The lack of research on the rich sucrose in tiger nut meal has been a major obstruction to the comprehensive utilization of tiger nut (Cyperus esculentus L.). In this study, for the first time, tiger nut meal was used to producing non-centrifugal sugar (NCS). Three samples - NCS-W1 (NCS prepared by water extraction and concentrated at 115 °C), NCS-W2 (NCS prepared by water extraction and concentrated at 135 °C), and NCS-E (NCS prepared by 70 % ethanol-water extraction and concentrated at 115 °C) were obtained, with yields of 14.25-14.59 %. These samples and sugarcane NCS products (NCS-C1, NCS-C2, NCS-L) were compared and analyzed in terms of color, pH, turbidity, soluble solid content, and proximate composition. Their Fourier-transformed infrared spectra, crystal patterns, and thermal stabilities were also analyzed. The NCS-W1, -W2, and -E showed excellent performance, and they were better than sugarcane NCS products in terms of free radical scavenging ability and cytoprotective effects. Differences in phenolic acid composition, flavonoid composition, amino acid, mineral content, and vitamins C and E content were also analyzed. This work demonstrates that tiger nut meal might be a new source of NCS. As such it would contribute to the full utilization of tiger nut.

Mycotoxins pose significant health risks due to their prevalence in food products and severe health implications, including carcinogenicity. This study investigates the bioavailability of mycotoxins aflatoxin B1 (AFB1), ochratoxin A (OTA), and zearalenone (ZEN) individually and combined, in the presence of identified polyphenols from tiger nut beverage (TNB) and tiger nut by-product (TNBP) using the in vitro model Caco-2 cells, which simulates the human intestinal barrier. The objective is to understand how bioactive compounds from TNBP can mitigate the effects of AFB1, OTA and ZEN (and their combination) by bioavailability interference, contributing to safer food products and innovative food safety strategies.

This study assessed the safety of trace metal concentrations in locally produced nutritive food-drinks consumed in Yenagoa metropolis, Bayelsa State, Nigeria. Three different drink types (viz, tiger nut juice, a mixture of tiger nut and soya bean juice and soya bean juice) were purchased from various locations in Yenagoa metropolis, Bayelsa State, Nigeria, between January and February 2024. Thirty samples were analyzed for trace metals using atomic absorption spectrophotometry.

The margarine market is growing globally due to its lower cost, ease of availability, large-scale commercialization, and expanding market in the bakery and confectionary industries. Butter contains greater amounts of saturated fat and has been associated with cardiovascular diseases. The trans fats generated through the hydrogenation process have several adverse impacts on human health, such as the risk of atherosclerosis, coronary heart disease, postmenopausal breast cancer, vision and neurological system impairment, type II diabetes, and obesity.

Tiger nuts are rich in both oil and starch. In this paper, an immiscible binary solvent consisted of water and hexane was used to separate oil and starch from tiger nut with the assistance of ultrasound. The effects of various factors including ultrasonic power, ultrasonic time, extraction temperature, water-hexane ratio and solid-liquid ratio on the oil yield were examined.
