The invention discloses a gas mixture for keeping freshness of a fresh barbary wolfberry fruit and a fresh keeping method of the fresh barbary wolfberry fruit. The gas mixture for keeping freshness of the fresh barbary wolfberry fruit is composed of the following components by weight percentage: 85-96% of nitrogen, 1-10% of carbon dioxide and 1-6% of oxygen. The fresh keeping method of the fresh barbary wolfberry fruit comprises the following steps: putting the fresh barbary wolfberry fruit in a packaging container, introducing the gas mixture into the packaging container and storing at the temperature of 4 DEG C. By adopting the gas mixture provided by the invention, the freshening time of the fresh barbary wolfberry fruit is prolonged; the fresh barbary wolfberry fruit can be stored in the gas mixture for 3-4 days under room temperature and can be at least stored for 20 days at the temperature of 4 DEG C.
Description
technical field [0001] The invention relates to the field of fruit preservation, in particular to a gas mixture for preserving fresh wolfberry fruit and a method for preserving fresh wolfberry fruit. Background technique [0002] Lycium barbarum, a Solanaceae plant, is a plant with the same source of medicine and food. Fresh wolfberry fruit is rich in functional ingredients such as wolfberry polysaccharides, carotenoids, and betaine, which have the functions of promoting metabolism, scavenging free radicals, lowering blood sugar and blood lipids, and anti-cancer. At present, goji berries are mainly dried. Common goji berries are dried goji berries that have been dried, dried or soaked, which will lose the active ingredients of fresh goji berries. Studies have shown that the nutritional value of fresh wolfberry fruit is much higher than that of dried fruit wolfberry. At the same time, with the development of the economy and the continuous change of consumption concepts, peo...
