香りの科学 Does a Nectarless Orchid Smell Like Its Neighbors?
Comparing scent compounds in a rewardless orchid and surrounding flowers reveals shared constituents and different blend proportions, offering clues to insect attraction.
香りの科学 Does Increasing Chromosome Sets Change Floral Scent?
A comparison of naturally derived diploids and tetraploids with newly created polyploids examines immediate scent changes separately from later evolution.
香りの科学 How Do Oil-Collecting Bees Find Flowers?
What cues guide bees that collect floral oils? A study of diacetin explores a possible connection between floral resources and bee olfaction.
香りの科学 Can Bees Recognize Floral Scents Changed by the Air?
Can bees recognize floral scents altered in the atmosphere? A modeling study combines molecular features and earlier behavioral data to predict effects on four crops.
香りの科学 Can Bees Follow Floral Scents after Heat and Dryness?
Bees exposed to heat and dryness were less likely to begin exploring. This study distinguishes antennal responses that detect scent from behavior directed toward it.
香りの科学 Can Yeast Adjust the Constituent Ratios of Sandalwood’s Aroma?
Can yield and constituent ratios be balanced when producing sandalwood-related compounds in yeast? A 2022 study combines enzyme modification with metabolic engineering.
香りの科学 Can Yeast Make Fragrance Ingredients Not Found in Nature?
Research on producing fragrance ingredients by fermentation goes beyond recreating aromas found in plants. A reported method changes the molecular building blocks used by yeast to produce carbon skeletons outside the usual natural forms. For ethyllinalool, it selectively produces one of two forms with different scent characteristics.
香りの科学 Does the Extraction Method Change Rosemary’s Constituents?
What is obtained from rosemary changes depending on whether it is distilled with water, transferred into olive oil, or extracted with supercritical CO₂. A comparison of three methods shows why the extraction process and product form matter, not just the plant’s name.
香りの科学 Is There Value in the Water Left after Essential Oil Extraction?
Plant-derived constituents remain in the water after lavender essential oil extraction. This study compared essential oils and by-products from two extraction methods to explore their potential as resources.
