Embodiment Construction

[0013] The technical scheme adopted in the present invention comprises the steps:

[0014] 1) Sorting: Raw materials are sorted on the basis of first-in first-out according to different acquisition time, variety, and origin. The sorted pears are put into three plastic boxes, one plastic box holds moderately ripe pears, one holds pears that cannot be put into processing yet and needs to be ripened, and the other holds pears that do not meet the processing requirements defective pears. After 4-6 hours, pears that cannot be processed but need to be ripened are sorted according to the above steps;

[0015] 2) Alkali drenching and peeling: Arrange the pits of pear slices after excavation on the conveyor belt in a single layer, and then enter the drenching machine. The time of alkali drenching is controlled at 25-45 seconds, depending on the maturity of pears. The concentration, temperature and time of lye leaching are based on the ability to remove the pear skin without damaging ...

Abstract

The invention provides an european pear can processing technology capable of preventing the nutrient loss. The processing technology is characterized by comprising the following steps of 1) sorting, namely, sorting out raw materials based on a first-in and first-out principle according to different procurement times, varieties and places of origins; 2) spraying alkali and peeling, namely, arranging white peach which is divided into two halves and released from kernel in a single layer on a conveyor belt, wherein the kernel cavity is kept downward; 3) pre-boiling, namely, pre-boiling with a spiral pre-cooking machine, wherein the pre-cooking time is determined according to the technology requirement; 4) filling soup and sealing, namely, adding white granulated sugar to a pot; heating until slightly boiling; maintaining for 5 minutes; and uniformly agitating; and 5) sterilizing and cooling, namely, sterilizing at the high temperature through a continuous sterilizer. The european pear can processing technology has the beneficial effects that the peeling efficiency can be obviously improved after the treatment by adopting the technology, the peeling efficiency and the appearance quality can also be improved; in addition, the loss of sugar, protein, mineral substances, vitamin and other nutritional ingredients of an european pear can are obviously decreased, and thus the nutritional quality of the european pear can is improved, and the market competitiveness of the european pear can is enhanced. The european pear can is convenient to carry, high in storage resistance, and is a nutritional can with the market potential.

Description

technical field [0001] The invention relates to a canning process, in particular to a canned pear processing technology for preventing nutrient loss. Background technique [0002] Yang pear, also known as Ba (Ba) pear, eggplant pear, gourd pear, and sun pear, is a cultivated variety of Western pear native to Europe in Rushan. Pear has high nutritional value and is a common and commonly eaten fruit. It has the effects of moisturizing the lungs and reducing phlegm. In addition to eating fresh, it can also be made into a variety of processed products, such as pear paste, preserved pears, canned pears, and pear wine. The pear fruit is short gourd-shaped, with short and thick stems, a single fruit weighs 250 grams, and the fruit shape index is about 1.2. Ripe fruit has bright yellow skin, white flesh, delicate texture, juicy and no slag, sweet and delicious, slightly sour, rich fruity aroma, 16.5% soluble solids, and is the best product in the genus Pear. [0003] In the curre...
