DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS [0047] In the present embodiment, a gas plasma treating is utilized in a method and apparatus of treating a vitamin or mineral supplement, such as a protein powder. The surface treatment and/or etching apparatus as illustrated in Figures 1-7 is adapted for use to treat a protein powder with plasma surface etching. Gas plasma allows for molecular engineering of materials to impart unique characteristics and surface properties without

WO 2018/236574

PCT/US2018/036043 affecting the bulk properties of the whole material. The use of plasma in the present invention may change the surface characteristics such as changes in biocompatibility, surface energy, morphology, texture, and absorption.

[0048] In the present embodiment, application of plasma to powder, specifically protein powder supplements, significantly increases absorption and digestibility factors (increase solubility by 71%, hydrophobicity by 27% and surface Area by 26%). Protease (which breaks down protein and allows your body to use it) such as Pepsin, Chymotrypsin, Serine and Elastase are most effective on hydrophobic amino acids. When the current plasma treating process is used with protein powder, hydrophobicity is increased by up to 27%. Supplementation allows the body to receive vitamins and minerals that are either lacking through diet or needed in excess of ordinary diet. By way of example, strength athletes frequently use protein powder which can help prepare damaged muscles that occur with weightlifting as well as the recovery period. In the present embodiment, this apparatus is used for plasma treating protein powders. However, this apparatus can be used with plasma treating any powder, granular or powder-like material.

[0049] In one embodiment, the plasma used is atmospheric pressure plasma. Atmospheric pressure plasma is a plasma which the pressure approximately matches that of the surrounding atmosphere. Atmospheric pressure plasma allows for a variety of characteristics including activation and etching. In other embodiments of the present invention, various other types of plasma may also be used such as corona treatment, corona discharge, flame plasma, chemical plasma, dielectric-barrier discharge, or partial discharge. The present embodiment utilizes a plasma plume incorporated within the apparatus.

[0050] The apparatus of the present invention is depicted in Figures 1-7 in accordance with one or more embodiments. The plasma generator 100 includes a plasma generator

WO 2018/236574

PCT/US2018/036043 head 101. The plasma generator head 101 includes the plume producer 111 to produce a plume required for atmospheric pressure plasma application. The apparatus 100 further includes a mounting bracket 102 having mounting apertures 112. The mounting bracket 102 allows the apparatus to be mounted to a flat surface allowing for an upright configuration during plasma treatment. The upright configuration allows for utilizing gravity as the powder or other supplement flows through the main powder inlet tube 104. The powder inlet tube includes apertures 114, 115 leading to a central bore extending through the powder inlet tube 104. Alternatively, the bracket 102 can be angled.

[0051] In one embodiment, protein powder (or any other powder or granule) is introduced into the system at an angle. By controlling the angle of the entire assembly, the speed of the powder flow can also be controlled. Accordingly, the main mounting bracket 102 is adjustable to allow adjustment of the angle of the powder inlet tube 104.

[0052] The plasma/air orifice 103 provides for a rotating head which aerates the powder with compressed air during and before exposure to the plasma plume. The plasma/air orifice 103 allows for a larger area of the protein powder to be exposed during plasma treatment. The plasma/air orifice 103 includes an outer surface 117 have connection portions 113 to connect to the remainder of the apparatus.

[0053] The plasma reaction chamber 105 is provided at a lower end of the apparatus 100. The main reaction chamber 105 is where the protein powder from the inlet tube 104 connects with the plasma plume in the plasma generator head 101. A secondary airflow control 108 is further provided in fluid communication with the plasma generator head 101. The secondary airflow control 108 prevents powder from backing up in the plasma generator head. The secondary airflow control 108 puffs and aerates the powder during the plasma treating process. Furthermore, the secondary airflow control increases exposure of

WO 2018/236574

PCT/US2018/036043 the protein powder to the plasma thus increasing the quality of the finished protein powder. The control 108 includes a connector 158 having a adjuster 158, a connector 154 and a data output 152.

[0054] An adjustable cutoff control valve 107 is also provided. The control valve 107 includes a “flapper” which prevents fast flow of air through the system. The valve includes an inlet 127 and corresponding connection portion 119.

[0055] Furthermore, a main airflow control 109 is provided to control the flow of air and protein powder through the system. It is crucially important to provide a constant flow of steady air while not having the air move too fast through the system.

[0056] The above apparatus for treating supplement powder (by surface treating and/or etching) may also be provided to other supplements in various forms (powder, pills, tablets, etc.) to increase absorption characteristics.

[0057] In yet another embodiment of the present invention, gas plasma treating is utilized in a method and apparatus of treating a vitamin or mineral supplement. The surface treatment and/or etching may also be utilized in the present embodiment. Gas plasma allows for molecular engineering of materials to impart unique characteristics and surface properties without affecting the bulk properties of the whole material. The use of plasma in the present invention may change the surface characteristics such as changes in biocompatibility, surface energy, morphology, texture and absorption. Supplementation allows the body to receive vitamins and minerals that are either lacking through diet or needed in excess of an ordinary diet. By way of example, strength athletes frequently use protein powder which can help repair damage to muscles that can occur with weight lifting as well as in the recovery period.

WO 2018/236574

PCT/US2018/036043 [0058] Plasma treating a supplement (by surface treating and/or etching) aids and expedites the digestion process by increasing bioavailability and absorption. It is estimated that one half of the US population produces insufficient stomach acid which diminishes the ability to absorb nutrients from food. Referring now to Figure 5, an aerated method and apparatus 200 for exposing/treating supplement power to a plasma field is disclosed in the following:

a. Adding powder into a swirl cyclone chamber manually or via vacuum suction (through inlet 206);

b. Swirling the powder in the chambers 201A, 201B continuously for a predetermined amount of time to create a vortex 250 in the powder 219;

c. Injecting plasma (at reference numerals 205, 208) into the vortex of the swirling powder and/or injecting the plasma into the swirl stream or plasma field 250;

d. Optionally connecting multiple chambers for treatment with other gasses. Connecting these chambers in series (open air, argon, neon, inert gas.. .etc.) (through the inlets 206, 222 and tube 204); and

e. Sealing powder in individual pouches, vacuum pouches, capsules or other storage containers in an effort to reduce contamination.

[0059] Figures 6 and 7 illustrate another embodiment and plan view of a plasma treating apparatus and corresponding method. The apparatus 300 includes a hopper 302 having a turning mechanism 304 for pushing the powder through the system. The system

WO 2018/236574

PCT/US2018/036043 and method portion 308 includes a series of steps and method for plasma treating the powder or granules A-G.

[0060] Step A includes the gravity fed and air regulated flow rate. Current plasma reactor designs require large cycle times (upwards of 40 minutes) and depending on the underlying substrate may need to operate in a vacuum or with a non-atmospheric gas such as helium or argon. The present application discloses a novel reactor that allows a powder to be fed into the plasma chamber by gravity which allow for a faster cycle time while maintaining a controlled exposure and flow rate. For further control, an auger can be used to increase the plasma exposure time or conversely air pressure can be increased to lower the plasma exposure time. The unique reactor design also allows the air pressure in the reaction chamber to be independently controlled and maintained to impart unique characteristics on the underlying powder such as increasing the inherent surface area.

[0061] Step B includes the ability for vibration capability and a vibrator. When processing large volumes of powder, a common occurrence with a plasma reactor is jams or fine powders working their way into moving parts. The reactor allows for regular mechanical vibrations which prevent powder buildup and damage to moving parts. Vibration is particularly effective with smaller powder particles.

[0062] Step C relates to air pulsing and an air pulsor. Similar to the vibration capability, the reactor has unique air injectors mounted around the entry opening. While these can be used to independently increase air pressure in the reactor or increase the flow rate of the powder, it can also be used to prevent powder buildup. Vibration is effective against smaller powdered particles and air pulsing prevents smaller particles from building up in the reaction chamber. Buildup is important for machine runtime as well as to prevent

WO 2018/236574

PCT/US2018/036043 powder from being overexposed to plasma which could destroy it or give it characteristics outside the engineered tolerances.

[0063] Step D is the heating coil and/or heatsink. The reactor can be fitted with heating coils around the reaction chamber to increase the overall plasma reaction temperature. This can impart unique characteristics such as breaking the hydrogen bonds in a protein peptide to alter the tertiary structure and denature the peptide. Conversely, a heat sink can be fitted with either passive or active cooling (depending on plasma strength) to maintain a reaction at ambient air temperature.

[0064] Step E is the humidity and/or water injector. The plasma reactor can take advantage of natural humidity to change the reaction characteristics. This has been show to incite hydrolysis in protein peptides and the degree of hydrolysis can be controlled by relative humidity or even injection water directly into the reaction when a high degree of hydrolysis is required. Conversely, an air dryer can be fitted to feed the reaction when no hydrolysis is required.

[0065] Step F is the magnetic and/or electromagnetic plasma “lens”. The use of magnetic or electromagnetic fields to contain plasma is well studied and even demonstrated in reactor designs such as a Tokamak or Stellarator reactor in fusion research. Similarly, the reactor design allows the use of a spherical magnetic field to help concentrate the plasma and mitigate plasma loss. This increases the efficiency and exposure time of the plasma without increasing the energy required to generate the plasma field.

[0066] Step G is the ultraviolet and/or pulsed light. Exposure to ultraviolet radiation or high energy pulsed light has been used for sterilization or to change the surface characteristics of a substrate. The reactor allows for both ultraviolet and pulsed light

WO 2018/236574

PCT/US2018/036043 exposure during the plasma reaction or optionally this can be utilized prior or directly after plasma exposure. Currently no commercial system allows for both plasma exposure combined with PL or UV exposure inline (or simultaneously).

[0067] The treated powder and/or granules are collected in the collection tank 160 (as illustrated in Figure 1). The treated powder and/or granules are then transferred to storage or other packaging.

[0068] It should be noted that the steps A-G and corresponding apparatus parts can be used in the order as described above or in any other suitable order.

[0069] The above method and apparatus for treating supplement powder (by surface treating and/or etching) may also be or provided to other supplements in various forms (powder, pill, tablet...etc.) to increase absorption characteristics.

[0070] Several of the parameters as described above may be varied to obtain a desired protein structure for the treated supplement powder. For example, the exposure time, plasma strength, plasma frequency, temperature and humidity or presence of water may all be adjusted to have a desired structural change to a protein such changes to the secondary and tertiary structures of the protein.

[0071] Some of these parameters and their interactions have a correlation with each other. For example, operating the apparatus as described above having a plasma power at 500-watts and expose for 1 second would result in a similar modified protein as operating with the plasma at 1000-watts for 0.5 of a second. However, in practice, there can be benefits to a longer exposure time allowing the plasma to permeate a very large powder granule. Other parameters such as the humidity display a more linear relationship. With no humidity, the modified protein has a very low or non-existent DH (degree of hydrolysis, or

WO 2018/236574

PCT/US2018/036043 breaking down the amino chain length) whereas an increase in humidity results in an increased DH.

[0072] In one aspect, the process utilized does not thermally denature the protein. The process may include controlling the heat of the reaction or pre-warming the protein before it 5 enters the tube to speed up the plasma reaction. For example, the process may include a 70 degree, 500-watt reaction to obtain a desired modified protein structure. Alternatively, one may pre-heat the processed powder to 80 degrees and thereafter use a 400-watt reaction to obtain a similar change to the protein structure and result in a faster throughput of the process. In one aspect, the process may include a power from 250 to 10,000W at a 10 temperature of from 50 to 250 F at a rate of from 1/10 to 10 Ibs/s.

[0073] Examples [0074] Whey protein powders including WPI and WPC were processed in the apparatus as described above using various parameters as will be described below.

[0075] Referring to Figure 8, there is shown a plot of the hydrophobicity by 15 fluorescence Intensity as measured by probe Spectrofluorometry of various samples using the process as described above. The parameters for the various samples are displayed in Table A below. The change in hydrophobicity indicates a change in the protein structure in comparison to an untreated protein.

The x-axis indicates the amount of protein in, and the y-axis displays Maximum solubility percentage. A straight line going from 0 to 100 on both axes would indicate 100% solubility. As can be

WO 2018/236574

PCT/US2018/036043 seen, the treated protein sample over performs at low levels, but also has a much higher peak. The water is able to take up more treated protein before the protein peaks.

[0090] Referring to Figure 18, the water can dissolve over 150% more treated protein in comparison to the un-treated, sample. The treated protein is completely dissolved, and not particulate or clumped to any degree indicating an increased amount of bioavailability and access for digestive enzymes.

Dual energy x-ray absorptiometry was utilized to measure test subjects at the start and conclusion of the study.

[0093] The treated protein was a WPI protein that was processed at a temperature of from 80-100 degrees F with a plasma power of 750-1000W at a through put of 1 Ib/s. As can be seen in Figure 23, the treated protein includes a significantly higher surface area in

WO 2018/236574

PCT/US2018/036043 comparison to the un-treated sample indicating a higher bioavailability. As shown in Figures 24-25, subjects taking the treated protein experienced a clinically and statistically significant 204% increase in lean muscle mass and an 18% increase in fat loss in comparison to the uprocessed whey protein.

[0094] Referring to Figures 26-30 there are shown plots detailing the digestibility, mixability and muscle recovery for processed and un-processed samples as described above. Subjects taking the treated protein experienced a clinically and statistically significant 62.50% reduction in gastrointestinal distress, 46.05% improvement in stomach comfort, 30.26% improvement in mixability and a 33% increase in muscle recovery time when compared to the un-processed whey protein. Referring to Figures 30 and 31, there are shown plots detailing the strength characteristics of a subject taking the treated and un-treated proteins. As can be seen in the plots, subjects taking the treated protein had a clinically and statistically significant 172.64% increase in bench press strength and a 170.85% increase in squat strength in comparison to an untreated protein.

[0095] Another study was performed with an older population of adults to determine the effects of the treated proteins ingested by humans. A total of 19 individuals were randomized to one of two groups in a 12 week study in which 15 completed the study. Seven individuals were in an experimental group receiving a treated protein and eight individuals were in a control group. A graphical representation of the study parameters are displayed in Figure 32. The treated protein was a WPI protein that was processed at a temperature of from 80-100 degrees F with a plasma power of 750-1000W at a through put of 1 Ib/s. The untreated or control group was given a WPI protein.

Graphical representations of the percentage of proteins consumed for the study and the Resting Metabolic Rate (RMR) are provided for the experimental and control groups in Figures 35 and 36 respectively. As be seen from the figures, the experimental group showed an increase in the amount of proteins consumed in comparison to the control group. Additionally, the experimental group showed a much larger increase in RMR from the start of the study to week 12 in comparison to the control group.

[0097] In another study, 32 resistance-trained males (22.2±4.3years; 177.3+7.8cm; 77.6+12.6 kg) participated in this randomized, double-blinded investigation. Participants were matched according to FFM and randomized to the Standard WPI (n=18) or the Novel WPI (n=14). The Standard WPI group was provided with 27g of WPI per serving and the Treated WPI group was given a reduced volume of WPI (20g of uniquely treated WPI+7g maltodextrin to match the volume of the Standard WPI serving size). Both protein supplements were taken daily, including immediately after each training session (4x/week). The treated protein was a WPI protein that was processed at a temperature of from 80-100 degrees F with a plasma power of 750-1000W at a through put of 1 Ib/s. Both groups performed the same training program, and maintained a protein intake of 1.5-2.5g/kg/d to facilitate recovery from and adaptation to training. At baseline and following 8-week training program, participants were assessed for maximal strength on the back squat, bench press, and deadlift. The program consisted of two lower-body and two upper-body workouts/week for an 8-week period.

PCT/US2018/036043 [0098] Data were analyzed via a 2-factor [2x2] between-subjects repeated measures ANOVA and pre to post changes within each group were analyzed by a paired-samples ttest. The alpha criterion for significance set at 0.05.

[0099] No differences existed between the two groups for strength measures at baseline. The repeated measures ANOVA revealed a main effect for time for the back squat (pO.001), bench press (pO.001), and deadlift (pO.001) exercises, but no group x time interactions were observed for absolute or relative strength between groups.

[00100] Specifically, back squat increased from 131.2±25.5kg to 144.8±25.1kg (improvement of 10.4%) and from 131.6±37.6kg to 145.5±35.4kg (improvement of 10.6%); bench press increased from 100.3±19.0kg to 108.0±19.5kg (improvement of 7.7%) and from 96.0±19.9kg to 100.9±20.2kg (improvement of 5.1%); deadlift increased from 151.0±33.3kg to 162.0±31.1kg (improvement of 7.3%) and from 149.6±31.9kg to 158.7±35.3kg (improvement of 6.1%) in the Standard WPI and Treated WPI groups, respectively. Data regarding the study is displayed in Figure 37.

[00101] In resistance-trained males, using a reduced amount (25% less WPI) of treated WPI as a post-workout protein supplement elicits the same increases in strength as a higherprotein dosed, standard WPI supplement.

[00102] Additionally, the same study participants were also accessed for body composition. 32 resistance-trained males (22.2±4.3years; 177.3±7.8cm; 77.6±12.6kg) participated in this randomized, double-blinded investigation. Participants were matched according to fat-free mass (FFM) and randomized to the Standard WPI (n=18) or the Novel WPI (n=14). The Standard WPI group was provided with 27g of WPI per serving and the

WO 2018/236574

PCT/US2018/036043 treated WPI group was given a reduced volume of WPI (20g of uniquely processed WPI+7g maltodextrin to match the volume of the Standard WPI serving size) immediately after each resistance training session (4x/week). At baseline and following 8-weeks of training, participants were assessed for body composition (FFM, dry lean mass [DLM], fat mass [FM], and bodyfat percentage [BF%]). The resistance-training program consisted of two lower-body and two upper-body workouts/week for 8 weeks. Data were analyzed via a 2factor [2x2] between-subjects repeated measures ANOVA and pre to post changes within each group were analyzed by a paired-samples t-test.

[00103] No differences existed between the two groups for body composition measures at baseline. The repeated measures ANOVA revealed a main effect for time for FFM (p<0.001) and DLM (p=0.05), but no group x time interactions. Specifically, FFM increased from 68.8±9.3kg to 70.0±9.4kg and from 67.1±9.0kg to 67.8±9.7kg; DLM increased from 19.6±3.7kg to 20.2±3.5kg and from 19.3±3.6kg to 20.1±5.2kg in the Standard WPI and treated WPI groups, respectively. The paired samples t-test revealed a significant increase in FFM over time in the Standard WPI group (p=0.001) and a trend for significance in the treated WPI group (p=0.082). However, when body water was accounted for (DLM), neither group significantly increased DLM over time (Standard WPI: p=0.164; Novel WPI: p=0.185). There were no main effects for time nor a group x time interaction for FM and BF% (p>0.05). Data regarding the study is displayed in Figure 38.

[00104] In resistance-trained males, using a reduced amount (25% less WPI) of treated processed WPI as a post-workout protein supplement elicits changes in body composition similar to using a higher-protein dosed, standard WPI supplement.
