Peach

HCOOCHjCHj. Colourless liquid with the odour of peach-kernels b.p. 54 C, Prepared by boiling ethanol and methanoic acid in the presence of a little sulphuric acid the product is diluted with water and the insoluble ester separated and distilled. Used as a fumigant and larvicide for dried fruits, tobacco and foodstuffs. It is also used in the synthesis of aldehydes.

Potassium nitrate is being used increasingly on intensive crops such as tomatoes, potatoes, tobacco, leafy vegetables, citms, and peaches. The properties that make it particularly desirable for these crops are low salt index, nitrate nitrogen, favorable N K20 ratio, negligible CU content, and alkaline residual reaction in the soil. The low hygroscopicity of KNO (Table 9) leads to its use in direct appHcation and in mixtures. It is an excellent fertilizer but the high cost of production limits its use to specialty fertilizers. 

There are two methods available for aroma recovery. In one method, a portion of the water is stripped from the juice prior to concentration and fractionally distilled to recover a concentrated aqueous essence solution. Apple juice requires 10% water removal, peach 40%, and Concord grape 25—30% to remove volatile flavor as an essence. Fractional distillation affords an aqueous essence flavor solution of 100—200-fold strength, which means the essence is 100 to 200 times more concentrated in flavor than the starting juice. A second method of essence recovery is to condensate the volatiles from the last effect of the evaporator they are enriched in volatile flavor components (18).

Lactidichlor-ethyl has been used to increase yields, reduce fmit drop in apples, and increase maturity in grapes. It causes fmit drop in peaches which decreases actual number of peaches per tree while increasing yields due to larger fmit size. The mode of action is attributed to inhibition of ethylene... 

Plants. AsexuaHy reproducing plants, ie, those not propagated by means of seed, also represent a legally recognized class of patentable subject matter under U.S. patent laws. Additionally, the inventor must have discovered and asexuaHy reproduced the plant that is to be the subject of the patent apphcation. Plant patents are assigned a different series of numbers than the majority of patents discussed in the foregoing, such as U.S. Plant Patent No. 3,360 titled "Peach Tree" (7). 

Sorbate combined with mild heat has a synergistic effect with regard to microbial destmction thus, in the presence of 0.025—0.06 wt % sorbate, products such as apple juice, peach and banana sHces, fmit salads, and strawberries can be treated with less severe heat treatments to extend shelf life (119,120). Sorbates increase the heat sensitivity of various spoilage fungi under varying conditions of pH and water activity (121—124). A similar synergistic effect has been reported for the combination of sorbate with irradiation (125). 

The other significant production method for natural benzaldehyde involves the steam distillation of bitter almond oil which has been derived from the kernels of fmit such as apricots, peaches, cherries, plums, or pmnes. The benzaldehyde product obtained in this fashion is claimed to have a superior flavor profile. The use of peach and apricot pits to produce the more profitable product laettile apparently affects the supply available to natural benzaldehyde producers. 

Softer metals such as aluminum and its alloys can be blast cleaned using abrasives that are not as hard as those used on steel. Garnet, walnut shells, corncobs, peach pits, glass or plastic beads, and soHd carbon dioxide have been used successfully. 

Benzaldehyde Cyanohydrin. This cyanohydrin, also known as mandelonitrile [532-28-5] is a yellow, oily Hquid, insoluble in water, but soluble in alcohol and diethyl ether. Mandelonitrile is a component of the glycoside amygdalin [29883-15-6] a precursor of laetdle [1332-94-7] found in the leaves and seeds on most Prunus species (plum, peach, apricot, etc). In 1832, mandelonitrile was the first cyanohydrin to be synthesized. 

In a recent study for the US Department of Energy [61], AGLARG have shown that suitable adsorbents for ANG can be produced from peach pit or coconut shell using KOH as the activating agent. These carbons, like all KOH produced carbons, were low in bulk density. Densities of greater than 0.6 g/ml were possible with compaction in small vessels (<50 ml) and deliveries of greater than 150 V/V methane could be obtained from 3.4 MPa at 298 K.
