Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0014] These and other features, aspects, and advantages of the present invention will become better understood with reference to the following description, appended claims, and accompanying drawings where:

[0015] FIG. 1 is a flow diagram.

[0016] FIG. 2 is a block diagram.

DETAILED DESCRIPTION

[0017] The subject innovation is now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It may be evident, however, that the present invention may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate describing the present invention.

[0018] The present invention addresses how to make limited ingredient, nutritious human food or animal feed without adding low nutrition binders, and using high energy (e.g., steam), high heat, high pressure.

[0019] Spirulina is commonly referred to as an edible blue-green algae but more correctly it is a cyanobacteria. It is also considered an aquatic micro-organism because it is grown in mostly brackish water. Spirulina is considered a Superfood because it is high in protein (e.g., 55-70%), nutrient dense, highly digestible with anti-inflammatory benefits. Both NASA and World Health Organization consider Spirulina to be among the healthiest known organisms. Spirulina is a whole food and complete protein. Whole food refers to a plant food that is unprocessed and unrefined or that which has had minimum processing and/or refining. Complete protein is a source of protein that contains all nine of the essential amino acids as well as non-essential amino acids. This is not common among plants but Spirulina meets this definition.

[0020] Spirulina consists of approximately 55-70% protein, 15-28% carbohydrates, 0.5-8% lipids and moisture. Spirulina has no root system and is grown in water, not hydroponically or in soil. It has soft cell walls made of complex sugars and protein that can breakdown quickly with low heat or by human/animal digestive systems.

[0021] The present invention describes how to grow and harvest edible, nutritious living cyanobacteria (e.g., spirulina). When this living cyanobacteria is harvested the excess water is drained leaving a pudding-like consistency. Other wet and/or dry ingredients are mixed with the wet living cyanobacteria at ambient temperature and at low speeds to make a batter. The batter can hand formed or pressed flat at low pressure. The formed batter is then placed inside of a dehydrator, which is used for drying. A dehydrator refers to a device that removes moisture from food to aid in its preservation. The dehydrator is set at a low drying temperature typically between 110 F.-125 F. The industry standard for cyanobacteria drying is a spray-drying process, which uses higher temperature and pressure and can negatively affect amino acids and nutrients.

[0022] When the formed batter is drying at low heat, the cell walls start to breakdown releasing the natural carbohydrates. These carbohydrates, made of simple sugars and proteins, leach out from the live cyanobacteria onto the other ingredients. When the product starts to cool the sugars have a sticky consistency and upon full cooling the live cyanobacteria carbohydrates act as a binder.

[0023] The present invention enables the production of limited ingredients food/feed products when one combines fresh, harvested wet living cyanobacteria (high protein & nutrient dense) with other wet and dry ingredients, mixed and dried under low temperatures. There is no need for high energy, high temperature, high pressure, which can damage nutrients and amino acids.

[0024] Turning now to FIG. 1, a method 100 of producing live cyanobacteria as a binding agent in human and animal foods includes growing (110) cyanobacteria (e.g., spirulina) in closed bio-reactors.

[0025] Grown living cyanobacteria is harvested (120) in a filtration system, creating a pudding-like consistency in which the cyanobacteria is still alive.

[0026] The harvested living cyanobacteria is mixed (130) with enough additional dry & wet ingredients to create a batter. The dry and wet ingredients may be feed ingredients or food ingredients. Example feed ingredients include, wet ingredients such as vegetable or fish oils and/or water, and dry ingredients such as grain meals, fish meal, shrimp meal, kelp (seaweed) and protein powders. Example food ingredients include wet ingredients such as edible vegetable oils and/or water, and dry ingredients such as nuts, seeds, dried fruit, cinnamon and seasonings.

[0027] The batter consisting of live cyanobacteria is formed (140) into a desired shape and dehydrated using low heat, such as heat between 110 F. and 125 F. The low heat causes natural carbohydrates (starches) to leach out of cells onto other ingredients. The batter may be formed (140) by hand or automatically, such as in a food processor.

[0028] The dehydrated batter is dried (150) for a specified amount of time. For example, depending on ingredients, drying time may be three to eight hours, allowed to cool (160) in which the starches act as a natural binder in the finished product.

[0029] As shown in FIG. 2, an exemplary system 200 producing live cyanobacteria as a binding agent in human and animal foods include a closed bio-reactor 210 configured to grow live cyanobacteria and a filtration device 220 configured to harvest the grown living cyanobacteria to create a pudding-like consistency.

[0030] The system 200 includes a mixing device 230 configured to mix the pudding-like living cyanobacteria with dry and wet ingredients to create a batter and a shaping device 240 configured to form the batter into a desired shape.

[0031] The system 200 includes a dehydration device 250 configured to dehydrate the shaped batter using low heat.

[0032] The system 200 includes a drying device 260, the drying device 260 configured to dry the dehydrated batter for a pre-set time and a cooling device 270, the cooling device 270 configured to cool the dried dehydrated batter. In one embodiment, the drying device 206 and cooling device 27 are implemented as a single device configured to dry and cool.

[0033] It would be appreciated by those skilled in the art that various changes and modifications can be made to the illustrated embodiments without departing from the spirit of the present invention. All such modifications and changes are intended to be within the scope of the present invention except as limited by the scope of the appended claims.
