In this work, an analytical method for the determination of Cd and Pb in natural coconut water samples, industrialized coconut water samples and coconut milk using high-resolution continuum source graphite furnace atomic absorption spectrometry (HR-CS GF AAS), after minimum treatment of the sample was developed. The analytical method was applied to 46 samples collected in Salvador, Bahia (Brazil). The ranges of concentrations obtained were: 0.42-18.72 μg L Cd and <0.70-36.32 μg L Pb for natural coconut water samples (n = 14); <0.06-1.49 μg L Cd and 6.57-29.02 μg L Pb for industrialized water coconut samples (n = 16); and <0.10-5.93 ng g Cd and <0.85-22.41 ng g Pb for coconut milk samples (n = 16). For all samples, Cd and Pb concentrations were below the maximum tolerated values recommended by Brazilian Health Surveillance Agency (Agência Nacional de Vigilância Sanitária, ANVISA).

Composite polymers are promising solution to structural setbacks of starch and alginate-based films due to their hydrophilic attributes. Hence, this study aimed to investigate young coconut jelly powder (CJP), an under-utilized by-waste, as a filler using the casting method to develop a novel biocomposite from increments of CJP (1-3 %) to a blended resin of arrowroot starch, sodium alginate, and glycerol. Moreover, the films were characterized by physicomechanical (visual aspect, thickness, color, moisture content, tensile strength, and elongation at break); surface microstructure; water barrier (water vapor permeability, water solubility, and water activities); thermal, crystallinity, and functional group properties; soil, river water, and seawater biodegradability; and coating application in cherry tomato.

The nutritional value of a food is linked to the quality and quantity of the nutrients it contains. It offers a major advantage in establishing a food table composition (FTC) which is a tool that provides information on the quantity of nutrients contained in a food. Furthermore, certain natural beverage are not taken into account in the FTC.

Background: Benign prostatic hyperplasia (BPH) is a disease linked to the hormonal imbalance that occurs during aging and over the last decades, complementary and alternative medicines have come on the scene as a treatment option for BPH, such as herbal medicines. Coconut oil has been shown to be capable of interfering in testosterone-induced BPH. However, until now there is no study of the effect of coconut oil during aging.

We successfully enhanced bacterial cellulose (BC) production in low-cost coconut water (CW) at 37 °C by low-nutrient adaptation of Komagataeibacter xylinus MSKU 12. In this study, the BC yield was significantly increased by simultaneous coculture fermentation of MSKU 12 with Saccharomyces bayanus in Hestrin-Schramm (HS) and CW media. Coculture fermentation at 30 °C produced BC yields of 13.
