Extraction, physicochemical, nutritive properties and fatty acid profile
of sweet cherry kernel oil
Abstract
Seed oils and nuts are frequently considered as waste products. During
fruit processing of the sweet cherry fruits into processed products the
seeds arise as a waste material in the food processing industries. The
seeds mainly composed of lipophilic compounds. Therefore, the present
work aimed to analyze the physico-chemical composition, nutritive
properties and volatile profile of sweet cherry kernel oil extracted by
Soxhlet extraction method through ethanol as asolvent which may be
useful for therapeutic purpose. It was observed that, the kernels oil
contains 57.75±2.70 mg/ml of proteins and 45.46 ±2.69 mg/ml of ascorbic
acid and 57.19±0.02mg/ml of tocopherol content. The sun protection
factor of oil was found 23.50 against UV-B rays. The key fatty acids
present in sweet cherry seed oil (SCSO) was oleic acid (21%), palmitic
acid (6.2%), linoleic acid (5.6%) and steric acid (4.3%)
respectively. The volatile organic compounds were identified by Gas
Chromatography and Mass Spectroscopy (GC-MS) and the highest contents of
volatile compounds belong to the category of carboxylic acid, alkanes,
alkenes and alcohols. In that Squalene (26.71%), Oleic acid (6.64 %),
and Linoleic acid (4.32%) were most abundantly present. The present
study showed that oil of cherry seeds usually thrown as waste has high
content of vitamin c, tocopherol and various secondary metabolites.
Also, the oil comprises presence of vital fatty acid so that it can be
use in food industry as well as in therapeutic application.
