Definitions
- the present invention relates to water-soluble fractions of clear plants, particularly a solution of clear corn steeping water and a solution of clear potato solubles. These can be stored for several days at room temperature without the appearance of a deposit of insoluble materials.
- Corn soaking water commonly referred to by the English term “com-steep”, by those skilled in the art, designates an aqueous solution resulting from soaking corn.
- Soaking the corn in water constitutes the first step in the extraction of starch in wet starch manufacturing. This quenching allows the corn grains to swell and the highly fermentable soluble materials contained in these grains to be eliminated. It consists of maintaining the corn placed in silos for a given time in hot water containing a small quantity of sulfur dioxide, in order to facilitate the subsequent separation of protein-cellulose-starch, and to also prevent the growth of undesirable microorganisms. These quenching waters are then most often concentrated, typically by evaporation.
- the first consists of a diffusion of soluble materials from the corn grain towards the quenching water, while the second consists of fermentation of these soluble materials in the quenching water.
- quenching water by lactic bacteria the quenching conditions (presence of sulphites, reducing sugars, temperature) being favorable to the rapid development of this bacterial flora.
- corn steeping water constitutes a source of organic nitrogen of choice by the distribution and forms of its amino acids: free, peptide, protein as well as a source of carbon (lactic acid) and phosphate (acid phytic) with a delayed effect.
- a high content of vitamins and trace elements completes the interest of corn steep water as a nutrient source for the growth of microorganisms and the induction of secondary metabolites when corn steep water is associated with one or several carbon sources (glucose, maltodextrin, starch, sucrose, etc.).
- yeast extracts which represent the reference material in this field, and which are also used in human and animal food.
- Corn soaking water is also an excellent nutrient source for growing plants in the ground or above ground. Its richness in nitrogen, phosphate and potassium nutrients is particularly suited to the needs of growing plants. It also contains numerous micro and trace elements, a rich salt content as well as amino acids/peptides with potential biostimulation effects on plant growth. Its use makes it possible to nourish the plant but also to protect it from various diseases likely to compromise its growth.
- Patent application JP2001204410 proposes using a centrifugation process in order to eliminate these insoluble particles which settle and to stabilize the corn soaking water.
- the process is not optimal because the corn soaking water obtained is not completely clear (7% minimum volume precipitation in the supernatant). Such a product is therefore likely to pose a problem during implementation, for example by blocking dispersion nozzles when spreading on crop fields.
- This process for treating a corn steep water solution comprises the sequence of the following steps: a) adding salts of neutral divalent cations to the corn steeping water solution; b) adjusting the pH of the corn steep water solution to between 6 and 8; c) separation of the liquid and solid phase of the solution obtained in step b) and d) Drying of the liquid phase obtained in step c) in order to obtain powdery corn quenching water. If this solution makes it possible to obtain clear corn soaking water that is stable upon sterilization, its composition is changed by the introduction of salts. If this modification is useful for particular applications, it may be advantageous to retain the initial protein content as well as the composition of the original corn steeping water.
