    Abstract The inlet air temperature and feed flow rate of a spray drying process were optimized for encapsulation of Lactobacillus acidophilus ATCC 11975 using a ternary wall matrix of skim milk powder, maltodextrin, and cellulose acetate phthalate. The combined effect of inlet air temperature (140, 150, and 160℃) and feed flow rate (2.0, 2.5, and 3.0 ml/min) was studied on the encapsulation efficiency (EE), survival rate (SR), moisture content (MC), recovery yield (RY), and water activity (aw) by creating response surface plots in a full factorial design. A significant (p < .05) decrease in EE, SR, MC and aw, and increase in RY values of the powder were noticed by increasing the temperature and decreasing the feed rate. The optimum conditions to produce maximally viable probiotic powder were 145℃ and 2 ml/min. The shape of the particles was spherical. Thermal characterization revealed a better storage stability with a low inactivation rate. PRACTICAL APPLICATIONS: Achieving a higher survival rate of probiotics to confer adequate health benefits to human gut is the prime concern of this research which was successfully achieved by optimizing the spray drying parameters. This manuscript details the potential application of a ternary wall matrix composite consisting of skim milk powder, maltodextrin, and cellulose acetate phthalate to successfully encapsulate the probiotic strain of Lactobacillus acidophilus, with improved encapsulation properties. The study will help towards formulating a novel dairy‐based probiotic food with enhanced gut microbiota by generating the necessary background data required.

  2. Article: Microencapsulation of ghee flavorants with whey protein concentrate and guar gum using spray drying

    Abstract: Microencapsulation of ghee flavor extract (GFE) using emulsions of whey protein concentrate (WPC‐80) (15% to 22% w/w) and guar gum (GG) (0.1% to 0.5% w/w) was investigated upon spray drying to produce low fat and cholesterol‐free ghee flavor enriched ... ...

    Abstract Microencapsulation of ghee flavor extract (GFE) using emulsions of whey protein concentrate (WPC‐80) (15% to 22% w/w) and guar gum (GG) (0.1% to 0.5% w/w) was investigated upon spray drying to produce low fat and cholesterol‐free ghee flavor enriched powder. The effectiveness of the encapsulation was analyzed in terms of encapsulation efficiency (EE), solubility index (SI), and flavor retention (FR) of the encapsulated ghee flavorants. An emulsion with a combination of 15% GFE, 15.76% WPC‐80, and 0.1% GG could achieve the maximum EE (53.2%), SI (81.464%), and FR of δ‐dodecalactone (66.38%) and δ‐tetradecalactone (78.33%). The mean particle size of the powder was 124.4 nm with a span value of 0.945. The Carr's index (CI) and Hausner ratio (HR) of the powder were 17.65% and 1.21, respectively, suggesting that the powder had good flowability. The microparticles were spherical and the glass transition temperature value ranged from 247.8 to 249.4°C. PRACTICAL APPLICATIONS: Isolation and encapsulation of volatile flavor compounds (flavorants) from ghee—a fat‐rich heat desiccated milk product—for the development of low fat and cholesterol‐free food products would be a novel approach to provide the flavor of ghee to people who cannot consume it owing to health constraints. An understanding of both the functionality and flavor of the powder would help better use of the powder while developing food formulations. Besides, ghee flavorants such δ‐dodecalactone and δ‐tetradecalactone enriched powder would form a novel dairy ingredient in dairy, food, and pharmaceutical industries.

    Abstract In this research work, the dielectric properties of red banana fruit are studied at different ripening temperatures for developing a rapid and non-destructive assessment method to measure the ripening stages of red banana. A 5 volt sine wave AC power supply and a rectangular parallel plate capacitor circuit are used to measure the difference in dielectric properties caused by the introduction of a red banana in between the plates. The values of properties like capacitance and relative permittivity are increased continuously whereas impedance and admittance are decreased gradually with increase in ripening stages of red banana. In image processing approach, Noise Reductant Local Binary Pattern (NRLBP), Local Binary Pattern (LBP), Completed Local Binary Pattern (CLBP) based techniques are used for red banana’s ripening grade determination. The processing stages involved are enhancement, Binary Pattern generation and classification. The variant Binary patterns are tested on noisy as well as noiseless condition and the results are compared. A novel enhancement technique for banana ripening grade determination is proposed based on segmentation using Tsallis entropy. Also novel idea on the automation of q parameter involved in Tsallis Entropy is implemented. The threshold parameter of the Noise Reductant Local Binary Pattern (NRLBP) varied and its effect on classification rate is studied. A new modification is proposed and implemented on NRLBP to accommodate uniform background and areas with the image. Classification is done using Chi-Square distance/nearest neighbor and Fuzzy C means (FCM) clustering. The results are compared and superiority of FCM method for banana ripening grade determination is noted.

    Abstract Pesticides are either natural or chemically synthesized compounds that are used to control a variety of pests. These chemical compounds are used in a variety of sectors like food, forestry, agriculture and aquaculture. Pesticides shows their toxicity into the living systems. The World Health Organization (WHO) categorizes them based on their detrimental effects, emphasizing the relevance of public health. The usage can be minimized to a least level by using them sparingly with a complete grasp of their categorization, which is beneficial to both human health and the environment. In this review, we have discussed pesticides with respect to their global scenarios, such as worldwide distribution and environmental impacts. Major literature focused on potential uses of pesticides, classification according to their properties and toxicity and their adverse effect on natural system (soil and aquatic), water, plants (growth, metabolism, genotypic and phenotypic changes and impact on plants defense system), human health (genetic alteration, cancer, allergies, and asthma), and preserve food products. We have also described eco-friendly management strategies for pesticides as a green solution, including bacterial degradation, myco-remediation, phytoremediation, and microalgae-based bioremediation. The microbes, using catabolic enzymes for degradation of pesticides and clean-up from the environment. This review shows the importance of finding potent microbes, novel genes, and biotechnological applications for pesticide waste management to create a sustainable environment.
