Significant Differences In Appearance Research Articles

Effects of chilling hot boned meat with solid carbon dioxide

SummaryThe effect of carbon dioxide chilling on drip, appearance and sarcomere length was investigated by cooling hot beef semifendinmu muscles from one end with solid carbon dioxide, thus obtaining a range of cooling rates covering carbon dioxide and conventional chilling within single muscles.Drip ranged from 3 to 12% and correlated with the chilling rate except where freezing and subsequent thawing occurred. Statistically significant differences in appearance were found but are commercially unimportant. Sarcomere length and cooling rate were found to be unrelated but this may be due to limitations in the apparatus used.

Evidence for appearance of “lysis independent” procoagulant activities in collagen or thrombin stimulated platelets

The availability of procoagulant activities in platelet suspensions lysed by sonication correlated directly with the degree of lysis (loss of LDH and 51Cr). Separate measurements of platelet factor 3 (PF3) and Factor V/Va activity revealed significant differences in appearance of these platelet activities in sonicated cell suspensions. Platelet factor 3 activity increased almost in parallel to the loss of 51Cr, whereas Factor V/Va activity became available at a significant slower rate. This might be explained by the localization of Factor V/Va activities inside the α-granules and therefore not immediately available on the surface of the partially lysed platelets. No increase in lactate dehydrogenase or 51Cr-loss was observed during 12 min incubation of platelet suspension with collagen or thrombin, whereas both PF3 and Factor V/Va activities increased. Thus, the high platelet factor 3 activity of 34% (lysed platelets 100%) measured in thrombin stimulated platelet suspensions probably represents “lysis-independent” activity.

Evaluation of Pickles from Cucumber Plants1 Treated with 2-Chloroethylphosphonic Acid

Abstract Cucumbers from plants of a gynoecious cultivar treated with 0, 240, or 480 ppm 2-chloroethylphosphonic acid (Ethrel)were made into fresh-pack pickles and brine stock and evaluated by experienced judges. Fruit from Ethrel-treated plants were shorter than those from untreated plants. Otherwise there were no significant differences in appearance, flavor, texture, firmness, bloater formation, or acceptability of the processed product.

ケイ光X線によるアルミニウム陽極酸化皮膜中のアルミニウムおよびイオウの配位数に関する研究

It was reported in the previous paper that the anodic coating of aluminum, which had been prepared from sulfo-salicylic acid or sulfuric acid solution as electrolyte, showed amorphous Al2O3, but at was proved by X-ray diffractiometry to be changed to γ-Al2O3 by heating at 800°C.Various methods have been proposed in order to investigate the atomic bond an the amorphous state. It is believed that fluorescent X-ray method would be available for measurement of co-ordination numbers of atoms. Then, the authors attempted to determine chemical shift of the co-ordination numbers of Al and S in the above amorphous Al2O3 for measurement of these numbers.The results obtained were as follows:1) Both of aluminum atoms in the anodic coatings prepared from sulfo-salicylic acid and sulfuric acid solutions as electrolytes, had co-ordination numbers of 6-fold or 4-fold like that of γ-Al2O3. It proved that there was no significant difference in appearance between the both coatings.2) The co-ordination numbers of sulfur in both of the anodic coatings were measured in the same manner as in aluminum. It was shown that the bonding of sulfur atoms was similar to that of SO42--bond.
