Effect of storage on PHYSIO-CHEMICAL EVALUATION OF PEANUT YOGURT Effect of storage on peanut yogurt

ABSTRACT: Peanuts may be consumed in a variety of processed forms like roasted, raw and processed etc. And represent as a multimillion dollar crop worldwide with many potential dietary benefits as it contains high protein and health effective oils. Objective: The present investigation was planned to evaluate thephysio-chemical properties of peanut milk yogurt by the addition of different concentration of peanut milk (0 %, 10 %, 20 % and 30 %), skimmed milk liquid (60 %, 70 %, 80 %, and 90 %), skimmed milk powder (9 %) and sugar (1 %). Methods: The physico-chemical tests (pH, acidity, moisture, ash, fat, protein, syneresis, and viscosity) were examined after every 5 days of interval for a period of 15 days at 4 ºC. Results: The results of physico-chemical analysis revealed that pH, ash, fat, protein and viscosity decrease during storage period where as acidity, moisture and rate of syneresis increased during storage. Treatment T1 (10 % peanut milk) was comparatively best for manufacturing of peanut milk yogurt followed by T2 (20 % peanut milk + 70 % skimmed milk liquid + 9 % skimmed milk powder + 1 % sugar) while peanut milk yogurt from (30 % peanut milk + 60 % skimmed milk liquid + 9 % skimmed milk powder + 1 % sugar) had the lowest degree of firmness. Conclusions: It was noticed that correlation among fat, total solids and protein contents in peanut milk affect the extent of serum separation and pH of yogurt. The storage had significant effects on all physico-chemical parameters. Treatments had significant effect on all physico-chemical parameters

Combinatorial and Arithmetic Study of Binomial Edge Ideal

Let J G denote the binomial edge ideal of a connected undirected graph G on n vertices. This is the ideal generated by the binomials x i y j −x j y i , 1 ≤ i < j ≤ n, in the polynomial ring S = K[x 1 , . . . , x n , y 1 , . . . , y n ] where {i, j} is an edge of G. Our aim in this thesis is to compute certain algebraic invariants like dimension, depth, system of parameters, regular sequence, Hilbert series and multiplicity of J G of some particular classes of binomial edge ideals of graphs. A large amount of information of an ideal is carried by its minimal free resolution. So we give information on the minimal free resolution on certain binomial edge ideals. We also give a complete description of the structure of the modules of deficiencies of binomial edge ideals of some classes of graphs. A generalization of the concept of a Cohen-Macaulay ring was introduced by S. Goto [7] under the name approximately Cohen-Macaulay. In this thesis we collect a few graphs G such that the associated ring S/J G is approximately Cohen-Macaulay. We also characterize all the trees that are approximately Cohen-Macaulay. As more generalized notion than approximately Cohen-Macaulay we also study se- quentially Cohen-Macaulay property for binomial edge ideals. We give a nice con- struction principle in this topic. ̃ on n vertices has the property that S/J̃ is a Cohen-Macaulay The complete graph G G domain with a 1-linear resolution. As one of the main results we clarify the structure of S/J K m,n , where K m,n denotes the complete bipartite graph.
