Preparing method of water hyacinth fermented protein powder

Abstract

The invention discloses a preparing method of water hyacinth fermented protein powder. The preparing method comprises the following steps that firstly, by weight, 80 parts of water hyacinth is dried at the temperature of 45 DEG C until the water content is 65%, and then smashing is conducted; secondly, by weight, 20 parts of bran is added into the smashed water hyacinth obtained in the first step;thirdly, 1% of nutritive salt solution is added into the mixture obtained in the second step, wherein the nutritive salt solution comprises 0.08% of ammonium sulfate, 0.12% of monopotassium phosphate, 0.05% of magnesium sulfate and 100 ml of water; fourthly, the mixture obtained in the third step is heated at the temperature of 121 DEG C for 20 min for sterilization, and a culture medium is prepared; fifthly, aspergillus niger, geotrichum candidum and yeast are inoculated into the mixture obtained in the fourth step in the ratio of 1:1.5:1.5 at the temperature of 28 DEG C, and closed cultureis conducted for 72 hours. According to the characteristics of the water hyacinth, the yeast, the aspergillus niger and the geotrichum candidum are selected for fermentation in the specific proportion, and water hyacinth resources are utilized maximumlly.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a preparation method of water hyacinth fermented protein powder. Background technique [0002] Water hyacinth is an invasive alien species in my country and one of the top ten harmful weeds in the world. It often causes ecological harm due to its explosive growth, but it is also a beneficial material for water purification. Using water hyacinth as a feed resource can not only solve the problem of home At the same time, the problem of insufficient feed resources for livestock and poultry can also be a treasure; in the current stage, water hyacinth is mostly used as roughage, but as roughage, it has the problems of difficult storage, inconvenient transportation and single feed ingredients. , there is a lack of a method for fermenting single-cell protein by using water hyacinth, so that the protein powder made from water hyacinth can be nutritious and easy to store.
