Description

南果梨果醋酿造工艺 Brewing Technology of Nanguo Pear Fruit Vinegar

一、技术领域 1. Technical field

本发明涉及一种南果梨果醋酿造工艺,专用于南果梨果实,进行南果梨果醋酿造。The invention relates to a brewing process of Nanguo pear fruit vinegar, which is specially used for brewing Nanguo pear fruit vinegar.

二、背景技术 2. Background technology

南果梨为辽宁省特色梨果。其果实色泽鲜艳,果肉细腻,爽口多汁,果味香浓而弛名于国内外。其“优质南果梨产业化发展和南果梨高产高效栽培模式”推广项目,已列入2004年国家星火计划。辽宁省南果梨栽培面积80万亩,年产量30万吨,年产值1.5亿元以上,年出口创外汇达0.3亿元。但优质南果梨少,尤其红果率低,经过30余年的科学研究,红果率仅为40%左右,远远低于其它着色果实的红果率,特别是在成熟期雨后退色率为100%,再着色缓慢,产生大量劣等果实。采收时劣等果0.4-0.8元/kg,优等果10-12元/kg,春节期间高达20元/kg。另外南果梨是一种非常不耐贮存的水果,常温下经过十几天后熟过程以后,两三天内就快速腐烂。对着色不佳的劣等果实及不宜再储藏的南果梨果实进行深加工,生产南果梨果醋,是提高南果梨经济效益及实现南果梨产业化的一个重要途径。Nanguo pear is a special pear fruit in Liaoning Province. Its fruit is bright in color, delicate in flesh, refreshing and juicy, and has a strong fruity flavor, which is well-known at home and abroad. Its promotion project of "industrial development of high-quality Nanguo pear and high-yield and high-efficiency cultivation model of Nanguo pear" has been included in the 2004 National Spark Plan. The cultivation area of Nanguo pear in Liaoning Province is 800,000 mu, with an annual output of 300,000 tons, an annual output value of more than 150 million yuan, and an annual export revenue of 30 million yuan. However, there are few high-quality Nanguo pears, especially the red fruit rate is low. After more than 30 years of scientific research, the red fruit rate is only about 40%, which is far lower than the red fruit rate of other colored fruits, especially the fading rate of 100% after rain in the ripening period. Recoloration is slow, producing large quantities of inferior fruit. When harvesting, inferior fruit is 0.4-0.8 yuan/kg, high-quality fruit is 10-12 yuan/kg, and it is as high as 20 yuan/kg during the Spring Festival. In addition, Nanguo pear is a kind of fruit that is not resistant to storage. After more than ten days of post-ripening at room temperature, it will quickly rot within two or three days. It is an important way to improve the economic benefits of Nanguo pear and realize the industrialization of Nanguo pear by further processing the inferior fruit with poor coloring and the Nanguo pear fruit that is not suitable for further storage to produce Nanguo pear vinegar.
