[0001] The present disclosure relates to powder compositions, and in particular powder compositions comprising one or more therapeutic ingredients including fiber, and processes of manufacturing the same. The present disclosure further relates to the use of such powder compositions as a prebiotic dietary supplement to maintain and / or improve the gut microbiome and overall gut health of a human.2. BACKGROUND

[0002] The human gut microbiome has a role in overall health in influencing digestion, metabolism, and immune function. Prebiotics are among the various components that support gut health, for example, by fostering growth or activity of beneficial microorganisms such as certain bacteria and fungi while suppressing the growth of pathogenic bacteria. Prebiotics include inulin, fructooligosaccharides (FOS), galactooligosaccharides (GOS), and resistant starch. Despite the recognized benefits of prebiotics, there are several challenges associated with their use. For example, the stability and bioavailability of prebiotics in various dietary supplements remain important factors for effective formulations. There remains a continued need in the art for novel prebiotic formulations that enhance stability, improve bioavailability, and maximize the beneficial effects of prebiotics on the gut microbiota. The present disclosure addresses these and other needs.3. SUMMARY

[0023] The following Examples are intended to illustrate, but not to limit, the subject matter in any manner, shape, or form, either explicitly or implicitly.

[0024] Example 1: Fiber Powder Blend

[0025] The present example was prepared using the formula in Table 1.Table 1. Fiber Powder Formulationknown as Partially hydrolyzed guar gum (PHGG)2: Commercially available as Inavea™ Essential W from the Nexira Corporation3: The actual Fiber mg / Serving is converted from the mg / Serving based on a potency of 85%for Sunfiber® (with 2.8% overage) and 72% for Inavea™

[0026] Processing Directions:1. The Partially Hydrolyzed Guar Gum and Guma Acacia were added to a suitable V-Blender and blended end-over-end for at least 10 minutes.2. The blended mixture is dispensed into barrels.3. From the barrels, the blended mixture is filled into separate packages as sachets, stick packs, or cannisters.

[0027] Example 2: In-Vitro Gastrointestinal Analysis

[0028] Individual fiber components and various ratios of fiber compositions were tested to determine behavior within environments that mimic human gastrointestinal environments. TheseAttorney Docket No. ZAR6104WOPCT1 were analyzed using the Simulator of Human Intestinal Microbial System (SHIME® model) as published in Nutraceuticals 2023, 3, 489-498. https: / / doi.org / 10.3390 / nutraceuticals3040035. The model determined the production of short chain fatty acids and microbial populations.

[0029] Part A: Study Overview. The colonic microbiome of 6 healthy children (3 children between 15 months and 30 months of age and 3 additional healthy children between 31 months and 12 years of age) were simulated using the full SHIME® (proximal and distal colonic bioreactor) and the impact of 3 weeks dosing of the test products were assessed and compared to a negative control. By testing 3 donors of each age group, it was expected to cover the evolution in the children microbiome composition in function of age. Scientific publications have defined three phases in the microbiome development of infants and children: (i) a developmental phase between 3 and 14 months of age (which is not in scope in this Example), (ii) a transitional phase between 15 and 30 months of age, and (iii) a stable phase from 31 months onwards.

[0030] Part B: Methodology and Experimental Setup. The typical reactor setup of the SHIME®, representing the gastrointestinal tract of the adult human, was described by Molly, K., et al. (1993). Development of a 5-step multichamber reactor as a simulation of the human intestinal microbial ecosystem. Applied Microbiology and Biotechnology 39(2):254-258. It consists of a succession of five reactors simulating the different parts of the human gastrointestinal tract. The first two reactors are of the fill-and-draw principle to simulate different steps in food uptake and digestion, with peristaltic pumps adding a defined amount of SHIME® feed (140 mL 3x / day) and pancreatic and bile liquid (60 mL 3x / day), respectively to the stomach (VI) and small intestine (V2) compartment and emptying the respective reactors after specified intervals. The last three compartments simulate the large intestine. These reactors are continuously stirred, they have a constant volume and pH control. Retention time and pH of the different vessels are chosen to resemble in vivo conditions in the different parts of the colon. Upon inoculation with fecal microbiota, these reactors simulate the ascending (V3), transverse (V4) and descending (V5) colon. Inoculum preparation, retention time, pH, temperature settings and reactor feed composition were previously described by Possemiers S. et al. (2004). PCR-DGGE-based quantification of stability of the microbial community in a simulator of the human intestinal microbial ecosystem. FEMS Microbiol Ecol. 49(3):495-507. Upon stabilization of the microbial community in the different regions of the colon, a representative microbial community is established in the threeAttorney Docket No. ZAR6104WOPCT1 colon compartments, which differs both in composition and functionality in the different colon regions.

[0031] A typical long-term SHIME® experiment consists of three distinct phases: (1) A stabilization phase of up to 3 weeks, during which the microbial community differentiates to the specific environmental conditions of the reactors. (2) A control period, during which the baseline properties of the microbial community can be sampled during 6 consecutive weekdays (excluding weekend). (3) The treatment phase, during which a treatment is applied to the microbial communities and its effects are observed. Usually, this phase comprises 3 weeks.

[0032] The normal repeated administration SHIME® setup was adapted to the shortened form, in which no stabilization and control phase are included. Instead, the additional negative control arm was incorporated for each donor to function as a reference. The typical long-term SHIME® setup was therefore adapted to a short-term SHIME® setup, which is divided in the following stages:

[0033] Inoculation period: On day 0, the colon reactors were inoculated with an appropriate fecal sample and were allowed to grow and colonize the reactor. After this overnight incubation, the colon reactors were fed with the basic nutritional matrix for two more days, to support the maximum diversity of the gut microbiota originally present in the fecal inoculum. This also allows the microbial community to differentiate in the different reactors depending on the local environmental conditions.

[0034] Treatment period (TR): During this 3-week period, the SHIME® reactor was operated under nominal conditions and fed 3x / day with the standard SHIME® nutritional medium. In the treatment arms, this diet was supplemented with the test product (i.e., the formulation in Example 1, Table 1). Samples were taken from the colon reactors throughout this period to investigate the specific effect on the resident microbial community composition and activity. Other fiber types were tested including Pure Gum Acacia; PHGG; PHGG:Gum Acacia (50:50); and Gum Acacia (Alternate). The Pure Gum Acacia and PHGG were the same ingredients utilized in Example 1, Table 1 and for the PHGG: Gum Acacia (50:50) product. An alternate Gum Acacia, Pre-Hydrated® Gum Arabic FT (ARAB PH-FT) commercially available from Ingredion was also tested.

[0035] During each period, the model was fed 3x / day with the SHIME® nutritional medium (17.2 g / L PDNM005 for toddlers and 15.6 g / L PDNM001B for young children; set at pH = 3.0 (toddlers) or pH = 2.0 (young children)) and pancreatic juice (NaHCO3, oxgall and pancreatin).Attorney Docket No. ZAR6104WOPCT1

[0036] The three feeding cycles of the SHIME® for this Example started at 9h, 17h and Ih (SHIME® time). The feed in each cycle entered in the colon 3h after the start of the cycle (so at 12h, 20h and 4h SHIME® time).

[0037] Following samples were collected from the SHIME® experiment:1. Overall fermentative activity: a. Acid / base consumption2. Microbial Community Activity a. Short Chain Fatty Acids (SCFA): Acetate, Butyrate and Propionate b. Lactate c. Ammonium3. Microbial Community Composition a. llumina 16S rRNA sequencing b. Quantification of total bacterial cells by flow cytometry

[0038] Part C: Results. The results of the study are provided in Table 2.Table 2. Study ResultsAttorney Docket No. ZAR6104WOPCT11 : Commercially available as Inavea™ from the Nexira Corporation2: Partially Hydrolyzed Guar Gum: Commercially available as Sunfiber® from the Taiyo International Corporation3: Commercially available as Pre-Hydrated® Gum Arabic FT (ARAB PH-FT) from Ingredion Corporation

[0039] Results Summary: Fermentative activity can be categorized into saccharolytic fermentation and proteolytic fermentation types. Saccharolytic fermentation includes the production of short chain fatty acids such as acetate, propionate and butyrate. Saccharolytic fermentation also includes the production of lactate. Proteolytic fermentation includes the production of branched chain fatty acids and ammonium.
