Description
Procédé de fabrication d'une farine à faible pouvoir calorifique Le brevet principal No 379247 a pour objet un procédé de fabrication d'une farine à faible pou voir calorifique. Ce procédé est caractérisé par le fait que l'on mélange, en présence d'un liquide ou en ajoutant ensuite un liquide,
au moins un poly- saccharide ne libérant pas dé sucre assimilable au cours de la digestion avec au moins une protéine capable de devenir insoluble sous l'effet de la cha leur, on façonne la pâte ainsi obtenue en corps ayant une grande surface, on la sèche puis chauffe à une température entre 1000 et 2500 C, le produit étant ensuite moulu et éventuellement mélangé avec une protéine ayant les propriétés physiques du gluten de blé.
On a maintenant trouvé qu'il est très avantageux d'utiliser dans ce procédé comme polysaccharide la caroubine, c'est-à-dire la farine-fleur dé caroubes. L'expérience a montré qu'on obtient avec cette ma tière première peu coûteuse les résultats les meilleurs lorsqu'on la soumet préalablement à une hydrolyse acide légère.
On peut effectuer l'hydrolyse soit avec une pâte aqueuse de caroubine, soit avec une sus pension de caroubine dans de l'alcool éthylique, iso- propylique, acétone ou autre solvant approprié que l'on peut facilement éliminer par la suite. 11 est judi cieux d'ajouter à une telle pâte ou suspension de l'acide chlorhydrique ou un autre acide fort, puis on chauffe jusqu'à l'obtention du degré désiré d'hydro lyse ;
on neutralise ensuite avec une base, par exem ple de la lessive de soude ou du carbonate de sodium et, s'il y a lieu, on élimine le solvant. <I>Exemple 1</I> On malaxe 95 g de farine de caroubine avec un mélange de 250 cm3 d'eau et 5 cmS d'acide chlor hydrique à 37 % jusqu'à l'obtention d'une pâte. La pâte est alors chauffée à 80o pendant 75 minutes et, en ajoutant 2,3 g de soude caustique d'ans 2.0 em3 d'eau, on la neutralise au pH 6,5.
A la pâte ainsi obtenue on ajoute, soit directement, soit après sé chage préalable, 5 g de protéine d'arachide dans 30 cm3 d'eau. La pâte obtenue est extrudée sous forme de vermicelles. qui sont .séchés pendant 5 heu res à 400 et ensuite chauffés durant 8 minutes dans un four à 200 .
Le produit obtenu est ensuite moulu et mélangé avec 20 parties de gluten de blé sec, de manière à obtenir une farine. La farine ainsi obtenue peut être utilisée pour la confection des aliments dié tétiques.
<I>Exemple 2</I> On met 100 g de caroubine en suspension dans 200 cm3 d'alcool éthylique et on ajoute 5 cm3 d'acide chlorhydrique à 37 %.
Tout en la remuant, on chauffe la suspension pendant 2 heures à la tempé rature de reflux (80o). La suspension est ensuite fil trée, on lave le résidu à trois reprises avec chaque fois 50 cm3 d'alcool éthylique et on sèche à 60 . On continue à traiter la farine ainsi obtenue comme il est décrit dans l'exemple 1,
en utilisant de l'oval bumine au lieu die protéine d'arachide.
Process for the production of a flour with a low calorific value The main patent No. 379247 relates to a process for the manufacture of a flour with a low calorific value. This process is characterized by the fact that one mixes, in the presence of a liquid or by then adding a liquid,
at least one polysaccharide which does not release assimilable sugar during digestion with at least one protein capable of becoming insoluble under the effect of heat, the dough thus obtained is shaped into a body having a large surface area, it is formed. dries then heated to a temperature between 1000 and 2500 C, the product then being ground and optionally mixed with a protein having the physical properties of wheat gluten.
It has now been found that it is very advantageous to use carob, that is to say locust bean flour, as a polysaccharide. Experience has shown that the best results are obtained with this inexpensive raw material when it is first subjected to light acid hydrolysis.
The hydrolysis can be carried out either with an aqueous carob paste or with a suspension of carobin in ethyl, isopropyl alcohol, acetone or other suitable solvent which can be easily removed later. It is advisable to add hydrochloric acid or another strong acid to such a paste or suspension, followed by heating until the desired degree of hydrolysis is obtained;
it is then neutralized with a base, for example sodium hydroxide solution or sodium carbonate, and, if necessary, the solvent is removed. <I> Example 1 </I> 95 g of carob flour are kneaded with a mixture of 250 cm3 of water and 5 cmS of 37% hydrochloric acid until a paste is obtained. The paste is then heated at 80 ° for 75 minutes and, by adding 2.3 g of caustic soda of 2.0 em3 of water, it is neutralized to pH 6.5.
To the paste thus obtained is added, either directly or after prior drying, 5 g of peanut protein in 30 cm3 of water. The dough obtained is extruded in the form of vermicelli. which are dried for 5 hours at 400 and then heated for 8 minutes in an oven at 200.
The product obtained is then ground and mixed with 20 parts of dry wheat gluten, so as to obtain a flour. The flour thus obtained can be used for the preparation of dietetic foods.
<I> Example 2 </I> 100 g of carobin are suspended in 200 cm3 of ethyl alcohol and 5 cm3 of 37% hydrochloric acid are added.
While stirring, the suspension is heated for 2 hours at reflux temperature (80o). The suspension is then filtered off, the residue is washed three times with 50 cm3 of ethyl alcohol each time and dried at 60. The flour thus obtained is continued to be treated as described in Example 1,
using oval bumine instead of peanut protein.
