Definitions
- TITLE Process for obtaining a agroliant made from starches or starchy meals, of cereal origin or not.
- the invention relates to a process for obtaining a agroliant made from starches or starchy meals, of cereal origin or not.
- starch is one of the most well known biopolymers.
- Raw materials are renewable and highly available.
- the present invention aims to improve the water behavior of a starch-based vegetable binder. It finds a particular application for example, in the assembly of solid elements or particles, the surface treatment or for the production of aggregates or their coating.
- the agroliant according to the invention may optionally serve as a matrix for designing composite materials optionally reinforced with plant fibers. It can also serve as a basic material for the production of agrogranulates. Areas of use include construction and packaging.
- the wheat flour glue is an old glue, still used today by antique restorers. Vegetable glues were often based on starchy materials (containing starch), added to other substances to give them body. Flour glues (rye or wheat) or glue pastes, starch glues (potatoes), dextrin (resulting from the action of an acid on starch) and chestnuts are examples the most famous.
- Starch Under the action of hot water, starch swells and hardens upon drying. This swelling is particularly clear from 55 ° C and is continues at higher temperatures. Starch molecules have many hydroxide groups that react with water molecules attracting and trapping them.
- the smaller amylose molecules separate from the swollen starch grains to form a 3D network, in turn trapping water molecules.
- the swollen starch occupies a volume equal to 30 times its initial volume. On cooling, the starch becomes en masse.
- Plasticized starch sometimes misnamed "thermoplastic starch” can be obtained through the addition of glycerol or other plasticizers.
- the plasticized starch can be implemented by conventional tools of the plastics industry. Unfortunately, its use is limited because it has a high sensitivity to water and limited mechanical properties compared to a conventional thermoplastic.
- starch-based materials are used in applications in the paper and cardboard industry, textiles and adhesives, but also as filler in synthetic or natural polymers.
- Hongjie An et al (An Hong, Hongshun Yang, Zhongdong Lin, Zhang Zhizhon: Effects of heating modes and sources on nanostructure of gelatinized starch molecules using atomic force microscopy LWT-Food Science and Technology, Volume 41, Issue8, November 2008 , Pages 1466-1471) have studied the effects of microwave heating on the nanostructure of starch molecules by atomic force microscopy (AFM).
- AFM atomic force microscopy
- the potato and corn starches were subjected to convection and microwave heating. Potato starches exposed to microwave radiation create networks of 0.3 to 11 nanometers in height while maize starches do not form a network. Heating influences the starches of potatoes much more than those of corn.
- Dobircau et al (L.Dobircau, PASreekuman, R.Saiah, N.Leblanc, C.Terrié, R.Gattin, JMSaiter-Wheat flour thermoplastic matrix reinforced by waste cotton fiber: Agro-green-composites-Composites: Part A 40 ( 2009) 329-334) made by extrusion 100% natural composites from agromaterials with a matrix based on wheat flour and for the reinforcement of cotton fibers from recycling.
- Delia Valle (Delia Valle, G., Vergnes, B., Colonna, P., Patria, A. Relationships between rheological properties of molten starches and their expansion behavior in extrusion J.Food Eng 31, 277-296 (1997) ) studied the expansion behavior of liquid starches by extrusion and showed that the expansion increases with the percentage of amylose.
- siccativity of an oil depends on its degree of unsaturation.
- a monounsaturated oil (a single double bond) is in principle semi-drying, a bi-unsaturated oil (two double bonds) is drying, and a tri-unsaturated oil (three double bonds) is extremely drying.
- the siccativity covers a phenomenon of oxygen fixation in an oleaginous medium, thereby causing its solidification by polymerization and crosslinking. Siccativity is also influenced by other factors, including the shape of molecules and the position of double bonds in molecular chains. These factors characterize the properties of each oil. Fractional biomaterial processing tests have already been carried out.
- frying is a food cooking system consisting of a substitution on the one hand of the water contained in the food by the fat of the frying in which the food is immersed. At first, a large part of the water contained in the food evaporates by the heat transmitted by the oil. Then the hot oil enters the food.
- the test pieces were dried by steaming.
- the immersion coating protocol consisted of immersing the specimens in the oil at room temperature and then draining them on a metal grid and finally, drying them by ventilating at 80 ° C in order to accelerate the crosslinking of the fatty acids. .
- the specimens were immersed in oils heated to 190 ° C and then drained, cooled and conditioned in a climatic chamber at 25 ° C as in the case of dip coating.
- the object of the present invention is to improve the water characteristics of agroliants made from starches or starchy meals, cereal origin or not.
- It may include flour, wheat, rye, barley, corn, chestnuts, horse chestnut, millet, rice, buckwheat, quinoa, spelled, soybeans, peas, potatoes.
- the invention has an increased interest when it comes to efficiently consume flour unfit for consumption (food).
- the invention relates to a process for obtaining a agroliant made from starches or starchy meals, of cereal origin or not, characterized in that at least:
- the invention arose from the discovery by the inventor that the combined presence of lime and dust from scutching, including linseed scouring improves the water resistance of a starch-based agroliant .
- the mixture of step a) comprises
- the lime may be aerial lime (calcium hydroxide (Ca (OH) 2 ;
- Agroliant can be subjected to a heat treatment more particularly of the type convective heating or microwaves;
- the solvent may be water, optionally partially substituted with glycerol to improve the plasticity and impermeability; -
- the solvent including water can also be added sucrose to increase mechanical performance and delay setting;
- Agroliant can be foamed, especially protein, especially from hemoglobin of animal blood;
- the agroliant can be expanded by chemical reaction in the mass or by adding a preformed foam;
- the agroliant can optionally be colored in the mass by the addition of pigments;
- the agroliant may optionally be supplemented with mineral or organic fillers and in particular lignocellulosic fillers, in the micronized or granular state;
- the mixture can be fiber also including plant fibers
- the said fibers may be lignocellulosic materials selected from the group of cereal byproducts such as flax or hemp grinding products, beet pulp, shives flax, hemp, straw, corn flakes, colza, silo refusal;
- any other lignocellulosic coproduct derived from agricultural production, or growing in the wild, or from logging, may be used.
- - Starch meal may be selected from the following group: wheat, rye, barley, maize, chestnut, horse chestnut, millet, rice, buckwheat, quinoa, spelled flour , soy, peas, potatoes, cassava;
- the product loaded, or not, possibly fiber can be shaped by casting, thermocompression, or extrusion, or by any other forming process for the production of machinable plates of varying thicknesses;
- the agroliant can be spread in thin layers, protective or to assemble rigid structural elements including particle board, fiber board or wood boards, after cooling, the mixture hardening to give more or less rigid materials depending on the starting composition;
- the water resistance can be further improved by frying said agroliant, after the shaping step;
- the dust of scutching is particularly resulting from the treatment of linen.
- hemp scutching dust is also suitable.
- the wheat flour used is of type 55 in the classification of flours (that is to say that the flour produces less than 0.55 g of ash per 100 g of flour).
- the composition of the mixture with the solvent (water) is as follows (ratio by mass):
- This composition is subjected to a microwave treatment in a domestic microwaves oven for a time which depends on the mass of material treated, ie 1 min at 900 Watts per 100 g of the mixture with the solvent (water).
- the maximum saturation rate is 180%; the destruction of the sample by decohesion is obtained after 48 hours of immersion in water.
- the maximum saturation rate is determined as follows.
- a material is prepared according to Example 1. After forming, a frying treatment is carried out with a fat such as linseed oil or sunflower oil. This frying is followed by drying at medium temperature to accelerate the polymerization (200 ° C for 10 minutes and then drying at 100 ° C). It has been noticed that the oil having penetrated inside the sample is polymerized. After nine days of immersion in the water, the maximum saturation rate dropped to 45% and the material is still not destroyed.
- a fat such as linseed oil or sunflower oil.
- a formulation material identical to that of Example 1 is shaped without microwave treatment. A more rigid and water-resistant material is obtained than with microwave treatment. After seven days of immersion in water, the material is not destroyed and the maximum saturation is 66%.
- Example 1 A mixture in the same proportions as in Example 1 is formulated. However, wheat flour is replaced by buckwheat flour (which does not include gluten, unlike wheat flour). This product is subjected to a microwave treatment. After seven days of immersion, the cohesion of the material is still maintained and the maximum saturation rate is 10g%. Without microwave treatment, the maximum saturation rate is 47% after seven days.
- a composition is produced in the same proportions as in Example 1, replacing the wheat flour with oatmeal.
- the agroliant has a maximum saturation of 88% after seven days of immersion.
- the sample is destroyed after 48 hours of immersion and the saturation is 194%.
- Example 1 The thermal and mechanical characteristics of Example 1 are illustrated in the following two tables (Table 1 and Table 2).
- Table 1 and Table 2 A third table illustrates the water performance of the agroliants of Examples 2 to 6.
- Density materials of the order of 800 kg / m J to 900 kg / m -1 .
