Post-production handling

The aim of this chapter is to provide a concise synopsis of the factors that promote degradation during post-harvest handling, processing, and storage, and the strategies to preserve the green color of the most commonly consumed chlorophyU-rich foods. Some considerations about the production and characteristics of natural and semisynthetic chlorophyll derivatives for use as food colorants are also presented. 

Harvesting and post-harvest handling account for about half of the labor involved in kava production. Particular attention needs to be given to harvesting, handling, drying, and storage since these operations have a major impact on the quality of kava and its price. 

The initial relatively small number of animals and acreage (see Table 5.2) required for biopharmaceutical production facilitates the implementation of poUen control, containment practices, quahty assurance procedures, and monitoring systems for all aspects of animal growth and crop production, harvesting, post-harvest handling, storage, transportation, and bioprocessing [350]. 

Sun and co-workers exploited the selectivity in the non-covalent functionalization of SWNTs with planar aromatic molecules, such as derivatized porphyrin or pyrene (Figure 6.3), for the post-production separation. The separation method simply splits the starting nanotube mixture by selectively solubilizing semiconducting SWNTs and leaving their metallic counterparts behind, and consequently is capable of handling significant sample quantities. Experimentally, as-produced samples of... 

The goals of cotton textile processing for producing sustainable products are to reduce water use, energy use, and chemical use use safer/ greener chemicals and minimize inputs to the enviromnent (air, water, solid waste). Post-harvest handling/processing of cotton includes ... 

Post-production phase The processing conditions (addition, extrusion, pelletization, etc.) and product handling. 

The chromatographic traces from the analysis of the headspace of rice can be deceiving. The stark differences between two samples may initially appear to provide an easy method for varietal, location, and growing differences. However, on close examination, the differences usually are a result of Upid oxidation products and contaminants, which occur during post-harvest handling and storage processes. True differences that can be used to distinguish between the aromas of rice are quite subtle. 

Of concern, however with any sludge management issue, are the costs for recovery of potentially valuable by-products as in the case of the cable plant and the costs associated with concentrating the sludge to a form that it can be handled in post processing operations. 

In the post-combustion chamber temperatures of 900 °C to 1200 °C are reached. The kiln can - like any rotary kihi - handle solid, fluid and gaseous waste streams. Based on the heat capacity of the waste, halogen content, and potential slag formation, an optimal mixture of wastes is determined. By choosing the feed carefully, production of high-quality HCl can be assured. Furthermore, in this way a minimum formation of dioxins and furans can be ensured. 

A hazard evaluation is performed before assessing the technical feasibility of a new process. Chemical handling/storage criteria, critical process conditions, quality measurements, thermal hazards, and post-campaign cleanup are considered in the introduction of any new process/product. 

The most important factors contributing to the production of biogenic amines during postharvest handling are the duration of storage and the storage temperature. Both the post-mortem formation of amino acids and their rapid decarboxylation are temperature dependent. 

There is little that can be done to affect the chemical composition of the ash as far as SiO A1203, and Fe203 are concerned. The chemical composition of the post-combustion ash is primarily a function of the chemical composition of the non-combustible matter in the coal feed to the boiler. The moisture specification is primarily for storage and handling considerations since fly ash used as a pozzolan has historically been stored, transported, and metered as a dry product. There is no technical reason that fly ash must be dry for use as a concrete admixture.
