It has been established that the degree of their swelling depends on the type of a medium (water, albumin solution, fat) and the state of seeds (whole seeds or ground seeds). It was noted that the whole seeds have a higher capacity to retain water than the ability to retain an albumin solution or fat, by 1.87 and 17.28 times, and the ground seeds – by 1.75 and 17.49 times, respectively. Their capacity to swell improves after grinding regardless of the type of a medium. In addition, the ground seeds have a better fat-emulsifying ability but they do not demonstrate the foaming properties. The whole chia seeds have good foaming properties. It is possible to obtain a whipped protein mass, which is not worse than the control sample in terms of stability and foaming capacity, in case of replacing 40 % of dry albumin with whole chia seeds. We recommend adding the whole chia seeds at the stage of the whipping of protein mass, and the ground seeds – at the stage of obtaining a fat emulsion semi-finished product in the production of cream-whipped candy masses. Thus, the formulation amount of dry albumin and fat decreases. The addition of 30 % of whole seeds and 30 % of ground seeds helps reduce the density of structured cream-whipped candy mass by 6.7 %. A further increase in the dosage of the additive leads to a slight increase in the value of the density indicator. In addition, an increase in the content of chia seeds causes an increase in the strength indicator of samples. The organoleptic analysis showed that the structured cream-whipped candy masses with the most studied dosage of chia seeds have the densified structure, uneven porosity, and strong, viscous consistency. It was found that the dosage of whole seeds should equal 40 % by weight of egg albumin, and the dosage of ground seeds – 40 % by weight of fat to ensure the high quality of cream-whipped candy masses. The obtained results are of practical importance for improving the technology of cream-whipped candy masses towards decreasing the formulation amount of albumin and margarine. The addition of chia seeds would improve the nutritional and biological values of cream-whipped candies","PeriodicalId":448930,"journal":{"name":"SRPN: Nutrition (Topic)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133352115","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Making Pulses Affordable Again: Policy Options from the Farm to Retail in India","authors":"P. Joshi, A. Kishore, D. Roy","doi":"10.21955/GATESOPENRES.1115399.1","DOIUrl":"https://doi.org/10.21955/GATESOPENRES.1115399.1","url":null,"abstract":"Rising prices and declining consumption of pulses cause concern in terms of both nutrition and food inflation in India. This paper outlines policy strategies to increase the availability of pulses at affordable prices in India and also points out limitations of some of the most common recommendations for achieving these objectives. There seems to be no option but to increase domestic production of pulses in India. The global supply of pulses is limited compared with India’s needs, and sizable imports by India are bound to increase world prices. Domestic production of pulses in India is most likely piecewise inelastic, meaning that small price increases do not translate into a significant supply response. Because farmers face both production and marketing risks, they increase pulse area and intensify production only when there is a large increase in expected prices that covers the risk premium. Droughts, too, are a major risk for pulses. Access to one or two protective irrigations during the growing season can possibly lead to sizable increases in pulse production and reduce the production risk. The har khet ko paani (assured irrigation) initiative under the Pradhan Mantri Krishi Sinchayee Yojana (PMKSY) program should give priority to pulse-producing areas. The minimum support price (MSP) for pulses, without direct government procurement, helps traders more than farmers because it acts as a focal point for tacit collusion among traders. Farmers will benefit from the MSP only if it is raised substantially from its current levels. The increase in farmgate prices due to a higher MSP will not necessarily lead to an increase in the retail price of pulses because much of the wedge between farmgate prices and consumer prices is traders’ margin. Including subsidized pulses in public distribution systems can save households some money, but it has only a small effect on total consumption of pulses and almost no effect on total protein intake. We suggest, as more potent solutions, investing in research and extension for pulses, aggregating pulse growers into farmer producer organizations, and paying pulse growers or pulse-growing areas for the ecosystem services offered by pulses.","PeriodicalId":448930,"journal":{"name":"SRPN: Nutrition (Topic)","volume":"107 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132871161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
