研究了綠蘆筍經(jīng)冰溫貯藏后不同出庫方式對其品質(zhì)的影響。實驗以冠軍品種綠蘆筍為試材,經(jīng)冰溫貯藏(-0.2~-0.5℃)15d后,采用四種升溫方式,研究不同出庫方式對冰溫貯藏后的綠蘆筍品質(zhì)的影響。結(jié)果表明:緩慢升溫的出庫方式可以有效地延長綠蘆筍的貨架期,其中G-2處理效果最為明顯。方式G-2可使綠蘆筍保持較好的感官品質(zhì)、可溶性固形物含量和硬度,并有效地降低了綠蘆筍呼吸強度、電導(dǎo)率和MDA含量,但G-2對綠蘆筍VC含量和PAL活性的影響不大。

The effect of different out-store tests after ice-temperature p reservation on Green Asparagus quality was investigated.The experiment selec ted Cham p ion as experimental material.Through ice-tem perature p reserving(-0.2~-0.5℃)15d,using four kinds ofwarm ing slow methods,the effect of d ifferent out-store tests after ice-temperature p reservation on Green Asparagus quality was investigated.The result showed that:Shelf-life of Green Asparagus could be extended effectively by gradually warm ing,and G-2 was the most obvious.Better sensory quality,solub le solid content and firmness of Green Asparagus could be kep t by G-2. And the conductivity and MDA content of Green Asparagus could be reduced effectively.But the VCcontent,PAL activity couldn’t be effectively affected by G-2.
蘆筍(Asparagus officinalis L.)又名石刁柏、龍須菜等,屬百合科(Liliaceae)天門冬屬(Asparagus)中的食用品種[1]。目前,我國蘆筍的種植面積居世界前列[2]。蘆筍以嫩莖為食,不僅色澤鮮綠,脆嫩爽口,而且富含多種營養(yǎng)與保健成分,深受消費者的喜愛[3]。但是,采收后的綠蘆筍因呼吸與蒸騰作用旺盛,生理代謝活躍,而且嫩莖組織易受病菌侵染,所以極不耐貯藏[4]。冰溫保鮮技術(shù)較其他保鮮方法能更好的保持果蔬的品質(zhì),近年來備受研究人員關(guān)注,該技術(shù)在草莓、荔枝及獼猴桃等的貯藏方面已有研究,取得了較好的效果[5-8]。……
