The present invention relates to a new formulation comprising L-theanine.
L-theanine is an amino acid. The human body does not produce this compound, and it is not essential for humans, but it has some very positive effects on the human body as it is described below.
L-theanine can be found naturally in green tea, black tea, and certain types of mushroom.
L-theanine has very interesting positive effects when consumed.
L-theanine may affect the levels of certain chemicals in the brain. These include serotonin and dopamine, which influence mood, sleep, and emotion, and cortisol, which helps the body deal with stress. A change in the balance of these chemicals can change a person's mood or stress levels.
Furthermore, several studies have suggested that L-theanine could help people relax before bedtime, get to sleep more easily, and sleep more deeply.
These benefits may result from the specific effects that the amino acid has on brain chemicals that play a role in sleep.
Furthermore, research suggests that the L-theanine in green or black tea may contribute to this feeling of relaxation by reducing a person's resting heart rate.
Furthermore, there are studies that indicate the consumption of L-theanine could improve a person's mental and physical health. It seems to have neuroprotective effects, which improves brain function.
On its own, L-theanine may improve a person's attention and reaction times. In combination with caffeine, it may lead to improvements in their number skills and alertness.
Furthermore, L-theanine can create a savory taste, also known as umami flavor. Research suggests that umami flavors may reduce appetite, which often helps with weight loss.
Furthermore, L-theanine may support the body in fighting off illness. Several studies have suggested that taking L-theanine could boost a person's immune system, making them less likely to get common colds or the flu.
Furthermore, L-theanine may help reduce stress, and a reduction in stress and increased relaxation can lower the heart rate. In turn, this may help lower blood pressure.
Finally it was found that L-theanine may increase the effectiveness of a chemotherapy drug called doxorubicin. It is possible that it makes doxorubicin more effective by increasing the amount of the drug in cancer cells.
Due to the important and very positive of the effects L-theanine has there is always a need to provide formulation comprising L-theanine.
L-theanine has poor compressibility and flowability which causes problems in some formulations.
To deliver L-theanine in tablet format often faces challenges such as capping and low tablet hardness. Many commercially available tablets comprising L-theanine have a low L-theanine content (such as 100 mg per unit or even lower) There are also L-theanine capsules commercially available but the 2-piece capsule shell is often relatively large and not very easy for a consumer to swallow.
The goal of the present invention, was to find a formulation which allows to deliver L-theanine in high dosages (more than 100 mg per unit) and that the formulation is still easy to swallow.
Surprisingly it was found out that it is possible to create a formulation with a high amount of L-theanine in the form of a non-frozen aerated confectionery.
The present invention relates to a non-frozen confectionery (C), consisting of
In the context of the present invention we defined the core as the part of the formulation which can be coated, but the formulation can be a core as such (no coating).
The formulation comprises at least 70 mg L-theanine.
Preferably the L-theanine content is 70 mg to 250 mg.
Therefore, the present invention related to a non-frozen confectionery (C1), which is the non-frozen confectionery (C), wherein the L-theanine of the non-frozen confectionery is at least 70 mg.
Therefore, the present invention related to a non-frozen confectionery (C2), which is the non-frozen confectionery (C) or (C1), wherein the L-theanine of the non-frozen confectionery is 70 mg to 250 mg.
Aerated confectioneries can be classified into two sub-groups, grained and non-grained candies. Grained candies are made from supersaturated sucrose solutions while non-grained candies are made from unsaturated sucrose solutions. The basic composition for marshmallows of all kinds includes water, a disaccharide sugar such as sucrose, a monosaccharide sugar such as dextrose or corn syrup, and a whipping agent such as gelatin. Suitable flavor and coloring materials may also be incorporated into the basic composition. Among the many formulas that are known for marshmallow production are those found in the following: “Candy Making as a Science and as an Art,” by Claude D. Barnett, Don Gussow Publications, Inc., New York, 1960, pp. 99-103; “An Encyclopedia of Candy and Ice Cream Making,” by Simon I. Leon, Chemical Publishing Company, New York, 1969, pp. 294-304, and, “A Textbook on Candy Making,” by Alfred E. Leighton, The Manufacturing Confectioner Publishing Company, Oak Park, III., 1952, pp. 55-58. See-also, for example, U.S. Pat. No. 3,607,309, issued Sep. 21, 1961 to E. S. Olney et al, and U.S. Pat. No. 2,847,311, issued Aug. 12, 1958 to Alexander J. Doumak. Soft marshmallow or “long grain” marshmallow has an elastic and chewy consistency and is the type usually associated with the term “marshmallow”. Sugar ratios are so regulated so that crystallization of the sugars or “graining” does not take place within a reasonable period of time. To accomplish this reduction in the tendency to crystallize, corn syrup of various dextrose equivalents (“DE”) have been employed to inhibit the onset of crystallization.
The non-frozen confectionery according to the present invention consists of a core and an optional coating.
The core of the non-frozen coated confectionery according to the present invention is aerated. A preferred core is kind of a marshmallow (or when there is no coating then the non-frozen confectionery is a marshmallow).
