沼气保鲜柑桔技术研究课题,于1987年4月21日在开县通过了部级技术鉴定。认为:立题新颖,装置设计简单,工艺合理,试验结果达到了计划指标,即贮藏150天,好果率达90%以上,失重率小于5～7%。使用该项技术保鲜的甜橙,果实饱满新鲜(青蒂率达95.47%),果肉多汁,甜酸适度(可溶性固形物9～10%),保持了鲜果的风味,无枯水、异臭、异味。每0.5千克(公斤)甜橙的贮藏费用为5分钱,无污染。有利于果农分散贮藏。该项技术属国内首创。 Biogas fresh citrus technology research project, in April 21, 1987 in Kaixian passed ministerial technical appraisal. The results show that the novel design has the advantages of simple device design and reasonable process, and the test result has reached the planned index. That is to say, after 150 days of storage, the good fruit rate is over 90% and the weight loss rate is less than 5 to 7%. The fresh orange with this technology is full of fresh fruits (Qingti rate of 95.47%), juicy flesh and moderate sweetness and acidity (soluble solids of 9 ~ 10%), maintaining the flavor of fresh fruits, without dry water, , Smell. Every 0.5 kg (kg) of orange storage costs 5 cents, no pollution. Conducive to farmers scattered storage. The technology is a national initiative.
