Minimum inhibitory concentrations (MICs) and minimum fungicidal concentrations (MFCs) were determined for 38 oils of plant origin against Candida albicans. Four strains including one standard strain were used in this study. The antifungal agents, Fluconazole and Amphotericin B were used as positive controls. The standard strain (ATCC10231) used in this study was found to be highly resistant to Fluconazole: 3000 microg ml(-1) of Fluconazole was required to inhibit the growth of this strain partially, and complete inhibition could not be achieved. Other Candida strains were sensitive to 5 microg ml(-1) of Fluconazole. All the strains used were sensitive to Amphotericin B. Of the 38 oils tested, 23 were found effective and fifteen were ineffective. Based on their MFCs, effective oils were categorized into three categories. Seven oils, which exerted fungicidal effect at less than 0.15% concentration of oils, were grouped into the most effective class. The oils exhibiting MFCs in the range of 0.16-1.5% concentration were considered moderately effective. Nine oils, which required more than 1.5% concentration, were regarded as less effective. The Fluconazole-resistant strain (MTCC 227) was sensitive to at least 23 of the plant oils. Results of this study indicate that oils of plant origin may find use as potential anti-Candida agents.
Goat milk is considered to be a potential source of various macro- and micro-nutrients. It contains a good proportion of protein, fat, carbohydrates, and other nutritional components which help in promoting nutritional and desirable health benefits. Goat milk is considered to be superior in terms of numerous health benefits, and lower risk of allergy, when compared to the milk of other species. Several processing techniques such as pasteurization, ultrafiltration, microfiltration, and ultrasound have been employed to enhance the quality and shelf life of goat milk and its products. The diverse range of goat milk-based products such as yogurt, cheese, fermented milk, goat milk powder, and others are available in the market and are prepared by the intervention of advanced processing technologies. Goats raised in pasture-based feeding systems are shown to have a better milk nutritional composition than its counterpart. Goat milk contains potential bioactive components, which aids in the maintenance of the proper metabolism and functioning of the human body. This review gives insight into the key nutritional ingredients and bioactive constituents present in goat milk and their potential role in the development of various functional foods using different processing technologies. Goat milk could be considered as a significant option for milk consumption in infants, as compared to other milk available.
Purpose Noodles are good vehicles for the enrichment and can be enriched with vegetable purees. However, this enrichment can alter quality attributes of noodles with resultant effect on its sensorial attributes. The purpose of this paper is to study the effect of addition of different hydrocolloids on the microstructural and quality characteristics of instant noodles enriched with spinach puree. Design/methodology/approach Preliminary trials were carried out for the standardization level of addition of spinach puree in noodle formulation. Carboxymethyl cellulose (CMC) and guar gum were added in the noodle formulation at 0.25, 0.5 and 0.75 per cent level of incorporation. The effect of addition of hydrocolloids was evaluated on the cooking quality, sensory attributes, texture characteristics and microstructure of the noodles. Findings The most acceptable ratio for the formulation of the noodles was found to be 40 g spinach puree per 100 g refined wheat flour. Addition of hydrocolloids resulted in the increase in the cooking time, cooking weight, water absorption and swelling index. Significant decrease in the cooking loss was observed with the increase in the level of CMC (from 7.4 to 6.1 per cent) and guar gum (from 7.4 to 7 per cent). Addition of CMC and guar gum up to 0.5 per cent and 0.25 per cent, respectively, improved the texture, overall acceptability and mouthfeel attributing to complimentary interaction between starch, fibre and hydrocolloids observed at microstructural level; however, further increase in the level of incorporation resulted in stickiness and sliminess in the noodle strands. Practical implications It is found that 0.5 per cent CMC and 0.25 per cent guar gum can be used for the enhancement of quality characteristics of the spinach puree enriched noodles. Originality/value Intervention of incorporation of hydrocolloids in spinach puree–enriched instant noodles delivers healthy and nutritious product without compromising on its sensorial and quality attributes.
The present investigation was undertaken to develop carrot puree‐incorporated noodles and increase vegetable intake in the diet of consumers. Carrot puree was incorporated at 0, 10, 20, 30, 40, and 50 g per 100 g of refined wheat flour. Cold extrusion and air‐drying method were used to prepare noodles. Carrot noodles were analyzed for nutritional, sensory, cooking, and textural properties. Forty grams of vegetable puree per 100 g of refined wheat flour was preferred in sensory evaluation. The nutritional analysis results of 100 g dried carrot noodles indicated increase in total carotenoids (1.58 mg) and minerals such as calcium (36.3 mg), phosphorous (140.4 mg), iron (9.5 mg), potassium (192.4 mg), and crude fiber (3.85 g) compared with control. Carrot noodles in comparison with control (14.33%) showed decreased cooking loss (8.74%) which affirmed better binding of fiber particles with starch–protein matrix. The texture analysis of test noodles showed reduction in hardness (27.06%), springiness (79.78%), and cohesiveness values (0.74%) compared with control noodles. Practical Applications Instant noodle enrichment with vegetable source (carrot) will not only find a new avenue for the noodle industry to provide healthier option to the consumers but also nutritionally enhance the noodles with micronutrients such as vitamins, minerals, dietary fibers, and phytochemicals. The carrot in puree incorporation improves the sensory, cooking, and nutritional qualities of noodles. The enrichment with vegetable source (carrot) will develop low‐energy dense air‐dried instant noodles and can help increase vegetable intake in the diet of consumers through a food matrix that is well appreciated by all age groups.
