise which acts as a preservative. The flavours available will include chicken tikka, chicken and bacon, tuna mayonnaise and cheese onion which will all be available on oatmeal bread. They will be aimed at the budget shopper with a price tag of £1.49 per packet.
