Abstract

Purpose

The purpose of this paper is to screen cytotoxic activities of commonly used culinary plants in Malaysia, Pandanus amaryllifolius (daun pandan), Curcuma longa (turmeric leaves) and Etlingera elatior (kantan flower) against selected cancer cell lines.

Design/methodology/approach

Plant samples were extracted exhaustively with ethanol and concentrated under rotary evaporator. Cytotoxic evaluation was carried out with plant extracts (0‐100 μg/ml) using 72‐h MTT assay.

Findings

Exposure of plant extracts reduced cell viability of HepG2 (hepatocellular carcinoma), HT‐29 (colon carcinoma), MDA‐MB‐231 (non‐hormone‐dependent breast cancer), MCF‐7 (hormone‐dependent breast cancer) and HeLa (cervical cancer); 50 percent inhibitory values (IC50) were obtained for MDA‐MB‐231, HepG2, HT‐29. Extracts within the concentrations of 10‐100 μg/ml were found not to be effective against proliferation of MCF‐7 and HeLa.

Originality/value

The paper shows how culinary plants – daun pandan, turmeric leaves and kantan flower displayed selective cytotoxic effects towards liver, colon and breast cancer in vitro.

Abstract

Purpose

The utilization of oilseeds in food formulations is prevalent due to their health benefits and nutritional value. These protein-rich oilseeds serve as an affordable and essential source of nutrients and bioactive compounds, fulfilling human protein requirements. As such, this study sought to investigate the impact of partially replacing wheat flour with oilseeds in different proportions on the nutritional and quality characteristics of biscuits.

Design/methodology/approach

Oilseeds, including terebinth, sesame and flaxseed, were partially substituted with wheat flour in amounts of 0, 5, 10, 15, 20 and 25%. The effects of this substitution on the storage stability, nutritional content and physical properties of the resulting biscuits were examined.

Findings

The L* (from 69.75 to 54.06) and b* (from 28.59 to 21.60) color values of biscuits decreased with the supplement of oilseeds. The oilseeds addition increased the protein, fat, energy, and ash values of biscuits. At the highest level of added terebinth, sesame and flaxseed, respectively, the amounts measured were 5984.62 mgGAE/kg, 1553.85 mgGAE/kg and 2169.23 mgGAE/kg, which were higher than the control biscuits (715.39 mgGAE/kg). The incorporation of oilseeds resulted in a substantial decrease in pH and peroxide values, while the moisture content was increased throughout the 6-month storage period. The use of terebinth in biscuits led to better oxidative stability than sesame and flaxseed-containing samples. The biscuit samples with terebinth had a longer induction time. The lowest induction time of biscuits with 25% flaxseed was chosen, approximately 3.5 h.

Research limitations/implications

Oilseed flours, which are rich in lipids, have been shown to enhance the quality of biscuits. However, further studies could aim to reduce the amount of shortening used to improve their quality even further. Reducing the shortening could keep the lipid content at an acceptable amount, especially considering consumers' current expectations for low-fat foods.

Practical implications

Plant-based bioactive are generally known as secondary metabolites and have promising therapeutic attributes, especially antioxidative properties.

Social implications

Thanks to this composition, some of these seeds have proven effective in controlling and preventing metabolic diseases (hypertension, hypercholesterolemia, diabetes, coronary heart disease and several types of cancer) as well as providing interesting properties to foods.

Originality/value

As result, oilseeds can be successfully used as functional and sustainable food ingredients to improve the functional, nutritional and storage stability of biscuits.
