摘要
绿色储粮技术的创新发展是粮食储藏领域的重要研究课题,气调储粮是绿色储粮技术之一。开展了气调剂在第五储粮生态区域(中温高湿环境)对优质籼米保质保鲜储藏的实验研究,实时监测储藏环境氧气浓度、温度和相对湿度,并对保质保鲜效果进行评价。结果表明:新型气调剂气调技术可有效保持第五生态区域所储优质籼米的品质,并可适当延长保质储藏时间。与对照组相比,气调剂实验组在5个月储藏期间,密闭储藏空间内氧气浓度维持在0.1%以下,相对湿度维持在70%;气调剂实验组优质籼米的水分含量比对照组高0.98%,脂肪酸值比对照组低1.34 mg (KOH)/100 g,新鲜度比对照组高7分。由此可知,气调剂气调技术可以按照需求调控密闭空间内氧气浓度和相对湿度,实现保质保鲜储粮目的,是一种绿色低碳保质的储粮新技术。
The innovative development of green technology is the permanent scientific research topic in the field of grain storage, and the controlled atmosphere is one of the green grain storage technologies.This paper carried out the research on the storage technology of high-quality indica rice in the fifth ecological area of grain storage(medium temperature and high humidity) by air-regulating agent. The concentration of oxygen, temperature and relative humidity of the storage environment were monitored, and the quality of high-quality indica rice was also evaluated. The results showed that the technology of air-regulating could effectively delay the quality deterioration of rice. Compared with the controlled group, the experiment group can maintain the concentration of oxygen in the confined space below 0.1% and the relative humidity at 70% during the 5-month storage period. The moisture content of the controlled atmosphere group was 0.98% higher than that of the controlled group. The fatty acid value was 1.34 mg(KOH)/100 g lower than that of the controlled group, while the freshness was 7 points higher than that of the controlled group. The above results showed that the air-regulating agent can adjust and control the oxygen concentration and relative humidity in the confined space according to the demand, which could achieve the purpose of preserving the quality and freshness of grain. It is a green, low-carbon and fresh-reserving new grain storage technology.
