The primary purpose of freeze drying within the food industry is to extend the shelf-life of the food while maintaining the quality. [1] Freeze-drying is known to result in the highest quality of foods of all drying techniques because structural integrity is maintained along with preservation of flavors. [1]
Drum drying is a method used for drying out liquids from raw materials with a drying drum.In the drum-drying process, pureed raw ingredients are dried at relatively low temperatures over rotating, high-capacity drums that produce sheets of drum-dried product.
Food preservation may also include processes that inhibit visual deterioration, such as the enzymatic browning reaction in apples after they are cut during food preparation. By preserving food , food waste can be reduced, which is an important way to decrease production costs and increase the efficiency of food systems , improve food security ...
A peptide microarray is a planar slide with peptides spotted onto it or assembled directly on the surface by in-situ synthesis. Whereas peptides spotted can undergo quality controls that include mass spectrometer analysis and concentration normalization before spotting and result from a single synthetic batch, peptides synthesized directly on the surface may suffer from batch-to-batch ...
Additionally, the hurdle effect of food preservation, such as by adding lactic acid bacteria and salt to a food product, is illustrated and described. [ 11 ] [ 12 ] [ 13 ] This figure illustrates the pathway of food preservation followed by lactic acid bacteria involving nisin , as well as the pathway of food preservation followed by salt.
In 1993, Bio-Synthesis was one of the first peptide synthesis companies to acquire a Finnigan MALDI-TOF mass spectrometer for the accurate quality control of synthetic peptides produced in-house. In 1994, Bio-synthesis pioneered the use of molecular methods for HLA analysis which is applied in organ matching for transplantation purposes.
The possible peptide that has the most similar spectrum will have the highest chance to be the right sequence. However, the number of possible peptides may be large. For example, a precursor peptide with a molecular weight of 774 has 21,909,046 possible peptides. Even though it is done in the computer, it takes a long time. [17] [18]
An example of a strong alkaline cleaning agent is sodium hydroxide, also called caustic soda. Although sodium hydroxide (NaOH) can cause corrosion on food contact surfaces such as stainless steel, it is the preferred cleaning agent for protein removal due to its efficacy in dissolving proteins and dispersing/emulsifying food soils.
