Fish Protein Powder health benefit, isolates and shakes
Feb 25 2016 by Ray Sahelian, M.D.

Fish Protein Powder is a source of protein as an alternative to soy protein powder, whey protein powder, and other protein powders. Fish Protein Powder can be added to weight loss and protein supplements. It may be a good idea to consume a variety of protein powders rather than a high amount of one or two. The body appreciates being exposed to a variety of nutritional components.

Fish protein powder usually comes from the fillet of fish, hopefully caught in clean waters.

Aliment Pharmacol Ther. 2008. Clinical trial: protective effect of a commercial fish protein hydrolysate against indomethacin (NSAID)-induced small intestinal injury. A partially hydrolysed and dried product of pacific whiting fish is marketed as a health food supplement supporting 'intestinal health'. To examine whether the partially hydrolysed and dried product of pacific whiting fish influenced the small intestinal damaging side effects of the nonsteroidal anti-inflammatory drug, indomethacin. Eight human volunteers completed a double-blind, placebo-controlled, crossover protocol of clinically relevant dose of indomethacin (50 mg t.d.s. p.o. for 5 days) with 7 days of fish hydrolysate or placebo starting 2 days prior to indomethacin. Changes in gut permeability were assessed using 5 h urinary lactulose:rhamnose (L/R) ratios. Fish hydrolysate given alone did not affect permeability. In the main study (n = 8), baseline values were similar for both arms. Administration of indomethacin (+placebo) caused a fivefold rise in L/R ratios, whereas L/R ratios in the same subjects ingesting indomethacin + fish hydrolysate was only 0.59 +/- 0.14 (P < 0.01 vs. indomethacin alone). Dyspeptic symptoms occurred in four of eight subjects taking indomethacin alone, but zero of eight when hydrolysate was co-administered. Natural bioactive products (nutriceuticals), such as fish hydrolysates, may provide a novel approach to the prevention and treatment of NSAID-induced and other gastrointestinal injurious conditions.

J Sci Food Agriculture. 2010. The influence of additives and drying methods on quality attributes of fish protein powder made from saithe (Pollachius virens). Fish protein powder (FPP) is used in the food industry for developing formulated food products. This study investigates the feasibility of increasing the value of saithe (Pollachius virens) by producing a functional FPP. Quality attributes of spray and freeze-dried saithe surimi containing lyoprotectants were studied. A freeze-dried saithe surimi without lyoprotectants was also prepared as a control sample. The amount of protein, moisture, fat and carbohydrate in the FPPs were 745-928, 39-58, 21-32 and 10-151 g kg(-1). Quality attributes of FPPs were influenced by the two drying methods and lyoprotectants. The highest level of lipid oxidation was found in the control and the second highest in the spray-dried FPP. The spray-dried fish protein had the lowest viscosity among all FPPs. Gel-forming ability of samples with lyoprotectants was higher than that of the control. Water-binding capacity, emulsion properties and solubility of the freeze-dried fish protein containing lyoprotectants were significantly higher than spray-dried and control samples. However, functional properties of spray-dried FPP were higher than the control sample. It is feasible to develop value-added FPP from saithe surimi using spray- and freeze-drying processes, but freeze-dried FPP containing lyoprotectant had superior functional properties and stability compared with spray-dried sample. Both products might be used as functional protein ingredients in various food systems.
