Description

An pear dietary fiber beverage and preparation method thereof

technical field

The invention relates to beverage processing, and more specifically relates to an pear dietary fiber beverage and a preparation method thereof.

Background technique

An pear, also known as sour pear, is one of the representative varieties of Qiuzi pear system, with a cultivation history of more than 500 years. It is cultivated in the northeast of Hebei, Liaoning, Jilin and other places. The growth characteristics of its varieties are extremely adaptable, strong cold resistance, and can withstand low temperatures of -50°C. It is the most cold-resistant variety in the genus Pyrus. Hebei Anli accounts for 35-45% of the total number of cultivated plants in the country, with a planting area of 11,487.1 hectares (hm2), and an output of about 13,000 tons. The total planting area ranks fourth, and the total output ranks eighth.

Anli is rich in nutrition, with a soluble solid content of about 8%, a titratable acid of about 0.4%, a sugar-acid ratio of about 20:1, and a variety of minerals. The content of acid and Vc in the fruit ranks first among all kinds of pears, and it has the effects of eliminating phlegm and relieving cough, lowering blood pressure, promoting body fluid and quenching thirst, nourishing the spleen and stopping diarrhea, harmonizing the stomach and reducing adverse reactions, clearing the heart and moistening the lungs.

Although there are more than a dozen kinds of Anli processed products at present, the waste utilization rate after Anli processing is low, and most of them are used as livestock feed or directly discarded, such as: Chinese patent CN200810172190.X discloses an Anli juice drink, which adopts The conventional blending method is to mix Anli juice, water, sugar and food additives such as cyclamate. Although the preparation method is simple, the waste after Anli processing has not been treated. Anli pomace itself contains a large amount of dietary fiber, which can be added to food as a functional food raw material to improve the nutritional content of food and improve sensory properties. Therefore, increasing the utilization of Anli pomace and increasing the added value of products can promote Anli pomace healthy development of the industry.

Therefore, it is an urgent problem for those skilled in the art to provide an Anli dietary fiber beverage with simple process and high nutritional value and a preparation method thereof.

Contents of the invention

In view of this, the invention provides a pear dietary fiber drink.

In order to achieve the above object, the present invention adopts the following technical solutions:

An pear dietary fiber beverage is characterized in that it comprises the following components by mass percentage: 30-35% of pear juice, 3-5% of pear dregs powder, 8-10% of white sugar, 0.05-0.08% of sodium iso-Vc, Citric acid 0.25-0.30%, CMC 0.12-0.18%, xanthan gum 0.08-0.12%, potassium sorbate 0.03-0.08%, and the rest is supplemented with pure water.

By adopting above-mentioned formula, the beneficial effect of the present invention is:

In the present invention, Anli dietary fiber beverage has adopted Anli juice, Anli dregs, white granulated sugar, sodium iso-Vc, citric acid, CMC, xanthan gum, potassium sorbate, by adopting the above-mentioned raw materials, its effect is as follows:

Main materials used in the present invention are pear juice and pear dregs.

Anli is rich in nutrition, with a soluble solid content of about 8%, a titratable acid of about 0.4%, a sugar-acid ratio of about 20:1, and a variety of minerals. The content of acid and Vc in the fruit ranks first among all kinds of pears, and it has the effects of eliminating phlegm and relieving cough, lowering blood pressure, promoting body fluid and quenching thirst, nourishing the spleen and stopping diarrhea, harmonizing the stomach and reducing adverse reactions, clearing the heart and moistening the lungs.

Sodium isoVC is an important anti-oxidant preservative in the food industry. It can maintain the color and natural flavor of food, prolong the shelf life, prevent the formation of carcinogens in pickled products - nitrosamines, and eradicate the discoloration, odor and Cloudy and other adverse phenomena, and without any side effects.

CMC: sodium carboxymethyl cellulose, also known as sodium carboxymethyl cellulose, carboxymethyl cellulose, is a fiber derivative obtained by chemically modifying natural cellulose. CMC has excellent properties such as thickening, dispersion, suspension, adhesion, film formation, protective colloid and moisture protection, and is used as a thickener in food.

Xanthan Gum: Xanthan Gum is an extracellular microbial multipond produced by the fermentation of sugars by Xanthomonas bacteria. It can be used as emulsifier, stabilizer, gel thickener, wetting agent, film forming agent, etc. Xanthan gum in food: Xanthan gum can thicken dairy products and salads, and maintain the consistency and fluidity of food appearance. It is also used to keep ice cream from crystallizing and to make low-fat and fat-free dairy products more filling.

The formula of the present invention also further discloses the proportional relationship of each material, and by adopting the above-mentioned ratio, the beneficial effects of the present invention are as follows:

The dietary fiber content of Anli pomace powder is as high as about 80%. Adding 3-5% of Anli pomace powder makes the Anli beverage of this formula not only have the characteristics and flavor of traditional Anli beverage, but also contain 2.4-4.0% of high-quality dietary fiber. The dietary fiber requirement of a person is 30-40g per day, and drinking 0.5-1L of this beverage can almost meet the daily dietary fiber requirement.

Another object of the present invention is to provide a method for preparing an pear dietary fiber drink.
