Abstract

Tannin is a major polyphenolic secondary metabolite widely distributed in the forestry sector and can be added to polymer matrices to manufacture bioactive films for food packaging. Tannins have functional properties as antioxidants, antibacterial, and anti-inflammatories. Tannins are classified into two types, namely condensed tannins and hydrolyzable tannins. Tannins have been used primarily in food, wood, leather, pharmaceutical, and other industries. In the food industry, tannins are used to develop food packaging, preservation, and the function of the food industry. Tannin molecules have the advantage of combining with polymers or polymer surfaces, for example, synthetic polymers, biopolymers, and micro- and nano-sized fibers, which will form new products whose physical and chemical properties increase in functional properties because of the presence of hydrophilic and nucleophilic groups. Combining tannins with a polymer can be done by one-step reactive extrusion, layer by layer, dynamic vulcanization, acetylation, and in situ extraction methods. This paper describes general information about tannins, followed by applications using tannins, tannin-based hybrid materials, and methods of combining tannins with a polymer for food packaging purposes. Keywords: active packaging, bioactive film, polymer, secondary metabolite, tannins

Abstract

Lamongan Regency, located in East Java, Indonesia, is a significant center for beef cattle production. Despite its prominence, studies on the identification and differentiation of Eimeria spp. parasites in this region are notably lacking. This research aims to address this gap by evaluating the prevalence of Eimeria spp. and identifying two pathogenic species: Eimeria bovis and Eimeria zuernii. The study involved the collection of 250 fecal samples from beef cattle raised on smallholder farms across Lamongan. Sampling was conducted during the rainy season to optimize the detection of Eimeria infections. Using the sugar flotation method, Eimeria oocysts were isolated from 5–10 g of fecal matter per sample. Molecular identification employed polymerase chain reaction (PCR) assays targeting ribosomal RNA’s internal transcribed spacer 1 (ITS-1) region to detect the pathogenic species. Fecal examination using the Whitlock test revealed a prevalence of Eimeria spp. at 44.45% (111/250). PCR analysis further identified E. bovis with a 238 bp amplicon in Solokuro District and E. zuernii with a 344 bp amplicon in Tikung District, highlighting the presence of these two pathogenic species in distinct geographic areas. The findings underline the need for further research that includes expanded sampling from different regions and cattle breeds and the application of varied diagnostic methods. Such studies will contribute to a more comprehensive understanding of the genetic diversity, distribution, and epidemiology of E. bovis and E. zuernii in Indonesia, supporting improved cattle health and management practices in the region.
