Abstract

Chitosan is a natural polymer with positive charge that is good to be applied in the pharmaceutical field as a drug carrier. However, commercial chitosan has a large molecular weight and low degree of deacetylation, so its application is limited due to its low solubility in water. This study aims to determine the effect of the depolymerization method of two classes of chitosan on the market. The types of chitosan used to produce chitooligosaccharide are pharmaceutical grade and food grade. The method used were UV-C light irradiation (75 minutes), papain enzyme hydrolysis (15 g/L for 16 hours, 40oC and pH 5) and a combination of UV and enzymes. The results showed that the grade of chitosan and the depolymerization method affected the characteristics of the product. The three methods used in pharmaceutical grade chitosan produce chitooligosaccharide which dissolved directly in water with a neutral pH. Chitooligosaccharide had yield of >62%, whiteness degree of 99.33%, molecular weight <5.5 KDa, and degree of deacetylation >85%. Food grade chitosan which has been depolymerized by different methods cannot be dissolved in water with a neutral pH. Food grade chitosan through the combination of UV+enzyme depolymerization has the same deacetylation quality as pharmaceutical grade chitosan.

Abstract

Ulvan merupakan polisakarida bersulfat utama dari rumput laut Ulva yang memiliki aktivitas biologis penting. Umumnya ulvan diekstrak menggunakan suhu tinggi dan dengan rentang waktu yang lama, oleh karena itu diperlukan metode ekstraksi alternatif yang dapat menghasilkan ulvan yang memiliki kualitas yang baik namun tetap mendukung konsep efisiensi energi. Salah satu metode green extraction yang dapat mengurangi penggunaan pelarut organik dan energi yang tinggi selama ekstraksi adalah dengan bantuan gelombang ultrasonik. Tujuan penelitian ini adalah untuk menentukan waktu, suhu dan jenis pelarut dengan bantuan ultrasonik yang paling baik dalam menghasilkan rendemen dan karakteristik ulvan yang sesuai dibandingkan dengan ulvan yang diekstraksi dengan metode konvensional atau tanpa bantuan ultrasonikasi. Pada penelitian tahap awal digunakan kombinasi antara jenis pelarut (akuades, HCl dan NaOH) dengan kondisi ekstraksi suhu rendah (50, 60, dan 70℃) selama 45 dan 90 menit dengan bantuan ultrasonik. Rendemen tertinggi ulvan diperoleh dari ekstraksi menggunakan NaOH pada suhu 70℃ selama 90 menit dengan bantuan ultrasonik sebesar 16,90±0,45%. molekul dan viskositas ulvan yang dihasilkan dengan berbantu ultrasonik menunjukkan penurunan nilai dibandingkan dengan tanpa ultrasonikasi. Hasil Fourier-transform infrared spectroscopy mengkonfirmasi pita serapan grup sulfat yang merupakan residu gula rhamnose pada panjang gelombang 1125 cm-1 dan C-O-S pada 983 cm-1. Ulvan yang diekstrak dengan sonikasi menunjukkan kandungan sulfat 39, 58 dan 53% untuk masing- masing pelarut akuades, HCl dan NaOH. Perlakuan ultrasonikasi memberikan pengaruh pada kandungan sulfat 2-14% lebih tinggi dibandingkan dengan sulfat yang dihasilkan dari metode konvensional.

Abstract

Various enzymes are used in the food industry to improve product quality. The enzyme transglutaminase is used to modify proteins in various foods through the formation of inter- and intramolecular epsilon-(gamma-glutamyl) lysine bonds. Previous studies have revealed that using transglutaminase in cheese production can increase the yield and enhance the characteristics of various types of cheese. However, the enzyme concentration, temperature, and pH influence the quality of cheese. This review aimed to discuss the potential of transglutaminase in cheese production. Our analysis showed that transglutaminase catalyzes the formation of covalent bonds between milk proteins (crosslinking), which results in a greater amount of casein trapped from whey and a higher yield of curd. Transglutaminase can also reduce production costs without negatively affecting cheese quality. These findings should prove useful in developing cheese products to improve consumer satisfaction.

Abstract

Extraction of fish oil from the by-products of tilapia and carp can be achieved using an appropriate extraction process. The purpose of this study was to determine the proportion of acetone and fish oil solvents in relation to the oxidation parameters, iodine number, and concentration profile of omega-3 fatty acids present in tilapia and goldfish oil. This study utilized a completely randomized design, in which the treatment ratios of acetone and oil solvent were varied as 3:1, 4:1, 5:1, 6:1, and 7:1 (v/v). The following parameters were examined: the chemical composition, free amino acids, acid value, peroxide value, p-anisidine, total oxidation, iodine value, and fatty acid profile.The omega-3 levels in tilapia and carp were 1.20% and 1.53%, respectively. An Iodine Number Test was employed to identify the most effective solvent treatment, revealing a 5:1 (v/v) ratio as the optimal solution. The increase in the value of omega-3 in tilapia oil amounted to 1.76%, whereas that in carp oil increased from 0.78% to 2.96%, resulting in an average increase of 2.31%.

Abstract

Lobster shells are a by-product that can be used as a raw material for making chitin and chitosan. However, lobster shells contain a high amount of minerals that cover the chitin polymer on the shell. This chitin can be converted into chitosan by deacetylation process. Efforts that can be made to increase the efficiency of the chitosan extraction process from lobster shells are by pre-treatment using hydrochloric acid. The purpose of this study was to determine the pre-treatment time of lobster shells with hydrochloric acid and to produce nanochitosan from lobster shells. The results of this study indicate that the pretreatment time has a significant effect on the yield value of chitosan. The highest yield of chitosan was produced from the acid pre-treatment with a soaking time of 120 hours with a value of 15,6%. The quality of lobster chitosan from the best treatment has met the quality requirements based on SNI. Nanochitosan was successfully synthesized by ionic gelation method with a particle size of 357,76 nm and spherical shape based on SEM photos. Lobster nanochitosan has the potential to be applied in various fields, such as food, agriculture,and biomedical.

Abstract

Fishery Ulva lactuca is a potential green seaweed species that causes green tides and has not been utilized. U. lactuca has the potency to attract cellulolytic bacteria due to its high carbohydrate content. U. lactuca is commonly found on the southern seacoast of Java Island, one of which is Ujung Genteng Beach, Sukabumi, Indonesia. In this research, we investigated the potential of cellulolytic bacteria from U. lactuca. Sources of bacteria are coming from the environment, the surface of the seaweed, and inside the seaweed (endophytes). To be able to determine the origin of the potential bacteria, the total plate count (TPC) was calculated with treatment without washing, washing with distilled water, and washing with a combination of distilled water and alcohol. From these bacteria, cellulolytic activity was tested using CMC media and morphological characterization. The most bacteria were found in the treatment without washing, as much as 7.48 Log Cfu/ml. The washing process reduced the TPC to 5.88 and 5.7 Log Cfu/ml in the treatment of washing with distilled water and washing with a combination of distilled water and alcohol, so that endophytic bacteria were obtained. The bacterial isolate with the highest cellulolytic potential was UW 1(1)1 5A1 from the non-washing treatment with a cellulolytic index of 2.25. These Gram-positive bacteria were in the form of filamentous lobates with a matte cream color with cocci-shaped cells. Meanwhile, the potential endophytic bacteria were Gram-positive coccus bacteria UW 3(1)1.2 with a cellulolytic index of 0.85. Both isolates have the potency to degrade cellulose.
