木耳是我國普遍的食用菌之一。目前在市面上有五種木耳,包括黑耳(
Auricularia mesenterica(Dickson)Persoon)、紅耳(Auricularia
polytricha(Montagne)Saccardo)、斤耳(Auricularia
fuscosuccinea(Montagne)Farlow, brown strain)、雪耳(
Auricularia fuscosuccinea(Montagne)Farlow, white strain)及白
木耳(Tremella fuciformis Berkeley)。雪耳為斤耳之白色變種,是一
種新興的菇類。木耳通常被認為沒有菇類特殊的香味,目前並未有學者研
究不同木耳間之品質,以提供營養價值及風味作為其它研究之參考。菇類
在受到傷害時,會因酵素之作 在木耳品質評估方面,由一般成分
分析可知,雪耳之粗脂質、粗纖維及蛋白質高於白木耳,且碳水化合物之
白木耳低,而相較於黑耳、紅耳及斤耳亦有此優點。可溶性糖類分析中,
五種木耳之可溶性糖均很少,而白木耳含卻有高量之還原糖,顯示其具有
較高之熱量。從總胺基酸分析得知,五種木耳均含有九種必需胺基酸。由
游離胺基酸分析得知,五種木耳的游離胺基酸含量很低,對呈味較無貢獻
。在核酸分析中,以雪耳之呈味核酸含量最高。有機酸分析中,五種
木耳主要含有乳酸,缺乏具鮮味之琥珀酸。由脂肪酸之分析可知五種木耳
含豐富的不飽和脂肪酸,並均 在木耳菌絲線性生長速率上,ODA
對黑耳、紅耳、斤耳和雪耳菌絲皆有促進之作用。10 ppm之ODA添加量,
可使紅耳、斤耳及雪耳之相對線性生長速率分別為1.167、1.451及2.013
。ODA亦會促進黑耳菌絲生長,但在不同濃度之ODA下並不顯著。
在紅耳菌絲液態培養時,ODA濃度愈高,則採收之菌絲體乾重及漆活性
愈高。添加10 ppm ODA可提高紅耳菌絲乾重至控制組之118%,而漆活性
則提高至控制組之250 %。 在雪耳太空包栽培方面,ODA添加劑量
愈高,第一、第二週期及其兩者之總和之雪耳產量愈高。而使用柳松菇熱
水萃取液只有增加第一週期雪耳產量之效果。在菇農應用於雪耳太空包栽
培之使用上,建議ODA使用劑量在5 ppm以上為佳。本研究經由評估五種木
耳之品質得知,五種木耳之呈味品質較其他菇類為低,但胺基酸及脂肪酸
之組成優良,可作為健康食品之一。在菇類生理活性物質ODA方面,ODA對
木耳菌絲生長有促進之效果。在實際菇類栽培上,ODA亦能縮短雪耳菌絲
在太空包中的生長時間,提高雪耳之產量。由本實驗之結果,可進一步將
之應用於其他菇類栽培上,以期縮短栽培期及增加其產量。
Ear mushrooms are popular in Taiwan. Five kinds of ear
mushroom are commercially available in Taiwan, including black
(Auricularia mesenterica (Dickson) Persoon), red (Auricularia
polytricha (Montagne) Saccardo), jin (Auricularia fuscosuccinea
(MontagneFarlow), brown strain), snow (Auricularia fuscosuccinea
(Montagne) Farlow, white strain) and silver ears (Tremella
fuciformis Berkeley). Snow ear is a translucent white of jin
ears, which is a newly cultivated edible ear mushroom in Taiwan.
For most p The snow ear contained higher crude fat,
fiber and protein and lower carbohydrate than silver ear. The
same advantage made it possible to compete with other ears.
These ear mushrooms contained very low amount of soluble sugars.
The silver ear contained high amount of reducing sugars, which
meant that it contained high calories. These five ears contained
nine kinds of essential amino acid but very low amount of free
amino acids. The snow ear contained highest amount of flavor
5''-nucleotides. The mai On the linear growth rate, ODA
had a significant effect on the mycelial growth of black, red,
jin, and snow ear. The relative linear growth rate of red, jin,
and snow ears were 1.167, 1.451 and 2.013 at the concentration
of 10 ppm ODA, respectively. ODA could raise the growth rate of
black ear, but had no significant effect at any concentrations
of ODA. In liquid culture of red ear, it was found that
the higher concentrations of ODA, the higher concentrations of
biomass and laccase activity. At 10 ppm ODA, the biomass and
laccase activity of mycelium of red ear were about 118%, and 250
% of mycelial growth compared to that of the control,
respectively. In the log cultivation of snow ear, it was
found that the higher concentrations of ODA, the higher yield of
snow ear at the first, second flush and the sum of the first and
second flush. For the application of ODA on snow ear
cultivation, the use of more than 5 ppm ODA was suggested.
The flavor qualities of ear mushroom were lower than other
mushrooms. Due to the compositions of amino acid and fatty acid.
Ear mushrooms could be the healthy food. The mushroom
biologically active substance-ODA could promote the growth of
ear mushroom mycelium. In the application of mushroom
cultivation, ODA could promote the growth of mycelium and
increase the yield of snow ears. The result of the present study
could be applied to other mushrooms.
