Mancozeb residues were not detected in treated crop samples (apples, dried onion, and grapes) that were analyzed as a part of the comprehensive California Priority Pesticide Program for 1989 (Okumura et al. 

It has been shown that apples dried by osmosis and then frozen compared favorably with the conventional frozen fruits [144,179], Osmotic dehydration preceding freeze drying shortens the time of the process and yields fruits superior to those not treated by osmosis [15,79,97], Osmotic dehydration followed by vacuum drying gives products that are very stable upon storage [65],...

Pieces of apple (usually slices from peeled and cored fruit) which have been dried by artificial means to a moisture content of 24% or less. Discoloration during drying is prevented by treating the pieces with sulfur dioxide. Compared to fresh apples, dried pieces of apple contain about 5 times the level of calories, carbohydrates, and potassium. About 5 lb (2.3 kg) of peeled, cored apples (equivalent to between 5 and 6 lb of fresh apples) are required to make 1 lb (0.45 kg) of dried apple pieces. Certain other dried apple products may contain added sugar or syrup.

Pectin. Pectin [9000-69-5] is a generic term for a group of polysaccharides, mainly partially methoxylated polygalacturonic acids, which are located in the cell walls of all plant tissues. The main commercial sources of pectin are citms peel and apple pomace, where it represents 20—40% and 10—20% of the dry weight respectively. The pectin is extracted, the extract purified, and the pectin precipitated (50) increased extraction times lead to the production of low methoxyl pectins.

The propionamide can be dried over CaO. H2O and unreacted propionic acid were removed as their xylene azeotropes. It was vacuum dried. Material used as an electrolyte solvent (specific conductance less than 10 ohm cm" ) was obtained by fractional distn under reduced pressure, and stored over BaO or molecular sieves because it readily absorbs moisture from the atmosphere on prolonged storage.

Dissolve in Et20, add quinol (500mg for 300mL), dry over Na2S04, filter, evaporate and distil under dry N2. It is a clear liquid if dry and decompose very slowly. In the presence of H2O traces of tributyl tin hydroxide are formed in a few days. Store in sealed glass ampoules in small aliquots. It is estimated by reaction with aq NaOH when H2 is liberated. CARE stored samples may be under pressure due to liberated H2. [J Appl Chem 7 366 1957.]...
