Embodiment Construction

[0020] The process for extracting edible natural red pigment from psammophyte Nitraria japonica comprises the following process steps:

[0021] 1. Raw material processing

[0022] (1) Fruit cleaning (Although the fresh Nitraria fruit contains 85.5% to 89.5% of water, but because the core is large and hard, and contains rich colloid, it is difficult to squeeze the juice from the fresh fruit, so the method of drying the fresh fruit is often used Preserve the fruit.) The Nitraria dried fruit is manually or mechanically screened to remove sundries and surface adherents, then soaked in 0.2% sodium bisulfite for 5-20 minutes for surface disinfection, and then sprayed and washed by a vibrating sieve.

[0023] (2) Extraction Put the sterilized and cleaned fruit in a stainless steel basket, then immerse it in a cement pool coated with edible paint, add demineralized water 3 to 6 times the amount of dried fruit, and extract for 10 hours.

[0024] (3) After beating, deseeding and leachi...

Abstract

The present invention relates to an extraction process for extracting edible natural red coloring matter from psammophyte nitraria sibiria. Said invention uses the fruit of wild nitraria sibiria as raw material and adopts the processes of ethyl alcohol extraction, removing impurities, concentrating and drying so as to obtain the invented product which has high color fastness for protein, starch and sugar, etc. and can be used for coloring beverage, sweets, liquor and other foods.

Description

technical field [0001] The invention belongs to the field of food chemistry, and relates to a method for preparing edible natural pigments, in particular to a process for extracting edible natural red pigments from psammophyte Nitraria japonica. Background technique [0002] With the continuous deepening of research on the hazards of artificially synthesized food coloring to human health, its use is increasingly restricted. At the same time, with the enhancement of people's psychological needs of advocating nature, returning to nature, and safety first, natural pigments have been valued and developed rapidly. Although natural pigments are more expensive and are often limited by processing conditions, because they come from nature, they often have certain nutritional and health value, and even medicinal value. Therefore, as the voice of the "green movement" is getting louder and louder today, due to the willingness of consumers to accept it, the development prospects of natu...
