Processing method of honey dried sweet potato

Abstract

The invention discloses a method for processing honey dried sweet potatoes, which comprises the following steps: candying potato strips or blocks which are pretreated by boiling and steaming, and performing the treatments of decompression package, pasteurization and quick cooling. The dried sweet potatoes prepared by the processing method have good mouthfeel, and the guarantee period thereof can be more than 270 days at normal temperature.

Description

technical field [0001] The invention belongs to the field of deep processing of agricultural products, and in particular relates to a quality-preserving and fresh-keeping processing method of dried sweet potatoes with honey. Background technique [0002] Sweet potato has many aliases in my country, such as sweet potato, sweet potato, sweet potato, sweet potato, etc. Its scientific name is sweet potato (ipomoeabatatas lam.), and it has been introduced to my country for more than 400 years. It has high yield, wide use and strong adaptability. An important food crop, the planting area ranks first in the world. In recent years, with the continuous development of my country's agricultural production, changes in people's food composition, and the rise of food and feed processing industries, the status of sweet potatoes in food has changed, from the original coarse grains to industrial raw materials and excellent feed crop. [0003] Sweet potato contains a variety of nutrients, suc...

Problems solved by technology

However, due to the high water content of sweet potatoes, the storage of fresh sweet potatoes has strict requirements on environmental conditions and storage technology. The medium shelf life does not exceed three days (72 hours), and the mechanical damage to the sweet potato skin in the process of harvesting, storage, transportation, and sales can easily lead to rot. Therefore, sweet potato foods often need to be processed to extend the shelf life.

[0006] At present, there are many sweet potato processed products on the market, such as roasted sweet potato, preserved sweet potato, sweet potato strips, roasted sweet potato slices, fried sweet potato slices, etc., but most of these products have complex processing techniques, such as preserved sweet potato and sweet potato strips, which need to be hardened and sugaring treatment, baked sweet potatoes are difficult to maintain due to the high water content of the product, while roasted sweet potato slices and fried sweet potato slices have complex forming processes, sweet potato flavors change more, and production equipment investment is relatively large. Therefore, a production investment is invented. The sweet potato processing technology with less and simple processing technology makes the sweet potato have a unique flavor on the basis of better maintaining the original nutritional content. At the same time, it is convenient to eat, hygienic and has a long shelf life. This is an urgent technical problem to be solved.
