Abstract
Process for the manufacture of quick-dissolving powder products from pulse vegetables wherein the dry legumes are firstly so finely milled under dry conditions that even the shells (Exosperm) are disintegrated and inseparable from flour. Next, the milled legume is mixed with .alpha.-amylase and water to form a suspension which is submitted to a continuous process consisting successively of a short, intensive boiling phase, and reactions phase to decompose at least a part of the starch in the boiled suspension by the .alpha.-amylase, and then a drying phase.
Claims9
A process for manufacturing a powdered, instant soup or puree product for human consumption from pulse vegetables comprising the steps of
- a. finely milling whole pulse seeds under dry conditions to such extent that the exosperm parts are disintegrated and are indiscernible and inseparable from the flour parts;
- b. mixing said finely milled pulse material with water and .alpha.-amylase to form a suspension;
- and
- c. continuously conveying said suspension successively through a short, intensive heating phase wherein boiling of the suspension is effected in a time period on the order of seconds so as to effect rapid hydrolysis without destroying the natural taste of the pulse material and without deactivating the .alpha.-amylase, a longer reaction phase having a duration on the order of minutes wherein decomposition of starch in the pulse material by the .alpha.-amylase continues without further heating, and a drying phase wherein the suspension is dried and the .alpha.-amylase is deactivated,
- d. the .alpha.-amylase being active throughout the entire period between its introduction and the drying phase and serving to convert a portion of the starch in the pulse material to maltose and thereby eliminate the bitter, raw taste of the pulse.
A process of preparing a soup or puree for human consumption using the product produced by the process defined in any one of the preceding claims which comprises the step of mixing said product with water.
The product produced by the process defined in any one of claims.
