Abstract

Cascara, the dried outer pulp and skin of the coffee cherry is usually discarded as waste. However, there is a growing interest in reutilizing this coffee cherry by-product as a unique product. This study aims to determine the effect of fermentation time on the physical and chemical properties of Nata de Cascara Arabica with a SCOBY starter. The material used in this research was Arabica cascara coffee as the raw material for making kombucha. The research method was designed as a Completely Randomized Design (CRD) with fermentation time as the factor, conducted in five repetitions. Fermentation periods of 8, 12, 16, and 20 days were analyzed for various physical and chemical parameters, including SCOBY’s thickness, yield, color, moisture content, and crude fiber. The data on the results of physical and chemical properties were analyzed using Analysis of Variance (ANOVA) at a 95% confidence level. If differences were found, the Duncan test was applied. The results showed that longer fermentation times significantly affected (p<0.05) moisture content and color (Redness), while thickness, yield, color (lightness), and crude fiber content increased. The best treatment for making Nata de Cascara Arabica is fermentation for 20 days.

Abstract

Daging ayam petelur afkir memiliki kandungan nutrisi yang tidak jauh berbeda dengan daging ayam kampung, namun dikarenakan umur yang tua, ayam petelur afkir memiliki kelemahan yaitu dagingnya keras dan liat. Meskipun memiliki karakteristik daging yang alot, ayam petelur afkir memiliki kelebihan diantaranya adalah mengandung protein yang tinggi dan lemak yang rendah. Guna mempertahankan kualitas dan karakteristiknya, daging perlu disimpan dalam keadaan beku. Thawing merupakan cara yang untuk mencairkan atau menyegarkan kembali bahan pangan yang telah disimpan beku sebelum dilakukan pengolahan lebih lanjut. Apabila proses thawing dilakukan dengan cara yang kurang tepat maka dapat menyebabkan penurunan kualitas daging salah satunya kualitas fisik daging. Penelitian ini bertujuan untuk mengetahui kualitas fisik berupa nilai pH dan daya ikat air daging ayam petelur afkir terhadap berbagai metode thawing yang diberikan. Bahan yang digunakan dalam  penelitian ini adalah daging ayam petelur afkir beku bagian dada dan akuades. Penelitian menggunakan uji rancangan acak lengkap dengan 4 perlakuan yaitu (T0) tanpa pembekuan dan thawing, (T1) thawing dengan air suhu ±20oC, (T2) thawing dengan air suhu ±30oC, dan (T3) thawing dengan air suhu ±40oC. Sampel yang telah diberi perlakuan thawing dilakukan pengujian nilai pH dengan pH meter dan pengujian daya ikat air dagng, Sedangkan data hasil pengujian nilai pH dan daya ikat air dianalisis dengan menggunakan uji Analysis of Variance (ANOVA). Analisis data dilakukan dengan menggunakan aplikasi SPSS 22.0 pada taraf signifikansi P≤0,05. Apabila terdapat pengaruh perlakuan, maka dilakukan uji lanjutan Wilayah Ganda Duncan. Perlakuan thawing dengan berbagai metode dengan kisaran suhu 20-40oC memberikan hasil bahwa thawing dapat menurunkan kualitas fisik daging ayam petelur afkir. Metode thawing yang menggunakan suhu semakin tinggi akan semakin menurunkan nilai pH dan daya ikat air daging ayam petelur afkir. Post-laying hens have a nutrient content that is not much different from native chicken meat (ayam kampung), but due to old age, they have a hard and tough meat. Despite their drawback, laying hens have the advantage that the meat contains high in protein and low in fat. In order to maintain its quality and characteristics, meat needs to be frozen. Thawing is a way to thaw or refresh food that has been stored frozen before further processing. If the thawing process is done in an inappropriate way, it can cause a decrease in the quality of meat, especially the pHysical quality of meat. This study aims to determine the pHysical quality in the form of the pH value and the water holding capacity of post-laying hens against various thawing methods. The material used in this research is frozen post-laying hen meat (chest) and distilled water. The study used a complete randomized design test with 4 treatments namely (T0) without freezing and thawing, (T1) thawing with water temperature ± 20°C, (T2) thawing with water temperature ± 30°C, and (T3) thawing with water temperature ± 40°C (waterbath). Samples that have been given a thawing treatment were tested for pH values with a pH meter and testing for water holding capacity, while the results of pH values and water holding capacity were analyzed using the Analysis of Variance (ANOVA) test. Data analysis was performed using the SPSS 22.0 application at a significance level of P≤0.05. If there is a treatment effect, then the Duncan Double Region continued test. Thawing treatment with various methods with a temperature range of 20-40°C gives the result that thawing can reduce the pHysical quality of post-laying hens. The thawing method that uses the higher temperature will further reduce the pH value and water holding capacity of post-laying hens.

Abstract

Bananas are a type of climateric fruit that undergoes post-harvest ripening, so bananas are easily damaged and have a short shelf life. Kepok banana flour is one of the food diversification products that can increase add value of kepok bananas. The production of kepok banana flour produces brown flour, so the appearance of flour is less attractive. Research aimed to improve quality of kepok banana flour using citric acid. The experimental design used was a Completely Randomized Design (CRD) with 5 treatments and 4 replications. The treatments given were citric acid concentrations of 0%, 0.2%, 0.4%, 0.6%, and 0.8%(w/v). The results obtained were whiteness index values of 75.07%-78.20%, water content of 3.05%-3.55%, reducing sugar of 0.03%-0.012%, color of 1.76-2.16, aroma of 2.00-2.80, and overalls of 2.68-2.92. Increase in the citric acid concentration may increase the reducing sugar, whiteness index, and water content kepok banana flour. The best treatment in the study was a concentration of 0.8% among others.

Abstract

Human carcinogenic compound formaldehyde (alternative name, formalin) adulteration in food is inappropriate and illegal. However, its simple and cheap procedure in giving desired food preservation effect becomes the factor of its prevalence in Indonesian community. Our current study focuses on the usage of formaldehyde in meatball products which are sold in bulk without refrigeration in traditional market set up. Eighty different packages of meatballs were collected following accidental sampling method from small groceries in Tembalang, Semarang, Central Java in 2019. Samples were characterized for their formaldehyde content (AOAC 931.08), total plate count, moisture and organoleptic properties. Formaldehyde was found in 1 sample at the level of 176.2 ppm. Whereby, it was among only 4 % of samples that met the maximum microbial limit of 5 log CFU/g. The particular sample was characterized by pale color, rather slimy surface, chewy and weak meatball aroma. Note, this characteristic is not unique and is shared by several other samples. Therefore, this study brings an update that formaldehyde adulteration is still prevalent. The adulterated product has hardly distinctive sensorial properties which make self-evaluation difficult, thus exposing consumers to potential food safety risks.

Abstract

Kepok banana flour (KBF) contains fructo-oligosaccharides (FOS) which can stimulate the growth of Lactobacillus plantarum bacteria in the digestive tract. The encapsulation technique is done to maintain the viability of probiotic bacteria from environmental conditions by packaging using coating materials like skim milk and maltodextrin. This research aims to determine the effect of adding KBF with different concentrations on Lactobacillus plantarum encapsulates. The research design used was a completely randomized design (CRD) with 5 treatments and 4 replications. The treatment given was a concentration of KBF of 0, 2, 4, 6, and 8%. The results obtained were a lactic acid bacteria (LAB) viability value of 8.72 Log CFU/g-9.16 Log CFU/g, a pH value of 6.55-6.43, yield value of 23.39%-23.43%, color of 3.36-3.12, aroma of 2.80-2.88, texture of 3.08-2.92, and overall, 3.12-3.36. The addition of 8% KBF can increase LAB viability, color, and texture, but reduces the pH value, yield, and aroma of Lactobacillus plantarum encapsulates and produces a well-encapsulated microcapsule morphology.
