Comparison of Cooking Qualities of Acorn Starch with Other Starches

Abstract: The characteristics of pasting and gelation of acorn starch was studied with a view to elucidate the cooking quality of the starch. The comparison of the results with those of other starches (mung bean, arrowroot, and chestnut) gave the following findings : 1. Starch granules of acorn and chestnut swelled gradually with heating, and those of mung bean and arrowroot swelled rapidly. 2. The profile of the amylogram of acorn starch was somewhat similar to that of chestnut except for the set-back curves. The set-back curves of amylograms showed that the viscosity of the chestnut starch paste decreased with time while those of others increased. 3. Iodine affinity of a starch was in the order, mung bean> acorn> chestnut> arrowroot. 4. In textural measurements of starch gels, mung bean has the largest values of hardness and gumminess. Acorn has the second largest values. 5. Sensory tests showed no significant difference between mung bean starch gel and acorn starch gel with respect to preference.

Measurement of the Clothing Microclimate Volumes (Part 1)

Abstract: Wearing a clothing assembly, we have a numerous space between skin and outermost layer of clothing. Its quantities means air volumes of the interand intra-clothing, which is an important factor to explain thermal properties, clothing functions and aethetical features. This paper describes a new technique for estimating the clothing microclimate volumes. This method is based on the substitution water for the interclothing air, that is, an experimental clothing made of PVC film is hermetically sealed to exclude any external air with adhesive tapes and the interclothing air is exchanged for water, and then it is deaired with an air syringe. According to this method, we can obtain sufficient accuracy within an error of •} 0.5 liters with the average value of three experiments, so this is a useful measurement of clothing microclimate volumes. If clothing design is the same, it can be considered that there is no effect of textile properties for one.
