Problems solved by technology

With the acceleration of the pace of life, this kind of folk and low-economic-benefit eating method has gradually been eliminated. At the same time, this naturally frozen product still has safety hazards and cannot form large-scale production. Pear and other autumn pear species were cut down, and the planting area dropped sharply

Embodiment 1

[0019] 1. Select Ruaner pear fruits that are not harmed by diseases and insect pests, clean them to ensure no mechanical damage, and then spray 1600ppm ethephon water solution on the surface of Ruaner pear fruits to accelerate fruit ripening. Send the Ruaner pears after 5 days post-ripening treatment into a cold beater (model is DHLJ03, produced by Xi'an Dinghe Machinery Manufacturing Co., Ltd.), and add 0.2% of the quality of Ruaner pears by dripping. Beat and remove the peel, fruit seeds, fruit stems and rough fibers, then use a heat exchanger to kill the pulp pulp at 85°C for 60 seconds to passivate the discoloration enzyme in the pulp pulp, and then use a 1mm mesh refiner to remove the pulp pulp The black dots and stone cells in the pear are obtained to obtain a soft pear pulp with uniform texture and fineness.

[0020] 2. Mix 1000g Ruaner pear pulp, 30g galacto-oligosaccharide (produced by Quantum Hi-Tech Biological Co., Ltd.), 40g starch, 25g compound glue, 1.5gCaCl 2 M...

Embodiment 2

[0022] 1. Prepare soft pear pulp according to the method of step 1 of embodiment 1.

[0023] 2. Mix 1000g Ruaner pear pulp, 20g galacto-oligosaccharide (produced by Quantum Hi-Tech Biological Co., Ltd.), 30g starch, 20g compound glue, 1.0gCaCl 2 Mixing, wherein the composite gum is compounded by low-methyl pectin, xanthan gum, and carboxymethyl cellulose in a mass ratio of 2:1:1, and is homogenized by a high-pressure homogenizer under a pressure of 30MPa. Then use a heat exchanger to sterilize at 90°C for 30 seconds, and carry out aseptic filling according to 50mL. The filled product is cooled to -0.5°C, and quickly frozen at -30~-35°C until the center temperature of the product reaches below -18°C , save and sell.

Embodiment 3

[0025] 1. Prepare soft pear pulp according to the method of step 1 of embodiment 1.

[0026] 2. Mix 1000g Ruaner pear pulp, 40g galacto-oligosaccharide (produced by Quantum Hi-Tech Biological Co., Ltd.), 40g starch, 30g compound glue, 2.0g CaCl 2 Mixing, wherein the composite gum is compounded by low-methyl pectin, xanthan gum, and carboxymethyl cellulose in a mass ratio of 2:1:1, and is homogenized by a high-pressure homogenizer under a pressure of 30MPa. Then use a heat exchanger to sterilize at 90°C for 30 seconds, and carry out aseptic filling according to 50mL. The filled product is cooled to -0.5°C, and quickly frozen at -30~-35°C until the center temperature of the product reaches below -18°C , save and sell.

Abstract

The present invention discloses a sterile packaged frozen prebiotic Pyrus ussuriensis product and a processing method thereof. The frozen product consists of the following components in parts by mass: 100 parts of Pyrus ussuriensis pulp, 2-6 parts of galacto-oligosaccharides, 3-8 parts of starch, 1.5-4.5 parts of compound gum and 0.07-0.30 part of CaCl2 (subscript). Pyrus ussuriensis fruits are cleaned, subjected to ripening treatment and pulp separation, pasteurized, and performed with pulp refining to prepare the Pyrus ussuriensis pulp. The compound gum is prepared by compounding low methoxyl pectin, xanthan gum and carboxymethyl cellulose. An industrial processing method was conducted on pears in the Pyrus ussuriensis system using modern processing technology, and the obtained product can reach quality and texture of the folk frozen pear product and endows the prebiotics necessary for human body at the same time, and industrialized production can be achieved. The frozen product is easy to preserve and convenient to eat, and an optimum temperature for eating the frozen product is from 0.5 to -4 DEG C. The invention provides technical support and possibility for the industrialized production of folk traditional products, and the change from the regional to the national market.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to an aseptically packaged frozen prebiotic Qiuzi pear product and a processing method thereof. Background technique [0002] Pear is the main fruit in the north. Pear has many functions such as clearing heat and detoxifying, moistening dryness and relieving cough, promoting body fluid and reducing phlegm, nourishing body and eliminating diseases, etc. It is a fruit with both diet and therapy. However, the pears of the Qiuzi pear system have an obvious post-ripening process. Before post-ripening, the fruit is hard and the flesh feels woody, so it cannot be eaten directly. After post-ripening, the fruit is soft and juicy, with an excellent taste, but it is difficult to store. 1~2 Weeks will lose its edible value. Therefore, Qiuzi pears can rarely be stored for a long time and are only consumed as seasonal fruits. However, in Northwest China, especially Gansu, Qin...
