The moisture content determination was carried out on a KERN DBS 60-3 moisture balance running a semi-automatic program, which heats the sample at 120 °C until the moisture content is stable for 30 s. Ash content (%) was determined after incineration of BSG samples in a muffle furnace at (500 °C for 24 h). Particle size distribution was studied by passing three freeze-dried BSG portions though a set of sieves with decreasing mesh size (1.0, 0.5, 0.25 and 0.125 mm).

To determine the plasticiser content, it was necessary to determine the moisture content in the examined films. Moisture content was determined using a moisture analyser (KERN DBS60-3, Germany). Approximately 0.7 g of foil was dried at 105 °C for 15 min.
The content of triphenyl phosphate (CTPP) was calculated using Equation (3) [32 ], where MIS and MTPP are the molar weights of IS and TPP respectively, PIS is the purity of IS, PTPP is a dry matter of the CTA sample, IIS is the integral of IS (8.3795 to 8.2925 ppm), ITPP is the integral of TPP (7.5273 to 7.1982 ppm), NIS is 1, NTPP is 15, mIS, and mCTA are weights of IS and CTA.

The contents of dietary supplement dosage forms were combined before loss on drying evaluation to ensure homogeneity. A total of 20 dosage units of each hard-shell capsule (S1–S25) were opened to collect powder; the samples were ground if necessary. A total of 20 dosage units of each tablet (S30–S35) were powered using a porcelain mortar and pestle. A total of 10 g of powder and resin samples (S36–S51) was ground into a fine powder and mixed thoroughly. The samples were weighed (about 1.0 g) using the analytical balance AG254 (Mettler Toledo, Greifensee, Switzerland) and distributed on the aluminum sample plates (90 mm) as evenly as practicable to a depth of about 5 mm before being transferred into moisture analyzer DBS-60-3 (Kern and Sohn GmbH, Balingen, Germany) according to the protocol described in USP 43-NF 38 guidelines, <731> chapter “Loss on drying” in triplicate [30 ]. The procedure was performed at a temperature of 105 °C until constant weight.

The moisture content (MC) of the beetroot waste extract powder (BWEP) was measured using a moisture analyzer (KERN DBS 60-3, Berlin, Germany) set at 100°C. A calibrated chromometer (CR-10 Plus, Konica Minolta, Osaka, Japan) was used to measure the color attributes, including lightness (L*), redness (a*), and yellowness (b*). Respectively, Chroma (C*), hue angle (h°), and total color differences (∆E) were calculated using Equations 1 , 2 . All measurements were done in triplicates. where ∆L, ∆a*, and ∆b* represents changes in lightness, redness, and yellowness/blueness, respectively.

Genotypes were harvested when 70% of the pistils had darkened. Gland heads of trichomes are clear or slightly amber at the beginning of the growth cycle. Prior to harvest, when cannabinoid levels reach their maximum, they turn cloudy. The state of trichomes was monitored with binoculars. Genotype FED was harvested at 137 DAP. Harvest of genotype KANADA and 0.2x-genetic took place at 142 and 156 DAP, respectively. Inflorescence and leaves were dried at a temperature of 20 °C for 14 days. After the drying process, dry matter was weighed and recorded in gram per single plant to determine the dry weight (DW). Subsequently, the dried plant material was ground with an ultracentrifugal mill (Retsch, Type ZM 200, Haan, Germany) to acquire a homogeneous powder, with a particle size of 1 mm. The residual moisture of each samples was measured with a moisture analyzer (DBS 60-3 of Kern and Sohn GmbH, Balingen, Germany).

The adsorbent resin Lewatit® VP OC 1064 MD PH (Lewatit) is a neutral un-functionalized crosslinked polystyrene resin with a wide range pH (0-14) and thermal (-20 to 120 °C) stability. The 0.44-mm-0.54-mm white, opaque, porous beads have a surface area of 800 m 2 /g, a pore volume of 1.2 cm 3 /g, and an average pore diameter of 5 nm-10 nm [28] . Preliminary data show that this resin is suitable for the adsorption of polyphenols such as HCAs. Before the experiments, the resin was preconditioned as recommended by the supplier and described elsewhere [29] (link). Briefly, the resin was washed consecutively with 6% HCl, distilled water and 4% NaOH until the pH of the cleaning water was close to that of distilled water. The water retention percentage of the resin was determined to be 64%, using a moisture analyser (DBS 60-3, Kern).

The moisture content of PS was measured in a moisture analyzer at 100 °C (DBS60-3, KERN, Balingen, Germany). The procedure of PS moisturizing was done following the method described by Rekas et al. [29 (link)]. PS (200 g) was sprayed with the pre-calculated amount of water, thoroughly mixed, sealed in zipped polyethylene bags, and equilibrated at 4 ± 2 °C for 48 h. This procedure was applied to moisturize the seeds to obtain a moisture content of 6% before microwave pretreatment. Water is a polar molecule and an important heat transfer medium during seeds microwave pretreatment and therefore PS moisturizing was vital [30 (link)]. A mass balance was used to calculate the amount of water to be added to the PS to obtain 6% moisture content. After 48 h of equilibration, the PS moisture content was checked in order to verify moisture homogeneity in the samples.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
