Cryopreservation is an effective way to transport biological samples over long distances, store samples for prolonged periods of time, and create a bank of samples for users. Molecules, referred to as cryoprotective agents (CPAs), are added to reduce the osmotic shock and physical stresses cells undergo in the freezing process. [ 2 ]
Examples of hurdles in a food system are high temperature during processing, low temperature during storage, increasing the acidity, lowering the water activity or redox potential, and the presence of preservatives or biopreservatives. According to the type of pathogens and how risky they are, the intensity of the hurdles can be adjusted ...
Food rotation is important to preserve freshness. When food is rotated, the food that has been in storage the longest is used first. As food is used, new food is added to the pantry to replace it; the essential rationale is to use the oldest food as soon as possible so that nothing is in storage too long and becomes unsafe to eat. Labelling ...
A collection of mason jars filled with preserved foods. Package sterility and seal integrity are vital for commercially packaged shelf-stable food products. With flexible packaging (plastic films, foils, laminates, etc), the choice of materials and process conditions are an important decision for packaging engineers.

Zygosaccharomyces is a genus of yeasts in the family Saccharomycetaceae.It was first described under the genus Saccharomyces, but in 1983, it was reclassified to its current name in the work by Barnett et al. [1]
Exposure to toxic molds can cause adverse health effects in the short- and long-term, per the World Health Organization. The most dangerous type are aflatoxins, which can be carcinogenic to humans ...
Saccharomyces cerevisiae, the yeast commonly used as baker's yeast. Gradation marks are 1 μm apart.. Baker yeast is the common name for the strains of yeast commonly used in baking bread and other bakery products, serving as a leavening agent which causes the bread to rise (expand and become lighter and softer) by converting the fermentable sugars present in the dough into carbon dioxide and ...
