Insecticidal and bactericidal method for nut roasted food

Abstract

The invention discloses an insecticidal and bactericidal method for nut roasted food and relates to the technical field of nut processing. The method comprises the following steps: airing and selecting harvested nut raw materials, freezing, and carrying out insecticidal and bactericidal treatment on the frozen nut raw materials by microwave heating. Before adopting insecticidal and bactericidal treatment by microwave heating, nut raw materials are frozen firstly, so that the problem of heating nonuniformity in the microwave heating process is solved, then microorganisms, worm eggs and other diseases and insect pests in nut fruits are effectively killed, and the killing effect is good; and freezing and microwave heating are combined for insecticidal and bactericidal treatment, so that the microwave treatment time is shortened, and the problems of product discoloration and the like are avoided.

Description

technical field [0001] The invention relates to the technical field of nut processing, in particular to a method for killing insects and bacteria of nut-roasted seeds and nuts. Background technique [0002] Nuts are a category of closed fruits, which have hard skins and contain one or more seeds, such as chestnuts, almonds, etc. Nuts are the essence of plants, which are comprehensive and rich in nutrition, high in protein, oil, minerals, and vitamins, and have excellent effects on human growth and development, strengthening physical fitness, and preventing diseases. Regular food is beneficial to heart disease, cancer, and vascular diseases It has preventive and therapeutic effects, and can also improve eyesight and brain.

Problems solved by technology

[0003] As a kind of agricultural and sideline product, the epidermis and interior of nuts will inevitably be infected with fungal diseases during planting and storage, especially some nuts contain high content of starch, oil and other components, which provide a good living environment for pests and mold. The endogenous eggs of the insects will hatch when the conditions are suitable in the later period, which will cause great losses to the raw materials and products of such agricultural and sideline products

[0004] At present, roasted nuts and seeds and seeds and nuts are mainly used to kill insect eggs in raw materials by means of baking, fumigation, blanching, high-temperature sterilization, and adding preservatives. However, the above-mentioned process often has the following problems: First, it cannot fully kill the eggs inside the raw materials. endogenous insect eggs, which lead to the occurrence of such pests in the process of product storage and circulation, causing serious economic losses; second, it often affects the original flavor and nutritional content of food
