Abstract

Purpose

Keeping in view the diabetes status that has affected about 415 million people globally and is the leading cause of death in many countries along with therising demand for low Glycemic Index (GI) foods, the purpose of this paper is to optimize the extrusion process for the development of low GI snacks from underutilized crops like water chestnut and barley.

Design/methodology/approach

The extrusion parameters (screw speed and barrel temperature), feed moisture and water chestnut flour, barley flour proportion, were varied and their effects on system and product responses (specific mechanical energy, water absorption index, water solubility index, bulk density, expansion ratio and breaking strength) were studied.

Findings

All the system and product responses were significantly affected by independent variables. Response surface and regression models were established to determine the responses as function of process variables. Models obtained were highly significant with high coefficient of determination (R2=0.88). The optimum processing conditions obtained by numerical optimization for the development of snacks were 90°C barrel temperature, 300 rpm screw speed, 14 per cent feed moisture and WCF-to-BF ratio as 90:10. Shelf life studies confirmed that the developed snacks can be safely stored in HDPE bags for a period of six months under ambient conditions.

Originality/value

Water chestnut and barley flour did not blend till date for extrusion cooking. Such snacks shall be a viable food option for diabetic people and can act as laxative due to high fibre and β-glucan content from barley.

Abstract

Purpose

This study aims to develop sweet chestnut incorporated corn-based extrudates by the optimization of process conditions.

Design/methodology/approach

The independent process variables for extrusion (blend ratio, barrel temperature, screw speed and feed moisture) were investigated to govern their impact on reliant variables, namely, bulk density, specific mechanical energy, water absorption index, water solubility index, color and hardness. Product and system responses were significantly (p < 0.05) affected by the independent variables. Experimental design with quadratic models experienced a high coefficient of determination (R2 = 0.99).

Findings

Numerical optimization for the development of extrudates resulted in optimum conditions having corn flour: sweet chestnut flour (80:20), barrel temperature (120°C), screw speed (340 rpm) and feed moisture (12%). Fat, moisture and protein contents of the developed extrudates using optimum conditions were significantly (p < 0.05) lower compared to raw materials – corn and sweet chestnut. The packaging of extrudates in aluminum laminates revealed shelf stability of three months at room temperature without deterioration of quality.

Originality/value

Nutritionally rich sweet chestnut extruded products would be an exclusive option to already existing snacks in the market and can facilitate a new sphere in extruded product sector.

The purpose of the present study was to develop low Glycemic Index (GI) crackers from water chestnut flour (WCF) and barley flour (BF).

Abstract

Purpose

The purpose of the present study was to develop low Glycemic Index (GI) crackers from water chestnut flour (WCF) and barley flour (BF).

Design/methodology/approach

Five blends were prepared by mixing WCF with BF in the proportion of 100:0, 70:30, 50:50, 30:70 and 0:100, respectively. The baking process as well as ingredients were modified for the production of low GI crackers.

Findings

BF incorporation had significant (p < 0.05) effect on physical characteristics, organoleptic attributes and glycemic response of crackers. The resistant starch content of final product was found to be higher than WCF and BF. The research confirmed that replacement of 30 percent WCF with BF is feasible for development of low GI crackers with desired sensory attributes. The inference drawn from storage studies was that the developed crackers can be stored safely (with an overall acceptability score of greater than three on a 5-point scale) in metallized polyethylene up to 35 days under refrigerated conditions and 28 days under ambient conditions.

Research limitations/implications

Although low GI crackers were developed successfully from WCF and BF in the present study. However, detailed storage studies of such crackers can be done in future so as to perform the tests of type-intensity and temporal dominance of sensation. Also, in view of their low GI, these crops need to be evaluated in future for development of other bakery products like bread, cake, muffins, etc.

Practical implications

Water chestnut and barley despite having good nutritional profile and low GI are still considered as underutilized crops. In the present study, these crops were explored for development of low GI crackers especially for people suffering from diabetes. The outcome of this study will open up a new window in the baking sector to develop low GI crackers viz-a-viz will add value to these crops which will help to provide remunerative returns to those who are directly or indirectly involved in trade of these underutilized crops.

Originality/value

This was the first reported innovative attempt to develop low GI crackers from WCF and BF. For development of crackers having desired sensory characteristics, it was found feasible to blend WCF and BF in the ratio of 70:30.

Abstract

Purpose

Throughout the world, there has been a dramatic increase in the demand for functional food products. Owing to the health benefits of barley, its utilization was explored for the development of β-glucan rich functional instant talbina (porridge). The present research was, therefore, undertaken with an aim to optimize the extrusion conditions for development of instant talbina premix and evaluate its functional and quality characteristics.

Design/methodology/approach

The independent variables i.e. barrel temperature (105–125°C) and feed moisture (12–20%) were studied to determine their influence on the system parameter i.e. specific mechanical energy and product characteristics i.e. bulk density, breaking strength, water absorption index, expansion ratio, water solubility index, L*, a* and b* by employing a central composite rotatable design.

Findings

All the quality parameters were significantly (p < 0.05) influenced by independent variables. The regression models obtained for all the responses showed higher coefficient of determination (R2 = 0.99). The optimum extrusion conditions obtained by numerical optimization for development of extrudates used for making instant talbina were moisture content (12%) and barrel temperature (105°C). Various functional, pasting, complexing index and physicochemical properties of instant talbina were improved by the addition of honey and milk. The instant talbina prepared from barley flour with the addition of milk and honey showed increase in the β-glucan content, resistant starch, antioxidant activity and decrease in glycemic index with improved overall acceptability.

Originality/value

As far as we could possibly know that very limited or not many studies have been carried out wherein the possibility of developing instant talbina (porridge) have been carried out. As a result, the current study has a lot of potential for the food industry to manufacture β-glucan rich functional instant talbina with improved antioxidant characteristics and low glycemic index.

Abstract

Purpose

The present research was envisaged with an aim to optimize the system and the product responses for the development of tomato pomace-incorporated corn-based extrudates employing central composite rotatable design and determine its proximate, lycopene, consumer acceptability and storage studies.

Design/methodology/approach

Lycopene-rich extrudates were developed from corn flour blended with different levels of tomato pomace. The independent extrusion variables, namely, feed composition (95:5 to 75:25), feed moisture (12–20%), screw speed (200–600 rpm) and barrel temperature (125–185 °C), were studied to determine their influence on dependent variables, namely, specific mechanical energy, hardness, water solubility index, lateral expansion, water absorption index, bulk density and color.

Findings

All of the quality parameters were significantly (p < 0.05) influenced by independent variables. The regression models obtained for all the responses showed high coefficients of determination (R2 = 0.85–0.95). The optimum conditions for the development of tomato pomace-incorporated corn-based extrudates were feed composition (90:10), feed moisture (14%), screw speed (300 rpm) and barrel temperature (170 °C). The moisture, fat and carbohydrate contents of the extrudates were significantly reduced, whereas protein, ash and fiber were significantly (p < 0.05) enhanced after the incorporation of tomato pomace. Aluminum laminates were found to be the suitable packaging materials for extrudates for a period of 120 days in comparison to high-density polyethylene packages.

Originality/value

As far as the authors could possibly know, scanty literature exists wherein the tomato pomace has been utilized for the development of lycopene-rich corn-based extruded snacks. Such extrudates with significantly higher fiber and lycopene contents than corn flour will serve as a suitable alternative for the development of shelf-stable ready-to-eat extruded snacks.

Abstract

A standard wholemeal loaf is now on sale. It is made of flour of 85 per cent. extraction, and the Ministry of Food has arranged with the millers and bakers for the immediate production of both flour and bread in quantities sufficient, it is hoped, to meet all demands. The 85 per cent. extraction of this new national wholemeal flour compares with a figure of 73 per cent. for ordinary white flour, and the new flour will produce a more nutritious loaf. The Ministry of Food is satisfied after research by its experts that 85 per cent. extraction flour provides maximum digestibility and nutriment. Steps will be taken to see that the new bread is available everywhere, and at the same price as white bread. This is now 8d. a 4lb. loaf, and the Government are making a subsidy so that the price shall be kept at this figure. So far, although nearly three months have passed since it was decided to grant the subsidy, the bakers have not received it ; but agreement on the scheme has now been reached between them and the Ministry, which states that an early announcement will be made. Special breads, such as those containing more fat, which are popular in the North, may be sold for more than 8d., but these do not then qualify for the subsidy. The decision to make a standard wholemeal loaf and wholemeal flour available in large supply was taken because it was found that a substantial proportion of the population wanted them. Existing brown breads vary enormously ; the new loaf will be a standard product. Meanwhile, the Ministry is going ahead with its scheme for introducing flour reinforced with manufactured vitamin B1, but this will not be available for some months.

Low glycemic index gluten-free cookies from high amylose rice flour were prepared by modifying baking conditions and ingredient composition.

Abstract

Purpose

Low glycemic index gluten-free cookies from high amylose rice flour were prepared by modifying baking conditions and ingredient composition.

Design/methodology/approach

Baking temperature, baking time, and concentration of carboxymethyl cellulose (CMC) were varied between 170 and 190° C, 12–25 min, and 0.2–1%, respectively, using central composite rotatable design. The developed cookies were packed in metalized polyester pouches and stored under ambient conditions for a period of 90 days.

Findings

Width and bulk density of cookies increased significantly (p < 0.05) with an increase in baking temperature, while thickness, baking loss and yield decreased with an increase in baking temperature. Puffiness increased predominantly with the increase in the concentration of CMC. Design expert predicted baking temperature of 185° C, baking time of 22 min, and 0.8% concentration of CMC as desirable conditions for the development of gluten-free cookies from rice flour. Cookies developed after following optimized conditions recorded dietary fiber of 4.66%, resistant starch (RS) content of 7.20% and predicted glycemic index (pGI) of 44.60. RS, pGI, moisture, water activity, free fatty acids and peroxide value increased significantly, whereas hardness and overall acceptability decreased during storage.

RPractical implications

Gluten-free (GF) foods are in high demand globally due to the prevalence of celiac disease. Rice lacks gluten protein, and thus, can serve as a potential raw material for the development of GF cookies. In the present study, the ingredient modification and freezing interventions during baking were found to be crucial if the development of low GI gluten-free cookies having good RS content is targeted. Optimized GF cookies prepared via technological intervention and packed in metalized polyester were shelf stable for up to 3 months under ambient conditions. Furthermore, resistant starch content was enhanced while the predicted glycemic index was decreased during storage. Adoption of baking conditions and CMC level optimized in the present study can help to develop shelf-stable GF bakery products for people suffering from comorbidities like celiac disease and diabetes.

Originality/value

Resistant starch content was enhanced while predicted glycemic index was decreased during storage of gluten-free cookies prepared from high amylose rice flour. The developed cookies can be a complementary diet to people suffering from comorbidities like celiac disease and diabetes.

Abstract

This Food Standards Committee Report has been with us long enough to have received careful appraisal at the hand of the most interested parties — food law enforcement agencies and the meat trade. The purposes of the review was to consider the need for specific controls over the composition and descriptive labelling of minced meat products, but the main factor was the fat content, particularly the maximum suggested by the Associaton of Public Analysts, viz., a one‐quarter (25%) of the total product. For some years now, the courts have been asked to accept 25% fat as the maximum, based on a series of national surveys; above that level, the product was to be considered as not of the substance or quality demanded by the purchaser; a contention which has been upheld on appeal to the Divisional Court.

Abstract

Purpose

This study examines liberal second-wave feminists’ writings about cooking. Most scholarship of liberal feminism has focused on the attempts to integrate women into previously male-dominated public spaces such as higher education, the professions, and political office. Less attention has been paid to how these feminists politicized feminized spaces such as the home. A longstanding tension between the housewife role and feminist identities has led many to theorize that feminists avoid or resent domestic tasks. However, I argue that some liberal feminists in the 1960s, 1970s, and 1980s suggested engaging with cooking in subversive ways that challenged patriarchal institutions and supported their political goals.

Methodology/approach

I analyze 148 articles about cooking in Ms. magazine between 1972 and 1985. I also analyze the copy and recipes within four community cookbooks published by liberal feminist organizations.

Findings

I find that liberal feminists suggested utilizing time- and labor-saving cooking methods, encouraged men to cook, and proposed that women make money from cooking. These three techniques challenged the traditional division of domestic labor, supported women’s involvement in the paid workplace, and increased women’s control of economic resources.

Originality/value

This study turns the opposition between feminism and feminized tasks on its head, showing that rather than avoiding cooking, some liberal feminists proposed ways of cooking that challenged patriarchal institutions. I show how subordinate populations can develop ways of subversively engaging with tasks that are typically seen as oppressive, using them in an attempt to advance their social position.
