Can rapeseed be refrigerated after blanching

After blanching rapeseed, it can be refrigerated in the refrigerator, but attention should be paid to the storage method and time. Cold storage of blanched rapeseed can help extend its shelf life, but prolonged storage may lead to nutrient loss or a deterioration in taste. Before storing blanched rapeseed in the refrigerator, it is necessary to drain the water and package it with plastic wrap or sealed boxes to avoid contact with perishable foods such as raw meat and seafood. The refrigeration temperature is controlled at 0-4 degrees Celsius and can be stored for 1-2 days. The blanching process can reduce some oxalic acid and pesticide residues, but water-soluble nutrients such as vitamin C may be lost with blanching. It is recommended to consume them as soon as possible after refrigeration. If not properly sealed or refrigerated for more than 3 days after blanching, yellowing, softening, or microbial growth may occur. Part of the chlorophyll that is sensitive to low temperatures will gradually decompose, resulting in a dull color. Long term refrigeration may also produce nitrite, especially repeated thawing can accelerate spoilage. In special circumstances such as when rapeseed is no longer fresh or when the refrigerator temperature is unstable, it is not recommended to store it refrigerated.

It is recommended to blanch in batches according to the amount consumed in daily diet. Eating it now can better preserve nutrients. Refrigerated rapeseed can be quickly stir fried, cold mixed, or used to make soup, avoiding the damage of texture caused by secondary heating. Pairing with ingredients such as mushrooms and tofu can increase dietary fiber and plant protein intake. It is important to heat refrigerated dishes thoroughly after removal. People with weak gastrointestinal function should reduce the consumption of overnight blanched vegetables and switch to rapid freezing storage to extend the shelf life to one month.
