Embodiment Construction

[0014] The present invention uses tiger Pilan as raw material, utilizes ultrasonic method to extract, and process step is:

[0015] 1. Cleaning, drying and crushing;

[0016] 2. Leaching

[0017] Adding the ethanol solution with a solid-liquid ratio of 1:5 to 1:30 in the tiger Piran dry powder, the mass concentration of the ethanol solution is 10 to 60%, the pH value of the adjustment system is 6 to 13, and 5 ~60min;

[0018] 3. Filter, concentrate the supernatant, and dry.

[0019] As a preferred solution, the process steps of the present invention are as follows: 40% ethanol is used as the extractant, the ratio of solid to liquid is 1:20, the pH of the system is adjusted to 5, and ultrasonic extraction is performed at 60° C. for 20 minutes.

[0020] The present invention selects extractant type, extractant concentration, solid-liquid ratio, extraction temperature, extraction time as the factors affecting the extraction effect of tiger skin blue green pigment, as shown in ...

Abstract

The invention relates to an extraction process for a food pigment. The invention provides an extraction process for a green pigment, and the process has the advantages of simple operation, a high extraction rate and strong stability of a prepared product. According to the invention, sansevieria trifasciata prain is used as a raw material, an ultrasonic method is used for extraction, and the process comprises the steps of cleaning, drying, crushing, extraction, filtering, condensation of a supernatant and drying.

Description

Technical field: [0001] The present invention relates to a kind of extraction technology of edible pigment, more specifically, relate to a kind of extraction technology of green pigment. Background technique: [0002] Tiger Pilan, also known as Phnom Penh Sansevieria and Yellow Edge Sansevieria, belongs to the genus Sansevieria in the Agaveaceae family. Tiger Pilan is native to Africa and India. It is a perennial herb with many varieties. Tiger Pilan leaves are firm and upright, with gray and white and dark green tiger tail-shaped stripes on the leaf surface, and its posture is firm; it has strong adaptability to the environment, easy to reproduce, and fast growth. It is a kind of ornamental, greening, and fiber raw material. A whole body of plants. [0003] Food color is one of the important factors that constitute the sensory quality of food. Therefore, pigment is an important part of food additives. However, with the increase in the use of synthetic pigments, safety i...
