The View Inside Our Process

Reconsider the use of the terms “All Natural” by other supplement manufacturers as you review the process outlined below that is employed by African Wild Naturals to bring you ZuluTEST (with bulbine natalensis). There is no heat, chemical or human manipulation of the original freeze dried plant bioactive materials that come straight from the wilds of Africa. The potency and efficacy of these botanical supplements are without comparison. In addition, all manufacturing (veggie encapsulation of the freeze dried extract, bottling, labeling) occurs in an FDA registered food facility (Food Facility Registration Number:17423811494) under GMP standards with a Pro Cert, SA validation for ISO 22000 production standards.

From Harvesting to Freeze Dried Extract

Live plant material is inspected by in-house horticulturist to determine species correctness. Site for wild harvesting is pre-inspected in advance of the event to determine that the species is botanically correct as per the voucher specimen reference.

Reference material from the wild harvesting site is inspected to check moisture and maturity of tubers. Moisture levels are determined by drying 500g fresh tuber on gas flatbed dryers over 8 hours. Wet:Dry moisture ratio should comply to in-house standards. Tubers should comply with minimum size requirements, be free of rot or excess foreign matter.

Ensure that the harvesters are skilled in identifying the plants as per in-house quality requirements for raw material: species correctness, tuber size, tuber health. Pre-selected sites are then foraged by collectors. Live plants are uprooted, excess soil and foreign matter re-moved and placed in agricultural sacks. Ensure excess leaves removed and there is minimal foreign matter.

Reference material from the wild harvesting site is randomly selected from raw material bags and inspected to check quality criteria. Representative samples of wild harvested material are selected from random bags across the sample group. Material is re-checked for compliance with quality controls criteria.

Fresh wild harvested material is unpacked and moved into plastic crates for washing and rinsing with cold water. Checks for: presence of rotting, dead, dry plant matter, check for species correctness, check for foreign matter (wire, wood, stones, mud, plastic etc). Irregularities are removed and noted by weight and photographed for record keeping. Foreign matter is removed and safely discarded. QC manager must take notes of any discrepancies. Material that has passed initial QC assessment is now submitted to receiving area. Crates are sprayed with cold water and checked during the rinse to remove excess foreign matter (high pressure hose). QC manager must determine if steam sterilization is necessary. Washed material must be inspected before moving to processing area for slicing prior to freeze drying.

Actives found within the cellular structures of organic materials have for a long while been sought as an alternative and more natural treatment compared to synthetic and chemical cures. The typical method of extraction uses chemical processes to rupture the cell walls and dissolve active ingredients into a carrier such as maltodextrin. The technique used with ultrasonic extraction is to bombard the cellular matter with high frequency sound waves which rupture the cell walls of the plant material in a non-thermal, non-chemical manner. This method is said to disrupt 99% of the cell structures so there is no waste product. Additionally, by omitting the use of chemical solvents there is limited reduction of the integrity of the biologically active profile of the plant matter and therefore possibly better assimilation in the human body.

The process of freeze-drying is the most advanced form of preservation available to the food industry today. By a combination of vacuum and ultra-cold conditions, freeze-drying removes almost 100% of the water inside the plant matter and therefore leaves no atmosphere for bacteria to grow. This process can preserve plant material in almost perfect state of freshness for 5 years, provided it is stored correctly. Research suggests that freeze-drying is the most effective way to preserve active ingredients in plant material for medicinal and nutritional use and this is why we have applied the process to our herbal extracts: it ensures their long term stability, improved shelf life, better preservation of the active ingredients and retains a very high level of biological activity from the whole content of the herb (enzymes and sensitive nutrients are often denatured by chemical extraction).
