Problems solved by technology

However, the traditional dried strawberries are processed by the process of "selecting materials-cleaning-removing fruit stems-adding sugar and cooking-filtrate-baking-inspection". The process is simple and rough, which not only loses a lot of nutrient content, but also makes its color , The taste loses the original characteristics of strawberry

Embodiment 1

[0024] A kind of processing method of dried strawberry, take processing 100kg strawberry raw material as example: select the high-quality strawberry that is fresh, big, no insect damage, no scar, strong fragrance, sweet and sour taste as raw material, after removing impurities and fruit pedicles, use " Cleaning - piercing - hardening and color protection - rinsing - sugar staining - baking - softening - inspection and assembly" process, the specific steps are:

[0025] 1) Cleaning: Under the temperature condition of 0-5°C, put the qualified strawberries in the rotating sieve basket, wash them with flowing light salt water for 2-3 times, spread them separately until there are no water drops on the surface of the strawberries. Salt water refers to a sodium chloride solution with a concentration of 0.1 to 0.5 mol / L;

[0026] 2) Puncture: Under the condition of low temperature 3~5℃ and low pressure 45~55kPa, clean strawberries are subjected to puncture treatment, the pore diameter...

Embodiment 2

[0034] Take the processing of 100kg strawberry raw material as an example: according to the processing method of dried strawberries described in Example 1, the difference is that the hardened color protection solution described in step 3) is made of light salt water and calcium chloride at a ratio of 1:0.005 Mixed than inverted.

Abstract

The present invention discloses a dried strawberry processing method, wherein fresh strawberries are adopted as a raw material, impurity removing and pedicel removing are performed, and the process comprising washing, puncturing, hardening color protecting, rinsing, sugaring, baking, samming and inspection packing is used to process so as to obtain the dried strawberry. The method is characterized in that a hardening color protecting liquid obtained by mixing light salt water, calcium chloride and sodium sulfite according to a ratio of 1:0.005-0.01:0-0.002 is used to carry out the hardening color protecting, such that the dried strawberry product has advantages of bright color, pure taste, no sticking, and no dry and hard property; and during the rinsing process, the intracellular Na<+> and the intracellular Cl<-> perform the extracellular movement due to the concentration difference, such that the external movement of the nutrition substance ions is reduced so as to reduce the nutrient loss.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a processing method of dried strawberries. Background technique [0002] Strawberries are rich in fructose, sucrose, citric acid, malic acid, salicylic acid, amino acids, calcium, phosphorus, iron and other minerals, and also contain a variety of vitamins, especially vitamin C content as high as 0.06%. Sweet and sour fruit with high nutrition. Modern Chinese medicine believes that strawberries are sweet in taste and cool in nature. Coronary heart disease; and foreign medical research has found that strawberries contain anti-cancer ingredients, which can inhibit the growth of tumor cells and have high medicinal and medical value. [0003] In recent years, with the expansion of planting area and the improvement of planting technology, strawberries have produced a large surplus while meeting the seasonal market demand. In order to solve the problem of strawberr...
