Honey pigment

Peaches are quite susceptible to brown rot, caused by the fungus Mo-nilinia fructicola (Wint.) Honey. If the infection is not too severe, it can be controlled at about 200 krads. There appears to be a marked variation in varietal response. Some varieties retain relatively good quality while others show gross changes, particularly in texture. The anthocyanin pigment content in the flesh increases as a result of irradiation. Nectarines show a response to irradiation similar to that of peaches. 

In tests for melanophore pigment dispersion in eyestalkless individuals of the fiddler crab Uca pugilator, head extracts from the cockroach Periplaneta americana and the honey bee Apis mellifera showed strong activity, as did the crustacean eyestalk extracts 36). Head extracts of the butterfly Danaus plexippus and the mealworm Tenebrio molitor fere, however, inactive in the chromatophoral dispersion assay. 

Payakoff carried out the synthesis of various oxalate complexes by mechanical activation of the solid oxalic acid with hydroxides and basic salts [35], He demonstrated that the synthesis proceeded with the formation of honey-like mass from which solid complex crystal hydrates are crystallized relatively easily under aging of activating mixtures at room temperature. Ultrafine and highly reactive catalysts, pigments and other compounds of practical importance were obtained by thermal decomposition of the mentioned complexes.

The chemical composition of honey (Table 2.3) is dominated by glucose and fructose. Honey also contains many other valuable components, like enzymes, organic acids, mineral elements, nonprotein nitrogenous compounds, vitamins, aroma substances, and pigments. 

Corazonin, peptide amide from the corpora cardiaca (GG) of the American cockroach, Periplaneta americana. CC store and release neurohormones that are produced in neurosecretory cells of the CNS. Corazonin plays a role in molting, ecdysis, and adult development, and is implicated in circadian rhythm and diapause of insects. [His ]corazonin is capable of inducing dark pigmentation in an albino locust strain, while [Thr, His ]corazonin has been isolated from the honey bee Apis mellifera. Recent comprehensive peptide screening by mass spectrometry provides a general idea of the occurrence of corazonin forms in insects [R. Predel, Peptides 2007, 28, 3].

Honey or nectar guides are part of the pigmentation of many flowers, but these features are particularly common in bee flowers. 

Materials are essential to our life. It is hard to imagine how human civilization would have developed without stone, wood, clay, bronze, iron, brass, copper, and other kinds of stuff our tools and instmments are made of. Ohve oil and other vegetable oils, animal fats, wine and beer, honey and beeswax, juices and syrups, sea salt and rock salt, milk, and water have been used as food and medicines since prehistoric times. Materials are part and parcel of the material culture of human societies. Hence it is not surprising that they have served to demarcate large historical periods in human civilization, such as the Stone Age, Bronze Age, or Iron Age. Materials are even indispensable for the most accomplished forms of human hfe. There is no modern painting without canvas and pigments, no poem without paper and ink, no classical symphony without wood and metals to build the violin and the piano. 

Relatively little is known about honey color pigments. The amber color appears to originate from phenolic compounds and from products of the nonenzymic browning reactions between amino acids and fructose.
