Baking method for moon cakes and baking equipment

Abstract

The invention belongs to the field of food processing, and specifically discloses a baking method for moon cakes. The method comprises the following steps: baking moon cakes to be baked in an isolatedgas environment composed of a preset gas, and cooling the baked moon cakes in the isolated gas environment. The moon cakes are baked and cooled in the isolated gas environment, the moon cakes are isolated from the air, baking is performed in the oxygen-free environment, so that an oxidation reaction of grease in the moon cakes can be effectively inhibited from generating oxidation deteriorated substances harmful to health; and the moon cakes are baked in the environment isolated from the air, the content of oxygen residues and the oxidation deteriorated substances in the moon cakes is extremely small, the oxygen absorption capacity of the moon cakes is reduced, and the shelf life of the moon cakes is increased by 0.5 time or more. The invention also discloses baking equipment. The bakingequipment includes a baking device and a gas supply device, the gas supply device supplies the preset gas to the baking device to form the isolated gas environment composed of the preset gas in the baking device, the isolated gas environment is isolated from the air, the moon cakes are baked and cooled in the isolated gas environment, the content of the oxidation deteriorated substances and the oxygen residues in the moon cakes is small, and the moon cakes are easier to store.

Description

technical field [0001] The invention relates to a method for baking mooncakes, in particular to a method for baking and cooling mooncakes in an isolated air environment, and baking equipment for realizing the above-mentioned baking method, belonging to the field of food manufacturing. Background technique [0002] As a kind of traditional food, moon cake has various varieties and different flavors, and is deeply loved by people. In order to maintain a good mouthfeel and reduce the amount of preservatives used in existing moon cakes, a large amount of sugar, oil and salt are often added to the cake skin and cake filling, wherein the oil content reaches more than 30%, and the sugar content reaches more than 40%. Instead of water to keep the mooncake moist and soft, improve the taste. The baking of moon cakes is carried out in the air environment, the baking temperature is as high as 180 ℃, and the high temperature of the baking room volatilizes a small amount of metal ion gas...

AI Technical Summary

Problems solved by technology

The baking of moon cakes is carried out in the air environment, the baking temperature is as high as 180 ℃, and the high temperature of the baking room volatilizes a small amount of metal ion gas. The oil and sugar in the moon cake directly contact the oxygen in the air, and the oil is oxidized by high temperature and catalyzed by metal. The hydroperoxidation reaction generates oxidative deterioration substances, and the oxidative deterioration substances promote the high-temperature oxidation of oils, accelerate the oxidation of oils, and generate more oxidative deterioration substances harmful to health, such as trans fatty acids. Oxidative rancidity is easy to occur in the medium, and the shelf life is short
