The results showed that the GSS meat extracts exhibited potential antimicrobial activity against and . A peptide band with a molecular weight < 5 kDa was obtained for the characterization of AMP candidates after separating the selected extract using SDS-PAGE, and the sequences were acquired by LC-ESI-MS analysis.

Effect of processing treatments on the allergenicity of nuts and legumes: A meta-analysis.

The effective food processing to reduce nuts and legumes allergenicity could not be easily and directly concluded from reading a few published reports. Therefore, we conducted a meta-analysis to investigate this issue. A literature search was conducted in eight electronic databases from January 2000 to June 11, 2021.

The Bioactivity Prediction of Peptides from Tuna Skin Collagen Using Integrated Method Combining In Vitro and In Silico.

The hydrolysates and peptide fractions of bigeye tuna () skin collagen have been successfully studied. The hydrolysates (HPA, HPN, HPS, HBA, HBN, HBS) were the result of the hydrolysis of collagen using alcalase, neutrase, and savinase. The peptide fractions (PPA, PPN, PPS, PBA, PBN, PBS) were the fractions obtained following ultrafiltration of the hydrolysates.

Chemical and Antioxidant Characteristics of Skin-Derived Collagen Obtained by Acid-Enzymatic Hydrolysis of Bigeye Tuna ().

The utilization of bigeye tuna skin as a source of collagen has been increasing the value of these skins. In this study, the quality of the skin was studied first. The skin after 14 h freeze-drying showed a high protein level (65.

Molecular analysis of a fibrin-degrading enzyme from Bacillus subtilis K2 isolated from the Indonesian soybean-based fermented food moromi.

The screening of proteolytic and fibrinolytic bacteria from moromi (an Indonesian soybean-based fermented food) yielded a number of isolates. Based on morphological and biochemical analyses and sequencing of the 16S rRNA gene, the isolate that exhibited the highest proteolytic and fibrinolytic activity was identified as Bacillus subtilis K2. The study was performed to analyze molecular characteristic of a fibrin-degrading enzyme from B.

Emulsifying properties and antioxidant activity of soy protein isolate conjugated with tea polyphenol extracts.

Functional properties of proteins, such as emulsification, foam formation and antioxidant activity, can be improved by conjugating the proteins with phenolic substances. We reported here changes in the structural, physicochemical and functional properties of Soy Protein Isolate (SPI) after conjugation with phenolic substances in the green tea and black tea extracts. Conjugation of SPI with tea extracts were conducted using alkaline treatment (pH 9.

Proteomic study of bioactive peptides from tempe.

Tempe is a traditional Indonesian fermented soybean mostly produced in small industries and sold locally throughout the country. Studies on the bioactive peptides in tempe are rare. Here, we studied bioactive peptides in samples from three tempe producers with different degrees of sanitation.

Thrombus Degradation by Fibrinolytic Enzyme of Stenotrophomonas sp. Originated from Indonesian Soybean-Based Fermented Food on Wistar Rats.

Objective. To evaluate thrombus degrading effect of a fibrinolytic enzyme from food origin Stenotrophomonas sp. of Indonesia.

Purification and Characterization of a Fibrinolytic Enzyme from Bacillus pumilus 2.g Isolated from Gembus, an Indonesian Fermented Food.

Bacillus pumilus 2.g isolated from gembus, an Indonesian fermented soybean cake, secretes several proteases that have strong fibrinolytic activities. A fibrinolytic enzyme with an apparent molecular weight of 20 kDa was purified from the culture supernatant of B.

Fermentation RS3 derived from sago and rice starch with Clostridium butyricum BCC B2571 or Eubacterium rectale DSM 17629.

Resistant starch type 3 (RS3) is retrograded starch which is not digested by human starch degrading enzyme, and will thus undergo bacterial degradation in the colon. The main fermentation products are the Short Chain Fatty Acid (SCFA): acetate, propionate and butyrate. SCFA has significant benefit impact on the metabolism of the host.

DLBS1033, a protein extract from Lumbricus rubellus, possesses antithrombotic and thrombolytic activities.

The medicinal value of earthworm has been widely known since the history of Asian ancient medicine. This present study aims to determine the mechanism of action and effect of a standardized extract of Lumbricus rubellus named as DLBS1033. The fibrinogen degradation, antiplatelet aggregation, and ex vivo antithrombotic assay using human blood were performed to study antithrombotic activity.

Effect of Sauropus androgynus leaf extracts on the expression of prolactin and oxytocin genes in lactating BALB/C mice.

Sauropus androgynus is traditionally consumed by Indonesians and is believed to increase breast milk production during lactation. Lactation, a process of milk synthesis and secretion, occurs with the help of 2 hormones, prolactin and oxytocin. The expressions of genes encoding prolactin and oxytocin were analyzed in lactating BALB/C mice brains using qRT-PCR.
