Abstract

The fermentation methods used for buffalo milk sometimes vary among the regions where the Minangkabau people live. The physicochemical and microbial loads of fermented milk produced from swamp buffalo milk in this study were evaluated. The spontaneous method (in a bamboo tube), combination of spontaneous (in a bamboo tube) and backslopping (with the addition of a previous dadiah to the milk) methods, as well as its extension in the form of the backslopping method (with the addition of a dadiah to the milk in glass bottle), were applied in fermented milk manufacturing. The moisture content, pH, titratable acidity (TTA), and lactic acid bacteria load of the samples were analysed. The fermentation method had significant effects on the pH, TTA, and lactic acid bacteria load (P<0.05); in contrast, a comparable effect on moisture content was detected (P>0.05). The pH value of the samples prepared via the backslopping method and the combination of spontaneous and backslopping methods was lower than that of the spontaneous method (P<0.05), while a higher TTA was observed (P<0.05). Compared with the other methods, the combination method resulted in a higher lactic acid bacteria load, followed by the back slopping and spontaneous methods (P<0.05). The combination method might be considered the best method. In cases where bamboo is unavailable, the backslopping method can be used as an alternative method for buffalo milk fermentation to continue obtaining the live microflora benefits of the previous dadiah. In summary, confirmation from the original methods and the extended method provided more choices for the community to produce fermented milk from swamp buffalo milk.

Abstract

This study aimed to evaluate the effect of adding indigenous microorganisms (IMO) derived from chicken feathers on the physicochemical properties of chicken feather flour, namely, color, microscopic structure, and crude fiber content. An experimental method with a completely randomized design (CRD) with five treatments and four replications was used in this study. The treatments were the addition of IMO chicken feathers at levels A (0%), B (1.5%), C (3%), D (4.5%), and E (6%) to fermentation feather meal. The parameters observed were color (L*, a*, b*), microscopic structure, and crude fiber content. The results showed that increasing IMO concentration significantly decreased lightness (L*), crude fiber content, and increased yellowness (b*) but did not significantly affect redness (a*). Microscopic observations revealed keratin structure degradation at higher IMO concentrations. The optimal concentration was 4.5%, resulting in balanced physicochemical properties of feather flour. These findings demonstrate the potential of IMO application for the sustainable utilization of chicken feather waste as a protein-rich feather meal.

Abstract

Eggs are animal products with high nutritional value that remain relatively affordable. Duck eggs contain protein, energy, and fat levels that are as high as those found in chicken eggs. Generally, eggs can be stored for approximately 14 days at room temperature; beyond this period, their quality declines as storage time increases. Therefore, preservation methods for duck eggs are necessary. This study aims to evaluate the effects of applying beeswax bio-coating at various concentrations on the weight loss, albumen index (AI), yolk index (YI), and haugh unit (HU) of duck eggs over a period of six weeks. The research utilized an experimental method with a Completely Randomized Design (CRD), with five treatments and four replications. The treatments involved dipping duck eggs in beeswax bio-coating at different concentrations: A (0%), B (4%), C (8%), D (12%), and E (16%). The observed variables included egg weight loss, albumen index, yolk index, and haugh unit. The findings indicated that the application of beeswax bio-coating significantly affected (p < 0.05) egg weight loss, albumen index, yolk index, and haugh unit. The optimal results were achieved with treatment D (12%), which recorded a weight loss of 1.956%, an albumen index of 0.084, a yolk index of 0.354, and a haugh unit value of 71.839. Suggestions for future research include conducting developmental studies to add other substances or materials to the 12% beeswax bio-coating to enhance its quality. Furthermore, further research is required to evaluate the effects of storing duck eggs treated with 12% beeswax bio-coating at low temperatures.
