Harapin Hafid, Peni Patriani — Mon, 31 Jul 2023 00:00:00 +0000

Buffalo meat has a good nutritional profile for the development of processed livestock products to meet consumer demand. For some reason, buffalo meat is less desirable to consumers because of its dark colour, coarser fibres, and tougher texture. Innovative product development is necessary as consumer demand tends to shift to ready-to-eat products. Processing buffalo meat into patties is an innovation in product development. Quality products require beneficial ingredients. Fenugreek seeds (Trigonella foenum-graecum) are herbal spices that are beneficial for health, contain protein, fibre, stabilizers, and emulsifiers, and have the potential for product development. The purpose of this study was to determine the effects of anise seed addition on the characteristics of buffalo meat patties. This study used a factorial Complete Randomized Design (4x2) with 4 replications. The factor I was the addition of fenugreek powder, F0 = control or 0%, buffalo meat patty dough + (F1 = 3% fenugreek powder; F2 = 6% fenugreek powder; F3 = 9% fenugreek powder). Factor 2 had a storage time of D1 = 30 days and D2 = 60 days.

Bacteria from animals raised for food that have developed antimicrobial resistance (AMR) may serve as a vehicle for its transmission from animal to human. Nevertheless, the antibiotic resistance profile of Escherichia coli from raw meat is scarcely reported, especially in North Sumatra. The aim of this investigation was to investigate the retail raw meat for the presence of E. coli and its antimicrobial resistance pattern. We purchased 80 packages of fresh meat products from four traditional markets located in Deli Serdang and Medan. Escherichia coli was isolated by an established microbiology test and a phenotypic antimicrobial susceptibility test was conducted by the method of disk diffusion. The data analysis of antibiotic resistance and multi-drug resistance (MDR) levels was performed by using WHONET 5.6. The antibiotic resistance dissimilarity between the two regencies was analyzed by using chi-square analysis. This study observed about 19 E coli isolates (23.7%) were obtained from raw meat. Resistance toward the antibiotics listed as critically important for veterinary and human therapy is increasing concern for public health. The isolates were highly resistant to ampicillin and tetracycline. Meanwhile gentamycin is susceptible. The MDR level of E. coli in both regencies of North Sumatra was about 21.05%. This finding contribute essential information on AMR in food animals and can be used to improve local and regional plans for the administration of antibiotics to livestock.

The research method is performed using laboratory experiments with a completely randomized design (CRD), followed by Duncan analysis (DMRT) when there are significant or highly significant differences in each treatment. This research focused on the nanoparticles of cocoa polyphenols in the formulation of the nano-polyphenol cocoa whey protein with 4 treatments (T0: 0%, T1: 5%, T2: 10%, T3: 15%) and 3 replications. The observed variables include total phenolic, antioxidant activity, particle size, emulsion activity, and emulsion stability. The difference in the concentration of the nanoparticles of cocoa results in highly significant differences (P<0.01) in total phenolic, antioxidant activity, and particle size. Gave a significant difference (P<0.05) in the emulsion activity, but does not show a significant difference in the emulsion stability (P>0.05). It can be concluded that cocoa 15% nanoparticles (T3) are the best treatment from other treatments and is able to synergize with whey protein isolate (WPI), improve emulsion quality and have natural antioxidant content used as an alternative for food fortification ingredients
