Abstract: The present invention provides a system and method for extracting starch from green bananas. The system includes: a pretreatment module configured to grind and homogenize the green bananas so as to form green banana slurry; an extraction module configured to receive the green banana slurry, and configured to add an extraction solvent to the green banana slurry to generate an extracted mixture of green banana starch; a separation module, wherein the extracted mixture of green banana starch is held still in the separation module, so green banana starch precipitates and green banana suspensions are precipitated and separated; a first rinsing module configured to rinse green banana starch precipitates to remove any impurities except for the starch therein, thereby forming a banana starch cream; and, a dehydration module configured to remove water from the banana starch cream to form banana starch.

Abstract: An assaying device for determining the activity value of Nattokinase solution includes a container having a testing solution therein. Because the testing solution can react with a Nattokinase solution and the reacted testing solution has a different color from the original testing solution, when the testing solution contacts a Nattokinase solution, the reaction occurs along the container. By measuring the length of the reacted testing solution, the activity value of the Nattokinase solution can be easily and quickly obtained.

Abstract: This present invention is related to an algae fluorescence protein dry powder structure and the manufacturing method thereof. The algae fluorescence protein dry powder structure includes a substrate and a mixture layer, which is coated around the substrate. The mixture layer consists of polysaccharide and algae fluorescence protein, wherein the weight proportion of the polysaccharide should be smaller than 10%. The method will dry the algae fluorescence protein and then protect the structure of them from damage.
