Abstract

Lysozyme is one of the constituent proteins of chicken egg white that plays an important role in a protection system during the embryo growing process. Lysozyme protection systems can be applied in food and for health. This paper aims to describe the role of egg white lysozyme which has the antibacterial activity to improve food safety and health. Mechanism and activity of lysozyme protection can be explored by understanding the structure of proteins, type of amino acids, and the sequence of amino acids. The mechanism of lysozyme antibacterial activity against Gram positive bacteria occurs through its ability to breakdown the peptidoglycan glycosidic bonds in the bacterial cell wall membrane. The antibacterial activity of lysozyme can be increased when its normal lysozyme form was denatured/hydrolyzed through modifying the lysozyme structure by heat and enzymatic treatment. Heat treatment will reveal the active site of lysozyme after denaturation, leading to the destruction of the bacterial cell wall membrane. Enzymatic treatment through hydrolysis process of hydrolysis by protease enzymes will generate antibacterial peptides, which have the ability to inhibit the growth of Gram positive bacteria and Gram negative bacteria. Antibacterial lysozyme peptides and heat treated lysozyme are dominated by hydrophobic amino acids and positively charged to facilitate interaction between lysozyme and lipopolysaccharide which coats peptidoglycan. Antibacterial lysozyme peptide can be used as an antibiotic and a safe natural preservative compared to synthetic material and can reduce the risk of destructive bacteria and pathogenic bacteria. Lysozyme peptide is potential to protect human health since it has also other activities such as inhibition of angiotensin-converting enzyme, antihypertensive, antitumor, antioxidant, and antiviral agents.

Abstract

Coffee was a type of beverage that widely consumed and favored by Indonesians. The level of coffee consumption in Indonesia increases every year. Lampung is one of the largest coffee producing provinces in Indonesia with Tanggamus being the 2nd highest coffee-producing district in Lampung. This has led to the growth of Small and Medium Enterprise (SME) of coffee at Tanggamus area, one of which was the processing of Robusta ground coffee. These SME produced robusta coffee to be marketed throughout Indonesia and often export to customers abroad. Therefore, SME owners must maintain the quality and quality of coffee by implementing GMP (Good Manufacturing Practices). This causes the need for evaluation of GMP at SME Tanggamus ground coffee to ensure product quality and quality as well as Yeast and Mold Plate also Total Plate Count testing to determine the level of product safety. In addition, there we also gived some recommendations for the application of the HACCP system to SME. Based on the results of observations on the application of GMP at SME Robusta Tanggamus Ground Coffee, there are 12 elements that are checked according to the requirements and there are 2 elements that should have an effort to improve. The results of YMP and TPC tests on Tanggamus robusta ground coffee products showed that the product did not contain mold, yeast, and microbes. Based on the recommendations for the application of the HACCP system, regular observations of the water used for washing coffee beans are required.

Abstract

Weight is one of the important variables that need to be considered in producing carcass and meat. This study aimed to determine the weight of live quail, fresh carcass, frozen carcass, quail carcass and breast meat after thawing. The weighing was done before the slaughtering process, after becoming fresh carcass, after freezing, after thawing, and after separating the quail breast meat. Thawing loss and the total loss was measured to know the loss percentage of the weight of quail carcass. Weighing produces the weight of live quail is 248,50 ± 20,72 grams, fresh carcass weight after slaughtering is 167,50 ± 17,06 grams, frozen carcass weight after freezing is 163,85 ± 17,06 grams. Carcass weight after thawing sequentially at 6-8°C (24 hours), 24-26°C (6 hours), 22-23°C (2,5 hours), and 55°C (1 hour) amounting to 158,20 ± 19,87 grams, 165,60 ± 19,40 grams, 167,80 ± 12,40 grams, 157,20 ± 19,84 grams, and quail meat sequentially 50,20 ± 6,26 grams, 52,60 ± 6,31 grams, 53,20 ± 3,70 grams, 49,80 ± 6,22 grams. The weight percentage of carcass inversely proportional to thawing loss and total loss produced.  The results showed that carcass weight decreased after cutting, freezing, and thawing. The heaviest weight of quail meat and carcass and the lowest total loss of carcass were produced from thawing at a temperature of 22-23°C.

Abstract

Lisozim adalah enzim hidrolase yang bisa diisolasi dari putih telur ayam. Penelitian bertujuan untuk mengkarakterisasi lisozim termodifikasi dari putih telur ayam lokal dengan SDS-PAGE dan mengukur aktivitas lisozimnya. Lisozim dari putih telur ayam Sentul terisolasi dimodifikasi dengan perlakuan panas. Lisozim dikarakterisasi dengan SDS-PAGE. Aktivitas lisozim diujikan terhadap Micrococcus lysodeikticus. Profil SDS-PAGE menunjukkan lisozim masih memunculkan sedikit ovotransferin dan ovalbumin sebelum dimodifikasi. Perlakuan 60°C tidak mengubah profil SDS-PAGE dan hasilnya mirip seperti lisozim terisolasi awal tetapi perlakuan 75°C menyebabkan ovotransferin menghilang. Setelah perlakuan 90°C, selain ovotransverin menghilang, protein baru muncul yang diduga lisozim berbentuk dimer. Profil SDS-PAGE lisozim termodifikasi menjelaskan lisozim tetap mempertahankan aktivitasnya walaupun terjadi perubahan profil lisozim.

Abstract

Fruit chips in Darsa Small and Medium Industry at Lampung products do not include an expiry date on the packaging label as important information that consumers must know. This study aims to estimate the shelf life of jackfruit, pineapple and banana chips using the Accelerated Shelf Life Test (ASLT) method with the Labuza equation critical moisture content approach model. The research was conducted by determining the initial water content, critical water content and equilibrium moisture content with other supporting variables such as packaging permeability, slope (b), product solid weight and packaging area. Based on the research results, the initial water content and critical water content of each fruit chips were 0.0348 and 0.0582 gH2O/g solid for jackfruit chips, 0.0348 and 0.0493 gH2O/g solid for pineapple chips, 0.0525 and 0.0741 gH2O/g solid for banana chips. while the equilibrium moisture content at 75% relative humidity at 30°C is -0.0537 g H2O/g solid in jackfruit chips, 0.01128 g H2O/g solid in pineapple chips and 0.0119 g H2O/g solid in banana chips. The Hasley equation model is the most suitable model to describe the water sorption isotherm phenomenon in jackfruit chips, while the Chen-Clayton equation model is suitable to describe the water sorption isotherm phenomenon in pineapple and banana chips products. The prediction of the shelf life of jackfruit and banana chips packed in nylon aluminum foil stored at 30°C with 75% RH is 2.6 months for jackfruit chips and 3 months for banana chips. While the prediction of the shelf life of pineapple chips packaged in metallized plastic paper is 4.2 months.

Abstract

Kacang kedelai merupakan bahan pangan yang banyak diolah. Salah satu olahan kacang kedelai adalah minuman sari kedelai yang dapat diolah lebih lanjut menjadi produk fermentasi berupa soygurt. Proses fermentasi sari kedelai tidak menghilangkan keseluruhan aroma yang tidak diinginkan sehingga perlu penambahan sari buah nanas yang bisa menghilangkan aroma tersebut serta membantu pertumbuhan bakteri asam laktat (BAL), mengatur pH dan keasaman pada soygurt yang berperan dalam menghasilkan mutu soygurt yang sesuai. Tujuan penelitian yaitu untuk mengetahui pengaruh, memperoleh konsentrasi terbaik, serta korelasi dari penambahan sari buah nanas terhadap kandungan BAL, pH dan keasaman soygurt. Penelitian ini menggunakan rancangan acak lengkap dengan tiga kali ulangan. Perlakuan konsentrasi penambahan sari buah nanas sebanyak 0%, 5%, 10% dan 15% serta parameter uji berupa total BAL, pH dan keasaman. Hasil penelitian menunjukkan, berdasarkan uji ANOVA (α=95%), setiap konsentrasi sari buah nanas berpengaruh terhadap karakteristik produk soygurt. Peningkatan penambahan sari buah nanas mampu meningkatkan total BAL dan keasaman serta menurunkan pH soygurt. Penggunaan 15% sari buah nanas adalah konsentrasi terbaik yang dapat ditambahkan pada soygurt berdasarkan uji Duncan (α=95%). Selain itu, total BAL meningkat sejalan dengan penambahan konsentrasi sari nanas serta berkorelasi positif dengan keasaman (R²=0.9844) namun berbanding terbalik dengan pH pada produk soygurt (R²=0.8487).
