In the present study, development of electrolyte drinks from paneer and cheese whey was carried out by enzymatic hydrolysis of lactose to simple sugars and formulating the sugar to salt ratio to meet the World Health Organization (WHO) requirements (245 mOsmol/L) for Oral Rehydration Salt (ORS). Lactose hydrolyzed whey was diluted (1: 2.3 v/v) using potable quality demineralised water to achieve reduction in osmolarity of 75 mOsmol/L. The salt concentration was adjusted by adding 3.25 g sodium chloride and 0.8 g potassium chloride for paneer whey (per L) and 2.5 g sodium chloride, 0.9 g of potassium chloride and 1.5 g of trisodium citrate for cheese whey (per L) to meet Na, K and citrate levels in the resultant whey drink as per WHO requirement. Other additives used in developing hypotonic electrolyte whey drink from lactose hydrolyzed whey systems were sucralose (sweetener), citric acid (acidulant), orange flavour and orange colour. The formulated hypotonic electrolyte whey based drink had significantly higher sensory scores when compared to the scores of two commercial orange flavour ORS drinks. Cheese whey based electrolyte drink was superior over paneer whey based electrolyte drink in sensory characteristics; former drink had better consistency and mouth feel.

The North American stalked puffball Calostoma cinnabarinum (Boletales) owes its red-orange colour to the heptaene pigment calostomal. Its structure has been determined by 1H and 13C NMR spectroscopy of the corresponding methyl ester as all-trans-16-oxohexadeca-2,4,6,8,10,12,14- heptaenoic acid (1). Neither pulvinic acids nor other typical Boletales pigments could be detected in this fungus. The structural relationship of 1 to other polyene pigments from fungi is discussed.

In 1867 I made some experiments on the action of sodium upon chinoline and lepidine, and found that a substance was produced which dyed silk a beautiful but fugitive orange colour. I announced this fact in a paper “ On the Higher Homologues of Chinoline.

Understanding the causes of variation in feather colour in free-living migratory birds has been challenging owing to our inability to track individuals during the moulting period when colours are acquired. Using stable-hydrogen isotopes to estimate moulting locality, we show that the carotenoid-based yellow–orange colour of American redstart ( Setophaga ruticilla ) tail feathers sampled on the wintering grounds in Central America and the Caribbean is related to the location where feathers were grown the previous season across North America. Males that moulted at southerly latitudes were more likely to grow yellowish feathers compared with males that moulted more orange–red feathers further north. Independent samples obtained on both the breeding and the wintering grounds showed that red chroma—an index of carotenoid content—was not related to the mean daily feather growth rate, suggesting that condition during moult did not influence feather colour. Thus, our results support the hypothesis that feather colour is influenced by ecological conditions at the locations where the birds moulted. We suggest that these colour signals may be influenced by geographical variation in diet related to the availability of carotenoids.

Zeaxanthin is a dietary carotenoid accumulated in the macula in order to reduce photoreceptor oxidation by blue light. Damage caused to photoreceptor cells in the human eye leads to macular degeneration, which is the leading cause of blindness in developed countries. Zeaxanthin, an orange pigment, is rarer in western diets as compared to the yellow pigment, lutein, the other important macular carotenoid. Orange capsicums (Capsicum annuum) have been reported to be an excellent source of zeaxanthin, but there are limited reports about its occurrence both within, and in other closely related species (C. baccatum, C. chinense). In the current investigation, yellow, orange and red coloured accessions of C. annuum, C. chinense and C. baccatum were analysed for their carotenoid profiles to identify high zeaxanthin accessions. A carotenoid extraction protocol and ultra-high-performance liquid chromatography-photometric diode array-mass spectrometry (UHPLC-PDA-MS) analysis was optimised to identify and quantify carotenoids in the capsicum accessions both before and after saponification. Interestingly, out of 22 varieties tested, only the ‘Orange Belle’ orange capsicum demonstrated a high accumulation of zeaxanthin. Other accessions exhibiting orange colour accumulated different orange carotenoid pigments to zeaxanthin, such as violaxanthin, beta-carotene, and beta-cryptoxanthin. Yellow coloured accessions accumulated a high concentration of lutein or alpha-carotene, while red cultivars were highest in capsanthin and capsorubin. The present findings suggests a need for further studies to identify high zeaxanthin germplasm which can be cross-bred with orange capsicums for future biofortification, in order to help increase the daily dietary intake of zeaxanthin in western diets.

Exæretopus caricis, n. sp.Adult ♀ salmon pink, shiny, about 2 mm. long and 1 mm. broad, elongage oval. Legs and antennæ light brown. ♀ secretes a mass of cotton all over her body, becoming so dense as to completely envelope the entire body, looking more like and elongated Eriococcus. This secretion extends caudad, forming a large egg-sac, which, including the whole insect, measures from 4 to 5 mm. Eggs salmon pink. Yound larvæ orange colour. Adult ♀ after boiling in K.O.H.derm remains light brown. Margin beset with fine, short, straight spines, incisions having two stout curved spines. There are numerous short conical spines scatterd over the derm with irregular rows of long fine hairs. Anal plates large and thick, each with four shor, stout spines. Anal ring with six very long, stout hairs, which extend to caudal end of plates. Antennæ long, slender, tapering, 8-jonted. Joint 3 always longest and joint 7 always shortet, each joint with one or more fine hairs, joint 8 with several long hairs.

Oberonia aureolabris sp. nov. from western Java is described, having been studied using light and scanning electron microscopy. It is distinguished by a panduriform inflated disc, relatively short and widely separated epichile lobes on the lip, more or less equal length of the floral bracts over the entire floriferous portion of the inflorescence and orange colour.

Leptogorgia ignita is a new gorgonian species characterized by its conspicuous bright orange colour, irregular branching pattern and combination of sclerite types in the coenenchyme, all of the same orange colour, with abundance of capstans and blunt spindles, and less abundant acute spindles. The species was found in a shallow water coral community, 4–12 m deep in Samara Bay, Pacific Costa Rica. Morphologically, L. ignita belongs to the L. rigida-group comprising eight species for the group; 13 Leptogorgia species are known for Costa Rica, and 23 for the entire eastern Pacific. The new species is described, illustrated and compared to the other valid taxa of the group.
