摘要

眉茶是我国出口绿茶的主要茶类之一,以条索纤细似眉而得名。眉茶精制过程中产生了大量无法拼配利用的副产物（以茶梗为主）,如何合理利用这些副产物是提高眉茶生产附加值的关键问题之一。以皖南主要栽培黑木耳品种黑3为材料,利用菌丝生长速率、生物利用率、平均产量以及营养成分等评价指标,开展眉茶加工副产物部分取代木屑栽培黑木耳的研究。结果表明,眉茶加工副产物含量为40%的培养基质中黑木耳产量与对照相当,为每棒59.57 g;而其蛋白质、多糖及黄酮含量均高于对照,分别提高了6.29%、12.95%和74.17%,确定眉茶副产物含量为40%的培养基质为栽培黑木耳的最佳培养基质。本研究为眉茶加工副产物的综合利用提供了一条可行的、高附加值的途径。

Abstract

Mee tea is the main export green tea in China, named after the eyebrow-like shape. The produce of Mee tea by-product (mainly including tea stalk) during the refining process cannot be avoided. How to make rational use of Mee tea by-product is a key question to improve the added value of Mee tea processing. In this paper, the main cultivated black fungus variety 'Hei 3' in southern Anhui was used as the material, and comprehensive evaluation indicators such as mycelial growth rate, bioavailability, average yield, and nutrient composition were used to study the replacement of sawdust with the by-product of Mee tea as a substrate for the cultivation of black fungus. The results show that the yield of black fungus in the culture medium containing 40% tea stalk was similar to that of the control, which was 59.57 g·stick^-1. While the contents of protein, polysaccharides and flavonoids were higher than those of the control, which increased by 6.29%, 12.95% and 74.17% respectively. The culture substrate with 40% Mee tea by-product was identified as the best culture substrate for the cultivation of black fungus. This study provided a feasible and high value-added way for the comprehensive utilization of Mee tea by-product.
