Development of Fruit Yoghurt Incorporated with Jak (Artocarpus Heterophyllus L.) and Evaluation of its Physicochemical, Microbiological and Sensory Properties
Pilapitiya, O.H; Jayamanne, V.S
Yoghurt is manufactured by curdling of milk with purified cultures of two yoghurt bacteria
such as Lactobacillus bulgaricus and Streptococcus thermophilus that ferment the milk sugar
(lactose) into lactic acid. Fruit yoghurts are becoming popular in the world due to their
different flavours, tastes as well as high nutritional properties. Jak (Artocarpus heterophyllus
L.) is an underutilized fruit species in Sri Lanka and its uses are yet to be explored. The
objectives of this study were to develop' a value-added yoghurt with Jak fruit and to evaluate
its sensory, physicochemical and microbiological properties. Four different types Jak fruit
yoghurts were produced in the laboratory such as plain set yoghurt (control), yoghurt with
candied Jak fruit with jelly as the top layer, yoghurt with fresh Jak fruit and yoghurt with fresh
Jak fruit with jelly as the top layer. Sensory attributes such as appearance, taste, texture,
aroma and overall acceptability of novel fruit yoghurts were evaluated after manufacture of
yoghurts. The titratable acidity and pH of Jak fruit yoghurts were also determined on l si, 5th,
7th, 10th, 12th, 15th and 17th days after manufacture. Completely Randomized Design (CRD)
was used as the experimental design. Sensory evaluation results were analyzed using Kruskal-Wallis non-parametric One-Way ANOVA test with STATISTIX computer package (Ver 2.0)
for windows. Results of sensory evaluation revealed that yoghurts which contained fresh Jak
fruit with top layered jelly mix had significantly higher (PO.OS) sensory properties.
Microbiological analysis revealed that three new yoghurt products were free of E. coli and
yeast and mold. Furthermore, physicochemical analysis of the new fruit yoghurts revealed
that they are acceptable in terms of their nutritive quality with 3.5% fat and 23% Total Solid
(TS) contents. The results of the present study suggest that high quality Jak fruit yoghurts can
be produced by adding both fresh and candied Jak fruit with jelly mix as the top layer of the
set yoghurt. This new product will help to utilize seasonal Jak fruit to a considerable extent.

Impact of Employer Authoritarianism on Employee Needs Achievement: With Special Reference to Harischandra Mills Pic
Priyadarshani, S.A.S; Abeywickrama, H.V.D.I
Like people, organizations have personalities, but the traits or dimensions are not necessarily
the same because of the differences between organizations and people. The organizational
personality trait that is most relevant to organizations is authoritarianism. Authoritarianism
which is one of five organizational personality traits is important to employers due to
employee need achievement which is one of organizational performance outcomes have been
associated with them. This study investigates the nature and extent of employer
authoritarianism on employee needs achievement. The main focus of the study is to examine
the impact of employer authoritarianism on employee needs achievement by giving the special
priority to Harischandra Mills PLC; manufacturing company in Matara. Survey method was
used as the main research method for the study and the sample consisted of 100 employees of
the company. Sample was selected on systematical basis among employees of seven (07) key
functions of the company. Data for the study was collected using a self-administered
questionnaire and depth interviews. Questionnaire was developed mainly considering on
variables of authoritarianism which included in organizational personality traits structure and %
dimensions of employee needs achievement (Maslow’s Hierarchy of Needs).The correlation
matrix was constructed to explore whether there are significant relationship between the
variables of employer authoritarianism and dimensions of employee needs achievement.
Spearman’s who was used to measure the significant of the relationships of each variables at
two levels (0.05 and 0.01).Cronbach’s alpha was used to evaluate the reliability of the study
measures used. Survey results revealed that employer authoritarianism exert a significant
positive impact on employee needs achievement.
