Studies On The Dietary Fiber Of Kelp

The residue of brown seaweed industry would be used as a exploiture potential resource of dietary fiber,even though it was a industrial waste recently. Dietary fiber from kelp ( DFK ) is the waste-residue produced in the process of brown seaweed. It also a exploiture potential resource of ddietary fiber . But at present it shouldn't exert its functions and advantages.The research of dietary fiber have became the researchful hotspot for the raw material of functional foods. In this paper, the actuality and the using value of DFK were discussed. The different effects about treated by acid and alkali of DFK and to choose the best suitable technological parameters were investigated. The research mentioned above provided scientific basis for applying to food industry:1. Two kinds of kelps from Shandong and fujian were compared and the basic elements and the level of amino acids were mensured. It was showed DFK has the favorable nutrition . It can be the complementarity of the dietary fiber and amino acids.2. The dehydrating rate and configuration of DFK were compared and the effects for the guide lines of different breeds of kelps were studied.3. The rate of eliminate of Pb> Cu> Cd and Mn were used as the guidelines and the consistency and treating time of citric acid were used as the restricted factors. Using quadratic-regression-cross design method, we established the mathematical models to study their effects. After studying , we confirmed the best technological parameters were that the concentration of citric acid is 18.7% and the temperature is 83℃ for waste-residue of kelp (WRK) from fujian , the concentration of citric acid is 15.5% and the temperature is 4℃ for WRK from Shandong.4.The two kinds powder of waste-residue of kelp (WRK) were compared at a few physical aspects including loose density, compact density, the rate of expanding, the power of expanding, the power of holding-water, the angle of repose and the angle of moving. It showed the WRK containing about 36% dietary fiber have good the power of expanding and the power of holding-water.5.The power of expanding and holding-water and the rate of production were used as the guidelines and the concertration of NaaCOs, the temperature and the time were used as the effect factors-Using L9(34), the best technological parameters were 20% Na2CO3, 70℃ and treating 90 minutes6.The cayenne sauce, the ketchup,the WRK and the sugar were studying during the compound sauce of dietary fiber from kelp which using Lie (44). After the assess of organ, the best suitable mix was: the cayenne sauce 25.1%, the ketchup 30%, the WRK 12.9%, the sugar 8.6%oThe study provided the necessary scientific evidences for the recycling treatmentof the waste-residue of kelp. Discussing the foregroundof exploitation, we think the waste-residue of kelp is a good resource of dietary fiber.
