Bread Quality: Moisture, Volume, and Color

The moisture content of the bread was measured using an HB43-S moisture analyzer (Mettler Toledo, Switzerland). The specific volume of the bread was expressed by the ratio of volume (mL) and weight (g), and the volume of the bread was determined by the millet displacement method.
Meanwhile, the color of the bread crumbs was determined by a spectrometer color analyzer (Lab Scan XE, Hunter Lab, USA). The total difference of color (ΔE) was calculated as follows: ΔE=(LL0)2+(aa0)2+(bb0)2
where L indicates lightness, a indicates the red/green value, and b indicates the blue/yellow value. L0, a0, and b0 are the color of PGR0 bread.

Soil Carbon and Density Analysis

All samples were stored field moist at +4°C until further analysis. The undisturbed field moist samples were weighed for bulk density (BD) and water content (SWC) determination. In a second step, the soil from each core was homogenized and subsamples were taken and the weight loss after drying at 105°C for 48 h was determined. Based on the weight loss of the subsample, the theoretical weight loss of the entire core can be calculated, and the bulk density [g cm -3 ] and volumetric water content [cm 3 cm -3 ] of the entire core can be estimated.
Additionally, one part of the homogenized field fresh subsample was taken for organic carbon content (Corg) analysis.
Soil organic carbon (Corg) content was determined by dry combustion on a Leco RC 612 multiphase carbon analyzer (Co. LECO Instruments GmbH, Germany) at the central chemical laboratory ZEA-3 of the Forschungszentrum Jülich GmbH.
For the Accelerated Solvent Extraction (ASE) of boscalid residues, sieved and homogenized subsamples were used and the actual gravimetric water content (g g -1 ) was determined at time of extraction using a Moisture Analyzer HB43-S (Mettler-Toledo AG, Greifensee, Switzerland).

J. gendarussa leaves were collected from Pacet, Purwodadi, Surabaya, Gempol, Makassar, and Cibodas between September 2012 to January 2013 (Table 1). Samples were properly authenticated by Department of Pharmacognosy and Phytochemistry, Airlangga University, Surabaya. Mature, dark green leaves of five different plants were collected from each location in triplicate; the leaves were air-dried and powdered. Moisture contents (MC) of the samples were 9.6 ± 1.7%, n = 105 (by using Moisture Analyzer HB43-S, Mettler Toledo). The maximum permitted level of MC of the herbal medicine was 12%, w/w [31 ].
Soil collection was performed by using composite sampling. Fifteen sub-samples were collected randomly 6–8 inches from the surface [32 ].
Methanol, 2-propanol, and formic acid were analytical reagents from Merck (Darmstadt, Germany). Purified water was from Sigma-Aldrich (St. Louis, MO, USA), acetic acid from J.T. Baker (Phillipsburg, NJ, USA), and NaOH from Agilent (Agilent solution for HPCE). All samples were filtered through a 0.2 µm Agilent Econofilter PVDF 13m.

Moisture Content Analysis of Kemenyan

Moisture content of the kemenyan resin was determined by using a Moisture Analyzer HB43-S (Mettler Toledo, USA). The moisture content of the kemenyan fruit was measured by using a drying method. Each part of the fruit, particularly exocarp, mesocarp, endocarp and endosperm were dried for 24 h in an oven at 103C until constant weight [11] (link). The fruit parts were then crushed using a blender and filtered using a 60-mesh sieve for further analysis.

Saccharification of Deacetylated Corn Stover

Check if the same lab product or an alternative is used in the 5 most similar protocols
Saccharification experiments were carried out using deacetylated, dilute acid-pretreated corn stover. The biomass was analyzed for moisture content using an automatic moisture analyzer (Mettler Toledo Moisture Analyzer HB43-S, Mettler Toledo, Greifensee, Switzerland) and carbohydrate composition was determined as previously described [33 ]. These measurements were used to target a biomass loading of 2% and an enzyme loading of 20 mg/g glucan. Saccharification was performed at two different temperatures (50 and 60 °C) using two different enzyme mixtures: enzymes produced by the fungus T. aurantiacus and Novozymes Cellic CTec2. Saccharification reactions (50 mL) were set up in triplicate alongside biomass and enzyme controls using 2% biomass, 100 mM citrate buffer (pH = 5), and 20 mg/g glucan T. aurantiacus or CTec2. Reactions were continuously mixed at 180 rpm and 500 µL aliquots were collected every 24 h for 96 h. At each sampling time point, the volume was adjusted for evaporation with distilled H2O. Sugar concentrations were measured via HPLC for glucose and xylose and concentrations from the controls were subtracted from their respective samples before calculating yield.

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.
