As a highly perishable product, proper handling from capture or farming to the consumer is crucial.<\/p>\r\n<p><u><em>The main shelf life issues include:<\/em><\/u><\/p>\r\n\r\n\r\n\r\n<ul class=\"wp-block-list\">\r\n<li><strong>Rapid decomposition<\/strong>: Without proper refrigeration or freezing, <strong>shrimps <\/strong>begin to decompose within hours.<\/li>\r\n\r\n\r\n\r\n<li><strong>Color changes<\/strong>: Fresh <strong>shrimps <\/strong>have a bright color, but over time and with oxygen exposure, their color can turn dull or gray.<\/li>\r\n\r\n\r\n\r\n<li><strong>Bacterial growth:<\/strong> The presence of bacteria such as <em>Listeria <\/em>or <em>Salmonella <\/em>poses a food safety risk if proper preservation measures are not taken.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">Thus, <strong>shrimp manufacturers<\/strong> resort to the <strong>use of additives and preservatives to maintain the shelf life of products<\/strong> until they reach the end consumer.<\/p>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading has-palm-leaf-color has-text-color has-link-color has-large-font-size wp-elements-75f5b793b43c07cdb17f7a0bdca507b8\"><strong>What additives are commonly used to improve the color and safety of shrimps?<\/strong><\/h2>\r\n\r\n\r\n\r\n<p class=\"wp-block-paragraph\">To preserve both the appearance and safety of <strong>shrimps<\/strong>, the food industry uses various chemical additives and preservatives.
