Finished product quality

Textile fabric testing is vital to the quality control of down and feather products. Fabric that can confine down and feathers within predetennined volumes and shapes also prevents dust or mites from contaminating the down filling. Consequently, some basic testing of textiles is necessary for good quality control. 

A1 As an example, 800 cu in/oz, if converted to the metric unit (at an identical specific load of 0.149 g cm ), equals 436.81 kg, and is expressed in this form according to EN 12130 (1998). Psychologically, the larger cubic inch measurement is automatically identified with better quality. In addition, the easy to read, comma-free three digit cubic inch figure (in most cases displayed only in 10 or even 50 unit steps, which is easier yet to read and to conceive) is historically older. It is most likely to remain in friendly co-existence with metric units. 

Q2 Does 900 filling power (i.e. 900 cu in/oz) really exist, as sometimes claimed  

A2 Yes, but only in very rare cases and the supply of such down is very small. 

Since market demand may be much higher than the available down, buyers should be cautious before accepting a 900 filling power claim.

Proper selection of soy protein is critical to successful brine formulation and finished product quality (Table II). 

Textured Soy Proteins. Textured vegetable proteins, primarily textured flours and concentrates (50% protein and 70% protein, dry basis, respectfully) are widely used in the processed meat industry to provide meat-like structure and reduce ingredient costs (3-6, 9-10). Available in a variety of sizes, shapes, colored or uncolored, flavored or unflavored, fortified or unfortified, textured soy proteins can resemble any basic meat ingredient. Beef, pork, seafood and poultry applications are possible 03, 4-7, 15, 19) Proper protein selection and hydration is critical to achieving superior finished product quality. Textured proteins have virtually no solubility and, thus, no ability to penetrate into whole muscle tissue Therefore, textured soy proteins are inherently restricted to coarse ground (e.g. sausage) or fine emulsion (e.g. weiners and bologna) products, and comminuted and reformed (i.e. restructured) meat products. None are used in whole muscle absorption or injection applications (2-4, 6, 11). 

Another important analytical requirement concerns the quality control of the incoming ingredients and of the outgoing finished product. Quality, according to Taguchi (1986), is intended as the minimization of the variability about a target value, as indicated in Fig. 2.1. 

A variety of non-hydrocarbon species is found in crude oil. These compounds are found in all molecular weight ranges of crude oil components, but seem to concentrate in the heavier distillate and residual oil fractions. The effect of these materials on processing equipment, refining catalysts, and finished product quality can be dramatic. Corrosion, catalyst poisoning, and fuel stability problems can all be due to the effect of these nonhydrocarbon species. 

For example, finished-product release specifications such as content uniformity are rarely correlated to clinical evidence rather, they are set according to compendial test standards. Furthermore, the functional relationship between in-process material characteristics and finished-product quality is seldom known at a high level hence, the assigned in-process specifications for some operations may over- or underestimate the true level of process capability. As the level of process understanding in the pharmaceutical industry increases, development of science- and evidence-based in-process and release specifications will improve the reliability of Cpk as a tool for process characterization. 

PAT is a system for continuous analysis and control of manufacturing processes based on expeditious, real-time measurements during processing. They can measure quality and performance attributes of raw and in-process materials as well as processes to ensure acceptable finished product quality. What makes PAT forward-quality is that it can occur while the process is underway, as opposed to the more traditional approach of measuring quality at the end of the process. Clearly, this significantly supports the recall... 

Nutrition. Fats and oils are recognized as important nutrients for both humans and animals because they provide a concentrated source of energy, contain essential fatty acids, and serve as carriers for fat-soluble vitamins. Research studies have also indicated a relationship between saturated fats, cholesterol, and trans-isomers and the incidence of coronary heart disease. In many cases, shortening functionality can be maintained with formulations limiting cholesterol, the identified saturated fatty acids, and tran -isomers. Shortening formulation can also aid in reductions of fat consumption by development of more effective products to reduce the levels required to produce the desired functionality and finished product quality. 

The effect of adverse storage and transportation conditions has been reviewed by Faur (292), and Muys (216) has discussed the microbiological storage qualities of margarine. Dritschel (293) has detailed a rating system for evaluation of finished product quality based on appearance, texture, flavor, and packaging.

It is without argument that low-quality components (i.e. those that do not fully meet the desirable requirements), while sometimes being initially cheaper to purchase, will eventually produce lower in-house efficiency, coupled with lower finished product quality. 

This fairly simple example illustrates the need to review the quality route between design and conformance. Similar examples can be found in the QC role for process quality as well as finished product quality, but the following discourse, in order to be comprehensive, will concentrate on raw material control. 

The inspectorate of most national health organisations devotes equal investigations time to the QC operations and to the manufacturing process. This has been reflected in the corresponding attention paid by the legislature to the control of practices by research and clinical evaluation laboratories. It is essential that in the design stage of new product, the importance of the supplier s effect on finished product quality is not overlooked. Most modem products are the sum of many different parts and processes, all of which should be equally under control. 

The quality, ie, level of impurities, of the fats and oils used in the manufacture of soap is important in the production of commercial products. Fats and oils are isolated from various animal and vegetable sources and contain different intrinsic impurities. These impurities may include hydrolysis products of the triglyceride, eg, fatty acid and mono/diglycerides proteinaceous materials and particulate dirt, eg, bone meal and various vitamins, pigments, phosphatides, and sterols, ie, cholesterol and tocopherol as well as less descript odor and color bodies. These impurities affect the physical properties such as odor and color of the fats and oils and can cause additional degradation of the fats and oils upon storage. For commercial soaps, it is desirable to keep these impurities at the absolute minimum for both storage stability and finished product quality considerations. 

Process control implies measurement of critical parameters of raw materials and intermediates as they are converted to finished products, and monitoring and controlling the critical process parameters that may influence finished product quality. Process control is what parametric release is all about. In processes where the level of reliability in process control can be predicted to be high, there is a sound basis for eliminating the sterility test. Where process control is not so reliable, the sterility test should be considered as one part of the armory of process control, tests rather than as an overriding end-product test, in other words a Pass in the sterility test should never in these processes be allowed to overrule evident failure to meet all of the prescribed in-process test criteria. 

Production. All operations involved in the preparation of a pharmaceutical product, from receipt of materials, through processing and packaging, to completion of the finished product. Quality Assurance. See Part One. 

The capacity of metal, glass, or salt baths for continuous operation differs from that of batch-type (dipping) baths because the coefficient of heat transfer is increased by the movement through the bath of the strip or pieces being coated. That movement also enhances temperature uniformity as well as finished product quality. 

In the food industry LC is frequently used to determine the quality of the finished product. For example, it has been shown that the flavor quality of grape juice is directly linked to the amount and spectrum of organic acids present. Likewise, in the production of sour cream by fermentation, the quality of the finished product quality is related directly to the organic acid profile. Last, but not least and as pointed out above, LC techniques are also crucial in determining the quality of recombinant protein products. 

A higher mold temperature favors a uniform melt cooling rate, minimizing residual stresses, and improves the surface finish, mold release, and product quality. The mold cooling rate affects finished product quality. Polyether type TPU can set up better and release better. 

On-site dedicated injection molding plants located at automotive, appliance, and furniture assembly plants contribute to finished-product quality and lower finished-product costs.
