Reducing fat content of fried foods by application of coatings is an alternative solution to comply with both health concerns and consumer preferences. The objective of the present work was to analyse the effect of coating formulation on the quantity and composition of oil-uptake by potato strips and dough discs, and the quality of frying oil after several frying batches. The effect of coating composition showed that the most efficient formulations were 1% methylcellulose (MC) and 0.5% sorbitol for fried potatoes and 1% MC and 0.75% sorbitol for dough discs. The most effective coating formulations reduced oil uptake by 35-40%, depending on the product. The increase in water content was 6.3% and 25.7% for potato strips and dough discs, respectively. Although coatings were effective barriers to reduce oil uptake in fried products, they did not modify oil composition as detected by HPLC analysis. Oil stability of frying oils, evaluated by total polar compounds and acidity, was within the allowed limits established by the Argentine Food Code (acidity <0.6mg KOH/g oil).

The qualitative assessment of preparation menu (AQPC) consists of a qualitative analysis of the menu composition regarding colors, preparation techniques, combinations, leafy offerings, fruits, sweets, types of meat and foods rich in sulfur. It is an important aid tool in the development of healthy and balanced menus. The objective of this study is to evaluate the quality of the menu of Food and Nutrition Units (UAN) through the AQPC method, to evaluate the main cooking methods of the main dishes, the main side dishes and types of proteins served and to classify the results of the application of the method. The data were tabulated in relation to the total days of the analyzed menus. The results showed percentages indicative of the nutritional quality of the menus. There was a high frequency of leafy leaves (59.1%) in both, being classified as ‘’Regular’’; with respect to colors, the university restaurant (UR) was classified as “Regular” (27.3%) and the RP as “Good” (18.2%); both restaurants were “Regular” in terms of sulfur-rich food, but ‘‘Great’’ in terms of fruit. Sweets were offered only in the RP, but at a low frequency (4.5%). There was no appearance of sweet + frying on both menus. In both restaurants, a high frequency of fried foods (59.1%) and fatty meats (40.9%) was observed. Regarding the meat preparation techniques, the roast and boil forms were verified only in the UR (31.8% and 4.5% respectively) and grilled and steamed only in the RP (4.5% and 9.1% respectively). The RP had a higher frequency of fried preparations (54.5%), stew (27.3%), whereas the stew was more frequent in the RP (40.9%). Regarding the types of proteins served, red meat was the most served type (UR, 72.7% and RP, 59.1%), chicken and fish were served more frequently in RP (40.9% and 4.5%, respectively). The main side dishes were rice, beans and flour, and most often they were served together both in the UR (72.7%) and in the RP (81.8%). It is concluded that the menus offer leafy and fruit in ideal quantities, but there is a high frequency of fatty meats and fried foods. In general, the AQPC method is a good tool to assist the nutritionist in the global and qualitative assessment of menus.

During the past investigations of immunoferritin localization of intracellular antigens in ultrathin frozen sections, we found that the degree of negative staining required to delineate u1trastructural details was often too dense for the recognition of ferritin particles. The quality of positive staining of ultrathin frozen sections, on the other hand, has generally been far inferior to that attainable in conventional plastic embedded sections, particularly in the definition of membranes. As we discussed before, a main cause of this difficulty seemed to be the vulnerability of frozen sections to the damaging effects of air-water surface tension at the time of drying of the sections.Indeed, we found that the quality of positive staining is greatly improved when positively stained frozen sections are protected against the effects of surface tension by embedding them in thin layers of mechanically stable materials at the time of drying (unpublished).
