This systematic review aims to gain the studies regarding the effect of Nigella Sativa (N. sativa) on adipokines including leptin, adiponectin and resistin.

Abstract

Purpose

This systematic review aims to gain the studies regarding the effect of Nigella Sativa (N. sativa) on adipokines including leptin, adiponectin and resistin.

Design/methodology/approach

Search was carried out using databases Scopus, Web of Science, PubMed and Google Scholar with no restriction on language or date until February 2023 and alert services were applied to identify any paper after the primary search.

Findings

Eighteen animal and human studies were eligible for the current systematic review. Leptin and resistin levels showed a downward tendency after consuming N. sativa and its ingredients [e.g. oil, thymoquinone (TQ) and thymol] as well as its extracts (e.g. water extract). Furthermore, considering 4 of 8 animal research studies and 2 of 5 human studies that evaluated adiponectin levels, a significant increase was observed after using N. sativa and its ingredients (e.g. oil, TQ and thymol).

Originality/value

The present paper collates evidence from animal and human studies regarding the effect of N. sativa on adipokines including leptin, adiponectin and resistin.

The present study provides evidence on export advantages of horticultural commodities based on competitiveness, trade balance and seasonality dimensions.

Abstract

Purpose

The present study provides evidence on export advantages of horticultural commodities based on competitiveness, trade balance and seasonality dimensions.

Design/methodology/approach

The study delineated horticultural commodities in terms of comparative advantage, examined temporal shifts in export advantages (mapping) and estimated seasonality. Product mapping was carried out using the Revealed Symmetric Comparative Advantage (RSCA) and Trade Balance Index (TBI). Seasonal advantages were examined through a graphical approach along with the objective tests, namely, modified QS-test (QS), Friedman-test (FT) and using a seasonal dummy.

Findings

Cucumbers/gherkins, onions, preserved vegetables, fresh grapes, shelled cashew nuts, guavas, mangoes, and spices emerged as the most favorable horticultural products. India has a strong seasonal advantage in dried onions, cucumber/gherkins, shelled cashew nut, dried capsicum, coriander, cumin, and turmeric. The untapped potential in horticulture can be addressed by handling the trade barriers effectively, particularly the sanitary and phytosanitary issues, affecting the exports. Proper policies must be enacted to facilitate the investment in advanced agricultural technologies and logistics to ensure the desired quality and cost effectiveness.

Research limitations/implications

Commodity-specific studies on value chain analysis would provide valuable insights into the issues hindering exports and realizing the untapped export potential.

Originality/value

There is no holistic and recent study illustrating the horticulture export advantages covering a large number of commodities in the Indian context. The study would be helpful to the stakeholders for drawing useful policy implications.

Abstract

Learning outcomes

After completion of this case study, students will be able to apply the triple bottom line concept to a spice manufacturing and export company (RBT 3); to examine the options before Value Ingredients Private Limited (VIPL), namely, to cultivate spices in the traditional way versus adopting integrated pest management (IPM) to cater to international markets (RBT 4); to analyse the returns for an IPM farmer vis-à-vis a conventional farmer, and to compare the returns therein (RBT 4); and to evaluate the ways and means of engaging farmers to change their way of cultivation (RBT 5)

Case overview/synopsis

The COVID-19 pandemic heightened awareness about the benefits of spices and buoyed its demand worldwide, which presented an opportunity to VIPL, a spice manufacturing company based in Chennai, to expand its business. However, the export markets demanded residue-free spices grown with little or no use of pesticides. Traditional farmers supplying spices to VIPL were accustomed to spraying pesticides whenever there was a pest attack. This case study discussed the options that the protagonist Mr Sijil Karim, managing director and CEO of VIPL, had, who wanted to onboard farmers for pesticide-free cultivation. The options before him were either to continue traditional farming or adopt IPM. This case study discussed the merits, demerits and challenges of each of these options.

The triple bottom line concept discussed three Ps – people, planet and prosperity – for this case as follows: The farmers and the consumers constituted the people in the spice supply chain. The farmers supplying organic, export-worthy spices under the guidance of VIPL gained 30% more than regular spice farmers, which were accrued through cost savings and better prices. The consumers benefitted from the pesticide-free, organic spices through accrued health gains. The manufacture of organic, pesticide-free spices helped the planet, as the process did not release hazardous chemicals into the atmosphere. VIPL manufactured pesticide-free spice with a focus on prosperity.

Complexity academic level

The case study can be introduced in a course on sustainability while discussing the triple bottom line concept. This case study showed how a for-profit company grew without losing sight of the planet or its focus on people. This case is best suited for students who have preliminary knowledge of supply chain management, operations and sustainability. Therefore, it is suited for sophomore-year students of MBA.

Abstract

Purpose

The objective of this study was to assess the incorporation of polyunsaturated omega 3 and omega 6 fatty acids in the eggs of Japanese quails (Coturnix coturnix japonica) fed with soybean, flaxseed and shark liver oils, as well as to assess their effects on the chemical composition and lipid quality of the yolks.

Design/methodology/approach

The total of 252 units of quails were distributed in a completely randomized design with seven treatments and six replications, totaling 42 experimental design units. The sources of oils and their inclusions in the experimental diet were 2% of soybean oil (S), 2% of flaxseed oil (L) and 2% shark liver oil (T), obtained from the species Carcharhinus acronotus, and the mixtures of 1% S + 1% L (SL); 1% S + 1% T (ST); 1% L + 1% T (LT) and 0.67% S + 0.67% L + 0.67% T (SLT).

Findings

The proximate composition of the egg yolk was not changed to the supplementation of lipid sources added in quail diet. The total replacement of soybean oil by shark liver oil reduced the cholesterol content in the yolk by 19% (T = 282.97 mg cholesterol/100 g egg) and the addition of flaxseed oil produced eggs with greater amount of polyunsaturated fatty acids (PUFAs) (LS = 18.32%). The treatments with flaxseed oil and its mixtures (soybean oil + flaxseed oil and flaxseed oil + shark liver oil) effectively contributed to reducing the ω-6:ω-3 ratio and enriching the quail eggs with PUFAs, especially linolenic acid (18: 3n3c) and EPA (20: 5n3c).

Originality/value

Thus, manipulation in the diet of quails enriched the content of essential PUFAs and reduced the cholesterol content in the yolk. The flaxseed oil was the lipid source that influenced to improve the quality of the egg yolk. These results have practical applicability for the quail egg industry.
