Background Fish byproducts are commonly recognized as low-value resources. In order to increase the value, fish byproducts need to be converted into new products with high functionality such as fish protein hydrolysate (FPH). In this study, FPH manufactured from parrotfish (Chlorurus sordidus) heads using different pH, time and sample ratio was investigated. Methods Hydrolysis reactions were conducted under different pHs (5, 7, and 9) and over different durations (12 and 24 h). Control treatment (without pH adjustment (pH 6.4)) and 0 h hydrolsisis duration were applied. Hydrolysates were characterized with respect to proximate composition, amino acid profile, and molecular weight distribution. The antioxidant activity of the hydrolysate was also observed. Results The pH and duration of hydrolysis significantly affected (p < 0.05) the characteristics of FPH. The highest yield of hydrolysate (49.04 ± 0.90%), with a degree of hydrolysis of 30.65 ± 1.82%, was obtained at pH 9 after 24 h incubation. In addition, the FPH had high antioxidant activity (58.20 ± 0.55%), with a high level of essential amino acids. Results suggested that FPH produced using endogenous enzymes represents a promising additive for food and industrial applications.

Abstract Snakehead fish (Channa striata) in South Sumatra, Indonesia has been widely used as a raw material in the processing of typical Palembang food industry, namely pempek, kemplang, and kerupuk. During its processing, not all parts of the fish can be utilized. In general, only 40% of the fish is used for consumption and 60% is wasted as by-products. One of the by-product produced during processing is viscera which can still be used as value-added products. One alternative is to use viscera as raw material in the production of fish protein hydrolysate (FPH) which is well known to have functional properties such as antioxidant, antibacterial, antihypertensive, and anticancer. This research was aim to determine the antioxidant activity of FPH made from snakehead fish viscera as a source of natural antioxidants. The research was conducted by papain treatments with the concentration of enzymes used were 1%, 2% and 3%. Evaluation of the hydrolysis process was done by measure the soluble protein and DH (degree of hydrolysis) while antioxidant activity was carried out by DPPH (1,1-diphenyl-2-picrylhydrazyl) and ABTS (2,2-Azinobis 3-ethyl benzothiazoline6-sulfonic acid) assay. DH of fish protein hydrolysate was found to be 68.79%, 77.06% and 72.63%, respectively while protein solubility gave values of 5.69%, 6.15% and 6.56% respectively. The highest antioxidant activity was attained at enzyme concentration of 3% with DPPH (1,1-diphenyl-2-picrylhydrazyl) and ABTS (2,2-Azinobis 3-ethyl benzothiazoline 6-sulphonic acid) value were 37.26% and 58.58% respectively.

Background:  Wheatgrass (Triticum aestivum L.) is worldwide consumed and has been used for health benefit or functional or nutraceutical food while ricegrass (Oryza sativa L.) is still not well documented, which is also in the grass family (Poaceae) as wheatgrass and it is also produced with aged around 8-10 d which similar to wheatgrass production. Moreover, priming is a process for enhancing seed vigour properties and improving bioactive compounds. Utilization of fish protein hydrolysate (FPH) for liquid fertilizer is more interesting in order to increasing of nutritional value and bioactive compounds as well as antioxidant activity of many plants.Objective: To investigate the nutritional value and bioactivity of ricegrass as affected of priming process with fish protein hydrolysate.Methods: The Chainat 1 rice seeds were soaked with FPH at 0, 5, 10, 15 and 20 ppm at a ratio of rice seed to FPH as 1:5 and grown for 7 d, thereafter, the ricegrass were determined seed vigour properties, nutritional value and bioactive compounds such as chlorophyll, carotenoids, total phenolic and phytic acid. The ricegrass was extracted with water at a ratio 1:2 (ricegrass : water), then homogenized and centrifuged at 10000xg for 20 min. The thereafter, the supernatant was brought to freeze dry. The freeze-dried powder was dissolved in distilled water and brought to measure total phenolic content by Folin-Ciocalteu method. Antioxidant activities were determined by 3 assays as ferric reducing antioxidant power (FRAP), 2,2-diphenyl-1-picryl hydrazyl radical (DPPH) and 2,2'-azino-bis-3-ethylbenzthiazoline-6-sulphonic acid radical (ABTS) methodsResults: The results showed that FPH at 10 ppm significantly improved (p<0.05) seed vigour properties including germination percentage, germination rate, height and fresh weight and nutritional values such as ash, protein, fat and carbohydrate. In addition, bioactive compounds including chlorophyll a and b, total chlorophyll and carotenoid content in ricegrass primed with 10 ppm FPH were higher than control. Phytic acid content in ricegrass primed with FPH at 5 and 10 ppm but not 15 and 20 ppm was lower than control. The ricegrass primed with FPH at 10 ppm yielded highest total phenolic content. Though, ABTS activity was not highest in rice primed with FPH at 10 ppm, DPPH and FRAP assays were highest.Conclusion: The ricegrass primed with FPH was significant improved seed vigour properties, nutritional value, bioactive compounds and antioxidant activity. The appropriate of FPH priming for ricegrass was 10 ppm because it could improve seed vigour, nutritional value and bioactive compounds including chlorophyll, carotenoid, total phenolic content and antioxidant activity determined as FRAP, DPPH and ABTS and reduce the anti-nutrient compounds as phytic acid.Keywords: Ricegrass, Fish protein hydrolysate, Nutritional value, Bioactive compound, Antioxidant

Background: The sailfin catfish (Pterygoplichthys pardalis) is a freshwater fish from the Loricariidae family, and is considered an invasive species in Indonesia. The fish is usually neglected and discarded. Its protein hydrolysate is the product of the breakdown of proteins into amino acids through the hydrolysis of acids, bases, or enzymes. Therefore, this study aims to determine the hydrolysate characteristics of sailfin catfish (Pterygoplichthys pardalis) proteins, produced with different pH and hydrolysis durations. Methods: The hydrolysis was carried out with variable pH (control, 5, 7, 9) and hydrolysis durations (12 and 24 hours) in three replicates. Results: The hydrolysis duration, pH, and interaction of both variables had significant effects (p<0.05) on the parameters of yield, antioxidant activity, degree of hydrolysis, protein levels, and ash content. Similarly, the moisture content, hydrolysis duration, and pH were significantly affected (p<0.05), while their interactions were not (p>0.05). The pH treatment had a significant effect on fat content (p<0.05), while the hydrolysis length and the interaction between the two had no significant effect (p>0.05). Based on this study, the best resulting production of fish protein hydrolysate (FPH) from sailfin catfish were a for a combination of pH 9 and a hydrolysis duration of 24 hours. The characteristics of FPH produced were as follows: a yield of 57.39%, antioxidant activity 63.99%, degree of hydrolysis 40.67%, water content 7.28%, ash content 7.63%, fat content 5.10%, protein content 34.51%, molecular weight 6.14 -118.17 KDa, total essential amino acids 49.30%, and nonessential amino acids 50.71%. Conclusions: Two factors affected FPH characteristics in sailfin catfish (Pterygoplichthys pardalis). The best processing conditions to obtain optimal characteristics for FPH were a yield of 57.39%, antioxidant levels of 63.99%, a DH of 40.67%, a moisture content of 7.28%, ash content of 7.63%, fat content of 5.10%, and protein content of 34.51%.
