India being the leading producer, consumer and second largest exporter of cashew in the world, has a prime position in cashew trade in the world market. But the productivity level of Indian cashew is far less than that of its close competitors viz., Vietnam, Nigeria, Cote de‟Ivoire, Philippines etc. The cashew processing sector in India is
one of the largest in the world and has given huge employment to rural people especially
the women folk. Some of the cashews processing industries in India are still under unorganized sector. Increasing demand for the nuts has necessitated the increased production. The present review is an attempt made towards understanding the Indian cashew industry in relation to its position in the global market, problems being faced by the cashew industry and the scope in future.

The study revealed that maximum TSS (7.73 ºBrix), chlorophyll- a (1.82 mg g-1), chlorophyll- b (0.54 mg g-1), total chlorophyll (2.36 mg g-1), reducing sugar (5.29 %), non-reducing sugar (1.16 %), total sugar (6.45 %), ascorbic acid (54.80 mg/100 g), sugar to acid ratio (6.58) and minimum titratable acidity (0.98 %) recorded in the media combination having soil + cocopeat + vermicompost in the ratio of 1:1:1 on volume (v/v) basis. Also, the same media combination increased the TSS and ascorbic acid by 28.19 and 7.16 per cent over the control, respectively.

The fruit rinds extracts were examined to evaluate the antimicrobial activity against 3 Gram-positive Bacteria i.e. Bacillus subtilis and Staphylococcus aureus and Enterococcus fecalis, 2 Gram-negative bacteria Escherichia coli and Shigella boydii, using Agar well diffusion antimicrobial assay. The zone of inhibition was nil at the concentration of 1g/100ml. However the minimum zone of inhibition was found at the concentration rate of 10g/100ml in Enterococcus fecalis (13.59mm), Shigella (12.89mm), Bacillus subtilis (12.69mm), Escherichia coli (11.68mm) and Staphylococcus aureus (9.75mm) respectively. Since the extracts showed a broad spectrum of antimicrobial activity on both gram positive and negative bacterial isolates, Garcinia gummigutta can be used as a bio preservative or neutraceuticals or therapeutic agent to prevent several diseases.

Obesity (BMI ≥ 30 kg/m 2) is associated with several chronic and debilitating health problems including hyperlipidemia, hypertension, coronary heart disease, diabetes, cancer and disease of the gall bladder, osteoarthritis, shortage of breath, abnormal dilation of the veins, backache, and even psychological problems. A wide variety of weight management strategies are presently available, and some involve the use of dietary supplements which are marketed as slimming aids. One such slimming aid is Garcinia gummi-gutta. It is rich in one principal component to reduce obesity and cholesterol level i.e. (-)-Hydroxy citric acid (HCA). HCA is a derivative of citric acid and is found in Garcinia gummi-gutta and Garcinia indica. HCA also being reported to increase the release or availability of serotonin in the brain, thereby leading to appetite suppression by reducing carbohydrate metabolism. Hence Malabar Tamarind can be exploited for its commercial use in various value added products to maintain general health of the public.

The bio active components such as total flavanoids were analysed by Aluminium chloride colorimetric method, total tannins by Ferri cyanide and ferric chloride colorimetric method and total poly phenols by Folin ciocalteu's reagent method respectively. Antioxidant activity of Garcinia gummigutta fresh and dry rinds were determined using DPPH scavenging activity by taking Gallic acid as the standard. The bio active components were high in fresh rind i.e total flavanoids, w/w 2.48 (per cent), total tannins, w/w 2.76 (per cent) and total poly phenols, w/w 1.1 (per cent) than in dry rind 0.20 (per cent), 0.10 (per cent) and 0.04(per cent) respectively. The antioxidant activity of fresh rind was 66.30 (per cent), 73.65 (per cent) and 81.44 (per cent) at the dose of 20mg, 40mg and 60mg. Hence, the traditionally claimed medicinal benefits of gummigutta might be due to its potential antioxidant property. However, further studies to be carried out on animal models using their biological tissues before exploiting commercially.
