Understanding and predicting sensory crispness of deep-fried battered and breaded coatings.

Crusted crispness refers to coatings with a dry and brittle surface contrasting a high-moisture core; it is desirable for the enjoyment and quality of deep-fried goods. This study aims to investigate instrumental measurements and sensory measurements of crispness. Deep-fried breadcrumb coatings of eight sizes were investigated: 4.0 mm, 2.8 mm, 2.0 mm, 1.4 mm, 1.0 mm, 710 µm, 500 µm, and 355 µm. Sensory profiling was carried out to develop a tailored lexicon for deep-fried battered and breaded shrimp. Principal component analysis highlights that large breadcrumb sizes correlate with crispness, hardness, particle size, surface color, color uniformity, surface irregularity, total porosity, maximum force, area, drop in force, number of sound peaks, and sound pressure level. Agglomerative hierarchical clustering was used to confirm clustering of samples according to breadcrumb size. Multiple factor analysis confirmed overall correlation between sensory measurements and instrumental measurements (RV = 0.810). Partial least squares regression was used to develop a predictive model for crispness from instrumental measurements (R2 = .854). The use of texture analysis and Acoustics provide information of the structures strength and deformation behavior, while X-ray microCT provides a high resolution and noninvasive method that acquires information on the internal morphology. These instrumental methods collectively demonstrate the relationship between microstructure to sensory. This study investigates how a change in the microstructure of deep-fried battered and breaded coatings affect crispness perception. These changes were investigated analytically and by using a sensory panel, this is important from a manufacturing perspective in order to understand what the major contributors are to a crisp texture. The key highlights of this study include both instrumental measurements and sensory measurements can be used to measure crispness as both types of testing are correlated. Changes in the size of breadcrumbs affect both instrumental measurements and sensory measurements. A predictive model can be re-simulated to allow prediction of crispness in deep-fried battered and breaded coatings.

An inner-city community's perspective on infant mortality and prenatal care.

Neither expanded Medicaid eligibility nor case-finding approaches have significantly increased use of early prenatal care. Failure to improve use points to the importance of further study of the broader community's perspectives on prenatal care and perinatal health issues. A convenience sample of 380 low-income, inner-city, black adults were interviewed with respect to their understanding of infant mortality, perceived barriers to and importance of prenatal care, and recommended numbers of prenatal visits. All respondents reside in a community with negative indexes of perinatal health as measured by infant mortality, low birthweight, and average number of prenatal visits. Fifty percent of the sample could correctly define the term infant mortality. The majority believed that prenatal care is very important and should begin in the first trimester of pregnancy. Respondents recommending the least number of prenatal visits (0-6) perceived financial, institutional, and attitudinal factors as barriers to care. Pregnant women's fear of detection of drug use was the most salient barrier regardless of the recommended number of prenatal visits, age, sex, employment status, or number of children. Changing health problems mandate continued monitoring of community perceptions and expectations of services such as prenatal care. Public health nursing is ideally positioned to articulate community values to policy makers and health care professionals concerned with perinatal health.
