Low swelling starch
View Patent ↗This invention pertains to low swelling starches and their use as food texture modifiers. The invention further pertains to the method of using low swelling starches as fat substitutes in foods. The low swelling starches provide opacity, mouth-coating, and creaminess to foods.
1. A method comprising:
retorting a first food composition for a first retort time,
wherein the first food composition comprises a starch having a swelling volume of greater than 7 and less than 11 and a fraction of soluble starch that is less than 20% wt/wt and wherein the retort time is at least 20% less than a second retort time for retorting a second food composition having an identical composition as the first food composition except at least 25% by weight of the starch is replaced with a retort starch
wherein the swelling volume is measured as follows:
a) preparing a 5% starch slurry in 1% NaCI solution in a beaker;
b) heating the slurry in the beaker using a boiling water bath having a minimum temperature of 95° C. for 20 minutes, stirring for the first 3 minutes and then cover with a watch glass for the remaining time;
c) diluting the slurry to 1% and allowing to settle for 24 hours and optionally, waiting a total of 72 if the low swelling starch is a waxy rice starch to form a dilute settled slurry; and
d) extracting an aliquot of supernatant of the dilute settled slurry; and
e) using a refractometer or polarimeter to measure the concentration of starch in the supernatant; and
f) calculating the percent of swelling starch that is soluble.
2. The method of claim 1 , wherein the first retort time is at least 25% less than the second retort time.
3. The method of claim 2 , wherein the first retort time is at least 30% less than the second retort time.
4. The method of claim 1 , wherein the starch has a swelling volume from to 9 to 10 ml/g.
