Effect of physicochemical properties on popping characteristics of selected pearl millet varieties.

Background: Pearl millet, commonly known as 'Bajra', is a nutrigrain, mostly used in pulverized form to make unleavened pancakes, dumplings, porridge, etc., in India. Popping, a traditional method of millet processing, is used in making ready-to-eat snacks.

A novel method for double encapsulation of C-phycocyanin using aqueous two phase systems for extension of shelf life.

is having high nutritive value due to pigments such as chlorophyll-a, phycobiliproteins (especially phycocyanins) and carotenoids. In our present work, C-phycocyanin (C-PC) was extracted from dry biomass of . C-PC being heat sensitive, reiterates the need for additional protection during drying (micro encapsulation).

Design and development of a machine for continuous popping and puffing of grains.

Popping/puffing have been traditionally practiced for enhancing storage life, improving organoleptic properties and ease of incorporation in ready-to-eat-foods. Currently, batch type sand and electric popping/puffing machines involving conduction mode of heat transfer are employed. The major drawbacks of these methods are high-energy consumption, scorching of grains, non-uniform product quality, contamination (by sand/ash) and problems in scale-up.

Recovery of chlorophylls from spent biomass of Arthrospira platensis obtained after extraction of phycobiliproteins.

Extraction of chlorophylls has received scant attention or priority over phycobiliproteins from Arthrospira platensis. In fact extraction of chlorophylls from spent biomass (left after extraction of phycobiliproteins which goes as waste or underutilized) on drying, will improve the economics of the overall downstream processing. Ethanol (yield 5.

Ultrasound assisted methods for enhanced extraction of phycobiliproteins from marine macro-algae, Gelidium pusillum (Rhodophyta).

Extraction of phycobiliproteins (R-phycoerythrin, R-PE and R-phycocyanin, R-PC) from macro-algae is difficult due to the presence of large polysaccharides (agar, cellulose etc.) present in the cell wall which offer major hindrance for cell disruption. The present study is aimed at developing most suitable methodology for the primary extraction of R-PE and R-PC from marine macro-algae, Gelidium pusillum(Stackhouse) Le Jolis.

Development of a lemon cutting machine.

Cutting of lemon and other similar fruits is conventionally done manually by sharp knife, which is labor intensive and often un-hygienic. In the present work, a device has been designed and developed for cutting of lemon hygienically into four pieces of similar shape based on stationery cutters and rotating centralizing/locating slit plate concept. Machine has a unique knife assembly consisting of two bird wing shaped knives, joined by welding perpendicularly to a vertical knife, so that the lemon can be cut into four pieces in a single sweep.
