摘要

采用蒸汽、水和微波两种不同的系统对绿芦笋进行短时间和长时间的焯水，并在不同的条件下采用鼓风和液氮进行冷冻。考察了工艺条件对剪切力值(韧性)、维生素C、膳食纤维、叶绿素和滴漏损失的影响。微波焯水得到的矛具有相近或更高的剪切力值，但维生素C含量较低。低温和鼓风冷冻在剪切力值、维生素C、叶绿素和膳食纤维方面无显著差异，而低温冷冻显著降低了滴漏损失。剪切力值增加，维生素C略有下降，而膳食纤维和叶绿素在冷冻贮藏期间没有变化。

Changes in Texture and Nutritional Quality of Green Asparagus Spears (Asparagus officinalis L.) during Microwave Blanching and Cryogenic Freezing

Green asparagus spears were blanched for a short or long period by steam, water or microwave in two different systems, and spears were frozen by blast or liquid nitrogen under different conditions. The influence of the process conditions on shear force values (toughness), vitamin C, dietary fibre, chlorophyll and drip loss was investigated. Spears with similar or higher shear force values and lower vitamin C were obtained by microwave blanching than by steam and water. No differences were found in shear force values, vitamin C, chlorophyll and dietary fibre between cryogenic and blast freezing, whereas cryogenic freezing reduced the drip loss significantly. Shear force values increased and vitamin C decreased slightly, whereas dietary fibre and chlorophyll did not change during frozen storage.
