Problems solved by technology

[0004] Hawthorn can be eaten fresh, but its acid content is high, so it is not suitable to eat more. At present, the processed hawthorn products mainly include canned hawthorn, hawthorn jelly, hawthorn slices, etc. The processed products are in a single form, and the processing method is mainly heat processing. In the process, the nutrients and active ingredients of raw materials are easily lost, which will significantly reduce their nutrition, drug efficacy and active ingredients.

Embodiment 1

[0023] Take fresh hawthorn (the variety is Xinglong) as the raw material, and measure the various indicators of the fresh hawthorn raw material according to the following methods:

[0024] Moisture determination method: drying method. Specifically: accurately weigh 2-10g of the sample, place it in a covered weighing bottle that has been dried, cooled and weighed to constant weight, move it into a normal pressure oven at 95-105°C, open the cover and bake for 2-4 hours, then take it out. Covered and placed in a desiccator to cool for 0.5h and then weighed. Weigh after baking for another hour. Repeat this operation until the mass difference between the two times before and after does not exceed 2mg, which is the constant weight after drying, and the water content = (fresh weight (weight before drying) - constant weight after drying) / fresh weight.

[0025] Determination method of total sugar: determine the total sugar content according to the national standard GB6194-86 Determin...

Abstract

The invention discloses an ultrafine whole haw nutrient powder and a preparation method thereof. The method includes the following steps: haw material is sequentially prerefrigerated, dried by sublimation, dried by desorption and ground to be ultrafine, so that the ultrafine whole haw nutrient powder is prepared. The ultrafine whole haw nutrient powder provided by the invention has unique physical and chemical properties and good fluidity, anticaking property and dispersibility, and keeps the nutritional ingredients of the haw material, and moreover, the ultrafine powder form is good for the ultrafine whole haw nutrient powder to be blended with other food materials, and plays an extremely important role in increasing the digestibility, absorbability and bioavailability of the nutritional substances of the haw. The ultrafine whole haw nutrient powder can be used as main material for the preparation of healthy haw beverages, soft sweets, fruit juice and the like as well as material for the production of novel functional food, and can be stored for a long time.

Description

technical field [0001] The invention belongs to the field of food processing, and relates to a hawthorn ultramicro nutritional whole powder and a preparation method thereof. Background technique [0002] Hawthorn (Cretaceus pinnatifida Bag) is a plant of the genus Rosaceae Crataegus in the family Rosaceae. It is a specialty fruit tree that originated in my country and has a cultivation history of more than 3,000 years. "Flora of China" records 18 species, 6 varieties, and 1 variety.
