FIELD: food industry.SUBSTANCE: invention is related to preservation industry. The pear and quince compote production method is as follows: after preliminary preparation and packing into jars, fruits are poured with 85°C hot water for 3 minutes; then water is replaced with 98°C syrup. Then the jars are sealed, put into carrier ensuring ait-tightness; compote is heated in 120°C heated air flow at a rate of 1.5 m/sec during 50 minutes. Then one performs maintenance in a chamber at a temperature of 105°C during 15 minutes and cooled in 20-22°C air flow at a rate of 7-8 m/sec during 25 minutes. During the process of heat treatment in an air flow, heated up to 120°C, and cooling the jar is subjected to interrupted 2-3-minutes' turning upside down with a frequency equal to 0.3 secwith a 2-3 minutes' interval.EFFECT: invention ensures the process duration reduction, the ready products quality improvement and significant saving of thermal energy and water. |
