36、sh proverb claims that fish, to taste right, should swim three times-in water, in butter and in wine. The early efforts of the basic scientists in the food industry were directed at improving preparation, preservation, and distribution of safe and nutritious food. Our memories of certain foodstuffs
37、eaten during the World War suggest that, although these might have been safe and nutritious, they certainly did not taste right. Nor were they particularly appetizing in appearance or smell. This neglect of the sensory appeal of foods is happily becoming a thing of the past. Now, in the book Princip
38、les of Sensory Evaluation of Food, the authors hope that it will be useful to food technologists in industry and also to others engaged in research into problem of sensory evaluation of foods. An attempt has clearly been made to collect every possible piece of in-formation that might be useful, more
39、 than one thousand five hundred references being quoted. As a result, the book seems at first sight to be an exhaustive and critically useful review of the literature. This it certainly is, but this by no means is its only achievement, for there are many suggestions for further lines of research, an
40、d the discursive passages are crisply provocative of new ideas and new ways of looking at established findings. Of particular interest is the weight given to the psychological aspects of perception, both objectively and subjectively. The relation between stimuli and perception is well covered, and i
41、ncludes a valuable discussion of the uses and disadvantages of the Weber fraction in evaluation of differences. It is interesting to find that in spite of many attempts to separate and define the modalities of tastes, nothing better has been achieved that the familiar classification into sweet, sour
42、 and bitter. Nor is there as yet any clear-cut evidence of the physiological nature of the taste stimulus. With regard to smell, systems of classification are of little value because of the extraordinary sensitivity of the nose and because the response to the stimulus is so subjective. The authors s
43、uggested that a classification based on the size, shape and electronic status of the molecule bear the merit for further investigation, as does the theoretical proposition that weak physical binding of the stimulant molecule to the receptor site is a necessary part of the mechanism of stimulation. A
44、part from taste and smell, there axe many other components of perception of the sensations from food in the mouth. The basic modalities of pain, cold, warmth and touch, together with vibration sense, discrimination and localization may all play a part, as of course, does auditory reception of bone-c
45、onducted vibratory stimuli from the teeth when eating crisp or crunchy foods. In this connection the authors rightly point out that this type of stimulus requires much more investigation, suggesting that a start might be made by using subjects afflicted with various forms of deafness. It is well kno
46、wn that extraneous noise may alter discrimination, and the attention of the authors is directed to the work of Prof H.J. Eysenck on the “stimulus hunger“ of extroverts and the “stimulus avoidance“ of introverts. 86 The reviewer uses a Polish proverb at the being of the article in order to _ . （ A） i
47、ntroduce, in an interesting manner, the discussion of food （ B） show the connection between food and nationality of food （ C） indicate that there are various ways to prepare food （ D） impress upon the readers the food value of fish 87 The reviewers appraisal of Principles of Sensory Evaluation of Fo
48、od is _ . （ A） mixed feelings （ B） indifference （ C） high praise （ D） faint praise 88 Which of the following statements concerning the system of classification in taste is TRUE? （ A） The writer feels upset that there is no better system of classification than the familiar one of sweet, sour, bitter
49、salty. （ B） Psychological perception of the taste is objective because no subject judgment is involved. （ C） It is extremely difficult to classify smell, as its hard to make objective judgment on the stimulus. （ D） The classification is subjective, for there is no relation between the perception and the stimulus. 89 Which statement does the writer of the article NOT express, either directly or by implication? （ A） Sharply defined classif
