Abstract

This research aims for developing immune-boosting products necessary. The active ingredient in Andrographis paniculate (AP) acts as an immunostimulant which can improve the work of the immune system. The first stage of research was a collection of bioactive compounds from KnapSack database of Kanaya, Dr. Duke's Phytochemical and Ethnobotanical were compiled and selected based on the online pass results of each bioactive compound as an immunomodulator and 10 active compounds were obtained which will be continued. The second stage of research was a docking molecular between whey proteins (β-lactoglobulin and α-lactalbumin) with active compounds from AP and casein (α-Casein, β-Casein, and κ-Casein). The highest binding affinity was obtained for α-Casein with Neoandrographolide at -9.2 Kcal/mol. The results of the complex α-Casein with Neoandrographolide (CC) and α-Casein with Neoandrographolide ultraheat (CCT) support the research, namely to function α-Casein as an encapsulant well as a transporter or drug delivery of Neoandrographolide without changing the conformation of casein and disturbing its function. However, the conformation of casein will change drastically during ultraheat treatment to maintain the conformation and binding with the Neoandrographolide ligand. In addition, it supports the simulation results of single α-Casein at ultraheat temperatures which show conformational stability that is not much different from single α-casein and complexes at physiological temperatures

Abstract

Ptilinopus melanosphila and Chalcophaps indica, known as Puna birds among local people of the Sula Islands, North Maluku, Indonesia, while Treron aromaticus, known as Puna Giu, belong to the Columbidae family. These birds are frequently hunted for consumption due to the delectable taste of their meat. This study aims to examine the essential Omega-3 (n-3PUFA) nutritional content, utilizing these two avian species (Ptilinopus melanosphila and Chalcophaps indicia) as samples. Local perceptions consider these birds as identical, hence this study also provides insights into the disparities between the two species based on meat quality analysis. The analysis encompasses proximate analysis, fatty acids, and amino acids, conducted on 6 samples, each encompassing 3 breast meats. These samples were mixed and blended, followed by chemical analysis at the integrated laboratory of Universitas IPB Baranangsiang, with proximate analysis executed at PAU IPB. The results reveal that Ptilinopus melanosphila meat contains crucial nutrients for human consumption, specifically long-chain omega-3 unsaturated fatty acids (n-3PUFA), which are more abundant compared to Chalcophaps indica and several other meat products. The myriad of significant benefits offered by this avian species underscores the importance of recommending its preservation to parties engaged in ex-situ conservation efforts. Furthermore, it is advocated to stimulate the establishment of regional culinary businesses specializing in nutrient-rich Black-Naped Fruit Dove meat.
