The word "luncheon meat" comes from abroad with different opinions, but it is generally called "luncheon meat" because it is a fast food side dish at lunch. Breakfast and dinner are more formal and are usually eaten at home, so you can't eat such fast food. Origin 1: Because everyone in Hong Kong was so busy in the 1980s, many people took lunch meat as lunch to save time. In the past, foreigners didn't go to teahouses or tea restaurants to eat fast food like Hong Kong people, but stayed in the company for lunch. However, because the company can't cook and the lunch time is not long, most employees will make sandwiches for lunch. At that time, many employees liked to put meat slices in sandwiches, and they generally didn't eat these sandwiches for breakfast or dinner. Over time, the meat sandwiched between sandwiches is called "lunch meat". Origin 2: 1937, American Jay homer invented a food called Spam, which means canned food with spices and ham. At that time, lunch was only common in the middle class and upper class, and the general working class did not have the habit of eating lunch. However, at the luncheons held by government officials and company executives, spam became very popular, and the word lunch meat gradually appeared. When Spam was introduced to Chinese mainland, canners translated Spam into lunch meat based on lunch meat, which became the origin of the word lunch meat. Lunch meat and ham sausage are somewhat similar, but there are also differences. Specifically, ham sausage and lunch meat are high-temperature meat products with similar basic formulas. The formula of lunch meat is basically the same, because it is a unified standard, regardless of grade. However, the formula of ham sausage is quite different, which is divided into super sausage, excellent sausage and ordinary sausage. The meat content of products with different standards varies greatly. The meat content of lunch meat is about the same as that of fine sausage.
