Regardless of the shape, size, or geometry of the products, the isostatic principle relies on the instant and uniform pressure transmittance throughout food systems [58]. While salt helps preserve food by reducing water content and disrupting microbial cells, it takes very high salt concentrations (around 10% or more) to prevent bacterial growthmuch higher than what is found in most foods you eat. Ya really helped for my project. 11. Salt has been used as a food safety aid since ancient times. Notably, selenium nanoparticles have been extensively studied and successfully applied in various food fields. This is a big drawback of food preservation. Fungi and food spoilage. 2013.

Drying has numerous advantages. The growth of most microorganisms can be prevented or lingered by adjusting storage temperature, reducing water activity, lowering pH, using preservatives, and using proper packaging [28]. These foods are known as semi-perishable. 1st ed. Very few bacteria grow in high salt solutions, so simply adding a very high amount of salt can be an effective method of preservation. Foods can be classified into three major groups based on the extent and purpose of food processing [14]: (a) unprocessed or minimally processed foods, (b) processed culinary or food industry ingredients, and (c) ultra-processed food products. Pectins are complex mixtures of polysaccharides that make up almost one-third of the cell wall of dicotyledonous and some monocotyledonous plants [41, 42].

Pruthi JS. Effectiveness of this method depends on the concentration and selectivity of the chemical reagents, spoilage-causing organisms, and the physical and chemical characteristics of food items [120]. Top 10 food additives to avoid. Freezing slows down the physiochemical and biochemical reactions by forming ice from water below freezing temperature and thus inhibits the growth of deteriorative and pathogenic microorganisms in foods [82, 83].
