The growth of citronella and the determination of chlorophyll content in the leaves of plants is an important test. In practical applications, chlorophyll is a physiological and biochemical research of plants and post-harvest chlorophyll meter measurement parameters are also stored and processed. It is also an important indicator to measure quality. Dehydrated vegetables. Natural chlorophyll-derived foods from fruits and vegetables are natural colorants that can be used in a wide range of industries such as food and cosmetics.
Fresh, ripe, but not aged, red citrons are selected, rinsed with water and drained. After being chopped, a small amount of calcium carbonate and a small amount of cellulase are ground to neutralize the cell liquid to protect the chlorophyll and increase the leaching rate. After filtration using a Buchner funnel, the filtrate was concentrated by heating and evaporation in a water bath at 90C to 100C. Chlorophyll extraction, filtration, concentration, and other processes should be performed in a dark environment to prevent photolysis of chlorophyll and their contents can be determined by chlorophyll meter.
The best extraction conditions for red locust chlorophyll were acetone-dehydrated alcohol mixed extractant, extraction for 20 h, solid-liquid ratio of 1:8 and temperature of 60°C. Chlorophyll analyzer analysis showed that the primary and secondary factors affecting the chlorophyll extraction factors of red Toona sinensis were the ratio of material to liquid> extraction temperature> extraction time. Red cinnamomum chlorophyll is stable below 100°C. It has good stability at pH 6~10, but is easy to be photolyzed. It is stable to glucose but unstable to citric acid. Red citron has rich chlorophyll content and thermal stability. Very high, the extraction method established by the chlorophyll meter test is simple and easy to implement, and has a promising market prospect.
There was no significant change in the color of red citron chlorophyll extract after adding 0.1 g of glucose and 0.1 g of citric acid. The determination results of chlorophyll meter at wavelengths 663nm and 645nm showed that the proper amount of glucose had no significant effect on the stability of chlorophyll of red toon, but citric acid had a significant effect on its stability. This may be related to the fact that citric acid changes the acidity of the extract. Conditions related.
