Abstract

The invention discloses a resource utilization method of incompletely ripe tomatoes, and belongs to the technical field of food ingredient production. According to the method, tomatoes which are not completely ripe or tomato products which are not completely ripe are used as raw materials, moisture content of the tomatoes is controlled to be 20%-40%, then ethyl alcohol is used as an extracting agent for separation and extraction, and an extract containing phytofluene and phytoene and an extract containing lycopene are obtained respectively. According to the method, the moisture content is adjusted to be 20%-40%, alkaloid contained in the raw materials is removed to the maximum extent, meanwhile, content of lycopene, phytofluene and phytoene is not affected, graded extraction is conducted through solubility difference, and a product with a content of phytofluene and phytoene being 0.9-1.1% is obtained; meanwhile, subsequent extraction of lycopene with strong hydrophobicity is also facilitated, and extraction rate is as high as 85%.

Description

technical field

[0001] The invention relates to a resource utilization method of immature tomatoes, which belongs to the technical field of food ingredient production. Background technique

[0002] The ripening process of tomatoes can be roughly divided into four periods, namely the green ripening period, the discoloration period, the hard ripening period and the fully ripened period. At present, in the process of tomato processing (such as the production of tomato sauce), tomatoes in the fully ripened period are used as raw materials. As many as 20%-25% of immature tomatoes will be sorted out and directly discarded as waste, resulting in a huge waste of resources and a greater degree of pollution to the environment.

[0003] Tomatoes can form a variety of secondary metabolites during the growth process, such as carotenoids, polyphenols, alkaloids, etc. The most important alkaloid in tomato is tomatine, which is composed of a tetrasaccharide side chain and a steroidal aglyc...
