Texture assessment effect

In frozen vegetables, health quality, nutritional quality, and aspects of sensory quality like color and texture can be objectively assessed and controlled also, in frozen potato products the effects of the thermal treatments included in the process have to be assessed due to their influence on texture, color, and nutritional value. However, in the case of overall assessment of sensory quality, only the consumer can perceive and process the overall blend of sensations that denote quality and cause consumers to prefer, accept, or reject a product. [Pg.166]

Lipids are important macromolecules in food. A food product s nutritional value as well as its flavor, texture, general palatability, and storage stability are affected by lipids. Therefore, both physical and chemical criteria are needed by the food processor to assess or monitor the quality of fats and oils. The basic characteristics of certain food items, such as edible oils, will be dependent upon their source. Variation from these norms can be ascertained before the oils are used in other foodstuffs. In effect, knowledge of the quality of the lipid before shipping the product to market, or use in fabricated foods, is of economic importance to the processor. [Pg.515]

Soil moisture can have a significant effect on decomposition (Swift et al. 1979). This is due, in part, to the fact that soil moisture can affect the metabolism of decomposer microorganisms. This effect can be modified by soil texture because bioavailable moisture is determined, in part, by the suction with which water is held between soil particles (matric potential). Thus, the calibration of soils to a known matric potential can lead to the assessment of the effect of bioavailability of moisture in soil (Hillel 1982) and allow for the comparison of process rates between soils at the same matric potential (Orchard and Cook 1983). [Pg.41]

This now raises the issue of what is the correct value of the / c ratio for any given material. The CIE Technical Committee TC 1-28 published recommendations on how to handle various parameters that can affect the judgments of color differences as CIE Publication 101 [54]. In that study, the parameter that stood out was the effect of surface texture on the judgments of lightness differences. Small differences in lightness can be assessed for specimens with smooth glossy surfaces but not in samples with textured, patterned, or rough surfaces. Thus studies in the literature... [Pg.38]

ASSESSMENT OF SOIL STRUCTURE (SOIL TEXTURE). The Structure of the soil is important for the water content, air content and thermal metabolism of the soil. It has determinative effects on plant growth and on root penetra-... [Pg.22]

Sensory evaluation is a scientific discipline that uses humans to measure the acceptability and sensory properties of food and other materials. Sensory properties important in food products include attributes of appearance, odor, taste, and texture. The use of humans as measuring devices is necessary because only humans can define what is acceptable, and in many cases, no instmmental or chemical method can adequately measure or replicate the human response. For this reason, sensory evaluation is a vital component in any quality assessment program. In such programs, sensory evaluation can be used to monitor product quality determine effects of alternative processing, ingredients, or formulations evaluate packaging and determine product shelf life. [Pg.453]

Based on the mineralogy controlling weathering and soil development, sensitivity of ecosystem to acid deposition is assessed with a comprehensive consideration on the effect of temperature, soil texture, land use and precipitation. The results show that the most sensitive area to acid deposition in China is Podzolic soil zone in the Northeast, then followed by Latosol, Dark Brown Forest soil and Black soil zones. The less sensitive area is Ferralsol and Yellow-Brown Earth zone in the Southeast, and the least sensitive areas are mainly referred to as Xerosol zone in the Northwest,... [Pg.497]

These authors have used the technique of lamellar decoration [76] which enables detailed assessment of cheu-acteristic mesophase defects and texture on a much finer scale than previously possible with conventional electron-microscopy preparations. The defects and texture existing in the polymer melt state are first retained by thermal quenching of the polymer fluid to room temperature. The glassy LCP film is then annealed above its glass transition, but below the melting point. Crystalline lamellae grow perpendicular to the local chain axis and effectively decorate the molecular director... [Pg.108]

Meanwhile, in domain-rich ferroelectric devices, besides the need for a direct visualization of internal residual stresses, a direct experimental assessment of domain texture and distribution is desirable, in order to control functional outputs. For example, a size effect on the ferroelectric phase transition in thin films may lead to a critical size of few tens of nanometers, below which the ferroelectric transition vanishes. [Pg.94]
