Storage common problems

Chemical reaction or polymerization High-temperature coking Corrosion Buildup on internal reactor surfaces, and in crude-oil storage tanks, is often encountered Carbonaceous material is deposited on walls of furnace tubes Common problem in heat exchangers...

The most common problem occurring during flavor storage is deterioration due to oxidation. Any flavoring containing citrus oils or oils based on aldehydes is susceptible to oxidative reactions and development of off-flavors. Thus, an important function of an edible film is protection of the flavoring from oxygen. 

Of all the enzymes of the carnitine biosynthetic pathway, yBBH is the best-studied enzyme. Like e-N-trimethyllysine hydroxylase, y-BBH is a non-heme ferrous-iron dioxygenase that requires a-ketoglutarate, Fe and molecular oxygen as cofactors. In this class of enzymes, the hydroxylation of the substrate is linked to the oxidative decarboxylation of a-ketoglutarate. Ascorbate is needed to maintain iron in die reduced state. yBBHhas been isolated from various sources including human kidney, " catf and rat liver and the bacterium Pseudomonas AKl. A common problem in the purification of this enzyme from mammalian tissues is the poor stability of the protein. We, therefore, determined the optimal storage conditions and subsequently pmified ybutyrobetaine hydroxylase from rat liver. 

One of the most common problems associated with competitive binding assays is the decomposition of the radidoligand during shipping or prolonged storage. Although this is less troublesome with radiolabeled amino acids, it can be particularly... 

A common problem met in factories using chemicals is where to store flammable solvents. Whether in drums or in bulk, outside storage has the advantages that it ... 

Particle flow could be driven by gravity or external forces. Particle discharge from silos or hoppers is an example of particle flow under gravity. Common problems in such plants are nonuniform and/or the interruption of flow from the discharge orifice in the hopper or converging section beneath a storage vessel for powders. DEM simulations have been extensively used to study such systems [61-66]. 

Condensation on the iimer surface of the film is a common problem with MAP and it severely affects the quahty of highly respiring commodities. Condensation takes place due to temperamre fiuctuation in the storage space, a temperature drop of only 0.2°C can cause condensation and temperamre fluctuations in cold stores in this range is quite normal. Tano et al. observed that the quality of mushroom, broccoli, or mature green tomatoes in MAP was severely affected by storage temperamre fluctuation (2007).
