Perfection of the Technology for Production of Canned Apple Compotes Using Secondary Resources and Intensive Sterilization Regimes

Resumo

This paper presents the results of research on improving the technology for production of canned apple compotes using secondary products after cutting and cleaning fruit for syrup boiling and intensive heat sterilization based on the use of new techniques—preliminary heating of fruit in cans in the ultrahigh frequency electromagnetic field with sterilization under intensive regimes with the use of high-temperature heat carriers and rotation of the cans during sterilization. It is established that the use of the resulting infusion of secondary products for syrup boiling provides saving of more than 8 kg of sugar per tube of product. In this case, the content of vitamin C in the finished product is more than two times higher than in the case of using the traditional method of blanching in hot water. Studies on the heating and actual lethality of microorganisms have shown that the developed mode provides the industrial sterility of canned food, saves heat energy, and shortens the duration of the heat sterilization mode by 20 min.
