Long-term preservation

Before the fibers can be spun into yams, a certain amount of preparation is necessary for cleaning and removal of undesirable accessory materials such as fat, wax, gum, or pulp. The weighting of sUk is a process to counter the weight loss resulting from degumming the fibers using heavy metal salts of tin or bismuth. This process affects the durabUity and long term preservation.

Storage of printed carbohydrate and protein microarrays The arrays are usually air dried and stored at room temperature. For long-term preservation, the chips can be sealed in a plastic bag with desiccant and stored at 4°C.

The enantiomeric excess of several a-alkyl amino acids from the Murchison meteorite has been measured by Cronin and Pizzarello [69-71], who found significant values (1 -15% ee l). Conversely to previous estimates often biased by terrestrial contamination, these results can be considered as reliable since target AA are both non-biogenic and non-terrestrial in origin (the latter confirmed by D/H and 13C/12C isotopic ratios). The quaternary a-carbon prevents the racemization of the compounds, thus allowing the long-term preservation of the enantiomeric excess. 

A method for producing noodles using a fine powder prepared from Jerusalem artichoke is given. The noodles have better long-term preservation and benefit from having inu-lin, vitamins, and minerals from Jerusalem artichoke.
