Embodiment 1

[0009] Embodiment 1. Select 1000 grams of fresh and tender spinach according to the following formula proportions. After harvesting, cut off the roots to the stem plate in time, wash them with clean water, first scald the roots for 1 minute, and immediately put them into cold water after blanching to cool down to the center temperature. below 10°C. Drain off the water, spread them neatly in a 18cm×13cm grid, and freeze them in a quick freezer at around -35°C until the center temperature is below -18°C. Take out the frozen spinach from the plate, soak it in clean water at 3-5°C for 3-5 seconds, remove it immediately, wrap it with frozen clothes, put it in a polyethylene plastic bag and seal it, and store it in a freezer below -18°C refrigeration.

Abstract

The invention provides a novel low-temperature sterile refrigeration technology for spinaches. The technology has the advantages of being simple in storage method, and the like, and the spinaches are sweet and cool in taste, and have the effects of nourishing the blood and hemoslasis and retaining yin, moistening dryness, so that the spinaches are applicable to sufferers with hypertension, diabetes mellitus, tuberculosis, gastrointestinal dysfunction, chronic constipation and consumption sores. The novel low-temperature sterile refrigeration technology is achieved by the following steps: selecting 500-1000g of fresh and tender spinaches; timely cutting off the roots to the stem segments after harvesting; cleaning by clean water; firstly, burning the roots for 1 minute, and immediately feeding to cold water to cool after blanching until the center temperature is less than 10 DEG C; draining off water, and regularly paving into a lattice of 18cm*13cm; quickly freezing in an instant freezer at about -35 DEG C until the center temperature is less than -18 DEG C; taking out the frozen spinaches from a plate; dipping in clean water at 3-5 DEG C for 3-5 seconds, and timely fishing out; and packaging into a polythene plastic bag and sealing after coating by a frozen coating, and storing in a refrigeration house at a temperature below -18 DEG C.

Description

technical field [0001] The invention relates to a new technology of low-temperature aseptic refrigerated spinach. Background technique [0002] Spinach is one of the vegetables that everyone loves, but spinach is not easy to store and is easy to rot. If a large amount of spinach is transported long distances, it will cause heavy losses. Contents of the invention [0003] The purpose of the present invention is to overcome above-mentioned deficiency, a kind of low-temperature aseptic refrigerated spinach new technology is provided, [0004] It has the advantages of simple storage method and the like. Spinach is also known as spinach, commonly known as red-billed green parrot. Spinach is native to Nepal. According to historical records such as "Book of Tang" and "Tang Huiyao", in the 21st year of Emperor Taizong's Zhenguan (646 AD), King Nibhara sent envoys to Tang Dynasty to present spinach and other things. The Nibhara Kingdom in the Tang Dynasty is located in today's N...
