Licorice root and psidium guajava freeze-dried slice and preparation method thereof

Abstract

The invention discloses a licorice root and psidium guajava freeze-dried slice and a preparation method thereof. Licorice root and psidium guajava flavor liquid is prepared, and in parts by weight, the prepared licorice root and psidium guajava flavor liquid includes 160-200 parts of licorice root concentrated juice, 60-80 parts of galangal powder, 170-200 parts of green plum paste, 2-5 parts of salt, 40-80 parts of trehalose, 1-3 parts of anhydrous citric acid and 500-800 parts of water, wherein the mass ratio of psidium guajava slices to the licorice root and psidium guajava flavor liquid is1:(1.1-1.5); by optimizing vacuum freeze-drying process parameters, by means of pure natural flavor enhancers, green plums and galangal, on the basis of not adding preservatives, synthetic flavoringagents, coloring agents and food flavors, and the like, the developed waste-free licorice root and psidium guajava freeze-dried slice not only can be used as a good source of VC, but also is significantly increased in content of total phenols and flavonoids; the preparation method for the licorice root and psidium guajava freeze-dried slice not only completely meets the processing concept of greenfoods, but also has important significance in further developing special fruit psidium guajava widely planted in the east Guangdong region, and increasing the added value of agriculture.

Description

technical field

[0001] The invention relates to a preparation technology of a freeze-dried tablet, in particular to a freeze-dried tablet of licorice muzai and a preparation method thereof. Background technique

[0002] Guava (Psidium guajavaL.), also known as guava (chicken fruit, Muzi). The guava peel is thin, the fruit is rich in nutrients, and contains high V A , V C and fiber, as well as trace elements such as phosphorus, potassium, iron, calcium, and magnesium.
