Preparation of food supplements from oilseed cakes

Abstract

Oilseed cakes have been in use for feed preparation. Being rich in proteins, antioxidants, fibers, vitamins and minerals, oilseed cakes have been considered ideal for food supplementation. These oilseed cakes can be processed and made more palatable and edible by suitable treatments and then incorporated as food supplements for human consumption. Rice bran pellets (RBP), stabilized rice bran (SRB), coconut cake (CC) and sesame cake (SC) were taken up for the study. These were mixed with distilled water and cooked in such a way to separate the cooked solid residue and liquid extract followed by freeze drying to get two products from each. The raw, cooked dried residue and extract were analyzed for various parameters such as moisture (0.9-27.4 %), fat (2.1-16.1 %), ash (3.3-9.0 %), minerals (2.6-633.2 mg/100 g), total dietary fiber (23.2-58.2 %), crude fiber (2.7-10.5 %), protein (3.2-34.0 %), and the fat further analyzed for fatty acid composition, oryzanol (138-258 mg/100 g) and lignan (99-113 mg/100 g) contents and also evaluated sensory evaluation. Nutritional composition of products as affected by cooking was studied. The cooked products (residue and extract) showed changes in nutrients content and composition from that of the starting cakes and raw materials, but retained more nutrients in cooked residue than in the extract. The sensory evaluation of cooked residue and extract showed overall higher acceptability by the panelists than the starting cakes and raw materials. On the basis of these findings it can be concluded that these cooked residue and extract products are highly valuable for food supplementation than the raw ones.

Development of Health Foods from Oilseed Cakes

“…Dietary fibers are best known for its ability to prevent or relieve constipation. The total dietary fibers were ranged from 32.35 to 55.8% and these values were agreed well with those reported for the total dietary fiber of copra and sesame cakes [2]. The soluble and insoluble fibers were ranged from 2.8-4.1 and 28.2-52.2 respectively.…”

“…Cooked solid residues of copra cake and sesame cakes were used as ingredients for the preparation of health foods [2].…”

“…The oilseed cakes have been mainly used for feeding cattle and these oilseed cakes are rich in nutrients like proteins, carbohydrates, antioxidants, vitamins and minerals. These oilseed cakes can also be used for human consumption for proper processing and preparation of low-cost health foods [1,2]. Oilseed cakes are of two types, edible and non-edible grades.…”

“…Copra cake has been used for feeding cattle since it is rich in nutrients like protein, fat, nutraceuticals, fibers, vitamins and minerals. The copra cake can be processed and made edible for human consumption by giving certain treatments since it can be used as valueadded products in food industries [2]. Coconut water solids may be prepared by drying the tender coconut water, which can be preserved for a longer time and is nutritionally rich in minerals especially sodium and potassium.…”

Graphene and Graphene‐Based Materials in Biomedical Science

“…Compounds utilized as antimicrobial agents are extensively applied in fields like industries, synthetic textiles, food, environment, packaging, medical care products, and health care . Contamination is major concern and the contamination of food due to the spoilage and microbial growth constitutes a major public health concern and economic burden on the food industry . Nanotechnology, by the use of nanomaterials and their composites, can help in developing potent antimicrobial agent to be used in preventing the contamination of food products, in packaging, and storage applications.…”
