Description

Technical Field

[0001] The invention relates to the technical field of food processing, and more specifically to a preparation process of a soft pear juice beverage. Background Art

[0002] Soft pear, also known as frozen pear and perfume pear, is a special fruit grown in the northwest region, mostly in Qinghai and Gansu. The fruit has a unique flavor and rich nutrition, and is deeply loved by local consumers. At present, the planting area and output of soft pears on the market are expanding year by year and have begun to take shape. However, for many years, soft pears have been mainly eaten fresh. Due to many factors such as season, preservation, transportation, and storage, the commodity conversion rate of soft pears is low. The difficulty in selling fruits and the low commodity added value have seriously dampened the production enthusiasm of fruit farmers, and at the same time restricted the sustainable development of soft pear planting industry. Deep processing of soft pears is imperative. At the same time, the processing and utilization of soft pears are mainly concentrated on traditional pear paste, pear wine and other products, and the development of soft pear juice beverages is still relatively limited. Therefore, it is of great practical significance to develop a soft pear juice beverage with good taste and rich nutrition. Summary of the invention

[0003] In view of this, the present invention provides a preparation process of a soft pear juice beverage with good taste and rich nutrition.

[0004] To achieve the above purpose, the present invention provides the following technical solution, which is composed of the following components: soft pear juice: 50-60%, sweetener: 1-2%, acidulant: 0.5-1%, stabilizer: 0.1-0.5%, and pure water: the balance.

[0005] Preferably, in the preparation process of the above-mentioned soft pear juice beverage, the preparation process comprises the following steps:

[0006] Step 1: Pretreatment of soft pears

[0007] Select ripe, disease-free and insect-free pears, wash them, peel them, remove the core, and cut them into small pieces;

[0008] Step 2: Juice

[0009] Put small pieces of soft pear into a juicer to extract juice, and obtain soft pear juice;

[0010] Step 3: Filter

[0011] The raw soft pear juice is filtered through a filtering device to remove impurities and pomace therein to obtain clarified soft pear juice;

[0012] Step 4: Provisioning

[0013] According to the formula ratio, add soft pear juice, sweetener, acidulant, stabilizer and purified water into the mixing tank and stir thoroughly;

[0014] Step 5: Homogenize

[0015] The prepared soft pear juice beverage is homogenized to make various ingredients evenly distributed, thereby improving the stability and taste of the product;

[0016] Step 6: Sterilization

[0017] The homogenized soft pear juice beverage is sterilized to kill the microorganisms therein and ensure the safety of the product;

[0018] Step 7: Filling

[0019] The sterilized soft pear juice beverage is bottled to obtain a finished product.

[0020] Preferably, in the preparation process of the above-mentioned soft pear juice beverage, the sterilization method can be one or a combination of high-temperature instantaneous sterilization and pasteurization.

[0021] It can be seen from the above technical solution that, compared with the prior art, the present invention discloses a preparation process for a soft pear juice beverage, which has the following advantages:

[0022] 1. The soft pear juice beverage of the present invention has a simple preparation process, is easy to operate, and is suitable for large-scale production.
