대추의 소개
잘 알려진 전통 건강식으로 대추에는 다양한 영양소가 풍부합니다. 대부분 건조되어 소비자에게 건조하고 세척된 과일로 바로 섭취됩니다. 또한 대추 재배 지역은 비교적 집중되어 있으며 대부분의 신선한 대추는 가을에 거의 동시에 수확되어 전체 시장에 공급됩니다.
대추를 어떻게 건조하나요?
대추 가공의 핵심은 건조입니다. 건조 과정은 원래의 품질을 최대한 유지하는 전제하에 수분의 증발과 당의 전환으로 구성됩니다. 저장, 운송, 판매를 위해 생 대추는 세척, 건조, 냉각, 연화, 살균, 포장이 필요합니다.
Red dates abound in sugars. Among them, the polysaccharide is not sweet and only becomes sweet after inverted into simple sugars by the function of the biological enzymes. It is the reason why cured jujube is sweet. If we want to invert sugars fully, we need to strengthen the activity of the biological enzymes. After a long time of practice in our 건조 오븐, we have found the most suitable temperature for completely sugar conversion is about 60°C.
대추의 건조 과정
대추를 건조하는 과정에서 명확히 해야 할 많은 세부 사항이 있습니다. 일반적으로 건조 과정은 예열, 증발, 건조, 냉각의 네 단계로 나뉩니다. 아래는 건조 과정 중 주의 사항 및 과정 소개입니다.
Preheating: If we directly put red dates in the environment where the temperature is suitable for sugar conversion, the extreme temperature difference will make red dates set off the protective reaction. The cell orifice in the skin will shrink and the crust will become hard to prevent water from evaporating. Therefore, sufficient preheating is required in the early drying to prepare for the evaporation. First, the red dates need to be dried at 35°C for 6-10 hours. When the temperature of red dates reaches 45°C, your finger will feel hot when touching it. After drying them for 7-8 hours, use your finger to press the red date and wrinkles will appear on the surface. When the temperature is at 45°C-48°C, there will be some small water drops on their skin.
Evaporation: Raise the temperature to 65°C (Note: the temperature shall not be higher than 70°C) within 8-12 hours to evaporate most of the free water. Keep the indoor temperature stable for constant evaporation. The drying process goes well when the wrinkles appear on the surface.
Drying up: When the temperature in the red date is uniform, this step will end within 6 hours. In this phase, the moisture content of red dates is not high, and thus more attention shall be paid to temperature control. It is best to keep the temperature at 50°C. At this moment, relative humanity has been declined. As the water in the red dates is gradually balanced, the drying process is completed. Note that the dried red dates shall be taken out in time.
Cooling: Keep good ventilation and heat dissipation for dried red dates. Pile them up until being cooled. If the dried red dates are just taken out from the cabinet, and directly piled up in the warehouse, their sugars will ferment and go bad, and the pectose will be broken down into pectin and pectic acid due to high heat. Therefore, it is necessary to wait for the completely cold zone before piling up.
