Ghee is really a fat rich dairy product of Indian origin and it is western equivalent is butteroil. When ghee is stored under ambient temperature, it undergoes oxidative degeneration. The oxidation of unsaturated essential fatty acids produces hydroperoxides as well as their subsequent breakdown products viz. aldehydes, ketones, low molecular weight acids and oxy acids. These elements are accountable to add mass to off flavours in ghee. For more information on clarified butter , visit our website today!
The Meals Adulteration rules as amended in 1976 permit adding .02% by weight of butylated hydroxy anisole (BHA) and butylated hydroxy toluene (BHT) either singly or perhaps in combination to the ghee. The issue is the continual utilization of these antioxidants lead to teratogenic or cancer causing effect in small creatures and primates.
In ancient days, it had been a typical practice in India to include betel leaves and curry leaves towards the butter throughout the clarification procedure for ghee making. But it’s now recognized these substances indeed possess antioxidant qualities, that won’t only enhance the shelf existence and taste from the product but they are also safe towards the consumers.
A research was transported to read the antioxidant property of betel and curry leaves at different concentration when they’re steamed throughout the clarification procedure for ghee making. The findings reveal that the first peroxide worth of ghee (.00) demonstrated no increase as much as thirty days of storage at 30°C. However the control samples demonstrated a high rise in peroxide value after two months of storage. Ghee samples given 1% curry leaves were discovered to be probably the most resistant as much as 135 days. The betel leaves at 1% concentration made an appearance to become best and stable despite 147 times of storage at 30°C.
The quality of hydrolysis of ghee throughout the storage is measured by titration free of charge essential fatty acid (oleic acidity). Following a month storage, there’s a progressive rise in free essential fatty acid content. The control sample of ghee (not dealt with with any anti oxidant) demonstrated one hundred percent rise in free essential fatty acid content (after thirty days) while the betel leaves treated ghee (at 1% level) offered maximum protection towards the ghee from hydrolysis.
It’s observed the plant leaves (curry and betel leaves) contain phenolic compounds for example hydroxychavicol, eugenol, and certain proteins for example aspargine, glycine, serine, aspartic acidity, glutamic acidity, threonine, alanine, proline, and tryptophan that might possess antioxidant qualities and assist in improving the shelf existence of ghee.
A small decrease in the iodine value from 35.9 in charge to 35.6 in treated ghee samples is noted once the samples are stored at 30°C for 147 days. Ghee samples given chemical antioxidants demonstrated similar results. Ghee samples created with curry and betel leaves demonstrated a decreased butyrorefractometer (BR) studying. The compounds which go directly into solution throughout the clarification process might result in the decreased BR studying. Want to know more about what is ghee ?

To summarize, the betel and curry leaves may serve as a powerful antioxidant at 1% concentration with no adverse impact on the organoleptic qualities from the ghee which help switch the BHA and BHT to increase the shelf existence of ghee.
