Problems solved by technology

[0002] Cake molds are an indispensable tool for baking. At present, cake molds are made of metal and silicone materials. Metal cake molds can be used in the oven, but they will be limited in microwave ovens, and the temperature of metal molds after heating Higher, prone to burns; silicone cake molds are now gradually rising, and are more and more popular with consumers. They are high temperature resistant, easy to clean, soft and comfortable, and have various colors, but they have no antibacterial properties and are easy to breed bacteria. The mold is easy to mold. It will also shorten the shelf life of the cake

Abstract

The invention mainly relates to the technical field of food material processing, and discloses a high temperature-resistant and antibacterial silica gel cake mold. The high temperature-resistant and antibacterial silica gel cake mold is made from silicone rubber, natural rubber, hydroxypropyl cellulose, zeolite powder, fumed silica, chitosan and nano-silica. The high temperature-resistant and antibacterial silica gel cake mold has the advantages of simple raw materials, low price, tolerance of the temperature of -70-260 DEG C, good safe and healthy property, no production of any toxic components through leaching and high flexibility, has a tensile strength reaching 12.4-12.6 MPa, has an antibacterial rate reaching 87.9%, and has significantly enhanced use performances; the silicone rubberis gradually melted, and then the chitosan is added to modify the silicone rubber in order to improve the antibacterial property of the silicone rubber, so mildews of the mold and bacterial growth ofa cake are avoided, and the shelf life of the cake is prolonged; and the natural rubber is melted, then the fumed silica is added, and vacuum stirring is performed to modify the natural rubber, so thehigh temperature resistance and the flexibility of the natural rubber are improved.

Description

Technical field [0001] The invention mainly relates to the technical field of food material processing, in particular to a high temperature resistant antibacterial silica gel cake mold. Background technique [0002] Cake molds are an indispensable tool for baking. At present, cake molds are made of metal and silicone materials. Metal cake molds can be used in the oven, but they will be restricted when used in a microwave oven, and the temperature of the metal mold after heating High, easy to burn; silicone cake molds are now gradually emerging, more and more popular with consumers, high temperature resistance, easy to clean, soft and comfortable, diverse colors, but not anti-bacterial, easy to breed bacteria, mold easy to mold, It will also shorten the shelf life of the cake. Summary of the invention [0003] In order to make up for the defects of the prior art, the purpose of the present invention is to provide a high temperature resistant antibacterial silicone cake mold.
