营养方便食品食用菌的开发

文档编号:SP106  文档字数:10304,页数:19

摘  要：食用菌含有丰富的蛋白质和人体必需的多种氨基酸, 营养价值很高。食用菌还具有特殊营养保健功能和药用价值。目前我国食用菌的主要加工方式还是以简单的加工（罐头、蜜饯、腌制品、糖制品）为主，深加工还处于起步阶段。而近年来，人们对食用菌消费也提出了新的要求, 营养、新鲜、方便、保健成为新的消费时尚；我国又是食用菌生产大国，产量居世界第一，因此开展食用菌的深加工（冻干产品）非常有意义。
 本文档旨在以先进的真空渗透、冷冻干燥工艺取代原有的烘干、腌制， 用工业化手段生产高附加值的食用菌产品，既产生了经济效益，同时也加速了传统农业的高科技改造。
关键词：食用菌 真空渗透 冷冻干燥

Abstract: Edible Funguses contains rich proteide and various essential amino acid, nutrient value was high. Edible funguses has the particular nutrition health function and medical value. At present, the main part processing way of the edible fungus of our country was simple process(can, candy, salted products,sugar products),deep processing is in starting phase. However, people also put forward the new consumptive request to edible funguses in recent years, nutrition、fresh、convenient、health care become a new consumption style; Our country is that edible funguses produces Great Power, output occupies the first place in the world, so develop the deep processing (freeze-drying product) of edible funguses has meaning very much.
 This paper aim at using the advanced processing technology vacuum penetration, freeze-drying to replace the old technology drying and salted , producting that have high additional value product, not only produced an economic benefit , also having accelerated the reforms of tradition agriculture at the same time.
Keywords: Edible Fungi; vacuuming penetration; freeze-drying
