Post Harvest Loss

Moisture content is one of the most important factors determining grain quality during harvesting, storage, trading, processing, and transportation because high moisture will create problems for farmers, especially during postharvest activities such as mold growth, higher insect infestation, loss in seed germination, and low market price. A study was conducted to find out a precise moisture meter (MM) for moisture content (MC) determination during post-harvest activities of rice. John Deere moisture meter (JD MM), Moisture Probe and RiceterL MM were tested and calibrated to provide accurate result compared to that of Oven dry method. The average MC of same samples was found 11.4, 11.8, 12.3, and 13.1% by Oven dry method, Moisture Probe, RiceterL and John Deere MM, respectively. Standard deviations of the mean are 0.11, 0.17, 0.13 and 0.22, respectively by the corresponding moisture meters. Oven dry method i.e. drying whole kernels for 72 h at 105°C had the smallest standard deviation. This indicated long drying time and adequate drying temperature could ensure the precision of moisture determination. The reading of John Deere, Moisture Probe and RiceterL MM is higher by 1.7, 0.4 and 0.9%, respectively than that of oven dry method. Moisture measurement by these methods can lead to wide variations of conclusion. Moisture measurement by John Deere moisture meter is quicker and easier than Moisture Probe and RiceterL (MM).  However, adjustment procedure with respect to calibration is needed before use.Progressive Agriculture 27 (4): 511-516, 2016

Post Harvest Loss

Abstract. Storage of grain in bags is common in Africa, Asia, and many other less developed countries making a bag probing method well-suited for moisture content (MC) measurement. A low-cost meter was developed under a USAID project to reduce post-harvest loss (PHL). The meter, referred to as the PHL meter, measures the MC of maize and other grains based on relative humidity (RH) and temperature (T) measurements obtained by a small digital sensor located in the tip of a tubular probe that can be inserted into bags of grain or other grain bulks. Measurements are used by equilibrium moisture content (EMC) equations programmed into the meter to predict MC. A handheld reader connected to the probe provides a user interface.

The price paid for corn is usually based on 15.0 or 15.5 percent moisture content. However, corn must be dried below 13 percent moisture to ensure safe storage for a year or more. In the U.S., such stored corn cannot be directly remoistened before selling it, but it can be mixed with moist new-crop corn. Accurate moisture measurement of mixtures of dry and moist corn is important to permit adjustment of blending ratios to maximize profitability, but grain moisture meters are less accurate for mixtures of wet and dry grain. This research evaluated the differences between dielectric-type moisture meter results for mixed and equilibrated corn samples at different moisture levels and different measurement frequencies. Equilibrated grain samples tended to give lower moisture results than recently mixed grain samples - especially in the 1 to 10 MHz region. These differences permitted detection of mixtures by using moisture measurements at two frequencies.

Maize is known to be an important crop for food security in developing countries; and farmers have continued to experience post-harvest losses which lead to reduction in the quality or quantity of maize grains. The main causes of post-harvest losses are the storage insect, pests, improper drying and poor storage systems. Poor storage accounts for 5-10% loss and 5% loss is attributed to insect attacks. This research modified a one tonne metallic silo with the aim of studying the effects on moisture content and hectolitre weight of the maize grains. The moisture content was determined using moisture meter while the hectolitre weight was determined using extruded brass material. The study lasted for six months and analyses were carried out on the data collected using Duncan multiple range tests at 95% level of confidence. The moisture content was observed to reduce from 13.5% to 11.4% w.b while hectoliter weight which is the main determinant of the market value of the grain was observed to increase from 276 kg/ml to 288 kg/ml, this implies that there was increase in the cost value of the grain after six month of storage. The results showed that variations in moisture content along storage period were significant at (p ≤ 0.05).

Carrageenan is a derivative product of seaweed that used in various fields such as pharmacy, food and cosmetics. One of the most widely used carrageenan from seaweed was Eucheuma cottonii sp. The research was conduct to determine the effect of post-harvest seaweed pre-treatment on yields of Carrageenan. The first pre-treatment done by using the fresh seaweed that has been washed clean then directly dried. The second pre-treatment, washed seaweed soaked with clean water for seven days and then dried with a dryer. Drying time for the first and second pre-treatments is varied, then dried seaweed extracted with water to produce carrageenan. The analyses performed were moisture content of seaweed and yields of Carrageenan. The results of the research found that the initial moisture content of seaweed on the second pre-treatment was greater than the first pre-treatment. The variation of drying time on the first pre-treatment did not affect significantly on the yields, but in the second pre-treatment, yield of carageenan increased with accumulation drying time.

1. It is necessary for all those concerned with the production, processing, and handling of seedlike products such as coffee parchment and green coffee to have available a method for the rapid and simple determination of moisture content. 2. A review of the literature indicates that much work has been done on the moisture determination of the seed of commerce of the Temperate regions, but little information exists concerned with the moisture determination of coffee. 3. As an initial step in setting up a program to investigate methods of coffee-processing it was necessary to establish a quick, simple, and accurate method of moisture determination. Investigations by others indicated that the Kappa moisture-meter, manufactured by Messrs. Kappa Moisture Meter Ltd., U. K., was probably the most suitable instrument available for this purpose. 4. It was decided to use a distillation method as the primary means of establishing the relationship between the moisture content of the material and the meter reading. It was found that it was not only necessary to determine the meter reading but also the weight of the sample and the ambient temperature if reliable results were to be obtained. 5. The Kappa moisture-meter was calibrated both for coffee parchment and green coffee over the widest possible range of moisture contents likely ever to be encountered. 6. All the results were statistically evaluated. It was found that, if the weight of the sample and the ambient temperature were taken into consideration, the standard deviation from the regression or the standard error of estimate for both parchment and green coffee were very comparable to similar values obtained for other dielectric moisture-meters used for moisture determination in wheat over a much more limited range. 7. It was found that the range of the Kappa moisture-meter was sufficient for the entire range of moisture contents considered. The divisions on the meter scale were also found to be adequately spaced, so that all readings could be made with sufficient accuracy. 8. It was observed that there was a very close relationship between the weight of a given volume of moderately compacted coffee parchment and its moisture content. This relationship could perhaps form the basis of a cheap, simple way for roughly evaluating the moisture content of parchment coffee which would be sufficiently accurate for farm use. 9. It was considered that the most convenient method of determining the moisture content from the Kappa meter-reading, the sample weight, and the ambient temperature, is by means of a four-variable addition-type alignment chart or nomogram. 10. Though the linear regression equations established for Kappa moisture- meter, Serial No. 7755, are unlikely to be applicable to other moisturemeters of the same type, additional meters required can be calibrated from this original meter instead of by more tedious primary methods.

Abstract This study quantified the variability among 14 standard moisture loss-on-drying (gravimetric) methods for determination of the moisture content of corn distillers dried grains with solubles (DDGS). The methods were compared with the Karl Fischer (KF) titration method to determine their percent variation from the KF method. Additionally, the thermo-balance method using a halogen moisture analyzer that is routinely used in fuel ethanol plants was included in the methods investigated. Moisture contents by the loss-on-drying methods were significantly different for DDGS samples from three fuel ethanol plants. The percent deviation of the moisture loss-on-drying methods decreased with decrease in drying temperature and, to a lesser extent, drying time. This was attributed to an overestimation of moisture content in DDGS due to the release of volatiles at high temperatures. Our findings indicate that the various methods that have been used for moisture determination by moisture loss-on-drying will not give identical results and therefore, caution should be exercised when selecting a moisture loss-on-drying method for DDGS.
