Processing stability and debittering of Tinospora cordifolia (giloy) juice using ultrasonication for potential application in foods

Abstract: Herbal plants have been used as medicines since time immemorial. T. cordifolia (giloy) is one such medicinal plant that possesses many therapeutic properties. Certain challenges such as thermal stability and bitter taste (diterpenoids, lactones), calls for technological interventions for effective debittering and retention of its bioactivity. This study was aimed at the removal of bitterness in giloy samples along with the evaluation of their processing stability at three different temperatures (72 °C/16 s; 100 °C/10 min; 121 °C/15 min). Membrane processing technique and addition of β-cyclodextrin, a polysaccharide derivative (PD), as a debittering compound, singly or in combination, did not produce desirable results. Several approaches were adopted to remove bitterness using herbal extract (0.1 g/100 g stems), and PD (3 g/100 mL juice) combined with magnetic stirring, thermosonication, and ultrasonication. Results revealed that ultrasonication could eliminate the bitterness, below the detection limits, in giloy juice at 10 min duration with retention of most of the bioactive components and antioxidant activity. The results suggest that ultrasonication could help in debittering extracts of other herbal plants as well. Besides, food industries may develop sensorially acceptable giloy based functional beverages with longer shelf-life, thus broadening the field of industrial application.

Productive and Reproductive Performance of Buffalo

Abstract: The present study was carried out drawing a sample of 120 dairy farmers using random sampling from the three blocks of Unnao district of Uttar Pradesh and from each block two villages were selected randomly. Production and Reproduction is one of the most important considerations to determine the profitability of buffalo. The parameters of productive and reproductive performance of buffalo were as under: Average daily milk yield, 5.36±1.2 lit./day/buffalo, lactation length, 293.5±27.1 days/buffalo, lactation milk yield, 1636.4±189 lit./buffalo, peak yield, 8.1±1.9 lit./buffalo, dry period, 156.4±39.6 days/buffalo, Age at first calving, 1482±162 days/buffalo, Service period, 142±26 days/buffalo, Service per Conception, 2.57±0.45 times/buffalo and Calving interval was 450.2±35.1 days/buffalo. The results showed that dry period and service period were found to be high which resulted in increase in inter-calving period, thereby leading to the increase in unproductive period among buffaloes of the study area.

Fatty acid profile of unconventional oilseeds.

Abstract: The continued increase in human population has resulted in the rise in the demand as well as the price of edible oils, leading to the search for alternative unconventional sources of oils, particularly in the developing countries. There are hundreds of un- or underexplored plant seeds rich in oil suitable for edible or industrial purposes. Many of them are rich in polyunsaturated essential fatty acids, which establish their utility as “healthy oils.” Some agrowaste products such as rice bran have gained importance as a potential source of edible oil. Genetic modification has paved the way for increasing the oil yields and improving the fatty acid profiles of traditional as well as unconventional oilseeds. Single cell oils are also novel sources of edible oil. Some of these unconventional oils may have excellent potential for medicinal and therapeutic uses, even if their low oil contents do not promote commercial production as edible oils.
