Problems solved by technology

[0004] The existing technical literature discloses a variety of pear paste products and their preparation methods, but in the process of processing, no appropriate extraction and preparation process measures have been taken for the characteristics of the arbutin contained, thus affecting the product quality and health care effect
In addition, non-food ingredients such as other traditional Chinese medicines are usually used in the formulas disclosed in the existing patented technology for making pear paste, which will first of all make the food safety and commodity attributes of the product questionable (whether it is a drug or a food). There are also issues with palatability and acceptability for consumption

preparation example Construction

[0011] The invention provides a kind of cough-relieving pear paste specially for children and its preparation method, comprising the following steps:

[0012] (a) First wash the pears, peel and remove the pits, squeeze and filter the pear pulp to obtain pear juice and pear residue; then beat the pear skin, pear core and pear residue, and extract with water to obtain extracted pears juice, (b) vacuum-concentrate squeezed pear juice and extracted pear juice to obtain concentrated pear juice, (c) use high-performance liquid chromatography to detect the content of arbutin in the two pear juices, and carry out according to product requirements Mixing, finally adding carrageenan, heating and mixing to make pear paste.

[0013] The present invention is not strictly limited to the species and varieties of the pears, including white pears, sand pears, Qiuzi pears, Xinjiang pears, and Western pears, and the preferred species are white pears and sand pears. Preferred varieties include: ...

Embodiment 1

[0026] 300kg of duck pears are cleaned, peeled, and cored to obtain pear pulp, which is cut into pieces, placed in a juicer to squeeze the juice, and filtered with a bag centrifuge to obtain the filtrate; the filtrate is adopted by a vacuum thin film evaporator ( flash evaporation) to concentrate, the feed temperature of the pear juice is 80°C, the temperature of the evaporator is 110°C, the concentration time is less than 0.1min, and the temperature of the concentrated pear juice is 70°C. Make pulp concentrated pear juice 50kg, its soluble solids content is 50 ° of Brix. Use high performance liquid chromatography (HPLC) to measure the content of arbutin in pear juice according to the above-mentioned analytical conditions, wherein the content of arbutin is 400mg / kg, figure 2 It is the HPLC figure of arbutin in the concentrated pear juice that prepares. Then crush the collected pear skin, pear core, and pear dregs, add 3 times hot water for extraction, the temperature is 60°C...

Embodiment 2

[0028] Wash, peel and core 300kg of Chili pears to obtain pear pulp, cut the pear pulp into pieces, squeeze the juice in a juice extractor, and filter with a bag centrifuge to obtain the filtrate; filter the filtrate with a double-effect vacuum membrane The evaporator is concentrated, the first-effect heating temperature is 83-85°C, the second-effect heating temperature is 70-72°C, and the feed temperature of pear juice is 80°C. Prepare 50kg of concentrated juice with a concentration of 50-52°Brix. The content of arbutin in the pear juice was determined according to the above analysis conditions by high performance liquid chromatography, wherein the content of arbutin was 350mg / kg. Crush the collected pear skin, pear core, and pear dregs, add 2 times hot water to extract, the temperature is 70°C, the extraction time is 15min, centrifugal filtration, and the filtrate is vacuum concentrated in the same way to obtain a concentration of 52°Brix Concentrated juice 10kg, the conten...

Abstract

The invention provides a preparation method of pear syrup special for relieving a cough for children. The preparation method comprises the following steps of cleaning pears, performing peeling, removing pear cores to obtain pear flesh, squeezing the pear flesh to obtain juice, and performing filtering to obtain filter residues and filtrate; and performing extracting on the peel and residues, separately performing vacuum concentration to obtain concentrated pear juice, adding carrageenin, and performing mixing so as to obtain the pear syrup. According to the preparation method disclosed by theinvention, parts high in arbutin content, in pears, are selected as raw materials, and a vacuum concentration method is adopted for preventing long-time high-temperature heating, so that preservationthe arbutin content is facilitated; and a reliable analysis and detection means is used as the auxiliary manner, so that the quality and the health-care effect of products can be guaranteed. In addition, the pear syrup special for relieving a cough for children, provided by the invention, well preserves the fragrance of pears, is moderate in sour and sweet degrees, is suitable for taste of children, and is free from any traditional Chinese medicine components and safe and non-toxic.

Description

technical field [0001] The invention relates to the field of health food, in particular to a cough-relieving pear paste for children and a preparation method thereof. Background technique [0002] Pear is a fruit with a long history of medicine and food in my country. Its medicinal use was first seen in Tao Hongjing’s "Famous Doctors" in the Xiaoliang period.
