Problems solved by technology

Chinese patent document CN200710122639.7 discloses a treatment method for marigold fermentation press liquid flower mud. This method achieves the purpose of recovering residual raw materials by adding an adsorption carrier to the wastewater. Due to the need to add an adsorbent, there may be subsequent pollution problem
[0004] At present, the drying process of marigolds before processing is to use direct-fired high-temperature drying, that is, to use coal or natural gas as a heat source, and use their flue gas to directly dry the fermented marigolds, which will lead to Harmful substances enter marigolds, and the granulation process of the current process is also carried out in an open environment, which will pollute marigold products and destroy the quality of lutein

Embodiment 1

[0033] The method for producing marigold granules in this embodiment includes fermentation, water squeezing, drying, and pulverization. The marigolds used are fresh marigold flowers picked that day. In the fermentation process, the marigold is fermented twice with a lactobacillus dilution, then extruded and dried, and then air-cooled to lower the temperature after drying, and then pulverized and granulated. The activity of Lactobacillus in the stock solution of Lactobacillus is 1.25×10 11 cfu / g.

[0034] The lactobacillus dilution used in the first fermentation is to dilute the lactobacillus stock solution to 0.15% with water, and then evenly spray it on the surface of the marigold. The fermentation temperature is controlled at 38 ° C, and the fermentation time is 4.5 days; The lactic acid bacteria dilution used is to dilute the lactic acid bacteria stock solution with water to 0.75%, and then directly and evenly spray it on the surface of the marigold after the first fermen...

Embodiment 2

[0038] The process of this embodiment is basically the same as that of Embodiment 1, the difference is:

[0039] The marigolds used were fresh marigold flowers picked the day before.

[0040] The lactic acid bacteria used in the two fermentation processes are Streptococcus thermophilus, and the activity of Streptococcus thermophilus in the stock solution of Streptococcus thermophilus is 1×10 11 cfu / g. The Streptococcus thermophilus diluent used in the first fermentation is to dilute the stock solution of the Streptococcus thermophilus to 0.1% with water, the fermentation temperature is controlled at 35° C., and the fermentation time is 4 days. The Streptococcus thermophilus diluent used during the second fermentation treatment is to dilute the Streptococcus thermophilus stock solution to 0.05%, the fermentation temperature is controlled at 30° C., and the fermentation time is 24 hours.

[0041] When filtering the extruded waste water during the extrusion dewatering process a...

Embodiment 3

[0044] The process of this embodiment is basically the same as that of Embodiment 1, the difference is:

[0045] The lactic acid bacteria used in the two fermentation processes were Leuconostoc, and the Leuconostoc activity in the Leuconostoc stock solution was 1.5×10 11 cfu / g. The Leuconostoc diluent used in the first fermentation is to dilute the Leuconostoc stock solution with water to 0.2%, the fermentation temperature is controlled at 40° C., and the fermentation time is 5 days. The Leuconostoc diluent used in the second fermentation treatment is to dilute the Leuconostoc stock solution to 0.1%, the fermentation temperature is controlled at 35° C., and the fermentation time is 48 hours.

[0046] When filtering the extruded waste water during the extrusion dewatering process after fermentation, the filtration precision of the plate and frame filter used is 500 mesh, and the precision of the ceramic filter membrane is 500nm. After such treatment, the solid content in the f...

Abstract

The invention discloses a tagetes erecta particles production method capable of increasing xanthophyll content, which belongs to the field of natural pigment processing. According to the method, the picked fresh tagetes erecta is subjected to two-time fermentation by using a lactic acid bacteria diluent, physical extruding, drying and dehydrating, and water cooling, and then the material is subjected to crushing granulation under inert gas protection to obtain the tagetes erecta particles. A plate and frame filter as well as membrane filtration are used in order for re-covering residual tagetes erecta and xanthophyll in waste water after physical extruding, and the xanthophyll content during tagetes erecta processing is increased. The xanthophyll content in the produced tagetes erecta particles is high, and the waste water can be better processed.

Description

technical field [0001] The invention belongs to the field of natural pigment processing, and relates to a method for pretreating marigold as a raw material for extracting lutein before extracting lutein, and specifically refers to a method for preparing marigold granules. Background technique [0002] Marigold flowers are rich in lutein, and marigold is the main raw material source for extracting natural lutein. Before extracting lutein, marigolds need to be pretreated, fermented marigold flowers into granules, so that most of the lutein in marigold granules is in a free state, and after granulation, use organic solvents to extract free lutein After extraction, the resulting product is enriched with lutein extracts. The preprocessing process of picked marigolds before extracting lutein will have a great influence on the content of lutein in marigold granules. At present, the more common marigold pre-processing process mainly includes marigold flower fermentation, material ...
