Sensory evaluation

The Manual on Descriptive Analysis Testing for Sensory Evaluation was sponsored by Com-mittee E-18 on Sensory Evaluation. Descriptive analysis is a sensory method by which the attributes of a food or product are identified and quantified, using human subjects who have been specifically trained for this purpose.

The effect of chitosan, glucose and chitosan–glucose complex (CGC) on the microbial and postharvest quality of shiitake (Lentinus edodes) mushroom stored at 4 ± 1 C for 16 days was investigated. Mushroom weight loss, respiration rate, firmness, ascorbic acid, total soluble solids, microbial and sensory quality were measured. The results indicate that treatment with CGC coating maintained tissue firmness, inhibited increase of respiration rate, reduced microorganism counts, e.g., pseudomonads, yeasts and moulds, compared to uncoated control mushroom.

Neurologic Evaluation Peripheral sensory neuropathy is the major risk factor for diabetic foot ulceration (24, 26, 27, 46, 50). The patient history and physical examination utilizing the 5.07 SemmesWeinstein monofilament (10-g) wire are sufficient to identify individuals at risk for ulceration (26, 232-235). Vibration perception threshold assessment with the biothesiometer is also useful in identifying patients at high risk for ulceration (44, 57, 236). More sophisticated studies such as nerve conduction studies are rarely necessary to diagnose peripheral sensory neuropathy.

This chapter focuses on specific pharmacodynamic, pharmacokinetic, and drug delivery issues relevant to ocular therapy and imparted by the unique anatomy and function of this sensory organ, introduced at the outset of this chapter. Many of the pharmacological agents discussed here have been discussed in earlier chapters. Autonomic agents have several uses in ophthalmology, including diagnostic evaluation of anisocoria and myasthenia gravis, as adjunctive therapy in laser and incisional surgeries, and in the treatment of glaucoma....

Esthetics (also spelled aesthetics) is a subdiscipline of value theory or axiology, which is a branch of philosophy that studies sensory values, sometimes called judgments of sentiment or taste. Esthetics is closely associated with the philosophy of High Art. Esthetics includes art as well as the very purpose behind it. Esthetics as a branch of philosophy studies art, the methods of evaluating art, and judgments of art. Art has existed through all recorded human history. Art is unique to human beings because of our innate ability to abstract.

Falls Falls are a common event, particularly among the elderly. Modest changes in balance function have been described in fit older subjects as a result of normal aging. Subtle deficits in sensory systems, attention, and motor reaction time contribute to the risk, and environmental hazards abound. Epidemiologic studies have identified a number of risk factors for falls, summarized in Table 24-3. A fall is not a neurologic problem, nor reason for referral to a specialist, but there are circumstances in which neurologic evaluation is appropriate.

Since different diseases produce characteristic patterns of tissue damage, the quality, time course, and location of a patient's pain complaint and the location of tenderness provide important diagnostic clues and are used to evaluate the response to treatment. Once this information is obtained, it is the obligation of the physician to provide rapid and effective pain relief. The Pain Sensory System Pain is an unpleasant sensation localized to a part of the body.

Restaurant wine stewards or sommeliers generally provide sensory descriptions based on personal tasting, though accuracy may be questionable in restaurants which lack sufficiently trained or experienced employees. Some winemakers include descriptions with their wine shipments (Hochstein, 1994). While research into the impact of sensory descriptions on choice is limited, their broad use and inclusion in critical wine evaluations from The Wine Spectator and The Wine Advocate suggest a perceived importance.

Thaumatin is an intensely sweet-tasting protein. To identify the critical amino acid residue(s) responsible for elicitation of the sweetness of thau-matin, we prepared mutant thaumatin proteins, usingPichia pastoris,in which alanine residues were substituted for lysine or arginine residues, and the sweetness of each mutant protein was evaluated by sensory analysis in humans.
