Embodiment Construction
[0011] In the present invention, pumpkin is used as raw material, and the edible yellow pigment in the pumpkin is extracted by extraction method. The process steps of the present invention are as follows: adding ethanol with a solid-liquid ratio of 1:10 to 1:30 in the pumpkin for extraction, The ethanol concentration is 40-100%, the extraction temperature is 30-90°C, and the extraction time is 2-6 hours.
[0012] In the present invention, the ratio of solid to liquid, ethanol concentration, extraction temperature and extraction time are selected as factors affecting the extraction rate of yellow pigment.
[0013] As a preferred solution, the process steps of the present invention are: leaching temperature 70 °C, leaching time 6 h, solid-liquid ratio 1:20, ethanol concentration 90%.

The process comprises the step of adding ethanol with a material-liquid ratio of (1:10)-(1:30) in the pumpkin to extract, wherein the concentration of ethanol is 40-100%, the extraction temperature is 30-90 DEG C and the extraction time is 2-6 hours.
Description
technical field [0001] The invention belongs to the technical field of food, and more specifically relates to a process for extracting edible yellow pigment. Background technique [0002] The common name of pumpkin is squash, pumpkin, and pumpkin, and it is an annual vine herb. The stem is several meters long, rooted at the nodes, strong, with ribs and grooves, covered with short bristles, and the tendrils are divided into 3 to 4 forks. The flowering period is from May to July, and the fruiting period is from July to September. Native to southern Asia, it is cultivated all over the world. The fruit is used as a vegetable; the seeds contain oil and are edible, and the seeds (pumpkin seeds) and melon pedicles are often used as medicine, which can repel insects, strengthen the spleen, and produce breast milk. [0003] Pumpkin contains starch, protein, carotene, vitamin B, vitamin C, calcium, phosphorus and other ingredients. It is rich in nutrients and is a vegetable that i...
