According to foreign media BGR, recently, some researchers have found that the pots found in some archaeological sites may contain clues to reveal ancient cooking habits. The research found that these jars hold the chemical signals of the food cooked inside, even after multiple meals. A team of researchers at the University of California, Berkeley, wanted to find out if ancient tableware had any clues that had not yet been discovered. < / P > < p > it was found that certain types of ancient cooking utensils, especially unglazed ceramic pots and bowls, absorbed chemical signals from the food cooked inside. The study, published in the scientific report, suggests that people may be able to learn about ancient cooking habits by digging through recognizable traces in tableware. < / P > < p > to determine how much information ancient dishes might hold, the team spent a year cooking dozens of meals in fresh, unglazed jars similar to those used long ago. They recruited chefs to prepare meals including venison (donated from roadside stalls), corn and wheat, and then hunt for chemical signatures after the pots are emptied. < / P > < p > The aim of the study was to determine how much information was contained in these Kitchenware and whether a meal could effectively erase any previous meal. It turns out that this is not the case, and the pots serve as a timeline to reveal the history of the food cooked in each container. < / P > < p > “our data can help us better reconstruct the meals and specific ingredients people ate in the past, which in turn can reveal the social, political and environmental relationships in ancient communities,” Melanie Miller, co-author of the study, said in a statement. < / P > < p > the researchers were able to identify specific areas of the pot that revealed the cooking of the last meal, while other areas revealed past meals. The researchers explained: < / P > < p > our results show that: (1) The composition of carbonized macro residue represents the final food cooked in utensils; (2) the thin layer of copper rust residue represents the mixture of previous cooking events and tends to be the final product cooked in the pot; (3) the absorbed lipid residue is formed in multiple cooking events and gradually replaced with time, and there is little evidence of final formula composition.
